PURPOSE: To assess the utility of the Child Behavior Checklist (CBCL) to identify meaningful subtypes of emotional dysregulation in an outpatient pediatric psychiatry clinic. METHODS: The sample consisted of 417 newly referred youth 6–18 years of age. Parents completed the CBCL and rating scales measuring executive function deficits, social functioning, and quality of life. Patients were stratified into subtypes of emotional dysregulation and compared on clinical correlates based on the A-A-A profile consisting of the CBCL Anxious/Depressed, Aggressive Behavior, and Attention Problems (A-A-A) scales. RESULTS: 67% of youth had emotional dysregulation (CBCL A-A-A T-score ≥180) and of these, 39% had a positive CBCL-Bipolar (BP) profile (A-A-A T-score ≥210), 24% had depression without the BP profile (CBCL Anxious/Depressed and/or Withdrawn/Depressed T-scores ≥70 and A-A-A T-score ≥180 and

Bifactor models are a promising strategy to parse general from specific aspects of psychopathology in youth. Currently, there are multiple configurations of bifactor models originating from different theoretical and empirical perspectives. We aimed to test the reliability, validity, measurement invariance, and the correlation of different bifactor models of psychopathology using the Child Behavior Checklist (CBCL). We used data from the Reproducible Brain Charts (RBC) initiative (N = 7,011, ages 5 to 22 years, 40.2% females). Factor models were tested using the baseline data. To address our aim, we (a) searched for the published item-level bifactor models using the CBCL; (b) tested their global model fit; (c) calculated model-based reliability indices; (d) tested associations with symptoms' impact in everyday life; (e) tested measurement invariance across many characteristics, and (f) analyzed the observed factor correlation across the models. We found 11 bifactor models ranging from 39 to 116 items. Their global model fit was broadly similar. Factor determinacy and H index were acceptable for the p-factors, internalizing, externalizing, and somatic specific factors in most models. However, only the p- and attention factors predicted daily life symptoms' impact in all models. Models were broadly invariant across different characteristics. P-factors were highly correlated across models (r = .88 to .99) and homotypic specific factors were highly correlated. These results suggest that regardless of item selection and strategy to compose CBCL bifactor models, they assess very similar constructs. Taken together, our results support the robustness of the p-factor across distinct bifactor models and studies of distinct characteristics.

Background: Greater neuroticism has been associated with higher risk for Alzheimer’s disease (AD) dementia. However, the directionality of this association is unclear. We examined whether personality traits differ between cognitively-unimpaired carriers of autosomal-dominant AD (ADAD) and non-carriers, and are associated with in vivo AD pathology. Objective: To determine whether personality traits differ between cognitively unimpaired ADAD mutation carriers and non-carriers, and whether the traits are related to age and AD biomarkers. Methods: A total of 33 cognitively-unimpaired Presenilin-1 E280A mutation carriers and 41 non-carriers (ages 27–46) completed neuropsychological testing and the NEO Five-Factor Personality Inventory. A subsample (n = 46; 20 carriers) also underwent tau and amyloid PET imaging. Results: Carriers reported higher neuroticism relative to non-carriers, although this difference was not significant after controlling for sex. Neuroticism was positively correlated with entorhinal tau levels only in carriers, but not with amyloid levels. Conclusion: The finding of higher neuroticism in carriers and the association of this trait with tau pathology in preclinical stages of AD highlights the importance of including personality measures in the evaluation of individuals at increased risk for cognitive impairment and dementia. Further research is needed to characterize the mechanisms of these relationships.

Background Pelvic girdle pain (PGP) is a multifactorial condition with a partly unknown etiology. This condition can be mentally and physically compromising both during and after pregnancy. To provide all-around preventive measures to improve the recovery from PGP, it is a necessity for obstetricians and orthopaedists to develop predictive studies about the worse prognosis for this condition. Therefore, this study aims to determine whether personality traits can predict the consequences of long-term pregnancy-related PGP. Methods This was a prospective study conducted from January 2015 to August 2018. A total of 387 pregnant women were enrolled in this study. According to whether they had experienced PGP during the past 4 weeks, the subjects were classified into no PGP and PGP groups. Persistent PGP after the pregnancy was defined as a recurrent or continuous visual analog score (VAS) pain rating of ≥3 for more than 1 week. The Quick Big Five Personality Test (QBFPT) was used to assess personality traits. Data were obtained by mail or in the clinic. The authors collected data including age, BMI, educational level, annual household income, cesarean delivery, breastfeeding, unexpected sex of the baby, parity, sick leave, no or rare ability to take rest breaks at work, and PGP in the previous pregnancy. Results Of 387 included women, 264 subjects experienced PGP during the pregnancy with a mean age of 26.3 ± 4.5 years. A total of 80 of 264 (30.3%) women experienced persistent PGP after the pregnancy. Persistent PGP after the pregnancy was associated with higher levels of neuroticism (OR = 2.12, P = 0.001). Comparing women with persistent PGP, those who reported higher levels of extraversion and conscientiousness were more likely to recover from this condition (OR = 0.65, P = 0.001; OR = 0.78, P = 0.010, respectively). Besides, neuroticism was positively associated with higher pain scores (r = 0.52, P = 0.005). However, extraversion and conscientiousness domains showed negative correlations with pain score (r = − 0.48, P = 0.003; r = − 0.36, P = 0.001). Conclusions Personality traits were significantly associated with the outcomes of PGP.

Background Psychogenic nonepileptic seizures (PNES) are still poorly understood and difficult to treat. Attachment theory could add new aspects to the understanding of the multifactorial genesis and maintenance of PNES and the therapeutic needs of this patient group. Objective The aim of the present study is to systematically assess attachment in adult patients with PNES with a focus on the role of unresolved/disorganized attachment. Methods A cross-sectional design was chosen to compare patients with confirmed PNES (n = 44) and healthy controls (n = 44) matched for gender, age, and education. Attachment was assessed using the Adult Attachment Projective Picture System. Psychometric questionnaires included the Childhood Trauma Questionnaire; Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) axis II disorders, Patient Questionnaire; the Somatoform Dissociation Questionnaire; and the Patient Health Questionnaire. Results We found significantly less secure (P = 0.006) and more unresolved/disorganized (P = 0.041) attachment classifications in the PNES group. Among patients with PNES, 7% were classified secure and 43% were classified unresolved/disorganized. Patients with an unresolved attachment representation were significantly more likely to be screened positive for personality pathology in the Structured Clinical Interview for DSM-IV axis II disorders, Patient Questionnaire (P = 0.03) and to report more emotional abuse in the Childhood Trauma Questionnaire (P = 0.007) than patients with other attachment classifications. Conclusions Our findings suggest that unresolved/disorganized attachment might be the predominant attachment style in patients with PNES and might be associated with more severe personality pathology. This could be of therapeutic relevance. The present study is the first to assess adult attachment in patients with PNES using a semi-structured interview in comparison to matched healthy controls.

The Severity Indices of Personality Problems (SIPP; Verheul et al., 2008) is a popular self-report questionnaire that measures severity of maladaptive personality functioning. Two studies demonstrated the utility of the short form (SIPP-SF) among older adults but validation in clinical settings is lacking. Therefore, we examined the psychometric properties of the SIPP-SF in a large sample of older adult Dutch outpatients (N = 124; age range = 60-85 years, M = 69.8, SD = 5.3). The SIPP-SF domains showed good to excellent internal reliability (Cronbach's α = .75-.91) and effectively discriminated between participants with and without a personality disorder, as assessed with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). Convergent validity of the SIPP-SF was examined with instruments for measuring personality pathology among older adults (Informant Personality questionnaire [HAP]; Gerontological Personality Disorders Scale [GPS]). The GPS generally correlated with the SIPP-SF domains in expected directions, with small to large effect sizes. For the HAP, only 1 scale correlated with all SIPP-SF domains. No associations were found between the SIPP-SF and psychiatric symptomatology as measured by the Brief Symptom Inventory (BSI). The SIPP-SF appears to be a promising instrument for assessing maladaptive personality functioning among older adult outpatients.

Aim To investigate the psychological status of medical staff with medical device‐related nasal and facial pressure ulcers (MDR PUs) during the outbreak of COVID‐19, analyse the correlation between their psychological status and personality traits, so as to provide a reference for personalized psychological support. Design A total of 207 medical staff who were treating the COVID‐19 epidemic from Hunan and Hubei provinces were enrolled in this analytic questionnaire‐based study. Methods We used these measures: Eysenck Personality Questionnaire Short Scale (EPQ‐RSC), Social Appearance Anxiety Scale (SAAS), Positive and Negative Affect Scale (PANAS) and demographic information forms online. Results Medical staff wearing protective equipment are particularly susceptible to nasal and facial MDR PUs, which is increasing their social appearance anxiety; neuroticism is significantly related to social appearance anxiety and negative emotion. We should pay more attention to their psychological state, cultivate good personality characteristics and reduce negative emotions, and thereby alleviate their MDR PUs‐related appearance anxiety.

The endeavor to understand the human brain has seen more progress in the last few decades than in the previous two millennia. Still, our understanding of how the human brain relates to behavior in the real world and how this link is modulated by biological, social, and environmental factors is limited. To address this, we designed the Healthy Brain Study (HBS), an interdisciplinary, longitudinal, cohort study based on multidimensional, dynamic assessments in both the laboratory and the real world. Here, we describe the rationale and design of the currently ongoing HBS. The HBS is examining a population-based sample of 1,000 healthy participants (age 30–39) who are thoroughly studied across an entire year. Data are collected through cognitive, affective, behavioral, and physiological testing, neuroimaging, bio-sampling, questionnaires, ecological momentary assessment, and real-world assessments using wearable devices. These data will become an accessible resource for the scientific community enabling the next step in understanding the human brain and how it dynamically and individually operates in its bio-social context. An access procedure to the collected data and bio-samples is in place and published on https://www.healthybrainstudy.nl/en/data-and-methods/access.

Aims and objectives To explore the relationship between personality traits, caring characteristics and abuse tendency among professional caregivers of older people with dementia in long-term care facilities in China. Background Elder abuse is a serious global health problem and human right violation with high incidence among older people with dementia. There are many investigations about impact factors of risk of abuse among family caregivers of older people with dementia. However, in long-term care facilities, the situation of abuse tendency needs further investigation. Design Cross-sectional study. Methods An observational survey was conducted according to the STROBE checklist. We investigated 156 professional caregivers of older people with dementia in three long-term care facilities in Guangzhou, China. Participants completed a demographic questionnaire, the Caregiver Abuse Screen (CASE) and the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI). Data were analysed using Mann-Whitney U tests, Kruskal-Wallis tests, Spearman's rank correlation and logistic regression analyses. Results Over half of the participants (51.9%) reported abuse tendency to the older people with dementia. There was a significant negative correlation between the caregivers' agreeableness scores of NEO-FFI and their CASE scores. Multivariate logistic regression analyses highlighted that protective factors of abuse tendency were caregivers' agreeableness, care recipients' source of finances and their duration of dementia while higher care difficulty and presence of older people's behavioural and psychological symptoms of dementia (BPSD) were the risk factors. Conclusion Caregivers' agreeableness personality trait and the caring characteristics of older people with dementia may be relevant to abuse tendency in long-term care facilities. Further study with a larger sample size is needed to validate such a correlation. Relevance to clinical practice Older people with dementia are at high risk for abuse. Prospective caregivers could pay more attention to developing their own agreeableness. The managers might establish monitoring system for reducing the abuse.

To feel other’s pain would elicit empathy. Some theorists hypothesized that observing other’s pain may activate the primary emotion of maternal care instinct, which may function as a precursor of empathy. The maternal care instinct and empathy share the same genetic background and neuroendocrine underpinnings. An extensive body of research has shown that maternal behaviors relate to the oxytocinergic system, which has a strong influence on empathy. These studies suggest that the maternal care instinct may mediate the effect of oxytocin receptor gene (OXTR) on empathy. To provide evidence for this mediation, we used the subscale of CARE in Affective Neuroscience Personality Scales (ANPS) to measure the maternal care instinct and tested two OXTR single-nucleotide polymorphisms (SNPs), rs53576 and rs13316193, in 880 high school participants (588 females, 292 males; Mage = 16.51 years old, SD = 0.65). Results showed that the genotype of rs13316193 was indirectly associated with empathy via CARE, suggesting a mediating role of CARE in the pathway from OXTR to empathy. These findings may contribute to an understanding of how empathy emerges when one witnesses another person in pain.

Introduction Marijuana is one of the most widely used psychoactive substance. There is evidence of genetic predisposition for addiction. Objective The aim of the study is to evaluate personality traits measured by the NEO Five-Factor Inventory and State-Trait Anxiety Inventory, combined with analysis of Tag1B rs1079597 and Tag1D rs1800498 located in the DRD2 gene. Material and methods The study group consisted of 214 rural cannabinoid users and 301 controls. The same psychometric test and real-time PCR genotyping were performed in both studied groups. Results The values of Anxiety state, Anxiety trait, NEO FFI: Neuroticism and Openness in the rural cannabis using group were significantly higher than in the control group. On the other hand, lower values were observed among rural people using cannabis compared to the control group for NEO FFI: Extraversion, Agreeability and Conscientiousness. In the Anxiety trait subscale, a 2% association with the polymorphism DRD2 Tag1B rs1079597 was detected in subjects using cannabis. However, for the DRD2 Tag1D rs1800498, there was no effect on the differences in personality traits between rural cannabis users and the control group. Conclusions The study shows differences in personality traits between the cannabis using group and controls. Interaction between genetic factors and personality traits was also detected. The association showing the combination of psychological characteristics and genetic variants can bring us closer to the overall picture of the issue of marijuana addiction.

The Identity Disruption Model posits that negative early life experiences are associated with disrupted personal identity, which in turn increases the risk of internalizing societal standards of attractiveness and body dissatisfaction. Although internalization plays a central role in this model, it is unclear which aspect(s) of internalization (awareness, endorsement, or internalization) are most relevant to the Identity Disruption Model. To address this issue, female participants (N = 278) completed measures of the following constructs: early adversity; self-concept clarity; awareness, endorsement, and internalization of societal standards of attractiveness; and body dissatisfaction. Self-concept clarity was negatively correlated with internalization (r = -.45, p .001), but was not significantly correlated with awareness (r = -.05) or endorsement (r = -.11). Furthermore, structural equational modeling showed that there was a significant indirect path from early adversity to self-concept clarity to internalization to body dissatisfaction (unstandardized b = .015, SE

Background This study intended to examine the comprehensive clinical effects of school sandplay group counseling on the emotions and behaviors of children for the first time in Korea. Methods To this objective, 10 sessions of in-school sandplay group counseling were administered to 113 fourth- to sixth-graders in an elementary school located in Cheonan city for 12 weeks from March to July 2015. Each small group consisted of 10 to 16 children and the entire 12 sessions were composed of a baseline test, 10 therapy sessions, and a post-test and evaluation session. The study subjects consisted of 56 boys (49.6%) and 57 girls (50.4%). As the evaluation instruments, an epidemiologic questionnaire and the Korea Child & Youth Personality Test were used during the baseline phase and after the termination of the counseling. Results The comparison of the scores according to the KCYP clinical scales and detailed evaluation scales before and after the 12-week counseling showed an increase in the self-esteem and a significant decline in depression in the elementary students after the counseling. Conclusion It is deemed that school sandplay group counseling can help elementary school students to solve emotional problems and improve their self-esteem.

Background In the context of the COVID-19 pandemic, many individuals have been found to endorse conspiracy beliefs. Socio-demographic variables, personality functioning, anxiety, and loneliness could be risk factors for this endorsement. Methods In a representative sample of the German population (N = 2,503) measures of conspiracy mentality, conspiracy-related beliefs toward COVID-19, personality functioning (OPD-SQS), anxiety (HADS), and loneliness (UCLA) were assessed. Pearson product-moment correlations and multiple linear regression analyses were conducted. Results Conspiracy mentality and conspiracy-related beliefs toward COVID-19 were strongly correlated. Regression analyses found younger age, male gender, lower education, and lower income to be associated with conspiracy mentality. The subscales relationship model and self-perception of the OPD-SQS were positively related to conspiracy mentality whereas interpersonal contact was negatively associated. Higher levels of anxiety were statistically predictive for conspiracy mentality. Conclusion Our findings indicate a contribution of personality functioning to the understanding of conspiracy mentality and thus to the advancement of interventions during the pandemic.

The Effort-Expenditure for Rewards Task (EEfRT) has gained validity evidence from several studies. However, various modifications have been applied to the original version, which have never been compared systematically. In Study 1, we tested 120 healthy participants to directly compare two versions of the EEfRT. In Study 2, we tested a larger sample of 394 healthy participants to further examine the original EEfRT. We replicated the split-half reliability of both task versions. However, self-reported personality traits (e.g., trait BAS) correlated with only some task performance parameters in Study 1, which did not replicate for the original EEfRT in Study 2. Our results indicate complex and sometimes inconsistent relations between different personality traits, task properties, and reward attributes.

In this issue of Cancer Cell, Bagaev et al. discover conserved relationships between immune and stroma activity that are prognostic and predictive of response to immunotherapy across cancer types. The authors develop a visualization tool, akin to a tumor personality test, to integrate genomic and microenvironmental profiling and guide therapeutic decision-making.

Social dominance, the main organizing principle of social hierarchies, facilitates priority access to resources by dominant individuals. Throughout taxa, individuals are more likely to become dominant if they act first in social situations and acting fast may provide evolutionary advantage; yet whether fast decision-making is a behavioral predisposition of dominant persons outside of social contexts is not known. Following characterization of participants for social dominance motivation, we found that, indeed, men high in social dominance respond faster–without loss of accuracy–than those low in dominance across a variety of decision-making tasks. Both groups did not differ in a simple reaction task. Then, we selected a decision-making task and applied high-density electroencephalography (EEG) to assess temporal dynamics of brain activation through event related potentials. We found that promptness to respond in the choice task in dominant individuals is related to a strikingly amplified brain signal at approximately 240 ms post-stimulus presentation. Source imaging analyses identified higher activity in the left insula and in the cingulate, right inferior temporal and right angular gyri in high than in low dominance participants. Our findings suggest that promptness to respond in choice situations, regardless of social context, is a biomarker for social disposition.

Personality traits have been found to be related to a variety of health outcomes. The aim of this study was to examine how personality traits were associated with adjustment to the COVID pandemic in college students. The sample included 484 first-year university students (76% female) attending a northeastern university who completed the Big Five Inventory (BFI) personality assessment at the beginning of a semester that was disrupted by the COVID pandemic. Using a phone-based app, students completed daily ratings of mood, perceived stress levels, and engagement in a number of health promotion activities (exercise, mindfulness, adequate sleep, etc.) throughout the semester both before and after the onset of the pandemic (e.g., a within-person longitudinal design). Results, as expected, showed that mood and wellness indices generally declined during the COVID period, although stress levels actually decreased. Further, irrespective of COVID, improved mood, less perceived stress and greater participation in health promotion activities were significantly associated with a number of personality traits including neuroticism (lower), extraversion (higher), agreeableness (higher), and conscientiousness (higher). Of primary interest, mixed-effects models were used to test how major personality traits interacted with any changes in daily ratings from the pre-COVID to COVID period. Significant interactions terms were found suggesting differential impacts of the COVID epidemic for students with low versus high levels of particular traits. Higher levels of extraversion, for example, were found to be related to decreases in mood as the pandemic progressed in contrast to those with lower extraversion, for whom there was a slight increase in mood over time. These data support the conclusion that personality traits are related to mental health and can play a role in a person’s ability to cope with major stressful events. Different traits may also be more adaptive to different types of stressors.

Child birth is one of the most important events in a mother’s life. Different factors influence whether a child is delivered by cesarean or normal vaginal delivery. Despite the complications of cesarean, demand for this type of delivery is increasing. The purpose of this study was to examine the influence of personal traits on the choice of the delivery method based on HEXACO personality model. Two hundred and ten pregnant women in some health centers in Tehran volunteered to participate in this research. To identify their personality dimensions, the pregnant women first filled out HEXACO personality forms. Then, the received data were analyzed through multivariate analysis of variance using a software package called SPSS–23. 104 women selected cesarean and 106 other women preferred normal vaginal delivery. The results of the multivariate analysis of variance showed that there is a significant difference between the two groups of women for six personality factors in HEXACO (P = 0.001). The linear combination of personality characteristics of pregnant women has a significant effect on the choice of delivery method (P

Trait neuroticism refers to individual differences in negative emotional response to threat, frustration, or loss, operationally defined by elevated levels of irritability, anger, sadness, anxiety, worry, hostility, self-consciousness, and vulnerability to mental and physical difficulties. While functional studies have been fairly consistent when identifying regions associated with neuroticism during emotional stimuli, structural imagining studies do not tend to find a relationship between amygdala volume and trait neuroticism. There is a great deal of functional evidence that frontoparietal areas are related to the amygdala, and to emotional reactivity more generally, as a function of their involvement in emotion regulation. Specifically, top-down emotion appraisal and expression appear to involve parts of the dorsolateral and dorsomedial prefrontal cortices, which operate at least in part via the indirect modulation of the amygdala. It was hypothesized that cortical surface area and cortical thickness in regions associated with emotion appraisal/expression and emotional attention (i.e., superior frontal and rostral middle frontal gyri, respectively) would have an indirect effect on the relationship between amygdala volume and self-reported neuroticism (respectively), potentially explaining the inconsistency in the structural literature. In sample of 1106 adults, superior frontal and rostral middle frontal gyri, as parcellated by Freesurfer, were examined as potentially restricting variance in a model of indirect effects, which may elucidate the overall relationship between cortical and subcortical gray matter volume and trait neuroticism. Results indicated that, despite no association between bilateral amygdala volume and trait neuroticism, when right superior frontal surface area was entered into the model of indirect effects, a significant relationship between amygdala volume and trait neuroticism emerged. Two of the three remaining models indicated that cortical surface area had an indirect effect on the relationship between amygdala volume and trait neuroticism. These findings highlight the relationship between structural and functional neuroimaging studies. Specifically, the results indicate that when volume is related to behavior, individual differences in higher-order cortical regions, particularly surface area, may help to better understand the relationship between emotion and subcortical gray matter volume.

Personality traits, such as higher Neuroticism and lower Conscientiousness, are associated with risk of Alzheimer's disease and other dementias. A diagnosis of dementia relies, in part, on informant ratings of the individual's cognitive status. Here we examine whether self-reported personality traits are associated with four measures of informant-rated cognition up to a decade later. Participants from the Health and Retirement Study (N = 2,536) completed a five-factor model measure of personality in 2006 or 2008. Informants completed the 2016 Harmonized Cognitive Assessment Protocol (HCAP), which included ratings of the participant's current cognitive functioning and change in cognitive function over the last decade assessed with the IQCODE, Blessed, 1066, and CSID. Controlling for characteristics of the participant, informant, and their relationship, higher Neuroticism and lower Conscientiousness were associated consistently with worse informant-rated cognition. The association between Openness and better informant-rated cognition was due primarily to higher baseline cognitive function. Extraversion and Agreeableness were associated with better informant-rated cognition only among participants who were cognitively intact at follow-up. The present research suggests that knowledgeable informants are able to detect cognitive deficits associated with personality.

BackgroundSchizotypy, a putative schizophrenia endophenotype, has been associated with brain-structural variations partly overlapping with those in psychotic disorders. Variations in precuneus structure have been repeatedly reported, whereas the involvement of fronto-striatal networks – as in schizophrenia – is less clear. While shared genetic architecture is thought to increase vulnerability to environmental insults, beneficial factors like general intelligence might buffer their effect.MethodsTo further investigate the role of fronto-striatal networks in schizotypy, we examined the relationship of voxel- and surface-based brain morphometry and a measure of schizotypal traits (Schizotypal Personality Questionnaire, with subscores Cognitive-Perceptual, Interpersonal, Disorganised) in 115 healthy participants [54 female, mean age (s.d.) = 27.57(8.02)]. We tested intelligence (MWT-B) as a potential moderator.ResultsWe found a positive association of SPQ Cognitive-Perceptual with putamen volume (p = 0.040, FWE peak level-corrected), moderated by intelligence: with increasing IQ, the correlation of SPQ Cognitive-Perceptual and striatal volume decreased (p = 0.022). SPQ Disorganised was positively correlated with precentral volume (p = 0.013, FWE peak level-corrected). In an exploratory analysis (p < 0.001, uncorrected), SPQ total score was positively associated with gyrification in the precuneus and postcentral gyrus, and SPQ Disorganised was negatively associated with gyrification in the inferior frontal gyrus.ConclusionsOur findings support the role of fronto-striatal networks for schizotypal features in healthy individuals, and suggest that these are influenced by buffering factors like intelligence. We conclude that protective factors, like general cognitive capacity, might attenuate the psychosis risk associated with schizotypy. These results endorse the idea of a continuous nature of schizotypy, mirroring similar findings in schizophrenia.

Purpose Behavior studies have found that exercise addiction is associated with high impulsivity. In other addictions, neural mechanisms of impulsivity reflect abnormalities in the reward and inhibition systems. In this study, we determined whether abnormalities existed in the reward and inhibition systems of exercise addicts. Methods Three groups of male participants (15 exercise addicts, 18 regular exercisers, and 16 exercise avoiders) completed the Mini International Personality Item Pool (Mini-IPIP), the classic go/no-go task, and the exercise-related go/no-go task. Event-related potentials (ERP) were recorded during the go/no-go tasks, and correctly performed trials were analyzed. Results Exercise addicts scored lower for extraversion and higher for neuroticism, reflecting a poor capacity for emotional regulation and impulse control, and had larger N2 and P3d amplitudes during the exercise-related go/no-go task. Exercise addicts and exercise avoiders demonstrated impaired accuracy in the exercise-related go/no-go task and had larger N2 amplitudes compared with regular exercisers during the letter–digit go/no-go task. Exercise addicts and regular exercisers showed larger Go-N1 and Go-P2 amplitudes compared with exercise avoiders during the exercise-related go/no-go task. Exercisers (exercise addicts and regular exercisers) demonstrated higher activation in response to exercise-related stimuli as reflected by larger N1 and P2, and addicts (exercise addicts) demonstrated poorer inhibition as reflected by larger N2 and P3d amplitudes. Go-N1 and Go-P2 were significantly correlated with no-go accuracy in exercise-related task. Conclusions Exercise addicts scored higher for the neuroticism personality trait and exhibited overactivation of the reward system and underactivation of the inhibition system. Overactivation of the reward system may be related to long-term exposure to exercise. Underactivation of the inhibition system may be a crucial factor in exercise addiction.

The Schizotypal Personality Questionnaire (SPQ) is one of the most widely used screening tools for schizotypy in adults. The Schizotypal Personality Questionnaire-Child version (SPQ-C) was recently developed to assess schizotypy in children and has a similar three-factor structure to the adult SPQ (i.e., Cognitive-Perceptual, Interpersonal-Affective, and Disorganization). However, few studies to date have reported on the psychometric properties and the usefulness of the SPQ-C in Eastern populations, including Mainland China. This study presents the first psychometric assessment of the Chinese SPQ-C in Mainland China. Exploratory factor analysis and confirmatory factor analysis were used to assess the factor structure of the SPQ-C in 1668 children (M = 12.10, SD = 0.60 years) from the China Jintan Child Cohort Study. Our findings document a three-factor structure and partial measurement invariance across residential location and gender, replicating the psychometric properties of the SPQ-C in English. The Chinese SPQ-C further correlates with standard behavioral problems (i.e., Child Behavior Checklist, Youth Self-Report and Teacher Report Form), demonstrating construct validity and utility as a child psychopathology assessment tool. Our findings provide the first robust psychometric evidence for a three-factor structure of the Chinese SPQ-C in a large Mainland Chinese sample, and suggest that the SPQ-C is suitable as a screening tool for schizotypy in community children who may be at risk for behavioral problems and later psychosis.

OBJECTIVE AND METHOD Numerous risk factors for posttraumatic stress disorder (PTSD) have been identified; however, many do not inform treatment. Psychological inflexibility is a modifiable factor that can be targeted in psychological treatment. This study examined whether higher levels of psychological inflexibility predicted unique variance in PTSD symptom severity at 1-year follow-up in 236 U.S. veterans of the wars in Iraq in Afghanistan after accounting for the strongest known risk factors for PTSD. PTSD symptom severity was assessed using the Clinician Administered PTSD Scale. RESULTS In hierarchical regression analyses, higher baseline psychological inflexibility predicted unique variance in 1-year PTSD symptom severity (p < .001, medium effect) after accounting for the strongest predictors, including: serving in the Army, rank, trauma severity, perceived threat, peritraumatic dissociation, recent life stress, and social support. Psychological inflexibility remained a significant predictor of unique variance in 1-year PTSD symptom severity after accounting for all other predictors and personality factors (neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness; p < .001, small effect) and after accounting for all other predictors, personality factors, and baseline PTSD avoidance symptoms (p < .001; small effect). CONCLUSIONS Findings indicate a key unique association between psychological inflexibility and PTSD symptom severity over time that is not attributable to overlap with personality or PTSD avoidance symptoms. Additional research on psychological inflexibility in the development and maintenance of PTSD is warranted, as well as whether increasing psychological flexibility leads to reductions in PTSD symptoms and improved psychosocial functioning.

Objective:Loneliness and social isolation have negative health consequences and are associated with depression. Personality characteristics are important when studying persons at risk for loneliness and social isolation. The objective of this study was to clarify the association between personality factors, loneliness and social network, taking into account diagnosis of depression, partner status and gender.Design:Cross-sectional data of an ongoing prospective cohort study, the Netherlands Study of Depression in Older Persons (NESDO), were used.Setting and participants:474 participants were recruited from mental health care institutions and general practitioners in five different regions in the Netherlands.Measurements:NEO-Five Factor Inventory (NEO-FFI) personality factors and loneliness and social network were measured as well as possible confounders. Multinominal logistic regression analyses were performed to analyse the associations between NEO-FFI factors and loneliness and social network. Interaction terms were investigated for depression, partner status and gender.Results:Higher neuroticism and lower extraversion in women and lower agreeableness in both men and women were associated with loneliness but not with social network size irrespective of the presence of depression. In the non-depressed group only, lower openness was associated with loneliness. Interaction terms with partner status were not significant.Conclusions:Personality factors are associated with loneliness especially in women. In men lower agreeableness contributes to higher loneliness. In non-depressed men and women, lower openness is associated with loneliness. Personality factors are not associated with social network size.

Recent applications of item response tree models demonstrate that this model class is well suited to detect midpoint and extremity response style effects in both attitudinal and personality measurements. This paper proposes an extension of this approach that goes beyond measuring response styles and allows us to examine item-feature effects. In a reanalysis of three published data sets, it is shown that the proposed extension captures item-feature effects across affirmative and reverse-worded items in a psychological test. These effects are found to affect directional responses but not midpoint and extremity preferences. Moreover, accounting for item-feature effects substantially improves model fit and interpretation of the construct measurement. The proposed extension can be implemented readily with current software programs that facilitate maximum likelihood estimation of item response models with missing data.

Background In literature, there are many instruments for evaluating workaholism; however, they do not have convergent validity, because of the lack of a shared definition of workaholism. Objective We propose a new instrument for evaluating workaholism and work engagement, namely the Work-related Inventory (WI-10), which is based on Loscalzo and Giannini's (2017) comprehensive definition of workaholism. Methods We developed a pool of 36 items, covering: 1) addiction symptoms; 2) obsessive-compulsive symptoms, and 3) work engagement. Then, we conducted Exploratory and Confirmatory Factor analyses on a sample of 503 Italian workers (165 males, 337 females, one missing; Mean age = 38.26±10.84) aiming to reduce the number of items. Results The results showed a 10-items (2 filler) and 2-factor solution: 1) Workaholism and 2) Work Engagement; moreover, the WI-10 has good internal reliability, convergent and divergent validity. Conclusions We found good psychometric properties for the WI-10. We also proposed the cut-off scores for the screening of the four kinds of workers proposed by Loscalzo and Giannini (2017): disengaged workaholics, engaged workaholics, engaged workers, and detached workers. The WI-10 will be useful for both research and preventive and clinical purposes.

We used an experimental design to test the key concern that expressive empathy from evaluators during forensic interviews leads to more disclosure of misbehavior (e.g., stealing, breaking the law, manipulating others) from evaluees. In the context of a psychopathy assessment interview, evaluees (N = 94, 100% male, 57.4% Caucasian) interviewed by an evaluator using expressive empathy techniques were no more likely than those interviewed by an evaluator avoiding expressive empathy techniques to admit to past instances of misbehavior (d = .17, 95% CI [-.24, .57]). Instead, the use of expressive empathy techniques seemed to influence evaluator perceptions of the evaluees. Evaluators using expressive empathy rated evaluees as less psychopathic (d = -.52, 95% CI [-.93, -.11]), more conscientious (d = .72, 95% CI [.30, 1.13]), and as having engaged in less impression management (d = -.54, 95% CI [-.95, -.13]) than evaluators avoiding the use of expressive empathy. Put simply, when evaluators expressed empathy, it influenced the evaluator, not the evaluee. These findings suggest the need to expand professional discourse and research on empathy in forensic evaluations to better understand the possible effects of evaluator empathy on both evaluators and evaluees.

This study investigated if scores on tests of personal qualities are affected by whether they will determine selection decisions ("high stakes") or not; and whether they are stable for individuals and groups across a four-year medical course. Two tests, one assessing values and one assessing components of personality, were administered either at the same time as a medical university entrance exam (first cohort

The present study examined the factor structure and measurement invariance of the Behavioral Inhibition System/Behavioral Approach System (BIS/BAS) scales parent-report in children and adolescents ( N = 1,444, 58% girls) across age (Group 1, 2-5 years; Group 2, 6-9 years; Group 3, 10-13 years; Group 4, 14-18 years old) and gender. The results consistently underscored a four-factor structure, resembling the original factor structure, with one BIS-factor and three BAS-factors. Multigroup confirmatory factor analysis showed full measurement invariance across gender as well as across Group 1 and 2, and Group 2 and 3. Strong measurement invariance was found across Group 3 and 4, Group 1 and 3, and Group 2 and 4. Configural and metric invariance was found across Group 1 and 4. Hence, mean-level BIS/BAS scores can be compared across gender and age although comparison between preschool children (Group 1) and late secondary school children (Group 4) should be done with caution.

Background Identification of successful general surgical residents remains a challenging endeavor for program directors with a national attrition of approximately 20% per year. The Big 5 personality traits and the Grit Scale have been extensively studied in many industries, and certain traits are associated with professional or academic success. However, their utility in surgery resident selection is unknown. Methods We performed a retrospective review of all categorical surgery residents (n = 34) at the University of Texas Medical Branch from 2015 to 2017. Current residents were classified into low performing (n = 12) or non-low performing (n = 22) based on residency performance and standardized test scores. Groups were assessed for differences in both conventional metrics used for selection and Big 5 and grit scores using bivariate analysis and Pearson's correlation coefficient. Personality testing was administered to recent resident applicants (n = 81). Applicants were ranked using conventional application information. We then examined the applicants' personalities and their rank position with personality characteristics of non–low-performing residents to determine if there was any correlation. Results The Big 5 personality test identified significantly higher extroversion, conscientiousness, and emotional stability scores in those residents classified as non–low performers. There was no significant difference in conventional metrics or in grit scores between non–low performers and low performers. Our final rank does not correlate well with personality traits of non–low performers. Conclusions The Big 5 test may prove to be a useful adjunct to the traditional residency application in identifying applicants who may become successful in general surgery residency.

The 20-Item Toronto Alexithymia Scale (TAS-20) is the most widely used measure to assess the personality construct of alexithymia and is composed of three-factor analytically derived subscales. These subscales measure and represent three critical, theoretically based facets of alexithymia. The subscales are distinct, yet highly interrelated and only as a collective body do they reflect adequately the alexithymia construct. Although different studies using both university student and community samples suggest that TAS-20 total scores are largely reflective of variation on a single construct, and that subscale scores do not provide unique and reliable information beyond total scores, many users of the scale frequently continue to employ and even rely more heavily on subscale scores rather than total scale scores when interpreting research study outcomes. Our goal in this study is to provide clinicians and researchers with replicable psychometric information for the TAS-20 estimated from bifactor modeling in an attempt to provide further support for using total rather than subscale scores. In general, our findings were consistent with previous studies indicating that TAS-20 total scores can be considered indicative of a single construct. The replication of these earlier results from previous investigations provides additional support for the use of a total TAS-20 score and questions the utility of using TAS-20 subscale scores. Based on these results, we recommend that researchers and clinicians use a single total TAS-20 score and not subscale scores. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The International Classification of Diseases–11th revision (ICD-11) classification of personality disorders is the official diagnostic system that is used all over the world, and it has recently been renewed. However, as yet very few data are available on its performance. This study examines the Personality Inventory for ICD-11 (PiCD), which assesses the personality domains of the system, and the Standardized Assessment of Severity of Personality Disorder (SASPD), which determines severity. The Spanish versions of the questionnaires were administered to a community (n = 2,522) and a clinical sample (n = 797). Internal consistency was adequate in the PiCD (α =.75 to.84) but less so in the SASPD (α =.64 and.73). Factor analyses suggested a unidimensional or bidimensional structure for severity, while revealing that the personality trait qualifiers are organized into four factors: negative affectivity, detachment, dissociality, and a bipolar domain of disinhibition–anankastia. The mutual relationships between traits and severity were analyzed, as well as the ability of the whole system to identify clinical subjects. Although further improvements are required, the results generally support the use of the PiCD and the SASPD and help substantiate the new ICD-11 taxonomy that underlies them., This work was supported by project PI15/00536, part of the Plan Estatal de Investigación Científica y Técnica y de Innovación 2013-2016, financed by the ISCIII Subdirección General de Evaluación and the cofinanced by the European Regional Development Fund (ERDF, “A way to build Europe”; PI: F.

Personality tests employing comparative judgments have been proposed as an alternative to Likert-type rating scales. One of the main advantages of a comparative format is that it can reduce faking of responses in high-stakes situations. However, previous research has shown that it is highly difficult to obtain trait score estimates that are both faking resistant and sufficiently accurate for individual-level diagnostic decisions. With the goal of contributing to a solution, I study the information obtainable from comparative judgments analyzed by means of Thurstonian IRT models. First, I extend the mathematical theory of ordinal comparative judgments and corresponding models. Second, I provide optimal test designs for Thurstonian IRT models that maximize the accuracy of people’s trait score estimates from both frequentist and Bayesian statistical perspectives. Third, I derive analytic upper bounds for the accuracy of these trait estimates achievable through ordinal Thurstonian IRT models. Fourth, I perform numerical experiments that complement results obtained in earlier simulation studies. The combined analytical and numerical results suggest that it is indeed possible to design personality tests using comparative judgments that yield trait scores estimates sufficiently accurate for individual-level diagnostic decisions, while reducing faking in high-stakes situations. Recommendations for the practical application of comparative judgments for the measurement of personality, specifically in high-stakes situations, are given.

Despite the widespread use of the HEXACO model as a descriptive taxonomy of personality traits, there remains limited information on the test-retest reliability of commonly-used inventories to measure its traits. Studies typically report internal consistency estimates, such as alpha or omega, as measures of reliability, but there are good reasons to believe that these do not accurately assess reliability. Therefore, we report 12-day test-retest correlations of the 100- and 60-item English HEXACO-Personality Inventory-Revised (HEXACO-100 and HEXACO-60) domains, facets, and items. In order to test the validity of test-retest reliability, we then compare these estimates to correlations between self- and informant- reports (also known as cross-rater agreement), a widely-used validity criterion, as well as to domain and facet internal consistencies. Median estimates of test-retest reliability were .88, .81, and .65 (N = 416) for domains, facets, and items, respectively. Facets' and items' test-retest reliabilities were highly correlated with their cross-rater agreement estimates, whereas alphas were not. Overall, the HEXACO-Personality Inventory-Revised demonstrates test-retest reliability similar to other contemporary measures. We recommend that short-term retest reliability should be routinely calculated to assess reliability.

Body image concerns revolving around body ideals (thin ideal, muscular ideal) are widespread among women. Whereas a stronger preoccupation with ideal physical appearance is often assumed for narcissistic women, previous empirical findings have been mixed. Following a tripartite structure of 'agentic, antagonistic', and 'neurotic' narcissism facets, we reexamined whether trait narcissism predicted drive for 'thinness' and 'drive for muscularity'. We further explored the role of importance of appearance as a mediator and moderator of the relation between narcissism and body image concerns. Latent structural equation modeling was applied to self-report data from two independent nonclinical female samples (NSample1 = 224, NSample2 = 342). Results underlined the importance of distinguishing between narcissism facets: Neurotic (but not agentic or antagonistic) narcissism uniquely predicted drive for thinness and drive for muscularity. Importance of appearance mediated but did not robustly moderate these relations. Hence, neurotic narcissistic women (characterized by hypersensitivity, shame, and a fragile self-esteem) are particularly prone to body image concerns. This vulnerability seems partly driven by how much importance they ascribe to their appearance. Future work might build on these insights to further unravel the processes linking neurotic narcissism to body image concerns and how these can be targeted in practical interventions., Finanziert durch den Open-Access-Publikationsfonds der Westfälischen Wilhelms-Universität Münster (WWU Münster).

Individuals with Borderline Personality Disorder (BPD) or Social Anxiety Disorder (SAD) suffer from substantial interpersonal dysfunction and have difficulties establishing social bonds. A tendency to form negative first impressions of others could contribute to this by way of reducing approach behavior. We tested whether women with BPD or SAD would show negative impression formation compared to healthy women (HCs). We employed the Thin Slices paradigm and showed videos of 52 authentic target participants to 32 women with BPD, 29 women with SAD, and 37 HCs. We asked participants to evaluate whether different positive or negative adjectives described targets and expected BPD raters to provide the most negative ratings, followed by SAD and HC. BPD and SAD raters both agreed with negative adjectives more often than HCs (e.g., ‘Yes, the person is greedy’), and BPD raters rejected positive adjectives more often (e.g., ‘No, the person is not humble.’). However, BPD and SAD raters did not differ significantly from each other. Additionally, we used the novel process tracing method mouse-tracking to assess the cognitive conflict (via trajectory deviations) raters experienced during decision-making. We hypothesized that HCs would experience more conflict when making unfavorable (versus favorable) evaluations and that this pattern would flip in BPD and SAD. We quantified cognitive conflict via maximum absolute deviations (MADs) of the mouse-trajectories. As hypothesized, HCs showed more conflict when rejecting versus agreeing with positive adjectives. The pattern did not flip in BPD and SAD but was substantially reduced, such that BPD and SAD showed similar levels of conflict when rejecting and agreeing with positive adjectives. Contrary to the hypothesis for BPD and SAD, all three groups experienced substantial conflict when agreeing with negative adjectives. We discuss therapeutic implications of the combined choice and mouse-tracking results.

Background Social anxiety disorder (SAD) develops in the early teens and is a common disorder among university students. Understanding the predictive factors of SAD comorbid with major depressive episode (MDE) is important for student mental health care. The aim of this study was to identify the personality traits that predict SAD with MDE by analyzing longitudinal data of Japanese university students. Methods In this retrospective study, Japanese university students who visited the health care center of Hokkaido University for the first time were divided into the following four groups: “Control” (n = 43), “MDE” (n = 16), “SAD” (n = 28), and “SAD with MDE” (n = 61) based on the Patient Health Questionnaire-9 (PHQ-9), the Liebowitz Social Anxiety Scale, and core anxiety symptoms for SAD in the Mini International Neuropsychiatric Interview during screening. Predictors for SAD with MDE were identified by a four-group comparison of the Temperament and Character Inventory and PHQ-9 data previously obtained at the enrollment using analysis of variance and post-hoc tests. Results Upon comparing the four groups using analysis of variance, there were significant differences in the baseline PHQ-9 summary score, Harm-Avoidance (HA), and Self-Directedness (SD). According to results of the post-hoc test, all three showed a significant difference between the “Control” and “SAD with MDE.” Furthermore, there was a significant difference in HA scores between “SAD” and “Control.” In all the groups, the mean time from enrollment to the first visit to the center was >2 years. Conclusion A higher HA score at baseline is a predictor of SAD with or without MDE. Higher PHQ-9 summary and lower SD scores at baseline are predictive factors of SAD with MDE.
