Wall/Object Punching: An Important but Under-Recognized Form of Nonsuicidal Self-Injury

Examining the Presence, Frequency, and Associated Characteristics of Nonsuicidal Self-Injury by Proxy: Initial Validation of the Nonsuicidal Self-Injury by Proxy Questionnaire (NSSIBPQ)

Nonsuicidal self-injury (NSSI) by proxy is the intentional destruction of one's own body tissue through the elicitation of another being's actions. Despite its clinical relevance, research on NSSI by proxy is limited and there are no available measures of this behavior. This research aimed to characterize NSSI by proxy among young adults and provide preliminary data on the validity of a new self-report measure, the NSSI by Proxy Questionnaire (NSSIBPQ). Two nationwide community samples of young adults (one general community sample and one with a history of traditional NSSI and suicidality) completed online studies. NSSI by proxy was reported by 18% of the general community sample and 45% of the self-injuring sample. Findings support the clinical relevance of NSSI by proxy and its potential to meet criteria for an NSSI disorder diagnosis. Results also provide preliminary support for the internal consistency and convergent, discriminant, and concurrent validity of the NSSIBPQ.

Nonsuicidal self-injury characteristics: A mixed methods analysis of differences between veterans and civilians

Nonsuicidal self-injury (NSSI) is a well-established risk factor for suicidal behavior, with certain NSSI characteristics being associated with increased risk. In the United States (U.S.), the veteran suicide rate is elevated, though lifetime prevalence rates of NSSI appear similar between veterans and civilians. There is limited research that directly compares veterans and civilians across multiple NSSI characteristics to examine between-group differences in NSSI behavior and provide important context for the application of NSSI research with the veteran population. This study examined differences between U.S. veterans and civilians with a history of suicidal ideation across several NSSI characteristics, including method, severity, age of onset, shame, distress, and reason for initial NSSI engagement. A sample of 527 veterans and civilians completed measures of direct and indirect NSSI behaviors along with supplemental questions designed to further assess endorsed NSSI behaviors. Additionally, respondents provided written responses to an open-ended question about their reasons for initial engagement in NSSI, which were coded for post-hoc analysis. Chi-square difference tests and t-tests were conducted, revealing significant group differences between veterans and civilians in NSSI method, lifetime versatility, age of onset, age at last occurrence, and reasons for initial engagement. No significant differences were found in NSSI frequency, severity, shame, or distress. These findings provide valuable information on similarities and differences in NSSI behavior characteristics between U.S. veterans and civilians with lifetime suicidal ideation to inform future research and the assessment of NSSI in these populations.

The Prevalence of Nonsuicidal Self-Injury in Military Personnel: A Systematic Review and Meta-Analysis

Military service members and veterans (SMVs) are at risk for self-directed violence, including nonsuicidal self-injury (NSSI). While NSSI is an important construct worthy of independent study, it is understudied among SMVs and, when included in research, typically examined in the context of suicide risk. Consequently, lifetime prevalence rate estimates of NSSI among SMVs vary. This Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review and meta-analysis estimated the average lifetime NSSI prevalence among SMVs and explored demographic and methodological factors that may account for observed variability. Based on a search of Ovid MEDLINE, Embase, PsycINFO, and Web of Science, 47 samples from 42 articles across five countries met inclusion criteria. Results revealed an average NSSI lifetime prevalence rate of 15.76% among SMVs. Significantly higher prevalence rates were observed among clinical (28.14%) versus community (11.28%) samples and studies using interviews to assess NSSI (23.56%) versus self-report (13.44%) or chart review (7.84%). Lifetime prevalence increased as publication year increased and decreased as sample size increased. In contrast to prior literature, prevalence rates were comparable between active-duty SMVs, and studies collecting data anonymously versus those that did not. Lifetime prevalence was not moderated by age, gender, race, country, primary research focus, quality of NSSI operationalization, or whether NSSI methods were assessed. Findings suggest NSSI is a pervasive problem among military personnel, particularly within clinical settings, highlighting the need for systematic assessment of this important but understudied clinical phenomenon among SMVs. Further research is necessary to elucidate additional risk factors for NSSI among SMVs, including trauma exposure.

Nonsuicidal self-injury methods among U.S. Veterans: Latent class analysis and associations with psychosocial outcomes

Nonsuicidal self-injury (NSSI) is a debilitating concern among U.S. veterans, with wall/object-punching commonly endorsed as an NSSI method. We examined how this behavior relates to other NSSI methods and psychosocial outcomes. We conducted a latent class analysis (LCA) of NSSI methods among 1,138 Gulf War Era veterans, (77.9% male), 21.7% of whom endorsed lifetime NSSI. We categorized classes based on their associations with age, sex, combat and military sexual assault exposure, then examined the association of class membership with psychosocial indicators. LCA results supported four classes: 1) High punching/banging NSSI (2.5%); 2) Multimethod NSSI methods (6.3%); 3) High-risk, multimethod NSSI (3.1%); and 4) Low-risk NSSI (88.1%). Psychosocial indicators (suicide attempt, ideation, possible depressive or posttraumatic stress disorders, poor psychosocial functioning) were worse for members of the NSSI classes versus those in the low-risk group. A subset of U.S. veterans may engage in NSSI primarily via punching/banging methods. All patterns of NSSI engagement were associated with negative psychosocial outcomes relative to those in the low-risk class of the behavior.

The Effect of Gender on Identification and Interpretation of Non-Suicidal Self-Injury

INTRODUCTION

Reported rates of non-suicidal self-injury (NSSI) differ by gender but may be under-reported and under-recognised in men. People engaging in NSSI rarely seek professional help without encouragement, so others play a key role in its identification and potential intervention. The current research investigated others' interpretations of NSSI, examining whether gender affects the likelihood of NSSI identification and views of how common and acceptable NSSI is.

METHOD

Participants (N = 429; 74.1% female, 23.3% male; please see below for further demographic information) responded to two vignettes describing a person self-injuring by punching a wall or by cutting themselves. The person's gender in each vignette was manipulated. Following each vignette, the participants rated the level to which they agreed the behaviour was common for the gender of the person described, as well as the level to which they agreed the behaviour was acceptable for the gender of the person described, on a 5-point Likert scale. Following both vignettes, participants were presented with a definition of NSSI and rated the level to which they agreed cutting and wall-punching were forms of NSSI on 5-point Likert scales. Independent-samples t tests and goodness of fit χ2 tests were conducted as appropriate.

RESULTS

Participants were more likely to identify wall-punching as common for men and cutting as common for women. However, there was no significant difference in whether wall-punching was identified as NSSI or considered to be an acceptable behaviour, regardless of the gender of the person engaging in it. That is, although research suggests that men are far more likely to engage in wall-punching as a form of NSSI than women, participants did not recognise this. Overall, the results indicated a gender-dependent difference in how acceptable and common NSSI is thought to be, but no noticeable difference in identification of a behaviour as NSSI. Wall-punching, typically a form of NSSI engaged in by males, tended not to be identified as such.

CONCLUSION

There is an effect of gender on how NSSI is interpreted, and it seems that men's NSSI is, and will continue to be, under-recognised. This has important implications for the treatment of men's NSSI, which is more likely to be seen as aggression and therefore deserving of punishment than an attempt at emotion regulation.

Interpersonal stress and nonsuicidal self-injury disorder in veterans: An ecological momentary assessment study

INTRO

Nonsuicidal self-injury (NSSI) is associated with marked functional impairment and is a robust predictor of suicide attempts. Prevalence rates of NSSI, and self-directed violence more broadly, are elevated among military veterans. Despite the inclusion of interpersonal difficulty in the diagnostic criteria for NSSI disorder, the relationship between interpersonal risk factors and NSSI is not well-characterized, especially among veterans. This ecological momentary assessment (EMA) study investigated the hypothesis that interpersonal stressors and associated distress would precede and predict NSSI urge and engagement-but not vice versa-via cross-lagged multilevel modeling.

METHOD

Forty veterans with NSSI disorder completed a 28-day EMA protocol with three daily prompts assessing NSSI urges, NSSI engagement, the occurrence of interpersonal stressors, and associated subjective interpersonal distress.

RESULTS

Interpersonal stressors preceded and predicted subsequent NSSI urges, but not NSSI engagement, whereas subjective interpersonal distress preceded and predicted both NSSI urges and NSSI engagement.

CONCLUSION

Results identified interpersonal stressors as a risk factor for NSSI urges, and interpersonal distress as a risk factor for both NSSI urges and NSSI engagement. Findings highlight the importance of temporally assessing interpersonal factors related to NSSI and suggest that interpersonal distress may be a modifiable risk factor for NSSI.

Nonsuicidal self-injury among veterans is associated with psychosocial impairment, suicidal thoughts and behaviors, and underutilization of mental health services

Nonsuicidal self-injury (NSSI) is a robust predictor of suicide attempts. However, understanding of NSSI and associated treatment utilization among Veterans is limited. Although impairment may be assumed, few studies examine the association between NSSI and psychosocial functioning, a core component of the rehabilitation framework of mental health. In a national survey of Veterans, current NSSI (n = 88) was associated with higher rates of suicidal thoughts and behaviors and more severe psychosocial impairment after adjusting for demographics and probable diagnoses of posttraumatic stress disorder, major depressive disorder, and alcohol use disorder, compared to Veterans without NSSI (n = 979). Only half of Veterans with NSSI were engaged with mental health services, with few appointments attended, suggesting that these Veterans are not receiving treatment interventions. Results underscore the adverse outcomes associated with NSSI. Underutilization of mental health services highlights the importance of screening for NSSI among Veterans to improve psychosocial outcomes.

Experiential Avoidance, Posttraumatic Stress Disorder, and Self-Injurious Thoughts and Behaviors: A Moderation Analysis in a National Veteran Sample

Experiential avoidance (EA) is associated with posttraumatic stress disorder (PTSD) and self-injurious thoughts and behaviors (SITBs) across different populations, and extant literature has demonstrated a strong relationship between PTSD and SITBs. However, no study has explored the potential moderating role EA plays in the association of PTSD with nonsuicidal self-injury (NSSI), suicidal ideation, and suicide attempts. The objective of the present study was to determine if EA would moderate the association with PTSD and SITBs such that the association between PTSD and individuals SITBs would be stronger among individuals with higher EA. In a large national sample of Gulf War Era veterans (N = 1,138), EA was associated with PTSD, lifetime and past-year NSSI, current suicidal ideation, and lifetime suicide attempts in bivariate analyses. Multivariate analyses detected a significant EA by PTSD interaction on lifetime NSSI (AOR = 0.96), past-year NSSI (AOR = 1.03), and suicide attempts (AOR =1.03). Probing of the interactions revealed that the respective associations between PTSD, lifetime and past-year NSSI, and suicide attempts were stronger at lower levels of EA (i.e., better), counter to our hypotheses. These preliminary findings contextualize the relationship between these variables in a Gulf War veterans sample and signal the need to further investigate these relationships. Further, these findings highlight the need for advancement in assessment and intervention of EA and SITBs.

Traditional Masculine Gender Role Norms and Nonsuicidal Self-Injury in Veterans

Reducing Veteran rates of suicide has long remained a top priority for the Veterans Health Administration, and as such, identifying correlates of suicidal behaviors is important to develop targeted interventions. Nonsuicidal self-injury (NSSI) has been identified as a robust predictor of suicide attempts; however, less is known about correlates of NSSI that may aid in upstream prevention efforts. Prior research suggests adherence to various traditional masculine gender role norms may be positively associated with NSSI. Thus, as the U.S. military is widely recognized for promoting and rewarding such norms, this study sought to build off previous research by examining the association between adherence to various masculine gender role norms and engagement in NSSI behaviors among a mixed-sex sample of U.S. Veterans (N = 124). Results showed the norm of emotional control was most strongly associated with lifetime engagement in NSSI behaviors (including the behavior of wall-object punching), whereas the norm of violence was associated with NSSI disorder. Interestingly, exploratory analyses indicated that these associations were primarily driven by women Veterans and sexual orientation status. Overall, the results highlight the importance of assessing for adherence to masculine gender role norms among all Veterans and speak to additional avenues for future research.

Hiding in the open: Consideration of nonsuicidal self-injury by proxy as a clinically meaningful construct

Nonsuicidal self-injury (NSSI) is defined as the deliberate destruction of one's own body tissue without suicidal intent and for purposes not socially sanctioned. However, this definition limits the understanding and assessment of NSSI by excluding a clinically relevant form of NSSI that is both self-driven and associated with self-injurious intentions: NSSI by proxy. Specifically, we propose that NSSI by proxy be defined as the intentional destruction of one's own body tissue through the elicitation of another being's (e.g., human, animal) actions, wherein the agency of the person being injured is a critical facet of the behavior. We review the literature supporting the clinical relevance of this behavior, as well as its similarities to traditional NSSI. Next, we propose four behaviors that may be conceptualized as NSSI by proxy, and identify two other behaviors that warrant further investigation. Finally, we identify future directions for research in this area and implications for the assessment and treatment of NSSI.

Nonsuicidal self-injury in veterans: Prevalence, clinical characteristics, and gender differences from a national cohort

Nonsuicidal self-injury (NSSI) is a robust predictor of suicidal thoughts and behaviors; however, while there are typically only small differences observed in the prevalence of NSSI between men and women, this condition has been largely overlooked and underestimated among men. Assessing NSSI methods more common in men may address misidentification as well as allow for more precise NSSI prevalence estimates. Survey data from a national sample of Gulf War I-Era veterans (N = 1063) was used to estimate the prevalence of NSSI and compare prevalence of NSSI methods between men and women veterans. Demographic and clinical correlates of NSSI engagement were also examined. The national lifetime prevalence rate of NSSI among Gulf War I-Era veterans was 22.40%, whereas the past year prevalence rate was 8.10%. In both men and women, wall/object punching was the most common NSSI method endorsed across the lifetime. Men had slightly higher overall NSSI prevalence rates compared with women. This study highlights the need to systematically assess NSSI, particularly among veterans, to better identify, and consequently treat, NSSI in men. This is the first available prevalence estimate of NSSI to include the assessment of wall/object punching in a national sample of adult veterans.

Attention-deficit/hyperactivity disorder and nonsuicidal self-injury among veterans with complex psychiatric presentations

Prior research suggests a possible association between attention-deficit/hyperactivity disorder (ADHD) symptoms and nonsuicidal self-injury (NSSI) in veterans. However, this association has not yet been replicated. The present study sought to replicate and expand upon this association in a gender-balanced sample of veterans (N = 124), more than half of whom had a lifetime history of NSSI. Contrary to hypotheses, adult ADHD symptoms were not associated with NSSI history or disorder. Instead, our findings suggest that disorders characterized by negative affect may have greater utility for predicting NSSI versus those characterized by impulsivity. Further research in epidemiological samples is needed.

The Screen for Nonsuicidal Self-Injury: Development and initial validation among veterans with psychiatric disorders

INTRODUCTION

Nonsuicidal self-injury (NSSI) is associated with significant impairment and is a robust predictor of suicidal ideation, attempts, and death by suicide; however, the present lack of a brief screening instrument for NSSI coupled with consistent underidentification of NSSI in male adults has led to concerning rates of missed identification of NSSI.

METHODS

The Screen for Nonsuicidal Self-Injury (SNSI) is a brief, 10-item screen designed to identify individuals currently engaging in NSSI with an emphasis on behaviors more frequently endorsed by male adults. The present study examined the development and validation of the SNSI.

RESULTS

In a sample of veterans (N = 124) with complex psychiatric presentations, SNSI scores demonstrated good internal consistency and strong construct validity with area under the curve (AUC) estimates of 0.85-0.93 for the identification of NSSI disorder. SNSI scores also demonstrated good convergent (rs 0.59-0.90) and external validity (rs = 0.25-0.42), and excellent predictive validity identifying future NSSI Suicide and Life-Threatening Behavior disorder (AUC = 0.88) and NSSI behaviors (AUC = 0.90). Importantly, SNSI performance was not affected by participants' race, sex assigned at birth, or age.

CONCLUSION

The SNSI is an efficient screen to identify patients engaging in NSSI who are likely to benefit from more comprehensive assessment and treatment programs.

Comparing psychosocial functioning, suicide risk, and nonsuicidal self-injury between veterans with probable posttraumatic stress disorder and alcohol use disorder

BACKGROUND

Posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) are each common among Unites States (U.S.) military veterans and frequently co-occur (i.e., PTSD+AUD). Although comorbid PTSD+AUD is generally associated with worse outcomes relative to either diagnosis alone, some studies suggest the added burden of comorbid PTSD+AUD is greater relative to AUD-alone than to PTSD-alone. Furthermore, nonsuicidal self-injury (NSSI) is more common among veterans than previously thought but rarely measured as a veteran psychiatric health outcome. This study sought to replicate and extend previous work by comparing psychosocial functioning, suicide risk, and NSSI among veterans screening positive for PTSD, AUD, comorbid PTSD+AUD, and neither disorder.

METHODS

This study analyzed data from a national sample of N = 1046 U.S. veterans who had served during the Gulf War. Participants self-reported sociodemographic, functioning, and clinical information through a mailed survey.

RESULTS

Veterans with probable PTSD+AUD reported worse psychosocial functioning across multiple domains compared to veterans with probable AUD, but only worse functioning related to controlling violent behavior when compared to veterans with probable PTSD. Veterans with probable PTSD+AUD reported greater suicidal ideation and NSSI than veterans with probable AUD, but fewer prior suicide attempts than veterans with probable PTSD.

LIMITATIONS

This study was cross-sectional, relied on self-report, did not verify clinical diagnoses, and may not generalize to veterans of other military conflicts.

CONCLUSIONS

Findings underscore the adverse psychiatric and functional outcomes associated with PTSD and comorbid PTSD+AUD, such as NSSI, and highlight the importance of delivering evidence-based treatment to this veteran population.

The Psychosocial Correlates of Non-suicidal Self-Injury Within a Sample of Adolescents With Mood Disorder

Background

According to the integrated theoretical model, adolescents' behaviors were the outcome of the complex interplay between multiple levels. Non-suicidal self-injury (NSSI) is a serious and high prevalent problem among adolescents with mood disorders. However, a systematic perspective on psychosocial correlates among Chinese clinical adolescents is still rare.

Method

The impact of several factors at the individual (i.e., sex, age, self-esteem, and psychological distress), family (i.e., family structure, family income, and family support), and social level (i.e., living environment, peer support, and teacher support) on the frequency of NSSI behaviors were investigated in the current study. This research included 621 Chinese adolescents with mood disorders from 20 hospitals.

Results

Three-steps hierarchical regression analyses indicated that lower levels of psychological distress and higher levels of self-esteem were most associated with less frequency of NSSI behaviors. In addition, family support was negatively associated with the frequency of NSSI behaviors. After controlling the factors at individual and family levels, no significant association was found between the factors at the social level and the frequency of NSSI behaviors.

Conclusion

These findings provide preliminary support for the notion that adolescent self-esteem and family support may effectively shield them from problematic behavior; nevertheless, adolescents suffering from more emotional pain can be even riskier. Thus, further intervention strategies should consider the non-independence of individual capacities, co-combinatory effects of mood disorder, and family environment in treating those vulnerable Chinese adolescents.

Qualitative analysis of participant experiences during an ecological momentary assessment study of nonsuicidal self-injury among veterans

Ecological momentary assessment (EMA) is a useful tool to investigate antecedents and consequences of nonsuicidal self-injury (NSSI), a robust predictor of Veteran suicide risk. Despite elucidating temporal changes among dynamic variables, EMA remains underutilized to study NSSI among veterans, perhaps due to concerns of safety and utility. The present study analyzed data collected from semi-structured interviews of veterans following a 28-day EMA study of NSSI, including benefits, challenges, and recommendations for improvement. Participants included 34 veterans endorsing NSSI history, most meeting criteria for NSSI Disorder. Qualitative analysis of de-identified transcripts used the rigorous and accelerated data reduction (RADaR) technique and thematic analysis. Findings revealed all veterans reported at least one emotional/social benefit to participation, including finding it therapeutic, gaining self-awareness/insight, and improved social functioning. Challenges and recommendations were primarily technology-related, including adjustment to device use. Many expressed interest in incorporation of clinical resources, use of personal devices/VA app, and ability to share responses with providers. Assessment frequency/content was never described as triggering suicidal/nonsuicidal urges and over half of participants noted urge/behavior reduction. Results support acceptability and safety of EMA for NSSI among veterans and potential clinical utility as a psychotherapy adjunct to promote self-awareness and NSSI reduction.

Affective states and nonsuicidal self-injury (NSSI): Results from an ecological momentary assessment study of veterans with NSSI disorder

BACKGROUND

The affective states most strongly associated with nonsuicidal self-injury (NSSI) remain poorly understood, particularly among veterans. This study used ecological momentary assessment (EMA) to examine relationships between affect ratings and NSSI urges and behaviors among veterans with NSSI disorder.

METHODS

Participants (N = 40) completed EMA entries via mobile phone for 28 days (3722 total entries). Entries included intensity ratings for five basic affective states, as well as NSSI urges and behaviors, during the past 4 hours.

RESULTS

Bivariate analyses indicated that each affect variable was significantly associated with both NSSI urges and behaviors. Angry/hostile and sad were most strongly associated with both NSSI urges and behaviors. A multivariate regression revealed that angry/hostile, disgusted with self, and happy (inversely related) were contemporaneously (within the same period) associated with NSSI behaviors, whereas all five basic affective states were contemporaneously associated with NSSI urges. In a lagged model, angry/hostile and sad were associated with subsequent NSSI urges but not behaviors.

CONCLUSIONS

Findings highlight the relevance of particular affective states to NSSI and the potential utility of targeting anger in treatments for NSSI among veterans. There is a need for future EMA research study to further investigate temporal relationships between these variables.

Anger, impulsivity and wall/object punching in a sample of U.S. veterans with psychiatric disorders

Nonsuicidal self-injury (NSSI) has been identified as one of the strongest predictors of suicide attempts. Wall/object punching is a particularly prevalent form of NSSI among male veterans that has been linked to both impulsivity and anger. The objective of the present study was to examine the indirect effect of impulsivity on wall/object punching via anger. Participants included 124 veterans (32 identified as women, 92 identified as men) with at least one psychiatric disorder. A third of the sample met criteria for NSSI disorder (33.1%) with nearly a half of the remaining sample endorsing NSSI. Almost half (41.94%) of the sample endorsed wall/object punching. Consistent with our hypothesis, impulsivity was significantly associated with anger, which was, in turn, significantly associated with wall/object punching. Impulsivity was found to be indirectly related to wall/object punching via anger. These findings underscore the significance of assessing and treating anger among veterans engaging in wall/object punching. Improving our knowledge of anger and impulsivity and their relationship with this particularly prevalent form of NSSI among veterans may lead to a better understanding of suicide risk among veterans and inform future treatments.

A Rhesus Monkey Model of Non-suicidal Self-Injury

Non-suicidal self-injury (NSSI) is a type of behavioral pathology seen not only in a variety of clinical conditions but also among non-clinical populations, particularly adolescents and young adults. With the exception of rare genetic conditions that give rise to self-harming behaviors, the etiology of NSSI and the events that trigger specific episodes of this behavior remain poorly understood. This review presents the features of an important, extensively studied animal model of NSSI, namely spontaneously occurring self-injurious behavior (SIB) in rhesus macaque monkeys. We compare and contrast rhesus monkey SIB with NSSI with respect to form, prevalence rates, environmental and biological risk factors, behavioral correlates, proposed functions, and treatment modalities. Many parallels between rhesus monkey SIB and NSSI are demonstrated, which supports the validity of this animal model across several domains. Determining the etiology of spontaneously occurring SIB in monkeys, its underlying biological mechanisms, and which pharmacological agents are most effective for treating the disorder may aid in identifying potential risk factors for the occurrence of NSSI in humans and developing medications for severe cases that are resistant to conventional psychotherapeutic approaches.

Nonsuicidal Self-Injury Disorder, Borderline Personality Disorder, and Lifetime History of Suicide Attempts among Male and Female Veterans with Mental Health Disorders

BACKGROUND

Expanding on research that has identified nonsuicidal self-injury (NSSI) as a strong predictor of suicide risk, the present study examined NSSI disorder (NSSID) and borderline personality disorder (BPD) as unique contributors to lifetime suicide attempts. To our knowledge, the present study represents the first exploration of these associations among veterans.

METHODS

Participants included 124 male (74%) and female (26%) veterans diagnosed with at least one mental health disorder. Posttraumatic stress disorder (93%) and major depression (86%) were the most common mental health diagnoses. Large proportions of the sample met criteria for NSSID (48%) and BPD (40%). Suicide attempts were reported by 28% of the sample. Chi-square tests determined the bivariate associations among NSSID, BPD, history of suicide attempts, and other variables. Significant diagnostic (i.e., MDD, BPD, and NSSID) and demographic (i.e., age) characteristics were included as covariates in a logistic regression model examining the associations of BPD and NSSID with suicide attempts.

RESULTS

BPD, Χ²=11.1, p<0.001, and NSSID, Χ²=13.9, p<0.001, were uniquely associated with suicide attempts. When all significant predictors were included in the final model, only NSSID emerged as a significant contributor to suicide attempts, OR = 4.9, p < 0.001.

LIMITATIONS

Causality cannot be determined from cross-sectional analyses.

CONCLUSION

These findings highlight NSSID as a powerful and unique correlate of suicide attempts among veterans, beyond the associations of established diagnostic risk factors. Improving our understanding of the relationship between NSSID and suicide risk has the potential to inform suicide prevention efforts and improve clinical outcomes among veterans.

Exploring the role of anger in nonsuicidal self-injury in veterans

Up to 14% of veterans engage in nonsuicidal self-injury (NSSI) in their lifetime and this behavior is a relatively strong predictor of suicidal behavior compared to other identified risk factors. Further, NSSI is a clinically relevant behavior in its own right; it is associated with more severe psychopathology as well as bodily harm that sometimes requires medical intervention. Therefore, a better understanding of NSSI may help inform suicide prevention efforts as well as mental healthcare strategies for veterans. Anger may be relevant to understanding NSSI in veterans. Over 60% of veterans report difficulties managing anger and this emotion is strongly associated with engagement in NSSI. However, no research has explored the extent to which anger is present prior to NSSI or whether anger is associated with specific NSSI methods or functions in veterans. The purpose of this study was to explore whether anger was associated with engagement in specific NSSI methods, and whether anger uniquely predicted any functions of NSSI while controlling for the presence of other basic negative emotions (fear and sadness). An existing dataset of 61 veterans who reported engaging in NSSI in the past year was analyzed. Results indicated anger was the most common emotional antecedent to NSSI. Further, anger was associated with several methods of NSSI including burning oneself with a cigarette, carving pictures, designs or other marks into skin, sticking sharp objects into skin, severely scratching oneself, head banging, punching oneself, and punching walls or objects. Finally, when controlling for the presence of other negative emotions, anger was associated with engaging in NSSI to relieve tension, stop feeling numb, communicate with others, feel alive, get help from others, and prove to oneself how bad things are. These results highlight the importance of assessing and treating dysregulated anger in veterans who engage in self-harming behavior.

Anger precedes and predicts nonsuicidal self-injury in veterans: Findings from an ecological momentary assessment study

Veterans have high rates of suicide, and nonsuicidal self-injury (NSSI) is one of the strongest predictors of suicide risk; however, there is presently little known about antecedents of NSSI that might inform intervention efforts. Accumulating research suggests that anger and hostility play an important role in NSSI, but whether these emotions precede and predict NSSI is currently unknown. The aim of the current study was to examine the temporal relationships between anger/hostility and NSSI urges and behavior among veterans diagnosed with NSSI disorder. Our hypothesis was that angry/hostile affect would predict subsequent NSSI urge and engagement, but not vice versa. Forty veterans with NSSI disorder completed a 28-day ecological momentary assessment study with three daily prompts to report on their affect and NSSI urges and engagement. Multilevel cross-lagged path modeling was used to determine the direction of effects between angry/hostile affect and NSSI urges and engagement over time. Consistent with our hypothesis, results indicated that the lagged effects of angry/hostile affect on subsequent NSSI urge and engagement were significant, whereas the lagged effects of NSSI urge and engagement on angry/hostile affect were not significant. Findings highlight the importance of assessing and treating anger among veterans who engage in NSSI.

Diagnostic Correlates of Nonsuicidal Self-Injury Disorder among Veterans with Psychiatric Disorders

With its recent inclusion in the Diagnostic and Statistical Manual, nonsuicidal self-injury disorder (NSSID) has received limited research attention, especially in samples of military veterans. The present study sought to identify diagnostic predictors of NSSID within a veteran sample. Study participants included 124 veterans with at least one psychiatric diagnosis. Chi-square tests and t-tests evaluated bivariate associations between NSSID and twenty diagnostic correlates. Logistic regression models identified psychiatric disorders that were unique correlates of NSSID among veterans. Veterans with lifetime NSSID (n = 59) met criteria for a greater number of lifetime disorders than veterans with other psychiatric disorders. Bivariate associations were noted between NSSID and borderline personality disorder, depression, obsessive-compulsive disorder, generalized anxiety disorder, and cannabis use disorder. In the logistic regression model, only borderline personality disorder (AOR = 7.67) and obsessive-compulsive disorder (AOR = 3.23) continued to be associated with NSSID. The present study represents the first examination of the association between NSSID and psychiatric disorders among veterans. The findings shed light on psychiatric disorders associated with lifetime NSSID in veterans, with special consideration toward obsessive-compulsive disorder as a risk factor for NSSID.

Psychometric Properties of the Chinese Version of the Functional Assessment of Self-Mutilation (FASM) in Chinese Clinical Adolescents

BACKGROUND

Functional Assessment of Self-Mutilation (FASM) is one of the most widely used tools assessing adolescent's non-suicidal self-injury. However, the Chinese version of FASM (C-FASM) is lacking. The present study aimed to adapt the FASM to the Chinese patients and examine its reliability and validity.

METHODS

The original English version of the FASM was translated into Chinese following Brislin's model of cross-culture translation, and then, pilot study and cognitive interview were carried out with 15 adolescent patients to assess the acceptability and comprehensibility of all items. The items were subsequently tested in a sample of 621 Chinese adolescent patients recruited by 20 psychiatric or general hospitals in nine provinces across China. We examined the distribution of responses for each item. Factor analysis, Cronbach's α and McDonald's Ω, intraclass coefficient, and Spearman's rank correlations were deployed to assess the dimensional structure, internal consistency reliability, test-retest reliability, and criterion validity.

RESULTS

The final adapted C-FASM included a 10-item method checklist and a 15-item function checklist of NSSI, and other characteristics of NSSI. C-FASM exhibited acceptable internal consistency (α = 0.81 and Ω = 0.80 for method checklist; α = 0.80 and Ω = 0.76 for function checklist) and test-retest reliability (method checklist: 0.79; function checklist: 0.87). Factor analysis for NSSI functions yielded a three-factor model with a good model fit. In addition, the instrument showed an expected correlation with the instrument of the Deliberate Self-Harm Behavior Inventory (r = 0.84, p < 0.001).

CONCLUSIONS

The C-FASM has good content, structural validity, and reliability. The instrument can be helpful to Chinese adolescents as a comprehensive measure of NSSI behaviors.

Posttraumatic Stress Disorder, Suicidal Ideation, and Suicidal Self-Directed Violence Among U.S. Military Personnel and Veterans: A Systematic Review of the Literature From 2010 to 2018

Rates of suicide and posttraumatic stress disorder remain high among United States military personnel and veterans. Building upon prior work, we conducted a systematic review of research published from 2010 to 2018 regarding: (1) the prevalence of suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans diagnosed with posttraumatic stress disorder; (2) whether posttraumatic stress disorder was associated with suicidal ideation, suicide attempt, and suicide among United States military personnel and veterans. 2,106 titles and abstracts were screened, with 48 articles included. Overall risk of bias was generally high for studies on suicidal ideation or suicide attempt and low for studies on suicide. Across studies, rates of suicidal ideation, suicide attempt, and suicide widely varied based on study methodology and assessment approaches. Findings regarding the association between posttraumatic stress disorder diagnosis with suicidal ideation and suicide were generally mixed, and some studies reported that posttraumatic stress disorder was associated with lower risk for suicide. In contrast, most studies reported significant associations between posttraumatic stress disorder and suicide attempt. These findings suggest complex associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, which are likely influenced by other factors (e.g., psychiatric comorbidity). In addition, most samples were comprised of veterans, rather than military personnel. Further research is warranted to elucidate associations between posttraumatic stress disorder and suicidal ideation, suicide attempt, and suicide, including identification of moderators and mediators of this relationship. Addressing this among United States military personnel, by gender, and in relation to different trauma types is also necessary.

Characteristics of nonsuicidal self-injury among veterans

OBJECTIVE

The current study aimed to (a) assess basic nonsuicidal self-injury (NSSI) characteristics using a validated clinical interview among a sample of veterans not recruited for specific diagnostic or environmental criteria and (b) examine the relation between NSSI and medical severity of prior suicide attempts (SAs) among veterans.

DESIGN

We conducted secondary data analyses among a combined sample of veterans (N = 165) from two parent studies conducted at a large VA Medical Center that implemented identical recruitment protocols. No psychiatric criteria were utilized for inclusion or exclusion purposes.

RESULTS

Approximately 16% of participants reported NSSI history and almost 21% reported SA history. NSSI history was associated with probability of prior SA but not the medical severity of prior SA.

CONCLUSIONS

NSSI is a prevalent concern among veterans and is associated with probability of SA. It remains unclear whether prior NSSI is associated with more medically serious SA in this population.

Predicting the incidence of non-suicidal self-injury in college students

Background:

Despite increased awareness that non-suicidal self-injury (NSSI) poses a significant public health concern on college campuses worldwide, few studies have prospectively investigated the incidence of NSSI in college and considered targeting college entrants at high risk for onset of NSSI.

Methods:

Using data from the Leuven College Surveys (n = 4,565; 56.8%female, Mage = 18.3, SD = 1.1), students provided data on NSSI, sociodemographics, traumatic experiences, stressful events, perceived social support, and mental disorders. A total of 2,163 baseline responders provided data at a two-year annual follow-up assessment (63.2% conditional response rate).

Results:

One-year incidence of first onset NSSI was 10.3% in year 1 and 6.0% in year 2, with a total of 8.6% reporting sporadic NSSI (1–4 times per year) and 7.0% reporting repetitive NSSI (≥ 5 times per year) during the first two years of college. Many hypothesized proximal and distal risk factors were associated with the subsequent onset of NSSI (ORs = 1.5–18.2). Dating violence prior to age 17 and severe role impairment in daily life were the strongest predictors. Multivariate prediction suggests that an intervention focused on the 10% at highest risk would reach 23.9% of students who report sporadic, and 36.1% of students who report repetitive NSSI during college (cross-validated AUCs =.70–.75).

Discussion:

The college period carries high risk for the onset of NSSI. Individualized web-based screening may be a promising approach for detecting young adults at high risk for self-injury and offering timely intervention.

Nonsuicidal Self-Injury and Borderline Personality Features as Risk Factors for Suicidal Ideation Among Male Veterans With Posttraumatic Stress Disorder

U.S. veterans are at increased risk for suicide compared to their civilian counterparts and account for approximately 20% of all deaths by suicide. Posttraumatic stress disorder (PTSD) and borderline personality features (BPF) have each been associated with increased suicide risk. Additionally, emerging research suggests that nonsuicidal self-injury (NSSI) may be a unique risk factor for suicidal behavior. Archival data from 728 male veterans with a PTSD diagnosis who were receiving care through an outpatient Veterans Health Administration (VHA) specialty PTSD clinic were analyzed. Diagnosis of PTSD was based on a structured clinical interview administered by trained clinicians. A subscale of the Personality Assessment Inventory was used to assess BPF, and NSSI and suicidal ideation (SI) were assessed by self-report. Findings revealed that NSSI (58.8%) and BPF (23.5%) were both relatively common in this sample of male veterans with PTSD. As expected, each condition was associated with significantly increased odds of experiencing SI compared to PTSD alone, odds ratios (ORs) = 1.2-2.6. Moreover, co-occurring PTSD, NSSI, and BPF were associated with significantly increased odds of experiencing SI compared with PTSD, OR = 5.68; comorbid PTSD and NSSI, OR = 2.57; and comorbid PTSD and BPF, OR = 2.13. The present findings provide new insight into the rates of NSSI and BPF among male veterans with PTSD and highlight the potential importance of these factors in suicide risk.
