BACKGROUND: Suicide is the second leading cause of death in 12- to 17-year-old adolescents in the USA. Research on biological mechanisms contributing to self-harm risk that could be targeted in treatment could help to prevent suicide and self-harm episodes. AIMS: We aimed to evaluate whether markers of inflammation, interleukin-6 (IL-6) and C-reactive protein (CRP), predict self-harm over 3 months within a sample selected for elevated suicide/self-harm risk at project entry. METHOD: Fifty-one adolescents aged 12-19 years selected for elevated suicide/self-harm risk completed three clinical interviews about suicide attempts and non-suicidal self-injury, 3 months apart. At baseline and 3 months, youth also provided blood samples, from which we assayed levels of IL-6 and CRP. RESULTS: Using generalised mixed models, we found that greater levels of IL-6 predicted more self-harm episodes (odds ratio [OR] = 3.3, 95% CI: 1.1, 10.0) and specifically, non-suicidal self-injury (OR = 3.5, 95% CI: 1.1, 11.2), over 3 months. CONCLUSIONS: The study findings increase our understanding of whether and how inflammation may be implicated in risk of self-harm. IL-6 may be a viable biological marker of short-term risk for self-harm.

Introduction Methods Results Conclusions As suicide remains a global public health concern, recent work has sought to characterize mechanisms underlying the transition from suicidal ideation to action. Acquired capability for suicide, or fearlessness about death, has been identified as one key factor underlying this transition; however, understanding how this capability emerges remains limited. This study sought to extend previous work on the correlates of fearlessness about death by examining its relationship with painful and provocative events and emotional reactivity.We tested the extent to which trait emotional reactivity and past self‐injurious behavior moderated the relationship between assaultive trauma exposure and fearlessness about death in a diverse sample of 273 community adults (aged 18–55, M/SD = 32.77/10.78).A three‐way interaction emerged, such that among individuals with heightened emotional reactivity and a history of self‐injurious behavior (suicide attempt or non‐suicidal self‐injury), assaultive trauma was associated with increased fearlessness about death. In contrast, among adults with low emotional reactivity and a history of self‐injurious behavior, assaultive trauma was associated with reduced fearlessness about death.Results suggest that emotional reactivity may be a key dispositional factor that influences how trauma exposure and self‐injurious behavior impact fearlessness about death.

This study delves into the correlation between childhood trauma and non-suicidal self-injury (NSSI) behaviors among high school students. Additionally, it examines the mediating role of stress perception and the moderating role of the teacher-student relationship in this association. A questionnaire survey was administered to 1,329 high school students in Yunnan Province to assess childhood trauma, NSSI behaviors, and stress perception. Firstly, the survey revealed a 12% prevalence of NSSI, with girls exhibiting a higher occurrence compared to boys (OR = 0.413, 95% CI: 0.280–0.609). Secondly, childhood trauma emerged as a significant predictor of NSSI behavior, irrespective of gender or whether the individual was an only child (r = 0.17, P < 0.01). Thirdly, stress perception functioned as a mediator in the relationship between childhood trauma and NSSI among high school students (t = 4.65, P < 0.01). The mediation effect occupies 26.56% of the total effect. Furthermore, the teacher-student relationship moderated the mediating effect of stress perception on the link between childhood trauma and NSSI (β = 0.0736, P < 0.01). Notably, individuals with strong teacher-student relationships exhibited a significant elevation in stress perception upon exposure to childhood trauma. The findings of this study support a moderated mediation model in the association between childhood trauma and NSSI, suggesting profound implications for the development of targeted interventions and prevention strategies among high school students.

Background: Global centers of epidemic prevention and control have entered a new stage of normalization, namely, the "post-COVID-19 era." During the post-COVID-19 era, which is characterized by the time period following that with the most serious medical consequences, the psychosocial consequences of the COVID-19 pandemic began to receive worldwide attention, especially the degree of psychological distress it caused. Aim: This study explored the differential impact of gender role conflict on Chinese university students' engagement in nonsuicidal self-injury (NSSI) as a function of biological sex following the global COVID-19 pandemic. Methods: Participants were 1,600 university students in northwestern China (Mage = 21.3 years; 50.8% women) who completed online measures of demographic variables (including biological sex, gender role conflict, and NSSI engagement). Results: Women reported significantly more gender role conflicts than men did, while engagement in NSSI was significantly more prevalent among men than women. A total of 262 men reported engaging in at least one NSSI behavior, resulting in a prevalence rate of 33.25%. In comparison, a total of 106 individuals reported engaging in at least one NSSI behavior, resulting in a prevalence rate of 13.05% among women. Gender role conflict was found to significantly predict university students' NSSI engagement, regardless of biological sex. Conclusion: This is the first empirical study to identify sex differences in both gender role conflict and engagement in NSSI among university students in Northwestern China during the post-COVID-19 era. In addition, the present study is the first to demonstrate how gender role conflict predicts engagement in NSSI across sexes. These findings will inform the literature on gender role conflict and NSSI, particularly the close relationship between gender role conflict and engagement in NSSI among Chinese university students, and they emphasize the need for continued efforts to explore NSSI cross-culturally.

Based on previous empirical evidences and theoretical framework, sleep problems and non-suicidal self-injury (NSSI)/suicidal behavior may bidirectionally related to one another. However, this still needs to be examined through longitudinal research. Moreover, the mediating mechanisms accounting for their potential bidirectional relations have yet to be fully investigated. This study thus aimed to evaluate whether sleep problems and NSSI/suicidal behavior promoted each other directly or indirectly through the mediating roles of emotion regulation difficulties (ERD) and externalizing problems. A total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82; Age range = 11–16 years old at T1) completed self-report measures on 3-time points across 1 year. Cross-lagged panel models were used to examine the focal longitudinal associations. Results revealed a predictive effect of sleep problems on NSSI and a positive bidirectional relation between sleep problems and suicidal behavior. Moreover, sleep problems exerted an indirect effect on NSSI through ERD, and vice versa. Additionally, both ERD and externalizing problems served as mediators in the pathway from suicidal behavior to sleep problems. This study disentangled the differential mediating roles of ERD and externalizing problems in the longitudinal associations between sleep problems and NSSI/suicidal behavior, which may help provide a more holistic theoretical framework through which to precisely identify key targets for early prevention and intervention of sleep problems and NSSI/suicidal behavior in adolescents.

Background Methods Results Conclusions Non‐suicidal self‐injury (NSSI) in early adolescence has been amply documented. However, there has been little research on the progression of NSSI over time. Most studies have focused on the risk factors for NSSI, with less attention devoted to understanding the role of protective factors. This paper aimed to expand existing knowledge about the development of NSSI, with an emphasis on the impacts of protective factors such as social support and socioeconomic status (SES).A total of 436 adolescents completed self‐report surveys that addressed social support including friend, family, and teacher support, objective and subjective SES, and NSSI at three different points in time for 2 years.Latent growth curve analyses revealed that NSSI increased across early adolescence to mid‐adolescence. Support from friends and family negatively predicted adolescents' initial NSSI level. Furthermore, subjective SES negatively predicted the rate of NSSI.These findings contribute to an understanding of the influences of both social support and SES on NSSI over time. NSSI interventions and education should include considerations of both the value of support from friends and family as well as subjective SES. [ABSTRACT FROM AUTHOR]

The present study explored differences in four domains of university adjustment (i.e. personal-emotional, social, academic, and institutional attachment) among students with and without a history of engaging in non-suicidal self-injury (NSSI) and examined the independent influence of NSSI on university adjustment. Participants were 231 students from a large Canadian university who completed an online survey during their first and second year of university examining their perceived stress, perceived social support, coping self-efficacy, and university adjustment. Relative to students who never engaged in NSSI, those who did reported lower levels of university adjustment across domains. However, NSSI was not a significant predictor of university adjustment after accounting for perceived stress, perceived social support, and coping self-efficacy. This study provides preliminary evidence that engaging in NSSI may not confer additional risk for university adjustment, as students' psychological resources appear to be stronger determinants of adjustment.

The COVID-19 pandemic has dramatically altered the way of life in the United States, which may be linked to self-injurious behaviors. We conducted a secondary analysis of data from the Fall 2020 Cohort of the Healthy Minds Survey, a non-probability sample of students enrolled at one of 28 universities across the United States. Participants completed an online survey during the COVID-19 pandemic (September–December, 2020). Nearly a quarter of the sample (n = 6999) reported engaging in non-suicidal self-injury (NSSI), 12.41% (n = 3819) reported suicidal ideation, 4.98% (n = 1531) reported making a suicide plan, and 1.09% (n = 334) reported a suicide attempt over the past 12 months. When accounting for all COVID-19 factors in the same model, COVID-19 related concern, COVID-19 related discrimination, financial distress, and infection were significantly associated with NSSI, suicidal ideation, and suicide plan; caregiving was significantly associated with lower odds of engaging in non-suicidal self-injury. None of the factors were associated with suicide attempt. This study showed that various COVID-19 factors were related to SIB. Interventions may consider multiple dimensions of COVID-19 and their specific impacts. [ABSTRACT FROM AUTHOR]

A meta-analysis was performed to determine pooled prevalence of non-suicidal self-injury (NSSI), suicide behaviors (including ideation, attempts), and associated risk factors among runaway and homeless youth (RHY). The databases PubMed, Scopus, Web of Science, and Cochrane Library were searched for relevant studies published from January 1995 to May 2023. Initially, 8465 papers were screened, resulting in 69 included studies. The results showed that among RHY, lifetime prevalence rates were 42% for NSSI, 38% for suicidal ideation, and 27% for suicide attempts. Lifetime prevalence of NSSI and suicide behaviors was higher among adolescent minors (aged 12–17 years) compared to young adults (aged 18–24 years). Also, NSSI and suicide behaviors were associated with having a childhood history of physical and sexual abuse. Developing an impactful community-based suicide prevention campaign tailored for RHY appears warranted. Peer groups and mentorship programs would provide invaluable support for young individuals, as supportive friendships protect against NSSI. [ABSTRACT FROM AUTHOR]

Existing research on non-suicidal self-injury (NSSI) among adolescents has primarily concentrated on general risk factors, leaving a significant gap in understanding the specific NSSI characteristics that predict diverse psychopathological outcomes. This study aims to address this gap by using Random Forests to discern the significant predictors of different clinical outcomes. The study tracked 348 adolescents (64.7% girls; mean age = 13.31, SD = 0.91) over 6 months. Initially, 46 characteristics of NSSI were evaluated for their potential to predict the repetition of NSSI, as well as depression, anxiety, and suicidal risks at a follow-up (T2). The findings revealed distinct predictors for each psychopathology. Specifically, psychological pain was identified as a significant predictor for depression, anxiety, and suicidal risks, while the perceived effectiveness of NSSI was crucial in forecasting its repetition. These findings imply that it is feasible to identify high-risk individuals by assessing key NSSI characteristics, and also highlight the importance of considering diverse NSSI characteristics when working with self-injurers.

Objective: Non-suicidal self-directed violence (NSSDV) is a significant and growing youth public health crisis. Girls with ADHD are at increased risk of engaging in NSSDV, yet qualitative studies with this population—to better understand manifestations, motivations, and developmental course—are lacking. Method: We conducted semi-structured, qualitative interviews with a sub-sample of 57 young women (32 with childhood ADHD, 25 neurotypical comparisons; mean age of 27 years, part of a larger prospective longitudinal study) regarding histories and manifestations of NSSDV. Results: Inductive and deductive analysis revealed several key themes, including self-perceived reasons for engaging in NSSDV (affect regulation, attention seeking, self-punishment, asserting control), impulsivity, secretiveness, and in some cases motivations for desistance. Conclusion: Findings underscore the importance of early education and screening, especially among high-risk clinical populations. Increased resources and supports for professionals, parents, and peers are indicated, along with countering the persistent stigma associated with ADHD and NSSDV. [ABSTRACT FROM AUTHOR]

Background: Non-suicidal self-injury (NSSI) has exhibited an increasing trend in recent years and is now globally recognized as a major public health problem among adolescents and young adults. Negative life events (NLEs) are positively associated with NSSI. We sought to explore (1) whether sex plays a role in the risk of NLEs leading to NSSI and (2) the role played by mental health (MH). Methods: We adopted a multi-stage cluster sampling method to select college students across four grades from May to June 2022. Generalized linear models were used to evaluate the relationships between NLEs, sex, MH and NSSI, presented as incidence-rate ratios (RRs) with 95% confidence intervals (CIs). We examined the complex relationship between these variables using the PROCESS method for moderation analysis. Results: Following the exclusion of data that did not meet the study requirements, data from 3,578 students (mean age: 20.53 [± 1.65] years) were included. Poisson regression results indicate that high-level NLEs (RR = 0.110, 95%CI: 0.047–0.173) are associated with increased NSSI. Furthermore, interaction effects were observed among sex, NLEs and NSSI. MH and sex moderated the relationship between NLEs and NSSI. Conclusion: Identifying risk factors for NSSI is also important when exploring the interaction between NLEs and MH given the potential for NSSI to significantly increase the risk of later psychopathological symptoms and substance abuse problems. In addition, the significance of sex differences in risk factors for NSSI should be determined. This study evaluated how the impact of NLEs on NSSI can be reduced among adolescents from multiple perspectives. [ABSTRACT FROM AUTHOR]

Introduction: Non-suicidal self-injury (NSSI) is when a person harms themselves without the intention of suicide. The Emotional Cascade Model describes how NSSI could be a behavioral response to a cycle of negative affect and rumination, a form of repetitive negative thinking (RNT). However, there is limited research on other forms of RNT (i.e., anger rumination, sadness rumination, worry, catastrophizing) in relation to NSSI. Five Factor Model (FFM) domains and facets are predictive of NSSI history. However, continued research is warranted to assess reliability and generalizability of previous work. It was hypothesized that elevated neuroticism facets, elevated openness facets, lower levels of conscientiousness facets, and each type of RNT would predict a higher engagement in NSSI. Methods A community sample (N = 382) and college sample (N = 167) were tested with correlations and multiple regressions. Results Depressiveness and aesthetics positively predicted NSSI within the student sample. Impulsiveness and self-discipline positively predicted NSSI within the community sample. Worry positively predicted NSSI in both samples. Sadness rumination positively predicted NSSI and catastrophizing negatively predicted NSSI, but only within the student sample. Conclusion This study increased our understanding of precursors to NSSI, which could influence assessment and treatment. Continued research is warranted. [ABSTRACT FROM AUTHOR]

• This is one of the first studies examined differential pattern and risk factors of NSSI behavior of youth at different developmental stages during the COVID-19 pandemic in China. • The late-adolescent group (age ≥15 - <18) had the highest rate reporting NSSI behavior, while the young-adult group had the lowest rate during the COVID-19 pandemic. • Early-adolescents (age ≥12 - <15) with a poorer help-seeking pattern, lower paternal education level and being female had significantly higher rate of NSSI behavior. • Young adults (age ≥18 - ≤25) with increased smoking, higher maternal education level and lower education level had increased NSSI behaviors. • It is crucial to develop the targeted and personalized intervention strategies on reducing NSSI behavior for youth.

Background Method Results Conclusions Suicidal ideation and behavior and non‐suicidal self‐injury (NSSI) among Black emerging adults is a major public health concern. Intimate partner violence (IPV) is a significant risk factor for suicidal ideation and behavior and NSSI, but there is little work examining the buffering effect of psychological well‐being (PWB). The purpose of this study was to examine the associations between IPV, suicide ideation and behavior, and NSSI, and the moderating role of PWB on these associations.Secondary data analyses were conducted using a subsample of Black American emerging adults (N = 4694) from the National College Health Assessment.IPV was associated with greater odds of suicide ideation, past‐year suicide attempt, and NSSI. PWB was associated with lower odds of suicide ideation, past‐year suicide attempt, and NSSI. PWB did not moderate the relationships between IPV and the outcomes.IPV was a risk factor for suicidal ideation, suicide attempt, and NSSI among Black American emerging adults. PWB was associated with lower suicidal ideation and behavior and NSSI engagement, suggesting it can be a protective factor. Bolstering PWB in Black communities may be beneficial in intervention and prevention efforts. [ABSTRACT FROM AUTHOR]

Non-suicidal self-injury (NSSI) can both precede and co-occur with suicidal attempts (SA). Underlying mechanisms/factors leading to the transition to SA in NSSI youths have been proposed (including the role of social cognition), despite they should be yet confirmed. Therefore, the study aims at exploring the role of the Theory of Mind in the differentiation of a sample of NSSI youngsters (aged 15- 24) according to the presence of SA. We divided the sample into 4 groups using the Deliberate Self Harm Inventory (DSHI) and Columbia Suicide Severity Rating Scale (C-SSRS): control group (notNSSInotSA), NSSI without SA (NSSInotSA), NSSI with SA (NSSIplusSA), and SA without NSSI (SAonly). NSSIplusSA patients displayed higher Reading the Mind in the Eyes Test (RMET) scores (indicative of ToM abilities) than both the NSSInotSA (p=0.0016) and SAonly groups (p=0.0198), while SAonly patients showed lower RMET scores compared to the control group (p=0.0214). Multiple regression models used to differentiate NSSInotSA and NSSIplusSA found a significant association between RMET and LOSCS-CSC (Level Of Self-Criticism Scale-Comparative Self-Criticism) (pC=0.0802, pD=0.0016, pG=0.0053). Our findings supported the hypothesis that a hypertrophic affective ToM may possibly be associated with the occurrence of SA in youth NSSI. Further larger and longitudinal studies should confirm these preliminary findings, by exploring all social cognition dimensions. [ABSTRACT FROM AUTHOR]

The past two-and-half decades have produced a surge of research findings informing an abundance of patients displaying strong and frequent urges of self-harm (without suicidal ideation) but not fitting into any of the categorized psychiatric disorders (e.g., Borderline Personality Disorder-the most common disorder involving selfharm). Motivated by this we present a brief literature review of this confounding behavior known as Non-Suicidal Self Injury (NSSI). NSSI traditionally has been only a criterion of Borderline Personality Disorder (BPD). Findings in the last three decades however strongly suggest that (i) NSSI can often manifest in the absence of BPD, (ii) NSSI is best viewed as a transdiagnostic phenomenon due to its common co-occurrence with a variety of other psychological disorders (primarily depressive & anxiety disorders), and (iii) individuals indulging in NSSI (following the diagnosis criteria of DSM-5) generally tend to exhibit notably elevated levels of anxiety, depression and suicidal ideation compared to clinical control groups not practicing NSSI. While a multitude of factors have been investigated for their role as potential risk factors for NSSI, we found the inability to manage negative emotions (affect dysregulation) and prior history of NSSI to be most commonly reported. Childhood maltreatment (in its various forms), existing emotional disorders (mainly depressive & anxiety disorders), and cognitive variables like self-criticism and rumination are some of the other often-reported factors. We have also reviewed the various popular theoretical models of NSSI and found congruence between the core tenets of these models and empirical literature. [ABSTRACT FROM AUTHOR]

Background/Aims: Alexithymia is a concept characterized by the impairment of an individual's awareness of his feelings and ability to clearly identify and describe them. This study investigated whether alexithymia levels would differ in three different groups consisting of participants exhibiting suicidal ideation, attempted suicide, and non-suicidal self-injury (NSSI). Methods: Seventy-five patients admitted to the psychiatry clinic and emergency department due to suicidal ideation, attempted suicide, or non-suicidal self-injury and 25 healthy controls were included in the study. The Toronto Alexithymia Scale (TAS-20) and Hamilton Depression Rating Scale (HDRS) were applied to all participants. The individuals taking part were assigned into three different groups for comparisons: suicidal ideation, attempted suicide, and NSSI. Results: TAS-20 scores and HDRS scores were higher in the patient groups than in the healthy controls (p<0.001). Significantly higher TAS-20 scores were determined in the group with NSSI than in the attempted suicide group. Mean scores for the TAS subscales TAS-A (difficulty identifying feelings) and TAS-B (difficulty describing feelings) were significantly higher in the NSSI group than in the attempted suicide group. Positive correlation was found between severity of depression and alexithymia levels, TAS-20 scores, TAS-A scores, TAS-B scores, and TAS-C (externally oriented thinking) scores. Conclusion: The data from this study indicate that alexithymia levels in NSSI are higher than in individuals with attempted suicide and suicidal ideation. This finding reveals the importance of examining individuals with NSSI in terms of alexithymia as well. [ABSTRACT FROM AUTHOR]

Some researchers express caution about investigating potentially challenging topics in research, including trauma, non-suicidal self-injury (NSSI), and dissociation. While there have been studies that demonstrate people typically find participating in trauma- and NSSI-related research as more positive than negative, there have been no studies investigating how highly dissociative people react to trauma-, NSSI-, and dissociation-related research. Participants (n = 229) who self-reported dissociative symptoms and/or dissociative diagnoses completed an online survey about trauma, dissociation, and NSSI, followed by a quantitative questionnaire about their reactions to participation. Participants who endorsed unexpected emotional reactions were asked to explain their reactions and offer suggestions for improvement in a free-text qualitative question. Participants indicated the benefits of participating in the study outweighed the costs. Dissociation predicted emotional reactions but not other types of reactions (e.g. perceived drawbacks, personal benefits, global evaluation, and participation). However, when controlling for trauma history and NSSI, only trauma history predicted emotional reactions. Using codebook thematic analysis with the qualitative data, the following themes were developed to describe participants' unexpected emotional reactions and suggestions for improvement: (1) Trauma-Related Reactions (69.91%), (2) Neutral-Positive Feedback About the Study (39.82%), (3) Insight (24.78%), (4) Logistical Research Design Considerations (23.01%), and (5) Incongruence between Research Design and Lived Experience (11.50%). Research about trauma, dissociation, and NSSI was evaluated as more positive than negative and seemed to pose minimal risk to participants. It is important for researchers to not avoid studying these challenging topics yet strive to make their study design a safer and more validating experience for participants. [ABSTRACT FROM AUTHOR]

Previous research has linked self-harm to adverse childhood experiences (i.e. abuse and neglect). Despite the extensive literature on self-harm, it remains of high importance to examine psychological predictors of repetitive self-harming behaviors in those who report childhood trauma. This study explored the role of maladaptive emotion regulation strategies, dissociation proneness, and borderline personality (BP) features. An international sample with n = 374 participants (N = 287, 77%, reporting intentional use of self-harm), was recruited online via relevant mental health platforms and research sites. Within an anonymous survey, participants completed the Self-harm Inventory, Childhood Trauma Questionnaire, Dissociative Experience Scale, Cognitive Emotion Regulation Questionnaire, and Personality Assessment Inventory-Borderline Personality Features Scale. Structural equation modeling (SEM) was used to explore direct and indirect effects. Self-harm was positively correlated to severity of childhood trauma, maladaptive emotion regulation strategies, dissociation, and BP features. In the path-analytical model, independent indirect effects of childhood trauma severity via self-blame, catastrophizing, dissociation, as well as BP features on self-harm were found. Maladaptive emotion regulation, dissociation proneness, and BP features all seem to be important intermediary agents in the close association between childhood trauma and self-harm.

Introduction: Non‐suicidal self‐injury (NSSI) is a highly prevalent maladaptive behavior, often used to cope with intense negative affect. Rumination is an emotion regulation strategy that leads to fixation on and exacerbation of (typically) negative affective states. However, studies examining the relationship between rumination and NSSI have yielded mixed results, showing high degrees of heterogeneity. Methods: The present study conducted meta‐analyses (k = 50) of the association between overall rumination and NSSI, and independent meta‐analyses for each of four subtypes of rumination (general, depressive, brooding, reflection rumination). Potential moderators that may influence the magnitude of these relationships were also examined. Results: A small‐to‐moderate positive association between rumination and NSSI was found independent of rumination subtype. Moderating effects included NSSI outcome measure and study design for overall rumination and general rumination, respectively. Race was found to moderate the relationships between both brooding and depressive rumination and NSSI, though in inverse directions. An analysis of effect heterogeneity across studies suggested that undetected moderators may be present. Conclusion: Results of this study support the relationships between rumination subtypes and NSSI and identify factors that may impact these relationships. Continued research is needed to understand this association, particularly in more varied subtypes of rumination and cognitive‐affective moderators. [ABSTRACT FROM AUTHOR]

Non-Suicidal Self-Injury (NSSI) is associated with a heightened overall risk of future psychopathological problems. However, elucidating specific characteristics that determine an increased risk for certain individuals remains an area requiring further exploration. This study aimed to identify latent subgroups in a sample of college students with NSSI. Additionally, it sought to explore the differential associations of these subgroups with their psychopathological status (e.g., borderline symptoms and suicidal tendencies) both at baseline and after two years. The sample comprised 259 participants (89% females, Mage = 20.39, SD = 1.90) who reported engaging in NSSI in the last year. Three latent groups were found. The group exhibiting severe NSSI-features, high emotion dysregulation, and low perceived social support was the profile with high-risk of psychopathology both at baseline and follow-up. The findings enhance our understanding of the complex association between NSSI and future mental health issues, aiding in the early identification of at-risk individuals. [ABSTRACT FROM AUTHOR]

Background & Aims: Borderline personality disorder (BPD) is a common psychiatric disorder associated with a high risk of suicide attempts, death by suicide, and non‐suicidal self‐injury (NSSI). A systematic and comprehensive understanding of the link between BPD and suicide and self‐injury in adolescents and young adults is crucial for effective public health prevention strategies. This protocol outlines our approach to summarize the evidence on the association between BPD diagnosis and self‐injurious/suicidal behaviors including death by suicide, nonfatal suicide attempts, NSSI, and self‐harm behavior through a systematic review and meta‐analysis. Methods: The protocol is registered (PROSPERO: CRD42022363329) and developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses Protocols (PRISMA‐P)‐2015 statement. We will conduct a comprehensive literature search using electronic databases including MEDLINE, EMBASE, SCOPUS, Web of Science, CINHAL, and PsycINFO. The review will include studies that meet the specific inclusion criteria and will be searched using multiple databases A meta‐analysis will be conducted using a fixed‐effects or random‐effects approach based on the level of heterogeneity. Subgroup analysis and meta‐regression will be performed if necessary. Conclusion: This study is unique, as it is the first of its kind to systematically review and analyze the existing literature on this topic. The results of this study will provide important evidence on the magnitude of this relationship overall and in different subgroups, which can be used to inform the development of effective prevention and treatment strategies.

We aim to investigate the methylation of NR3C1 gene promotor and NR3C1 BclI polymorphism in schizophrenia (SCZ) patients with attempted suicide or non-suicidal self-injury (NSSI). A sample of 112 patients with SCZ was included in the study. Structured Clinical Interview for Diagnostic and Statistical Manual-Fourth Edition Axis I Disorders was used to confirm the diagnosis according to The Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision criteria. The patients were evaluated by data forms that had sociodemographic, suicidal behavior, and NSSI information. Methylation-specific polymerase chain reaction (PCR) was used to identify the methylation of the NR3C1 gene. The analysis of the BclI polymorphism of the NR3C1 gene was evaluated by using the PCR restriction fragment length polymorphism. Our results revealed that although the NR3C1 gene methylation was not statistically significantly different, there was a significant difference in NR3C1 genotype distribution among the SCZ groups with and without attempted suicide. SCZ patients carrying the CC genotype had a lower risk of attempted suicide (Odds Ratio [OR]: 0.421; 95% Confidence Interval [CI]: 0.183–0.970; p = 0.040), while having the GG genotype in SCZ patients was associated with a higher risk of attempted suicide (OR: 3.785; 95% Cl: 1.107–12.945; p = 0.042). Additionally, due to NSSI in SCZ patients, there were no significant differences in NR3C1 gene methylation and NR3C1 genotype distribution among the groups. We propose that the NR3C1 BclI polymorphism may be associated with attempted suicide in Turkish patients diagnosed with SCZ. [ABSTRACT FROM AUTHOR]

Background: Nurses face disproportionately high rates of suicidal ideation and non-suicidal self-injury (NSSI). The role of workplace violence, loneliness, and depressive symptoms in exacerbating these issues is poorly understood. This study aims to explore these relationships to inform interventions for improving nurses' mental health. Methods: A cross-sectional study involving 1,774 Chinese nurse staff selected through convenient sampling methods was conducted. Workplace violence, depressive symptoms, and loneliness were assessed using the Chinese versions of the Workplace Violence Scale (WVS), the 9-item Patient Health Questionnaire (PHQ-9), and a three-item loneliness scale, respectively. Participants completed self-report questionnaires anonymously to ensure adherence to ethical standards. Statistical analysis utilized structural equation modeling (SEM) to examine the intricate relationships among variables, thereby elucidating the impact of workplace violence, loneliness, and depressive symptoms on nurses' suicidal ideation/NSSI outcomes. Results: Nurse staff 165 (7.8%) were reported different level of suicidal ideation and 139 (7.8%) participants were reported different level of NSSI. And the final model of workplace violence on suicidal ideation shown a good model fit index (CMIN/DF = 3.482 NFI = 0.969 CFI = 0.977 TLI = 0.955 RFI = 0.938, RMSEA = 0.037 SRMR = 0.035). The pathway of workplace violence to loneliness (β = 0.163, P < 0.001), the indirect effect of workplace violence on suicidal ideation via loneliness and depressive symptoms were 0.100 (95%CI = 0.085, 0.121), the indirect effect of loneliness on suicidal ideation via depressive symptoms were 0.128 (95%CI = 0.100, 0.158). Similarly, the final model of workplace violence on NSSI shown a good model fit index (CMIN/DF = 3.482 NFI = 0.967 CFI = 0.976 TLI = 0.953 RFI = 0.935, RMSEA = 0.037 SRMR = 0.034), the pathways of workplace violence to NSSI (β = 0.115, P < 0.001), the indirect effect of workplace violence on NSSI via loneliness and depressive symptoms were 0.075 (95%CI = 0.055, 0.096), the indirect effect of loneliness on NSSI via depressive symptoms were 0.102 (95%CI = 0.076, 0.130). Conclusion: Our study unveils the role of workplace violence in nurses' suicidal ideation and NSSI, mediated by loneliness and depressive symptoms. Interventions targeting workplace violence are crucial for nurses' well-being, potentially reducing loneliness and depressive symptoms and lowering the risk of suicidal ideation and NSSI. However, further research is needed to explore additional mediators and pathways, employing longitudinal designs to establish causality and develop tailored interventions for nurses affected by workplace violence.

Background: Individuals may be more likely to engage in NSSI due to negative cognitive bias, while the use of negative emotional regulation mechanisms may further contribute to NSSI. Currently, there is a dearth of studies regarding the correlation among the three variables. Method: The study employed convenience sampling to collect data via online platforms from a total of 572 college students in Harbin, Heilongjiang Province, China, over the period of January 2024 to February 2024. The questionnaires comprise the Non-Adaptive Cognitive Emotion Srategy Regulation Subscale, the Negative Cognitive Processing Bias Questionnaire, and the NSSI Questionnaire. Outcome: Negative cognitive bias significantly and directly influences NSSI, as indicated by a beta coefficient of 0.3788 and a confidence interval of [0.2878, 0.4698]. The existence of negative cognitive bias significantly enhances the impact of non-adaptive cognitive emotion control approaches (β = 0.5613, CI [0.4808, 0.6418]). Non-adaptive cognitive emotion regulation strategies showed a significant effect on NSSI, as indicated by a beta coefficient of 0.2033 and a confidence interval of [0.0942, 0.3125]. The non-adaptive cognitive emotion control strategy serves as an intermediary between negative cognitive bias and NSSI, explaining 30.12% of the overall impact. In conclusion: The results demonstrate that non-adaptive cognitive emotion regulation strategies play a partially moderating role in the relationship between negative cognitive bias and NSSI among nursing students. We emphasize the importance of non-adaptive cognitive emotion regulation strategies, negative cognitive biases, and NSSI among nursing students. In order to reduce the occurrence of NSSI, it is important for schools, families, and teachers to work together closely and implement a well-organized and efficient intervention to protect the mental well-being of nursing students.

Background: Unhealthy lifestyle behaviors among adolescents have emerged as a significant public health concern worldwide, however, there is little investigation on the impact of unhealthy behaviors on non-suicidal self-injury (NSSI), suicidal ideation (SI) and suicide attempt (SA). This study aimed to investigate the prevalence of seven unhealthy behaviors as well as their associations with NSSI, SI and SA, and to explore whether the aforementioned associations differ across sex. Methods: A total of 74,152 adolescents were included in this study via a multi-stage, stratified cluster, random sampling method in 2021. Information about unhealthy behaviors (insufficient physical activity, current smoking, current drinking, excessive screen time, long homework time, insufficient sleep and unhealthy BMI), NSSI, SI, SA and other demographics was collected. Sampling weights were used to estimate the prevalence, and the weighted logistic regression models were performed. Stratified analyses by sex and sensitive analyses were conducted. Results: Overview, the weighted prevalence of adolescents had more than five unhealthy behaviors were 5.2%, with boys showing a higher prevalence than girls (6.5% vs.3.8%). Current smoking, current drinking, excessive screen use, long homework time, insufficient sleep, and unhealthy BMI were significantly associated with NSSI, SI and SA. Moreover, adolescents with high lifestyle risk scores were associated with an increased risk of NSSI (5–7 vs. 0: OR 6.38, 95% CI 5.24–7.77), SI (5–7 vs. 0: OR 7.67, 95% CI 6.35–9.25), and SA (5–7 vs. 0: OR 9.57, 95% CI 6.95–13.17). Significant sex differences were found in the associations of unhealthy behaviors with NSSI, SI and SA. Conclusion: Unhealthy behaviors are quite common among Chinese adolescents. Adolescents with multiple unhealthy behaviors are associated with increased risks of NSSI, SI, and SA. The implementation of school and family-based interventions to promote healthy lifestyles is recommended as a preventive measure against self-injurious behavior and suicidality in adolescents.

Introduction: Nonsuicidal-self-injury (NSSI)-related content recently emerged on social networking sites (SNS), despite its relationship with NSSI conducts is still unclear. Methods: Hence, the current population-based cross-sectional study investigated the interplay between SNS use, NSSI content engagement, risky social media challenges (RSMCs), in a sample of 404 young adults (aged 18--24), focusing on the influence of problematic social media use (PSMU) and fear of missing out (FoMO). Results: Around 51.5% of the samplewas engaged inNSSI-related contents on SNS, being mostly females (p<0.001), younger (p=0.005), transgender people and nonbinary people (p=0.030) and those who displayed higher PSMU (p<0.001) or FoMO (p=0.031). Around 66.2% of the sample currently practice NSSIs, predominantly among females (p<0.001), those using BeReal (p=0.012), actively looking for NSSIrelated contents on SNS (p<0.001) to be part of a group (p=0.0025) or learn how to practice NSSI (p=0.025). PSMU (p<0.001) and FoMO (p<0.001) emerged as significant predictors of NSSI content engagement, particularly among active seekers. NSSI conducts were significantly predicted by FoMO (p<0.001) and Snapchat (p=0.044), while negatively predicted by male sex (p<0.001), higher educational level (p=0.019) and age at which NSSI-related contents were firstly looked for (p=0.028). Discussion: These findings underline the need to implement preventivepolicies and targeted interventions to monitor NSSI-related contents on SNS, the impact of PSMU and FoMO on NSSI, particularly among youngsters.

Background: The prevalence of non-suicidal self-injury among South Korean adolescents has increased significantly, requiring academic attention. This methodological study aims to develop a non-suicidal self-injury motivation scale for adolescents and evaluate its validity and reliability. Methods: In the first phase of scale development, the factors constituting self-injury motivation were identified through a literature review and analysis of online counseling data from self-injuring adolescents. In the second phase, 45 initial preliminary items were derived based on the identified factors, and 38 preliminary items were selected through content validation by experts. In the scale validation phase, the survey was conducted using 38 items. Data were collected from adolescents with a history of self-injury, using exploratory factor analysis (EFA) involving 715 participants and confirmatory factor analysis (CFA) involving 537 participants. The EFA involved 27.0% male and 73.0% female participants, with a mean age of 16.83 years, and the CFA involved 20.7% male and 79.3% female participants, with a mean age of 16.15 years. The data collected were tested for validity and reliability using SPSS 28.0 and M-plus. Results: The EFA yielded four factors and 24 items. The factors were named interpersonal influence, emotion regulation, sensation seeking, and anti-suicide, and the scale had an explanatory power of 55.8%. In the CFA, the fit of the 23-item model after deleting one item with low standardized factor loadings was x2 = 1081.52 (p <.001), CFI = 0.829, RMSEA = 0.084, and SRMR = 0.075, confirming the acceptability of the self-injury motivation scale for adolescents. The scale evaluation results for convergent validity and discriminant validity met the criteria. The reliability test results showed that the overall reliability (Cronbach's α) was 0.88, and the reliability (Cronbach's α) of each factor was 0.89 for interpersonal influence, 0.83 for emotion regulation, 0.63 for sensation seeking, and 0.80 for anti-suicide, satisfying internal consistency. Conclusion: In this study, the self-injury motivation scale for adolescents in the community comprised four factors and 23 items. The scale can be used to examine self-injury motivation among adolescents in the community and to develop self-injury prevention intervention programs. [ABSTRACT FROM AUTHOR]

Theoretical models of non-suicidal self-injury (NSSI) have highlighted the complex interaction between underlying psychosocial vulnerabilities, but, there is limited empirical support for these conceptualizations. The aim of the study was to examine affective, cognitive and interpersonal factors predicting NSSI among emerging adults. A sample of 1,574 emerging adults aged 18–25 years, drawn from 19 colleges via multi-stage sampling completed measures of NSSI, emotion regulation, experiential avoidance, psychological distress, self-criticism, brooding-rumination, attachment style and perceived social support. The results indicated that 22.40% had engaged in one or more self-injuring behaviours in the past 12 months, with cutting skin, hitting self and severely scratching self as the most commonly endorsed methods. Exploratory structural equation modelling identified differential pathways to NSSI, with difficulties in regulating emotions emerging as the only direct predictor of NSSI. Two latent constructs reflecting relationally based affective and cognitive structures: a negative self-other representation, and attachment style of considering relationships as secondary to achievement were identified. These differentially, and indirectly impacted NSSI engagement through psychological distress and difficulties in emotion regulation. The implications for interventions to expand beyond addressing emotion regulation deficits, and include other affective, cognitive and relational vulnerabilities are discussed.

Introduction: Non-suicidal self-injury (NSSI), which refers to the deliberate act of causing harm to one's own body without the intent to commit suicide, occurs in 20% of youth. Interestingly, approximately 90% of individuals who engage in self-harm report intrusive mental imagery thereof shortly prior to the act of NSSI. Previous research has demonstrated that imagery rescripting (IR) is an effective technique to treat intrusive mental images and associated clinical symptoms, such as emotion dysregulation, in various psychiatric disorders. However, there is no research on IR for adolescents who self-harm. Therefore, the present study aims to investigate the efficacy and feasibility of a two-session short-intervention using IR to reduce NSSI and associated clinical symptoms in adolescents. The intervention was supported by an app-based digital health intervention (DHI). Methods: A single case series A-B design with three post-assessments (1 week, 1 month, and 3 months post-intervention) was implemented. Seven adolescents received two treatment sessions of IR, supported by a DHI between sessions. NSSI (SITBI), emotion regulation (ERQ), emotional distress (BDI-II, STAI-T), self-efficacy (WIRKALL_r), and treatment satisfaction (BIKEP) were evaluated. Results: There was an increase in adaptive emotion regulation strategies up to 3 months post-intervention. Furthermore, patients improved regarding their self-efficacy, depressiveness, anxiety, and NSSI symptomatology. The developed DHI was described as a helpful and supportive tool. Conclusion: The intervention has shown initial evidence to be feasible and beneficial for adolescents conducting NSSI. The DHI has demonstrated to be a valuable tool in the treatment of self-harming youth. [ABSTRACT FROM AUTHOR]

Background: Suicide among male construction workers are reported to be disproportionally high compared to the working age population. However, there is minimal understanding of the prevalence and associated factors for suicidal ideation, non-suicidal self-injury, and suicide attempt among this occupational group globally. Methods: A cross-sectional study was conducted on a large sample of male construction workers in Ireland (n = 1,585). We investigated the prevalence of suicidal ideation, non-suicidal self-injury and suicide attempts and sociodemographic, occupational, and mental health factors associated with these three outcomes. Multivariable Poisson regression was performed to estimate the prevalence rate ratio of suicidal ideation (model 1 primary outcome), while multivariable logistic regression was used to estimate the odds ratio of non-suicidal self-injury (model 2 primary outcome), and suicide attempt (model 3 primary outcome). Results: The lifetime prevalence rate for suicidal ideation was 22%, 6% for non-suicidal self-injury, and 6% for suicide attempt. In univariate modelling, socio-demographic and occupation-specific factors associated with the three outcomes included younger age (suicidal ideation and non-suicidal self-injury), not being in a relationship (suicide attempt) and working 35–44 h per week (suicidal ideation and suicide attempt). The mental health factors generalized anxiety disorder, depression, and suicide bereavement were significantly associated with increased risk of the three outcomes. In fully adjusted multivariable models, increasing severity of generalized anxiety disorder and depression were associated with an increased prevalence rate ratio of suicidal ideation, and a higher odds ratio of non-suicidal self-injury and suicide attempt. Conclusion: Suicidal ideation, non-suicidal self-injury and suicide attempt are significant issues for male construction workers that require specific attention. Findings highlight a need to support younger male construction workers and those bereaved by suicide. They also highlight the need for the early detection and treatment of generalized anxiety disorder and depression in order to intervene in, and potentially prevent, suicidality among male construction workers.

Aims Methods Results Conclusions We aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) and non‐suicidal self injury (NSSI) in adolescents with attention deficit hyperactivity disorder (ADHD).A semi‐structured psychiatric interview and an NSSI screening questionnaire were conducted. Questionnaires assessing CDS (with daydreamer, sleepy, and slow subdimensions), depression, anxiety, self‐esteem, emotion regulation, coping strategies, and loneliness were administered.Among 104 participants (n: 63, 60.6% girls), the combined type of ADHD was the most common (66.3%), and 35 adolescents (27 girls) were in the NSSI+ group. Although only depression and ADHD were found to be predictors of NSSI in ADHD, CDS was associated with many risk factors of NSSI in ADHD: depression, anxiety, emotion dysregulation, low self‐esteem, and emotion‐oriented coping ways. After controlling for the effects of cognitive problems/inattentiveness, depression, and anxiety, CDS still correlated with low self‐esteem and emotion dysregulation. The daydreamer and slow sub‐dimensions of CSD differed between NSSI+ and NSSI‐ groups, while sleepy did not.CDS is associated with several relevant factors, indirectly relating it to self‐harm in ADHD. CDS increases the vulnerability to mental health changes that could lead to NSSI in adolescence with ADHD. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of the present study was to examine the mediating role of emotion dysregulation on the association between attachment with parents and non-suicidal self-injury (NSSI) in Taiwanese undergraduates. Methods: A total of 399 university students from Taiwan (mean age = 20.35 years) completed online self-report measures assessing attachment with parents, emotion dysregulation and self-harming behaviors. Results: Structural equation modeling indicated that attachment with parents and emotion dysregulation each had a direct association with NSSI. Emotion dysregulation partially mediated the correlation between attachment with parents and NSSI among Taiwanese young adults. Seventy-two participants (18%) reported engaging in NSSI in the past year. Conclusions: The results indicate that NSSI is a prominent health concern among Taiwanese young adults. For young adults from Taiwan or East Asian cultures, targeting emotion dysregulation in NSSI prevention and intervention could be beneficial. [ABSTRACT FROM AUTHOR]

Background: Non‐suicidal self‐injury (NSSI) presents an increasingly prevalent problem for young people; however, there remains a scarce evidence base for effective, scalable treatments for adolescents. This study aimed to assess the feasibility and acceptability of a brief, cognitive analytic therapy (CAT)–informed intervention for young people who engage in NSSI (CATCH‐Y). Methods: A case series design recruited 13 young people who met the inclusion and exclusion criteria to participate in the five‐session intervention. Eligible participants were aged 13–17 years (M = 15.15, SD = 1.28) and had engaged in NSSI at least once in the previous 6 months. Feasibility and acceptability were measured via recruitment, retention, qualitative feedback and missing data. The secondary outcome measures of personal recovery and motivation were administered pre‐ and post‐assessment, with measures of depressive symptoms and urges to self‐injure. Results: The intervention was found to be largely feasible and acceptable with high rates of recruitment, retention and pre‐/post‐assessment data completeness. Measures showed preliminary support for positive change in rates of NSSI, urges to self‐harm, low mood and personal recovery, although results were mixed. Completion rates for remote assessments were low. Conclusions: The findings of this study support further evaluation of the CATCH‐Y intervention on a larger scale. In‐person assessments may be preferable to remote to ensure good completion rates. [ABSTRACT FROM AUTHOR]

Aims: Limited understanding exists regarding the neurobiological mechanisms underlying non‐suicidal self‐injury (NSSI) and suicide attempts (SA) in depressed adolescents. The maturation of brain network is crucial during adolescence, yet the abnormal alternations in depressed adolescents with NSSI or NSSI+SA remain poorly understood. Methods: Resting‐state functional magnetic resonance imaging data were collected from 114 depressed adolescents, classified into three groups: clinical control (non‐self‐harm), NSSI only, and NSSI+SA based on self‐harm history. The alternations of resting‐state functional connectivity (RSFC) were identified through support vector machine‐based classification. Results: Convergent alterations in NSSI and NSSI+SA predominantly centered on the inter‐network RSFC between the Limbic network and the three core neurocognitive networks (SalVAttn, Control, and Default networks). Divergent alterations in the NSSI+SA group primarily focused on the Visual, Limbic, and Subcortical networks. Additionally, the severity of depressive symptoms only showed a significant correlation with altered RSFCs between Limbic and DorsAttn or Visual networks, strengthening the fact that increased depression severity alone does not fully explain observed FC alternations in the NSSI+SA group. Conclusion: Convergent alterations suggest a shared neurobiological mechanism along the self‐destructiveness continuum. Divergent alterations may indicate biomarkers differentiating risk for SA, informing neurobiologically guided interventions. [ABSTRACT FROM AUTHOR]

Adolescent non-suicidal self-injury (NSSI) is a major public health issue. Family factors are significantly associated with NSSI in adolescents, while studies on forecasting NSSI at the family level are still limited. In addition to regression methods, machine learning (ML) techniques have been recommended to improve the accuracy of family-level risk prediction for NSSI. Using a dataset of 7967 students and their primary caregivers from a cross-sectional study, logistic regression model and random forest model were used to test the forecasting accuracy of NSSI predictions at the family level. Cross-validation was used to assess model prediction performance, including the area under the receiver operator curve (AUC), precision, Brier score, accuracy, sensitivity, specificity, positive predictive value and negative predictive value. The top three important family-related predictors within the random forest algorithm included family function (importance:42.66), family conflict (importance:42.18), and parental depression (importance:27.21). The most significant family-related risk predictors and protective predictors identified by the logistic regression model were family history of mental illness (OR:2.25) and help-seeking behaviors of mental distress from parents (OR:0.65), respectively. The AUCs of the two models, logistic regression and random forest, were 0.852 and 0.835, respectively. The key limitation is that this cross-sectional survey only enabled the authors to examine predictors that were considered to be proximal rather than distal. These findings highlight the significance of family-related factors in forecasting NSSI in adolescents. Combining both conventional statistical methods and ML methods to improve risk assessment of NSSI at the family level deserves attention. • The most important familial predictor within the random forest algorithm was family function. • The logistic regression model found family history of mental illness as the foremost familial risk predictor for NSSI. • Help-seeking behaviors of mental distress from parents or others in the family were protective predictors of NSSI. • Maternal education less than high school was a protective predictor of NSSI. • Both models resulted in an overall positive ability to predict family-related factors of NSSI.

Background: The present study aimed to investigate the potential role of perceived stress, impulsivity trait, executive dysfunction in non-suicidal self-injury (NSSI) thoughts among college students, as well as the gender differences. Methods: A sample of 890 university students completed self-report measures of NSSI thoughts in the past month, the level of perceived stress, impulsivity traits, and executive dysfunction. Results: Compared to those with low level of perceived stress, participants with high level of perceived stress reported significant higher levels of impulsivity trait and executive dysfunction, and higher frequency of NSSI thoughts, and there were no gender differences. Male participants with NSSI thoughts, compared to males without NSSI thoughts, reported significant higher levels of perceived stress and executive dysfunction. Female participants with NSSI thoughts, compared to females without NSSI thoughts, reported significant higher levels of perceived stress, impulsivity trait, and executive dysfunction. Hierarchical regression analysis revealed only executive dysfunction was associated with NSSI thoughts in males, while only perceived stress was associated with NSSI thoughts in females. Conclusion: This study revealed different influence factors for NSSI thoughts in male and female college students. NSSI thoughts in males were more likely associated with executive dysfunction while in females were due to recently perceived stress. [ABSTRACT FROM AUTHOR]

Abstract This study delves into the correlation between childhood trauma and non-suicidal self-injury (NSSI) behaviors among high school students. Additionally, it examines the mediating role of stress perception and the moderating role of the teacher-student relationship in this association. A questionnaire survey was administered to 1,329 high school students in Yunnan Province to assess childhood trauma, NSSI behaviors, and stress perception. Firstly, the survey revealed a 12% prevalence of NSSI, with girls exhibiting a higher occurrence compared to boys (OR = 0.413, 95% CI: 0.280–0.609). Secondly, childhood trauma emerged as a significant predictor of NSSI behavior, irrespective of gender or whether the individual was an only child (r = 0.17, P

Abstract Background Non-suicidal self-injury (NSSI) has exhibited an increasing trend in recent years and is now globally recognized as a major public health problem among adolescents and young adults. Negative life events (NLEs) are positively associated with NSSI. We sought to explore (1) whether sex plays a role in the risk of NLEs leading to NSSI and (2) the role played by mental health (MH). Methods We adopted a multi-stage cluster sampling method to select college students across four grades from May to June 2022. Generalized linear models were used to evaluate the relationships between NLEs, sex, MH and NSSI, presented as incidence-rate ratios (RRs) with 95% confidence intervals (CIs). We examined the complex relationship between these variables using the PROCESS method for moderation analysis. Results Following the exclusion of data that did not meet the study requirements, data from 3,578 students (mean age: 20.53 [± 1.65] years) were included. Poisson regression results indicate that high-level NLEs (RR = 0.110, 95%CI: 0.047–0.173) are associated with increased NSSI. Furthermore, interaction effects were observed among sex, NLEs and NSSI. MH and sex moderated the relationship between NLEs and NSSI. Conclusion Identifying risk factors for NSSI is also important when exploring the interaction between NLEs and MH given the potential for NSSI to significantly increase the risk of later psychopathological symptoms and substance abuse problems. In addition, the significance of sex differences in risk factors for NSSI should be determined. This study evaluated how the impact of NLEs on NSSI can be reduced among adolescents from multiple perspectives.

Adolescents with affective disorders were surveyed in representative samples drawn from three hospitals in Sichuan province, China. Data were obtained from 235 participants regarding their demographic characteristics, family characteristics, disease-related characteristics, and family functioning.Results: The study found family functioning and its’ dissatisfaction both lower than national norms from the perspectives of adolescents. Younger age, single-parent family, and reconstituted family were predictors of not close of cohesion. Younger age, lower educational level of father, and reconstituted family were associated with less change of flexibility. Less times of hospitalizations, higher educational level of father, stem family were more satisfy with cohesion. Higher educational level of father, and stem family were also associated with greater satisfaction with flexibility.Conclusion: The study demonstrated that the family function of adolescents of affective disorders was poor, more attention should be paid to it. Age, family structure, number of hospitalizations and the educational level of father were influencing factors of family functioning. Therefore, it is important for medical worker to assess demographic and family characteristics of adolescents with affective disorders. Younger children, children of reconstituted family and single-parent family, children with repeated hospitalizations and fathers of lower level of education should be given emphasized in implementation of interventions. Based on the evaluation results, personalized family therapy has been proved to be an affective measure and could be used in clinical work.Keywords: affective disorders, adolescent, family functioning

After using the propensity scoring method to exclude the influence of age between the two groups, it was found that patients with NSSI showed lower levels of Tbil (P=0.046) and UA (P=0.015) compared with those without NSSI. Logistic regression results showed that serum UA was associated with NSSI behavior in female patients (OR=0.995, 95% CI: 0.991– 0.999, P=0.014), and TSH was associated with NSSI in male participants (OR=0.499, 95% CI: 0.267– 0.932, P=0.029).Conclusion: Female and male may have different pathological mechanisms of NSSI. NSSI is more likely to be related to antioxidant reaction in female adolescent patients, while more likely to be related to thyroid function in male depressed adolescent patients.Keywords: antioxidant system, depressed adolescents, incidence, non-suicidal self-injury, thyroid function

Abstract Background Suicidal ideation (SI) is increasingly prevalent among adolescents, often arising from depression and linked with non-suicidal self-injury (NSSI). Previous studies have noted significant sex differences in the manifestation and predictors of SI, depression, and NSSI. Aim This study aims to analyze and compare the relationships between SI, depression, and NSSI among male and female adolescents, examining whether these associations differ based on sex. Methods A total of 368 adolescents (M = 15.43, SD = 1.22, about 56.2% female participants), both from clinical and school settings, were assessed for SI, depression, NSSI, and other related variables. Network analysis was utilized to explore the interconnections among these variables, focusing on identifying sex-specific patterns. Logistic regression was used to confirm the findings from the network analysis. Results The network analysis revealed significant sex differences in the relationships between SI, depression, and NSSI. In the female network, the edge weights between SI and NSSI (0.93) and between SI and depression (0.31) were much higher compared to the male network (0.29 and 0, respectively). Centrality indices (strength, betweenness, closeness, and expected influence) for SI, NSSI, and depression were also higher in the female network. Logistic regression confirmed these findings, with depression being a potential predictor of SI only in females (OR = 1.349, p = 0.001) and NSSI having a stronger influence on SI in females (OR = 13.673, p

Abstract Background Unhealthy lifestyle behaviors among adolescents have emerged as a significant public health concern worldwide, however, there is little investigation on the impact of unhealthy behaviors on non-suicidal self-injury (NSSI), suicidal ideation (SI) and suicide attempt (SA). This study aimed to investigate the prevalence of seven unhealthy behaviors as well as their associations with NSSI, SI and SA, and to explore whether the aforementioned associations differ across sex. Methods A total of 74,152 adolescents were included in this study via a multi-stage, stratified cluster, random sampling method in 2021. Information about unhealthy behaviors (insufficient physical activity, current smoking, current drinking, excessive screen time, long homework time, insufficient sleep and unhealthy BMI), NSSI, SI, SA and other demographics was collected. Sampling weights were used to estimate the prevalence, and the weighted logistic regression models were performed. Stratified analyses by sex and sensitive analyses were conducted. Results Overview, the weighted prevalence of adolescents had more than five unhealthy behaviors were 5.2%, with boys showing a higher prevalence than girls (6.5% vs.3.8%). Current smoking, current drinking, excessive screen use, long homework time, insufficient sleep, and unhealthy BMI were significantly associated with NSSI, SI and SA. Moreover, adolescents with high lifestyle risk scores were associated with an increased risk of NSSI (5–7 vs. 0: OR 6.38, 95% CI 5.24–7.77), SI (5–7 vs. 0: OR 7.67, 95% CI 6.35–9.25), and SA (5–7 vs. 0: OR 9.57, 95% CI 6.95–13.17). Significant sex differences were found in the associations of unhealthy behaviors with NSSI, SI and SA. Conclusion Unhealthy behaviors are quite common among Chinese adolescents. Adolescents with multiple unhealthy behaviors are associated with increased risks of NSSI, SI, and SA. The implementation of school and family-based interventions to promote healthy lifestyles is recommended as a preventive measure against self-injurious behavior and suicidality in adolescents.

Abstract Background Nurses face disproportionately high rates of suicidal ideation and non-suicidal self-injury (NSSI). The role of workplace violence, loneliness, and depressive symptoms in exacerbating these issues is poorly understood. This study aims to explore these relationships to inform interventions for improving nurses’ mental health. Methods A cross-sectional study involving 1,774 Chinese nurse staff selected through convenient sampling methods was conducted. Workplace violence, depressive symptoms, and loneliness were assessed using the Chinese versions of the Workplace Violence Scale (WVS), the 9-item Patient Health Questionnaire (PHQ-9), and a three-item loneliness scale, respectively. Participants completed self-report questionnaires anonymously to ensure adherence to ethical standards. Statistical analysis utilized structural equation modeling (SEM) to examine the intricate relationships among variables, thereby elucidating the impact of workplace violence, loneliness, and depressive symptoms on nurses’ suicidal ideation/NSSI outcomes. Results Nurse staff 165 (7.8%) were reported different level of suicidal ideation and 139 (7.8%) participants were reported different level of NSSI. And the final model of workplace violence on suicidal ideation shown a good model fit index (CMIN/DF = 3.482 NFI = 0.969 CFI = 0.977 TLI = 0.955 RFI = 0.938, RMSEA = 0.037 SRMR = 0.035).

Abstract Background Individuals may be more likely to engage in NSSI due to negative cognitive bias, while the use of negative emotional regulation mechanisms may further contribute to NSSI. Currently, there is a dearth of studies regarding the correlation among the three variables. Method The study employed convenience sampling to collect data via online platforms from a total of 572 college students in Harbin, Heilongjiang Province, China, over the period of January 2024 to February 2024. The questionnaires comprise the Non-Adaptive Cognitive Emotion Srategy Regulation Subscale, the Negative Cognitive Processing Bias Questionnaire, and the NSSI Questionnaire. Outcome Negative cognitive bias significantly and directly influences NSSI, as indicated by a beta coefficient of 0.3788 and a confidence interval of [0.2878, 0.4698]. The existence of negative cognitive bias significantly enhances the impact of non-adaptive cognitive emotion control approaches (β = 0.5613, CI [0.4808, 0.6418]). Non-adaptive cognitive emotion regulation strategies showed a significant effect on NSSI, as indicated by a beta coefficient of 0.2033 and a confidence interval of [0.0942, 0.3125]. The non-adaptive cognitive emotion control strategy serves as an intermediary between negative cognitive bias and NSSI, explaining 30.12% of the overall impact. In conclusion The results demonstrate that non-adaptive cognitive emotion regulation strategies play a partially moderating role in the relationship between negative cognitive bias and NSSI among nursing students. We emphasize the importance of non-adaptive cognitive emotion regulation strategies, negative cognitive biases, and NSSI among nursing students. In order to reduce the occurrence of NSSI, it is important for schools, families, and teachers to work together closely and implement a well-organized and efficient intervention to protect the mental well-being of nursing students.

Abstract Background The prevalence of non-suicidal self-injury among South Korean adolescents has increased significantly, requiring academic attention. This methodological study aims to develop a non-suicidal self-injury motivation scale for adolescents and evaluate its validity and reliability. Methods In the first phase of scale development, the factors constituting self-injury motivation were identified through a literature review and analysis of online counseling data from self-injuring adolescents. In the second phase, 45 initial preliminary items were derived based on the identified factors, and 38 preliminary items were selected through content validation by experts. In the scale validation phase, the survey was conducted using 38 items. Data were collected from adolescents with a history of self-injury, using exploratory factor analysis (EFA) involving 715 participants and confirmatory factor analysis (CFA) involving 537 participants. The EFA involved 27.0% male and 73.0% female participants, with a mean age of 16.83 years, and the CFA involved 20.7% male and 79.3% female participants, with a mean age of 16.15 years. The data collected were tested for validity and reliability using SPSS 28.0 and M-plus. Results The EFA yielded four factors and 24 items. The factors were named interpersonal influence, emotion regulation, sensation seeking, and anti-suicide, and the scale had an explanatory power of 55.8%. In the CFA, the fit of the 23-item model after deleting one item with low standardized factor loadings was x 2 = 1081.52 (p

Abstract Background Suicide among male construction workers are reported to be disproportionally high compared to the working age population. However, there is minimal understanding of the prevalence and associated factors for suicidal ideation, non-suicidal self-injury, and suicide attempt among this occupational group globally. Methods A cross-sectional study was conducted on a large sample of male construction workers in Ireland (n = 1,585). We investigated the prevalence of suicidal ideation, non-suicidal self-injury and suicide attempts and sociodemographic, occupational, and mental health factors associated with these three outcomes. Multivariable Poisson regression was performed to estimate the prevalence rate ratio of suicidal ideation (model 1 primary outcome), while multivariable logistic regression was used to estimate the odds ratio of non-suicidal self-injury (model 2 primary outcome), and suicide attempt (model 3 primary outcome). Results The lifetime prevalence rate for suicidal ideation was 22%, 6% for non-suicidal self-injury, and 6% for suicide attempt. In univariate modelling, socio-demographic and occupation-specific factors associated with the three outcomes included younger age (suicidal ideation and non-suicidal self-injury), not being in a relationship (suicide attempt) and working 35–44 h per week (suicidal ideation and suicide attempt). The mental health factors generalized anxiety disorder, depression, and suicide bereavement were significantly associated with increased risk of the three outcomes. In fully adjusted multivariable models, increasing severity of generalized anxiety disorder and depression were associated with an increased prevalence rate ratio of suicidal ideation, and a higher odds ratio of non-suicidal self-injury and suicide attempt. Conclusion Suicidal ideation, non-suicidal self-injury and suicide attempt are significant issues for male construction workers that require specific attention. Findings highlight a need to support younger male construction workers and those bereaved by suicide. They also highlight the need for the early detection and treatment of generalized anxiety disorder and depression in order to intervene in, and potentially prevent, suicidality among male construction workers.

Non-Suicidal Self-Injury (NSSI) is a growing phenomenon on social networks, with an estimated prevalence of 30% among young people in Spain. In light of the aforementioned considerations, we present a methodology designed to identify and analyse the content created by young people on TikTok. On the one hand, a quantitative study was conducted using an API to collect and classify multimedia content through hashtags. In addition, a qualitative analysis was conducted to elaborate a systemic study of the content. The objective is thus to identify the content on TikTok pertaining to NSSI and to comprehend their codes. [ABSTRACT FROM AUTHOR]

Childhood trauma was known to increase risks of social isolation, loneliness and self-injurious thoughts and behaviors in adulthood. The aim of this study was to examine the protect and risk factors of social health, self-injurious thoughts and behaviors between adults with or without childhood trauma. This was a cross-sectional study comprising of 145,043 participants enrolled in the UK Biobank. Childhood trauma was determined by the Childhood Trauma Screener. Social health included social isolation, loneliness and emotional support. Outcomes of self-injurious thoughts and behaviors included suicide ideation, suicide attempt and non-suicidal self-injury (NSSI). Demographic data, self-reported morbidities and other confounding variables were covariates. Stata 17.0 and SPSS 27.0 was used to analysis data. Compared with participants without childhood trauma, there was no protective effect of emotional support for NSSI in participants with childhood trauma (β -value difference = 0.334, p = 0.008). The risk effect of loneliness for suicide ideation, suicide attempt and NSSI were also weaker in participants experiencing childhood trauma (p <0.05). Social isolation was no longer a risk factor for NSSI in all participants, while loneliness remained as a threat (p < 0.05). Many variables were measured using core items of the scale in UK Biobank, meanwhile, the childhood trauma data collected in adulthood may have recall bias. Adults reported childhood trauma were less vulnerable to self-injurious thoughts and behaviors when experiencing loneliness, but they could also not be protected from NSSI through emotional support. Emotional dysregulation caused by childhood trauma may contribute to this. • Adults reported childhood trauma were less vulnerable to self-injurious thoughts and behaviors when experiencing loneliness; • Adults reported childhood trauma would not be protected from NSSI through emotional support. • Regardless of childhood trauma, social isolation was not a risk factor for NSSI, while loneliness remained as a threat.
