Background: The hopelessness theory is one of the most studied cognitive vulnerability theories of depression. It proposes that risk for depression is conferred by attributing the causes of negative events to global, internal, stable causes and inferring future negative consequences and negative characteristics about oneself from these events. Nearly all research has operationalized cognitive style using individuals' responses to hypothetical events at single timepoints. Far less research has explored attributions of specific events as they occur, none of which has involved clinical samples.Methods: This study aimed to examine if measuring event-specific attributions clarifies the relationship between negative cognitive style and clinical symptoms. Adults (n = 51), who had attempted suicide at least once in the year prior, were recruited from the community via online forums related to suicide risk. Participants provided nightly ratings of hopelessness and attributions of the most stressful event that day for four weeks.Results: The daily diary composite measure of cognitive style was more strongly associated with hopelessness and depressive symptoms than the trait measure. Daily attributions fully mediated the relationship between trait cognitive style and hopelessness.Limitations: The measurement period could not capture the occurrence of a next depressive episode for all participants. Relatedly, we could not account for the precise nature of individual stressors.Conclusions: At a population level, trait measures alone may be a useful risk factor. But, with the goal to move towards more personalized prediction and intervention, more dynamic, ecologically valid, and real time measures may help gain more traction.

- Abstract
Despite copious data linking brain function with changes to social behavior and mental health, little is known about how puberty relates to brain functioning. We investigated the specificity of brain network connectivity associations with pubertal indices and age to inform neurodevelopmental models of adolescence. We examined how brain network connectivity during a peer evaluation fMRI task related to pubertal hormones (dehydroepiandrosterone and testosterone), pubertal timing and status, and age. Participants were 99 adolescents assigned female at birth aged 9–15 (M = 12.38, SD = 1.81) enriched for the presence of internalizing symptoms. Multivariate analysis revealed that within Salience, between Frontoparietal – Reward and Cinguloopercular – Reward network connectivity were associated with all measures of pubertal development and age. Specifically, Salience connectivity linked with age, pubertal hormones, and status, but not timing. In contrast, Frontoparietal – Reward connectivity was only associated with hormones. Finally, Cinguloopercular – Reward connectivity related to age and pubertal status, but not hormones or timing. These results provide evidence that the salience processing underlying peer evaluation is jointly influenced by various indices of puberty and age, while coordination between cognitive control and reward circuitry is related to pubertal hormones, pubertal status, and age in unique ways.

Each year in the United States, suicidal thoughts and behaviors lead to >15 million visits to emergency departments and stays in psychiatric inpatient units. We describe three key areas where advances are needed: (1) more accurate detection of patients at risk for suicide in hospital settings, (2) better use of time and resources with patients while in the hospital, and (3) identifying patients who are at the highest risk for suicide when their risk is at its highest. In this introduction to the special issue, we provide describe how the papers in this issue make needed advances regarding these three topics and outline directions for future suicide research in hospital settings.

- Abstract
Abstract Purpose Nonsuicidal self-injury (NSSI) is associated with increased risk of suicide attempts. Theories of NSSI assert interpersonal stress as a common risk factor for, and perhaps consequence of, NSSI. Prior research has not examined reciprocal associations between chronic interpersonal stress and NSSI. This study used a multiwave, prospective design to address this gap in a sample of adolescent girls, a group with elevated risk for both chronic interpersonal stress and NSSI. Pubertal development was examined as a moderator of the reciprocal associations. Methods Adolescent girls (N = 220; ages 12–16, M age = 14.69 years) at heightened risk for NSSI completed a baseline assessment and follow-up assessments over 18 months, divided into two 9-month epochs (Time 1 and 2). Pubertal development was assessed via self- and parent-report. Chronic interpersonal stress was assessed using a semistructured interview at the end of each time period. NSSI was measured using a semistructured clinical interview every 3 months within both time periods to enhance accurate reporting. Results Path models revealed that chronic romantic stress during Time 1, but not peer or parent–child stress, predicted NSSI during Time 2 among girls with more advanced pubertal development. Moreover, NSSI during Time 1 predicted higher levels of chronic romantic and parent–child stress during Time 2. Conclusions Results revealed a reciprocal relationship between chronic romantic stress and engagement in NSSI. Further, this association may be best understood in the context of pubertal development.

• People who self-injure experience more negative affective-cognitive states in daily life. • We found higher and more variable negative affect, rumination, and self-criticism. • We observed a negative affect–self-critical cascade in people who self-injure. • Enhancing positive affect may help buffer dysfunctional cognitions. • Baseline variables partially negated observed differences. Although the literature suggests trait-like differences in affective and cognitive vulnerabilities between individuals with and without a history of nonsuicidal self-injury (NSSI), little is known about how these dispositional differences are experienced in the natural environment. The present study compares the intensity, inertia, interaction, and variability of affective (negative and positive affect) and cognitive states (rumination, self-criticism) in the everyday lives of individuals who do and do not engage in NSSI. Using experience sampling methodology (ESM), 60 emerging adults (ages = 18–22 years) with and without past-year NSSI (equally distributed) completed eight questionnaires per day for 12 days (in total, 96 questionnaires per participant), resulting in 4,587 assessments (median compliance = 83.3%; IQR = 71.9–91.7). In a dynamic structural equation modeling framework, dynamic parameters (i.e., mean intensity, carryover effects, spillover effects, and within-person variability) were evaluated using multilevel vector autoregressive models. Emerging adults who engage in NSSI experience higher intensity and greater variability of negative affect, rumination, and self-criticism, whereas those who do not engage in NSSI experience higher intensity and lower variability of positive affect. In addition, past-year NSSI predicted stronger affective-cognitive interactions over time, with stronger spillover effects of negative and positive affect on subsequent rumination and self-criticism in individuals who engage in NSSI. Depressive symptoms and trait levels of emotion dysregulation and self-criticism partially negated these differences. Our findings provide evidence that emerging adults who self-injure experience more negative affective-cognitive states in daily life and point to the potential relevance of boosting positive emotions to buffer negative cognitions.

Aspirational Goal 3 of the National Action Alliance for Suicide Prevention's Research Prioritization Task Force is to predict who is at risk for attempting suicide in the near future. Despite decades of research devoted to the study of risk and protective factors for suicide and suicidal behavior, surprisingly little is known about the short-term prediction of these behaviors. In this paper, we propose several questions that, if answered, could improve the identification of short-term, or imminent, risk for suicidal behavior. First, what factors predict the transition from suicidal thoughts to attempts? Second, what factors are particularly strong predictors of making this transition over the next hours, days, or weeks? Third, what are the most important objective markers of short-term risk for suicidal behavior? And fourth, what method of combining information about risk and protective factors yields the best prediction? We propose that the next generation of research on the assessment and prediction of suicidal behavior should shift, from cross-sectional studies of bivariate risk and protective factors, to prospective studies aimed at identifying multivariate, short-term prediction indices, examining methods of synthesizing this information, and testing the ability to predict and prevent suicidal events.

Abstract: One of the most frequently reported, yet understudied, motivations for non-suicidal self-injury (NSSI) involves automatic positive reinforcement (APR), wherein sensations arising from NSSI reinforce and promote the behavior. The current study used experience sampling methodology with a clinical sample of self-injuring adolescents (N=30) over a 2-week period during which the adolescents reported NSSI behaviors, and rated if an APR motivation was present, and if so whether that motivation pertained to feeling “pain,” “stimulation,” or “satisfaction.” Over 50% of the sample reported at least one instance of NSSI for APR reasons. No significant differences were found on demographic factors or psychiatric comorbidity for those with and without an APR motivation. However, those with an APR motivation reported elevated NSSI thoughts, longer duration of those thoughts, and more NSSI behaviors. They also reported more alcohol use thoughts, alcohol use, impulsive spending, and binge eating. The most commonly reported sensation following NSSI for APR was “satisfaction.” However those endorsing feeling pain reported the most NSSI behaviors. These findings provide new information about the APR motivations for NSSI and shed light on the different sensations felt. [Copyright &y& Elsevier]

Abstract: This study applied a functional approach to the study of bingeing and purging behaviors. Based on a four-function theoretical model of bingeing and purging, it was hypothesized that these behaviors are performed because of their intrapersonally reinforcing (e.g., emotion regulation) and/or interpersonally reinforcing (e.g., help-seeking, attention-getting behavior) properties. Participants were 298 adult females who had engaged in bingeing or purging in the last 3 months and who provided data via an online survey of these behaviors. Confirmatory factor analyses revealed support for a four-function model of bingeing and purging in which people use these behaviors for intrapersonal reinforcement functions and also for interpersonal reinforcement. Understanding the functions of binge eating and purging has direct implications for assessment and treatment of these behaviors. [ABSTRACT FROM AUTHOR]

Abstract: Common clinical wisdom suggests that people who engage in self-injury are impulsive. However, virtually all prior work in this area has relied on individuals'' self-report of impulsiveness, despite evidence that people are limited in their ability to accurately report on cognitive processes that occur outside awareness. To address this knowledge gap, we used performance-based measures of several dimensions of impulsiveness to assess whether people engaging in non-suicidal self-injury (NSSI) demonstrate greater impulsiveness than non-injurers. In Study 1, we compared adolescent self-injurers (n =64) to age-, sex-, and race/ethnicity-matched, non-injurious controls (n =30) on self-reported impulsiveness (Schedule for Affective Disorders and Schizophrenia for School Age Children, Present and LifetimeVersion) and on performance-based measures of two dimensions ofi mpulsiveness: behavioral disinhibition (Conners'' Continuous Performance Test) and risky decision-making (Iowa Gambling Task). In Study 2, we compared adult female self-injurers (n =20) with age- and race/ethnicity-matched, non-injurious controls (n =20) on self-reported impulsiveness (Barratt Impulsiveness Scale-11), and performance-based measures of behavioral disinhibition, risky decision-making, and two measures of delay discounting. In both studies, self-injurers reported greater impulsiveness; however, performance-based measures of impulsiveness failed to detect any between-group differences. We propose several potential explanations for the discrepancies observed between self-report and performance-based measures of impulsiveness and discuss directions for future research on impulsiveness and self-injury.

Background: Intravenous ketamine has shown rapid antidepressant effects in early trials, making it a potentially attractive candidate for depressed patients at imminent risk of suicide. The Implicit Association Test (IAT), a performance-based measure of association between concepts, may have utility in suicide assessment. Methods: Twenty-six patients with treatment-resistant depression were assessed using the suicidality item of the Montgomery-Asberg Depression Rating Scale (MADRS-SI) 2 hours before and 24 hours following a single subanesthetic dose of intravenous ketamine. Ten patients also completed IATs assessing implicit suicidal associations at comparable time points. In a second study, nine patients received thrice-weekly ketamine infusions over a 12-day period. Results: Twenty-four hours after a single infusion, MADRS-SI scores were reduced on average by 2.08 points on a 0 to 6 scale (p < .001; d = 1.37), and 81% of patients received a rating of 0 or 1 postinfusion. Implicit suicidal associations were also reduced following ketamine (p = .003; d = 1.36), with reductions correlated across implicit and explicit measures. MADRS-SI reductions were sustained for 12 days by repeated-dose ketamine (p < .001; d = 2.42). Conclusions: These preliminary findings support the premise that ketamine has rapid beneficial effects on suicidal cognition and warrants further study. [Copyright &y& Elsevier]

The article examines the role played by emotional intelligence (EI) on the suicidal behavior of adolescents. It was found that EI is a protective factor for both suicidal ideation and attempts. The protective effect of emotional intelligence is driven by differences in strategic EI like having the ability to understand and manage emotions but not on experiential EI such as having the ability to perceive emotions and integrate them into thoughts. It is important to test the moderating influence of EI on a wider range of stressful life events and self-injurious behaviours.

Abstract: The question of why some people do things that are intentionally harmful to themselves continues to puzzle scientists, clinicians, and the public. Prior studies have demonstrated that one fairly extreme, direct form of self-harm, non-suicidal self-injury (NSSI), is maintained by both automatic (i.e., intrapersonal) as well as social (i.e., interpersonal) reinforcement. However, the majority of theoretical and empirical papers on this topic focus almost exclusively on the automatic functions. The purpose of this paper is to provide a more comprehensive analysis of the social functions of NSSI. Evidence is presented supporting the notion that NSSI is maintained by social reinforcement in at least a substantial minority of instances. Moreover, an elaborated theoretical model of the social functions of NSSI is outlined that proposes that this behavior represents a high intensity social signal used when less intense communication strategies fail (e.g., speaking, yelling, crying). The model further proposes that NSSI can serve not only as a signal of distress that is reinforced primarily by the caregiving behavior it elicits from others, but that it can also serve as a signal of strength and fitness that is reinforced by warding off potential threats (e.g., peer victimization), and in some cases can strengthen affiliation with others. Support for this theoretical model is drawn from diverse literatures including psychology, evolutionary biology, and cultural anthropology. The paper concludes with specific recommendations for empirical tests of the proposed model of the social functions of NSSI, as well as other harmful behaviors such as alcohol and drug use.

Prior research has examined the relations between various facets of emotion and psychopathology, with a great deal of recent work highlighting the importance of emotion regulation strategies. Much less attention has been given to the examination of emotion reactivity. This study reports on the development and evaluation of the Emotion Reactivity Scale (ERS), a 21-item self-report measure of emotion sensitivity, intensity, and persistence, among a sample of 87 adolescents and young adults. Factor analysis revealed a single factor of emotion reactivity best characterized the data. The ERS showed strong internal consistency (α = .94), convergent and divergent validity via relations with behavioral inhibition/activation and temperament, and criterion-related validity as measured by associations with specific types of psychopathology and self-injurious thoughts and behaviors (SITB). Moreover, emotion reactivity statistically mediated the relation between psychopathology and SITB. These findings provide preliminary support for the ERS and suggest that increased emotion reactivity may help explain the association between psychopathology and SITB. [ABSTRACT FROM AUTHOR]

Objective: This study examined the relationship between parental expressed emotion (EE) and adolescent self-injurious thoughts and behaviors (SITB), as well as potential mediators and moderators of this relationship.Method: Thirty-six adolescents ages 12 to 17 years recruited from the community (2004-2005) provided data. Parents of the adolescents completed the Five-Minute Speech Sample, a performance-based measure of EE, and adolescents completed interviews and rating scales assessing SITB, mental disorders, and related constructs.Results: Analyses revealed that high parental EE was associated with each type of SITB assessed: suicide ideation, suicide plans, suicide attempts, and non-suicidal self-injury. Analyses also revealed that one specific component of EE (i.e., parental criticism) was strongly associated with SITB, whereas the other (i.e., emotional overinvolvement) was not and that the relationship between EE and SITB was not explained by the presence of mental disorders. Finally, a moderation model was supported in which the relationship between parental criticism and SITB was especially strong among adolescents with a self-critical cognitive style.Conclusions: This study indicates that parental criticism is significantly associated with SITB and suggests one specific pathway through which the family may influence adolescent SITB. Future research is needed to replicate these findings and examine the direction of these relationships. [ABSTRACT FROM AUTHOR]- Published

Abstract: Non-suicidal self-injury (NSSI) is a prevalent behavioral problem, yet many fundamental aspects of NSSI remain unknown. This case series study reports on the diagnostic correlates of adolescents with a recent history of NSSI and examines the relation between NSSI and suicide attempts. Data are from clinical interviews with 89 adolescents admitted to an adolescent psychiatric inpatient unit who engaged in NSSI in the previous 12 months. Results revealed that 87.6% of adolescents engaging in NSSI met criteria for a DSM-IV Axis I diagnosis (M =3.0, S.D.=2.2, range=0 to 8 diagnoses), including externalizing (62.9%), internalizing (51.7%), and substance use (59.6%) disorders. Most adolescents assessed also met criteria for an Axis II personality disorder (67.3%). Overall, 70% of adolescents engaging in NSSI reported a lifetime suicide attempt and 55% reported multiple attempts. Characteristics of NSSI associated with making suicide attempts included a longer history of NSSI, use of a greater number of methods, and absence of physical pain during NSSI. These findings demonstrate the diagnostic heterogeneity of adolescents engaging in NSSI, highlight the significant overlap between NSSI and suicide attempts, and provide a point of departure for future research aimed at elucidating the relations between non-suicidal and suicidal self-injury.

Schools provide a useful, controlled setting for evaluating child behavior problems, yet direct observational coding procedures evaluated by child researchers have not been widely incorporated by practicing clinicians. This article provides a summary of procedures useful to clinicians performing direct behavioral observation in school settings. We describe the need for and usefulness of comprehensive school observations; provide a primer on the identification, definition, and assessment of target behaviors; and outline and discuss specific clinical procedures, including formulating primary referral questions, interviewing teachers, describing the classroom context, and conducting the observation. We also provide practical advice for synthesizing the obtained information into a report that guides clinical intervention. A sample of school observation coding forms and guidelines for report writing are also included to facilitate the use of these techniques by clinicians and teachers involved with the child.

Psychosocial treatment options are nearly as broad as the behavioral problems that they address. With literally hundreds of treatment approaches available, clinicians are confused as to how to select the most appropriate and effective intervention. One way is to consider using only those treatments with evidence of therapeutic efficacy. Indeed, funding agencies have invested substantial sums to evaluate the efficacy of many treatment, and the result is a growing list of evidence-based treatments (EBT) for children and adolescents. The accumulated data for these treatments support their consideration as first-line intervention options. Despite the documentation of the efficacy of these EBTs, they have not been widely incorporated by training programs or practicing clinicians.

PHOBIAS , *VOMITING - Abstract
A multiple-baseline design was used to evaluate the effectiveness of a behavioral treatment program using modeling, graduated exposure, and contingency management to treat food phobia in a 4-year-old boy. In addition, a treatment component involving time-out and re-introduction of the initial request to consume the target food was added to reduce vomiting behavior that developed during the course of treatment. The volume and range of foods consumed by the participant increased, and observer-rated anxiety and vomiting decreased over the course of treatment. The results of this controlled evaluation suggest that this treatment program was responsible for the observed changes, which were maintained at 6-month follow-up. [Copyright &y& Elsevier]

The article identifies the factors triggering the suicidal behavior among adolescents in the U.S. Results of a survey conducted on the behavior of adolescents in the nation reveal that suicide is the third leading cause of death among children and adolescents in the nation. Analysis on the possible factors that trigger suicide can be attributed to genetics, psychology and social relations. Potential factors that trigger suicide include bullying and victimization during childhood, conduct disorder and major depression.

The practice of therapeutic skills outside of sessions in which they are learned is one presumed key component of cognitive behavioral therapy (CBT). Yet, our understanding of how skills practice relates to clinical outcomes remains limited. Here, we explored patients' emotional responses to CBT skills practice in a pilot study pairing smartphone-app-delivered skills reminders and guided practice (ecological momentary intervention [EMI]) using ecological momentary assessment (EMA). Participants (n = 25) were adults recently hospitalized for a suicide attempt or severe suicidal thinking. They received brief inpatient CBT (1 to 3 sessions covering core CBT skills from the Unified Protocol), followed by 1 month of EMI and EMA after discharge. On average, participants reported modest reductions in negative affect after skills use (i.e., immediate responses; median time elapsed = 4.30 minutes). Additionally, participants tended to report less negative affect when the timepoint preceding the current assessment included EMI skills practice, rather than EMA alone (i.e., delayed responses; median time elapsed between prompts = 2.17 hours). Immediate effects were unrelated to longer-term clinical outcomes, whereas greater delayed effects were associated with lower symptom severity at follow-up. Future studies should further examine how CBT skills use in daily life may alleviate symptoms. [ABSTRACT FROM AUTHOR]

Globally, close to 800,000 individuals die by suicide each year. A scientific understanding of suicidal thoughts and behaviors have been slow to emerge owing to a number of challenges including low base rates, complexity and nonlinearity, low precision and accuracy of identification and detection methods, and variability across social and environmental contexts. To overcome these challenges, researchers have developed increasingly innovative and creative methods to overcome these challenges. These innovations hold considerable promise for advancing the science of suicide via large leaps forward rather than incremental steps. In this special issue of Behaviour Research and Therapy, we highlight several such efforts. [ABSTRACT FROM AUTHOR]

Suicide is a leading cause of death worldwide and perhaps the most puzzling and devastating of all human behaviors. Suicide research has primarily been guided by verbal theories containing vague constructs and poorly specified relationships. We propose two fundamental changes required to move toward a mechanistic understanding of suicide. First, we must formalize theories of suicide, expressing them as mathematical or computational models. Second, we must conduct rigorous descriptive research, prioritizing direct observation and precise measurement of suicidal thoughts and behaviors and of the factors posited to cause them. Together, theory formalization and rigorous descriptive research will facilitate abductive theory construction and strong theory testing, thereby improving the understanding and prevention of suicide and related behaviors. Due to scientific advances, there have been significant declines in many once-leading causes of death over the past 100 years, yet global suicide rates have remained fairly stable for decades. The lack of progress in understanding, predicting, and preventing suicide is due in part to the limitations of current scientific theories of suicide. After providing a brief history of suicide theories, we argue that these theories are limited due to two fundamental factors: (i) they are imprecise, comprising vaguely defined components and underspecified relationships among those components, precluding concrete theory predictions that could be tested; and (ii) there is a lack of rigorous descriptive research that is necessary to inform the generation, testing, and development of more precise theories. We provide several guiding principles to address these limitations, focusing on the need to formalize theories as mathematical and computational models and to collect rigorous and intensive descriptive research on key suicidal outcomes and the factors posited to give rise to those outcomes.

Background: People engage in nonsuicidal self-injury (NSSI) to reduce negative affect, but it is not clear why they engage in this harmful type of behavior instead of using healthier strategies. The primary goal of this study was to evaluate whether people choose NSSI to reduce negative affect because they perceive it to be less cognitively costly than other available strategies.Method: In experiment one, 43 adults completed a novel, relief-based effort discounting task designed to index preferences about exerting cognitive effort to achieve relief. In experiment two, 149 adults, 52 % with a history of NSSI, completed our effort discounting task.Results: Our main results suggest that people will accept less relief from an aversive experience if doing so requires expending less effort, i.e. they demonstrate effort discounting in the context of decisions about relief. We also found and that effort discounting is stronger among those with a history of NSSI, but this association became nonsignificant when simultaneously accounting for other conditions associated with aberrant effort tradeoffs.Limitations: The use of a control group without NSSI or other potentially harmful relief-seeking behaviors limits our ability to draw specific conclusions about NSSI. The ecological validity of our task was limited by a modestly effective affect manipulation, and because participants made hypothetical choices.Conclusions: This study demonstrates that preferences about exerting cognitive effort may be a barrier to using healthier affect regulation strategies. Further, the preference not to exert cognitive effort, though present in NSSI, is likely not unique to NSSI. Instead, effort discounting may be a transdiagnostic mechanism promoting an array of harmful relief-seeking behaviors. [ABSTRACT FROM AUTHOR]- Published

Suicide is among the most devastating problems facing clinicians, who currently have limited tools to predict and prevent suicidal behavior. Here we report on real-time, continuous smartphone and sensor data collected before, during, and after a suicide attempt made by a patient during a psychiatric inpatient hospitalization. We observed elevated and persistent sympathetic nervous system arousal and suicidal thinking leading up to the suicide attempt. This case provides the highest resolution data to date on the psychological, psychophysiological, and behavioral markers of imminent suicidal behavior and highlights new directions for prediction and prevention efforts.

SUICIDE risk factors , *SUICIDAL ideation , *ECOLOGICAL momentary assessments (Clinical psychology) , *STATISTICAL models , *SUICIDE - Abstract
Most theories of suicide propose within-person changes in psychological states cause suicidal thoughts/behaviors; however, most studies use between-person analyses. Thus, there are little empirical data exploring current theories in the way they are hypothesized to occur. We used a form of statistical modeling called group iterative multiple model estimation (GIMME) to explore one theory of suicide: The Interpersonal Theory of Suicide (IPTS). GIMME estimates personalized statistical models for each individual and associations shared across individuals. Data were from a real-time monitoring study of individuals with a history of suicidal thoughts/behavior (adult sample: participants = 111, observations = 25,242; adolescent sample: participants = 145, observations = 26,182). Across both samples, none of theorized IPTS effects (i.e., contemporaneous effect from hopeless to suicidal thinking) were shared at the group level. There was significant heterogeneity in the personalized models, suggesting there are different pathways through which different people come to experience suicidal thoughts/behaviors. These findings highlight the complexity of suicide risk and the need for more personalized approaches to assessment and prediction. • The generality of theorized risk factors for suicidal thinking across people is unknown due to lack of within-person data. • Ecological momentary assessment data was collected from adults and adolescents with suicidal thinking. • GIMME was applied to estimate statistical models for each individual and to identify associations shared across individuals. • There was heterogeneity in the models and results did not support the assumption that risk factors apply to all individuals.

Background: Depression and anxiety are both prevalent among university students. They frequently co-occur and share risk factors. Yet few studies have focused on identifying students at highest risk of first-onset and persistence of either of these conditions.Methods: Multicenter cohort study among Spanish first-year university students. At baseline, students were assessed for lifetime and 12-month Major Depressive Episode and/or Generalized Anxiety Disorder (MDE-GAD), other mental disorders, childhood-adolescent adversities, stressful life events, social support, socio-demographics, and psychological factors using web-based surveys; 12-month MDE-GAD was again assessed at 12-month follow-up.Results: A total of 1253 students participated in both surveys (59.2% of baseline respondents; mean age = 18.7 (SD = 1.3); 56.0% female). First-onset of MDE-GAD at follow-up was 13.3%. Also 46.7% of those with baseline MDE-GAD showed persistence at follow-up. Childhood/Adolescence emotional abuse or neglect (OR= 4.33), prior bipolar spectrum disorder (OR= 4.34), prior suicidal ideation (OR=4.85) and prior lifetime symptoms of MDE (ORs=2.33-3.63) and GAD (ORs=2.15-3.75) were strongest predictors of first-onset MDE-GAD. Prior suicidal ideation (OR=3.17) and prior lifetime GAD symptoms (ORs=2.38-4.02) were strongest predictors of MDE-GAD persistence. Multivariable predictions from baseline showed AUCs of 0.76 for first-onset and 0.81 for persistence. 74.9% of first-onset MDE-GAD cases occurred among 30% students with highest predicted risk at baseline.Limitations: Self-report data were used; external validation of the multivariable prediction models is needed.Conclusion: MDE-GAD among university students is frequent, suggesting the need to implement web-based screening at university entrance that identify those students with highest risk.

Abstract: Suicidal behavior is a prevalent problem among adolescents and young adults. Although most theoretical models of suicide suggest that this behavior results from the interaction of different risk factors, most prior studies have tested only bivariate associations between individual risk factors and suicidal behaviors. The current study was designed to address this limitation by testing the effect of an emotion–cognition interaction on suicide attempts among youth. Specifically, we hypothesized that the interaction of emotion reactivity and problem-solving skills would statistically predict the probability of a recent suicide attempt among 87 adolescents and young adults. Results revealed a significant interaction, such that emotion reactivity was strongly associated with the probability of a suicide attempt among those with poor problem-solving skills, moderately associated among those with average problem-solving skills, and not significantly associated among those with good problem-solving skills. The next generation of studies on suicidal behavior should continue to examine how risk factors interact to predict this dangerous outcome. [Copyright &y& Elsevier]

Background and Objectives: Individuals with disordered eating display heightened attentional biases towards food- and body-related stimuli. However, it is unknown whether these attentional biases reflect maladaptive thinking/eating pathology. We investigated the differences between maladaptive and adaptive ways of thinking about food by assessing food- and body-related attentional biases among individuals with disordered eating, participants with peanut allergies (i.e., individuals who think frequently about food in an adaptive manner), and healthy controls. We also examined the extent to which negative mood and rumination exacerbated attentional biases among those in these groups.Method: Three hundred and twenty-one individuals with disordered eating (n = 139), peanut allergies (n = 60), and healthy controls (n = 122) completed food- and body-based Stroop tasks prior to and following a cognitive rumination task designed to increase negative mood.Results: Individuals with disordered eating and individuals with peanut allergies had significantly worse performance on the food and body Stroop tasks relative to healthy controls at baseline (ps < .001). However, there were no perceived differences in performance by group following rumination.Limitations: The cognitive rumination task heightened negative mood for those in the disordered eating group but not for those in the peanut allergy or healthy control groups.Conclusions: Findings suggest that frequent thoughts involving food are associated with attentional biases towards food and body stimuli. This appears to be the case regardless of whether these frequent thoughts are due to disordered eating or to fear of an allergic reaction. [ABSTRACT FROM AUTHOR]- Published

Abstract: One of the leading biosocial theories of borderline personality disorder (BPD) suggests that individuals with BPD have biologically based abnormalities in emotion regulation contributing to more intense and rapid responses to emotional stimuli, in particular, invalidation [Linehan, M.M., 1993. Cognitive–Behavioral Treatment of Borderline Personality Disorder. Guilford, New York.]. This study used a 2 by 2 experimental design to test whether young women with features of BPD actually show increased physiological arousal in response to invalidation. Twenty-three women ages 18 to 29 who endorsed high levels of BPD symptoms and 18 healthy controls were randomly assigned to hear either a validating or invalidating comment during a frustrating task. Although we found preliminary support for differential response to these stimuli in self-report of valence, we found neither self-report nor physiological evidence of hyperarousal in the BPD features group, either at baseline or in response to invalidation. Interestingly, the BPD features group reported significantly lower comfort with emotion, and comfort was significantly associated with affective valence but not arousal. We discuss implications for understanding and responding to the affective intensity of this population. [Copyright &y& Elsevier]

Abstract: Background: We report prospective associations of baseline risk factors with the first onset and persistence of suicide-related outcomes (SROs; ideation, plans, gestures, and attempts) over a 10-year interval among respondents who participated in both the 1990–02 National Comorbidity Survey (NCS) and the 2000–02 National Comorbidity Survey follow-up (NCS-2). Methods: A total of 5001 NCS respondents were re-interviewed (87.6% of baseline sample) in the NCS-2. Three sets of baseline (NCS) risk factors were considered as predictors of the first onset and persistence of SROs: socio-demographics, lifetime DSM-III-R disorders, and SROs. Results: New onsets included 6.2% suicide ideation, 2.3% plan, 0.7% gesture, and 0.9% attempts. More than one-third of respondents with a baseline history of suicide ideation continued to have suicide ideation at some time over the intervening decade. Persistence was lower for other SROs. The strongest predictors of later SROs were baseline SROs. Prospective associations of baseline mental disorders with later SROs were largely limited to the onset and persistence of ideation. Limitations: Although data were gathered prospectively, they were based on retrospective reports at both baseline and follow-up. Conclusions: Baseline history of SROs explained much of the association of mental disorders with later SROs. It is important clinically to note that many of the risk factors known to predict onset of SROs also predict persistence of SROs. [Copyright &y& Elsevier]

Abstract: This study proposes and tests a theoretical model suggesting that the propensity to suppress unwanted thoughts is associated with an increased presence and frequency of self-injurious thoughts and behaviors (SITB). In the model, propensity to suppress unwanted thoughts is hypothesized to be a cognitive mediator of the relationship between emotional reactivity and SITB, and is expected to be related to the extent to which SITB is initiated to escape from aversive emotions. Results of this cross-sectional study of adolescents (N=87) revealed that the self-reported propensity to suppress unwanted thoughts is associated with the presence and frequency of non-suicidal self-injury (NSSI), suicidal ideation, and suicide attempts. Furthermore, thought suppression partially mediates the relationship between emotional reactivity and the frequency of NSSI and suicidal ideation. Finally, adolescents with a higher tendency to suppress unwanted thoughts report engaging in NSSI in order to reduce aversive emotions rather than for social communication. Results are discussed within the framework of the negative reinforcement function of SITB. [Copyright &y& Elsevier]

Despite functional models of nonsuicidal self-injury (NSSI) helping to explain why people engage in this perplexing behavior, we still lack an understanding of some of the key properties of NSSI functions. Here, we address three unanswered questions about NSSI functions: how much do distinct NSSI functions (1) vary between people over time, (2) vary within people over time, and (3) simultaneously co-occur over time? Data were drawn from three ecological momentary assessment (EMA) studies of self-injurious adult psychiatric outpatients (n = 7), community-based adolescents (n = 15), and community-based adults (n = 9). Across the three studies, there was a total of 271 NSSI episodes (all with corresponding functions captured by EMA). The vast majority (27 of 31; 87%) of participants exhibited unique patterns of NSSI functions during the monitoring periods, indicating high variability between people. The vast majority (26 of 31; 84%) of participants also showed changes in NSSI functions over time, indicating high variability within people. Although it was most common for only one function to be reported for a given NSSI episode, participants endorsed more than one function for 22% to 43% of NSSI episodes, indicating that different functions did simultaneously co-occur. These results underscore that reinforcement processes for NSSI differ from person-to-person, and are both time-varying and multifaceted, which has implications for personalized assessment and treatment of this clinical phenomenon.

Background: Suicidal and nonsuicidal self-injurious thoughts and behaviors (SITBs) are major health concerns among military veterans yet little is known about the temporal relations among these outcomes. This study examined the temporal relations between suicidal and nonsuicidal SITBs among higher-risk veterans. Specifically, we identified when SITBs emerged and evaluated the role of nonsuicidal self-injury (NSSI) in the medical lethality of suicide attempts (SA), relative risk, and survival time of suicidal SITBs (i.e., suicide ideation [SI], suicide plan, SA).Method: Cross-sectional data were collected from two samples examining suicide risk among veterans receiving inpatient psychiatric care (n = 157) and community-residing veterans with current depression and/or past month SI (n = 200). Participants completed an interview to assess SITBs.Results: SITBs emerged between ages 14-28 years with behaviors emerging, on average, earlier among inpatient veterans. The time lag between SITBs was not significantly different between groups. Inpatient veterans had a significantly shorter time lag from SI to SA. NSSI history predicted an increase in relative risk for all suicidal SITBs and shorter survival time. There was no association between NSSI history and medical lethality of the most serious SA for both groups.Limitations: Limitations included use of cross-sectional, retrospective self-report with age-of-onset endorsed in years and not all SITBs were assessed (e.g., passive SI).Conclusions: Veterans with a NSSI history are at high risk for suicidal SITBs and have a shorter survival time. Results showed thoughts (i.e., NSSI thoughts, SI) emerged before behavior (i.e., NSSI, SA) and NSSI emerged before SA. [ABSTRACT FROM AUTHOR]- Published

For over 100 years impulsiveness has been cited as a key factor in why some people that think about killing themselves go on to attempt suicide. Yet prior studies are limited by not using experimental groups that can test this hypothesis and by treating impulsiveness as a unidimensional construct. To overcome these limitations, we compared suicide ideators and suicide attempters on several dimensions of impulsiveness. In Study 1 we compared inpatient suicide attempters who made an attempt within the prior two weeks (n = 30), current inpatient suicide ideators (n = 31), and community controls (n = 34) on several dimensions of impulsiveness using self-report and behavioral measures. In Study 2 (n = 346), we compared three similar groups based on lifetime and past year suicidal behaviors on several of the measures in Study 1. In Study 1, we found only that negative urgency was clearly elevated among attempters compared with ideators. In Study 2, there were no significant differences on any impulsiveness constructs, including negative urgency. Results from the two studies suggest that attempters may not have significantly elevated trait impulsiveness, compared to ideators; however, attempters may have higher impulsiveness when in a negative state.

Deployment-related experiences might be risk factors for soldier suicides, in which case identification of vulnerable soldiers before deployment could inform preventive efforts. We investigated this possibility by using pre-deployment survey and administrative data in a sample of US Army soldiers to develop a risk model for suicide attempt (SA) during and shortly after deployment. Data came from the Army Study to Assess Risk and Resilience in Servicemembers Pre-Post Deployment Survey (PPDS). Soldiers completed a baseline survey shortly before deploying to Afghanistan in 2011–2012. Survey measures were used to predict SAs, defined using administrative and subsequent survey data, through 30 months after deployment. Models were built using penalized regression and ensemble machine learning methods. Significant pre-deployment risk factors were history of traumatic brain injury, 9 + mental health treatment visits in the 12 months before deployment, young age, female, previously married, and low relationship quality. Cross-validated AUC of the best penalized and ensemble models were.75–.77. 21.3–40.4% of SAs occurred among the 5–10% of soldiers with highest predicted risk and positive predictive value (PPV) among these high-risk soldiers was 4.4–5.7%. SA can be predicted significantly from pre-deployment data, but intervention planning needs to take PPV into consideration. [ABSTRACT FROM AUTHOR]

Early life adversity (ELA) characterized by threat (e.g., abuse, witnessing violence) impacts neural and physiologic systems involved in emotion reactivity; however, research on how threat exposure impacts the interplay between these systems is limited. This study investigates ELA characterized by threat as a potential moderator of the association between (a) neural activity during a negative image processing fMRI task and (b) cortisol production following a modified Trier Social Stress Test (TSST). The sample is comprised of 117 young adolescent females (M age = 11.90 years, SD = 1.69) at elevated risk for internalizing problems. Whole-brain analyses revealed a positive association between cortisol production and increased right lateral orbitofrontal cortex activity during the emotion reactivity task. In moderation models, threat exposure interacted with bilateral amygdala activation (b = −3.34, p = 0.021) and bilateral hippocampal activation (b = −4.14, p = 0.047) to predict cortisol response to the TSST. Specifically, participants with low, but not high, levels of threat exposure demonstrated a positive association between cortisol production and neural activity in these regions, while no significant association emerged for participants with high threat exposure. Findings contribute to the growing field of research connecting physiological and neural emotion processing and response systems, suggesting that dimensions of ELA may uniquely disrupt associations between neural activation and cortisol production. • Early life adversity (ELA) is associated with blunted cortisol secretion. • ELA-exposed individuals display amygdala hyperactivity and atypical hippocampal and vmPFC activation. • ELA characterized by threat moderates the association between cortisol secretion and amygdala and hippocampal activity.

Single-case experimental design (SCED) is a rigorous method of studying behavior and behavior change. A key characteristic of SCED is repeated, systematic assessment of outcome variables, which is critical to achieving high internal validity, collecting a sufficient number of observations to conduct adequately powered statistical analyses, capturing dynamic and fine-grained changes in outcomes, and tailoring interventions at the individual level. Recent advances in real-time monitoring technology, such as digital ecological momentary assessment, passive smartphone-based behavioral tracking, and physiological assessment with wearable biosensors, are extremely well-suited to conducting these repeated, systematic measurements. Here, we discuss the rationale for incorporating real-time data collection technologies within SCED and highlight how recent studies have paired SCED with real-time monitoring. We also present original data illustrating how real-time digital monitoring can provide an idiographic and granular view of behavior (in this case, suicidal ideation). Last, we discuss the challenges of, and offer our recommendations for, using real-time monitoring technologies in SCED research. • Real-time monitoring facilitates repeated, systematic assessment in SCED research. • We found only a small number of studies combining SCED and real-time monitoring. • Our data show how real-time monitoring can shed light on individual-level behavior. • We discuss challenges and recommendations for using real-time monitoring in SCED.
