Diagnosis and Characterization of DSM-5 Nonsuicidal Self-Injury Disorder Using the Clinician-Administered Nonsuicidal Self-Injury Disorder Index

A self-determination theory perspective on the relationship between emotion regulation styles, mindfulness facets, and well-being in adults with self-injury

BACKGROUND

The relevance of emotion regulation (ER) difficulties to nonsuicidal self-injury (NSSI; the deliberate destruction of one's bodily tissue without suicidal intent) has been repeatedly documented. Recently, specific mindfulness facets (i.e., awareness, nonjudging, describing) have been proposed as mechanisms that explain this relationship. The present study sought to extend this line of inquiry by exploring the mediating role of mindfulness facets in the relation between self-determination theory-based ER styles (i.e., integrative ER, suppressive ER, emotion dysregulation) and indices of positive and negative well-being (i.e., subjective vitality, NSSI difficulties), while controlling for gender, in adults with recent NSSI engagement.

METHODS

US adults with a history of more than one occurrence of NSSI within the last year (n = 222) completed online measures of ER styles, mindfulness facets, subjective vitality, and NSSI difficulties.

RESULTS

A mediation model indicated that the effects of ER styles on positive and negative well-being were explained by specific mindfulness facets (i.e., awareness, nonjudging, nonreactivity, describing).

CONCLUSIONS

The present study provides preliminary evidence that facets of dispositional mindfulness may be mechanisms through which ER styles impact positive and negative indices of well-being in adults with lived experience of NSSI.

DSM-5 Non-Suicidal Self-Injury Disorder in a Clinical Sample of Adolescents with Recurrent Self-Harm Behavior

INTRODUCTION

Non-suicidal self-injury disorder (NSSID) is a new diagnosis proposed in DSM-5 with a need of further study, especially in adolescent clinical populations where non-suicidal self-injury (NSSI) is particularly prevalent. We aimed to study characteristics of NSSID and estimate an optimal cutoff frequency level of NSSI behavior.

METHODS

Data were collected from 103 outpatient adolescents (ages 12-18) with recurrent self-harm behavior.

RESULTS

Adolescents with NSSID reported significantly more frequent NSSI behavior and suicide attempts than adolescents without NSSID. Frequency of NSSI, global functioning, depressive symptoms, number of self-harm methods and anxiety symptoms best discriminated between adolescents with and without NSSID. An optimal cutoff level for a diagnosis of NSSID was found to be ≥15 days with NSSI during the last year, which led to a reduction in the rate of adolescents diagnosed with NSSID from 54% to 46%.

CONCLUSION

This study shows that NSSID is a highly impairing disorder characterized by high risk of multiple NSSI and suicide attempts, decreased functioning and other associated psychiatric disorders. Clinical awareness of these risks are important to ensure early detection and treatment. Future prospective longitudinal studies are needed to further validate the characteristics of the NSSID diagnosis and its clinical utility.

Measurement properties of tools used to assess self-harm in autistic and general population adults

Autistic people are at increased risk of experiencing self-harm compared to the general population. However, it is unclear which tools are being used to assess self-harm in autistic people, or whether existing tools need to be adapted for this group. This two-stage systematic review aimed to identify tools used to assess self-harm in autistic and general population adults, evaluate these tools on their measurement properties, and make recommendations for their appropriate use in research and clinical practice. Four databases were systematically searched (PsycINFO, Embase, MEDLINE and Web of Science). Eight frequently used self-harm assessment tools were identified and assessed for risk of bias, criteria for good measurement properties, and quality of evidence using the COSMIN checklist. Of these, two tools had sufficient evidence of internal consistency (ISAS, QNSSI), and one had been frequently used with autistic adults (NSSI-AT). These three tools may have potential for use with autistic adults but require further investigation for content validity and measurement properties in the autistic population. More research and potential adaptations to current self-harm assessment tools are recommended in order to better conceptualise and understand self-harm and its measurement in autism.

Latent profiles and psychosocial correlates of persistent self-injury among incarcerated adults

Self-directed violence (SDV), including both suicide and non-suicidal self-injury, represents a major challenge for carceral systems. Persistent self-injury (PSI) is an understudied SDV subtype, especially within the carceral context. The present study addressed three research questions: (a) do naturally occurring SDV subgroups occur within a carceral population (e.g., PSI versus other classes); (b) how SDV groups may be differentiated by verbal or behavioral SDV; and (c) whether demographic, mental health, and incarceration-related factors are associated with SDV subgroups. We conducted a secondary analysis of existing data from a statewide carceral electronic medical record (N = 3527). Latent class analysis supports two SDV subtypes: episodic and persistent self-injury. The PSI class was characterized by significantly greater verbal expressions and behavioral acts of SDV compared to the episodic group. Correlates of the PSI subtype included older age, male sex, prior SDV, and lower depressive symptoms. Findings are discussed with respect to the proposed Diagnostic and Statistical Manual self-injury focused disorder, influential factors on SDV in carceral settings, and recommendations for future research and practice.

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.

Online and school bullying roles: are bully-victims more vulnerable in nonsuicidal self-injury and in psychological symptoms than bullies and victims?

BACKGROUND

Bullying leads to adverse mental health outcomes and it has also been linked to nonsuicidal self-injury (NSSI) in community adolescents. It is not clear whether different roles of bullying (bully, victim, bully-victim) are associated with NSSI, furthermore the same associations in cyberbullying are even less investigated.

METHODS

The aim of the current study was to test whether students involved in school or online bullying differed from their not involved peers and from each other in psychological symptoms (externalizing and internalizing problems) and in NSSI severity (number of episodes, number of methods). Furthermore, mediation models were tested to explore the possible role of externalizing and internalizing problems in the association of school and online bullying roles with NSSI. In our study, 1011 high school students (66.07% girls; n = 668), aged between 14 and 20 years (Mage = 16.81; SD = 1.41) participated.

RESULTS

Lifetime prevalence of at least one episode of NSSI was 41.05% (n = 415). Students involved in bullying used more methods of NSSI than not involved adolescents. In general, victim status was associated mostly with internalizing symptoms, while bully role was more strongly associated with externalizing problems. Bully-victims status was associated with both types of psychological problems, but this group did not show a significantly elevated NSSI severity compared to other bullying roles. Externalizing and internalizing problems mediated the relationship between bullying roles and NSSI with different paths at different roles, especially in case of current NSSI that happened in the previous month.

CONCLUSIONS

Results highlight that students involved in bullying are more vulnerable to NSSI and to psychological symptoms compared to their peers who are not involved in bullying. It is suggested that bullying roles, especially bully-victim status, need to be identified in school and online settings and thus special attention should be addressed to them to reduce psychological symptoms and NSSI, for example by enhancing adaptive coping skills.

Examining the daily relationship between guilt, shame, and substance use among veterans with psychiatric disorders

Background

Shame and guilt are key emotions known to amplify trauma-related symptoms in veterans. Maintenance of symptoms is facilitated by avoidance behaviors, such as substance use. However, limited research has examined the associations between shame, guilt, and substance use in daily life.

Methods

The current study sought to examine the cross-lagged association between shame, guilt, and substance use. Forty veterans completed 28 days of experience sampling reporting on their current emotional experiences and use of substances.

Results

Results suggest a reciprocal relationship among shame and guilt and substance use, such that shame and guilt separately predicted subsequent substance use, and substance use predicted subsequent shame and guilt.

Conclusions

These results highlight the dynamic relationship among shame, guilt, and substance use and suggest the potential value of conceptualizing these clinical targets as mutually reinforcing to inform integrative intervention strategies that can interrupt the in-the-moment cascade of negative consequences.

Love Is Not All You Need: Understanding the Association Between Relationship Status and Relationship Dysfunction With Self-Directed Violence in Veterans

INTRODUCTION

Research indicates that being married is associated with reduced risk of suicide and self-directed violence (SDV) relative to being divorced. Simultaneously, difficulties within relationships predict poorer health outcomes. However, research on relationship status rarely examines relationship functioning, obfuscating the joint contribution of these variables for SDV risk.

METHOD

Veterans (N = 1,049) completed a survey that included assessment of relationship status, relationship functioning, and SDV history. Logistic regression models tested how (a) relationship status, (b) relationship dysfunction, and (c) being divorced compared to being in a low- or high-dysfunction relationship were associated with SDV, controlling for several intrapersonal risk factors.

RESULTS

Veterans in a relationship did not differ in SDV history compared to divorced/separated veterans. However, more dysfunction within relationships was associated with greater odds of a history of SDV and suicidal cognitions. Finally, SDV histories were more likely among veterans endorsing high-dysfunction relationships compared with (a) low-dysfunction relationships and (b) divorced veterans.

CONCLUSION

It may be insufficient to only consider relationship status when evaluating interpersonal risk factors for SDV. A single item assessing relationship dysfunction was associated with enacted SDV and suicidal cognitions over and above intrapersonal risk factors. Integrating such single-item measures into clinical practice could improve identification and subsequent tailored intervention for veterans at greater risk for SDV.

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.

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.

Association between alexithymia and non-suicidal self-injury in psychiatric patients: the mediating role of self-esteem and the moderating role of emotional intelligence

BACKGROUND

Raffagnato's theory claims that if people have no words to express their emotions (alexithymia), they express themselves by venting or through non-suicidal self-injury (NSSI). However, these associations have not been confirmed in psychiatric patients. This study explored the relationship between alexithymia and NSSI in psychiatric patients and the potential underlying psychological mechanisms.

METHODS

This retrospective study involved face-to-face interviews with 449 outpatients consecutively recruited from West China Hospital. Alexithymia, self-esteem, NSSI, and emotional intelligence (EI) were measured. The moderating role of EI and the mediating role of self-esteem between alexithymia and NSSI were also explored. Logistic regressions were used to examine whether sociodemographic, clinical variables and alexithymia were independently associated with NSSI.

RESULTS

The DSM-5 NSSI disorder and alexithymia prevalences were found to be 32.5% and 45.2%. When the other covariables were controlled for, the alexithymic patients were found to be at increased odds (OR 2.76) of engaging in NSSI behaviors. These results confirmed the strong associations between alexithymia, low self-esteem, and NSSI risk. Lower EI was found to be related to the connections between alexithymia and NSSI. Except for the lower risk in anxiety patients, the risk of NSSI was similar for patients with other mental disorders, CONCLUSION: This study revealed the psychological mechanisms through which alexithymia increases the risk of NSSI. Therefore, to reduce NSSI risk, screening for alexithymia should be emphasized. Self-esteem as a targeted psychological intervention could also assist in mitigating the process from alexithymia to NSSI behaviors, and EI training for psychiatric patients could weaken the relationship between alexithymia and NSSI.

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.

Non-suicidal self-injury motivations in the light of self-harm severity indicators and psychopathology in a clinical adolescent sample

Introduction

Adolescents with psychiatric problems are also considered a vulnerable population in terms of non-suicidal self-injury (NSSI). In the current study, we examined the associations of interpersonal and intrapersonal NSSI motivations with several NSSI severity indicators and psychopathological characteristics.

Materials and methods

In a cross-sectional research design, 158 adolescents (83.5% girls; mean age = 16.10 years; SD = 1.49) who have received inpatient or outpatient psychiatric treatment completed the Inventory of Statements About Self-Injury, the Strengths and Difficulties Questionnaire, and the Self-Critical Rumination Scale.

Results

More than two-thirds of the sample (75.3%; n = 119) reported at least one episode of NSSI in their life, and 45.38% (n = 54) have engaged in NSSI in the past month (current self-injury). The results indicated that only intrapersonal NSSI functions were linked to NSSI severity indicators (current and repetitive NSSI, versatility), interpersonal functions were not. Furthermore, a number of psychopathological features (co-occurring mental disorders, presence of a mood disorder, more internalizing mental illness symptoms, and more pronounced self-critical rumination) were associated with engaging in NSSI for intrapersonal reasons. We also identified other differences within the specific intrapersonal NSSI motivations. It should be highlighted that the anti-suicide function of NSSI behaved in exactly the opposite way as the other intrapersonal motivations.

Discussion

All this points to the fact that in clinical settings, detailed assessment of NSSI motivations and severity indicators can help to develop a more effective treatment plan.

Interrogating nonsuicidal self-injury disorder through a feminist psychiatric disability theory framework

This article explores the proposed psychiatric diagnostic category of nonsuicidal self-injury disorder (NSSID) through the lens of feminist psychiatric disability theory. Mobilising insights from labelling theory's accounts of stigma and recovery, in conjunction with critical and feminist disability theory's attention to emotional and physical pain, we suggest that a feminist psychiatric disability approach to NSSID can illuminate the limits of a fully demedicalised engagement with self-injury. While remaining critical of psychiatrisation processes, we explore the implications of 'strategic (dis)identifications' with illness labels as mechanisms through which to manage and access care, treatment and recovery. Such a nuanced account engenders more deeply material considerations of pain, stigma, treatment and 'cure' at the site of NSSID, opening new avenues of engagement with self-injury for sociologists and critical disability scholars alike.

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.

A Machine Learning Approach for Predicting Non-Suicidal Self-Injury in Young Adults

Artificial intelligence techniques were explored to assess the ability to anticipate self-harming behaviour in the mental health context using a database collected by an app previously designed to record the emotional states and activities of a group of subjects exhibiting self-harm. Specifically, the Leave-One-Subject-Out technique was used to train classification trees with a maximum of five splits. The results show an accuracy of 84.78%, a sensitivity of 64.64% and a specificity of 85.53%. In addition, positive and negative predictive values were also obtained, with results of 14.48% and 98.47%, respectively. These results are in line with those reported in previous work using a multilevel mixed-effect regression analysis. The combination of apps and AI techniques is a powerful way to improve the tools to accompany and support the care and treatment of patients with this type of behaviour. These studies also guide the improvement of apps on the user side, simplifying and collecting more meaningful data, and on the therapist side, progressing in pathology treatments. Traditional therapy involves observing and reconstructing what had happened before episodes once they have occurred. This new generation of tools will make it possible to monitor the pathology more closely and to act preventively.

The Effectiveness of Emotion Regulation Therapy for Adolescent Females With Nonsuicidal Self-Injury Disorder: A Mixed-Method Study

Given the prevalence and consequences of the nonsuicidal self-injury disorder (NSSID) among adolescents, this study aimed to analyze the effectiveness of emotion regulation therapy (ERT) among adolescents with NSSID. The present study is an after-trial, mixed-method intervention design. Six participants completed questionnaires at baseline, during their treatment, and follow-up. In-depth interviews were made after the intervention. The quantitative findings were consistent with the pattern of the qualitative findings that prominently supported the treatment efficiency concerning the difficulties in emotion regulation. The research findings indicated that ERT had a positive effect on adolescents with NSSID.

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.

Different Ways to Drown Out the Pain: A Meta-Analysis of the Association Between Nonsuicidal Self-Injury and Alcohol Use

OBJECTIVE

There is a significant overlap in the motivations for nonsuicidal self-injury (NSSI) and alcohol use. Moreover, several theories would predict that more frequent alcohol use is likely associated with more NSSI engagement. Still, the size and direction of this association has not been well documented in the literature.

METHOD

To address this gap, the goal of this article was to conduct a meta-analysis of the relation between alcohol use and NSSI.

RESULTS

Across 57 samples and 141,669 participants, we found that there was a significant positive association between NSSI and alcohol use, odds ratio = 1.78, 95% confidence interval [1.53, 2.07], k = 64, m = 52. Moderator analyses found that this effect was stronger for younger samples and samples with more severe alcohol use problems.

CONCLUSIONS

These results help establish a link between NSSI and alcohol use. Implications and future directions for NSSI research and intervention are discussed.HighlightsThere are several reasons to think that NSSI and alcohol use are linked.No reviews or meta-analyses have been conducted.We found a significant and small effect linking greater NSSI with greater alcohol use.

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.

The Danish High-Risk and Resilience Study-VIA 15 - A Study Protocol for the Third Clinical Assessment of a Cohort of 522 Children Born to Parents Diagnosed With Schizophrenia or Bipolar Disorder and Population-Based Controls

BACKGROUND

Children born to parents with severe mental illness have gained more attention during the last decades because of increasing evidence documenting that these children constitute a population with an increased risk of developing mental illness and other negative life outcomes. Because of high-quality research with cohorts of offspring with familial risk and increased knowledge about gene-environment interactions, early interventions and preventive strategies are now being developed all over the world. Adolescence is a period characterized by massive changes, both in terms of physical, neurologic, psychological, social, and behavioral aspects. It is also the period of life with the highest risk of experiencing onset of a mental disorder. Therefore, investigating the impact of various risk and resilience factors in adolescence is important.

METHODS

The Danish High-Risk and Resilience Study started data collection in 2012, where 522 7-year-old children were enrolled in the first wave of the study, the VIA 7 study. The cohort was identified through Danish registers based on diagnoses of the parents. A total of 202 children had a parent diagnosed with schizophrenia, 120 children had a parent diagnosed with bipolar disorder, and 200 children had parents without these diagnoses. At age 11 years, all children were assessed for the second time in the VIA 11 study, with a follow-up retention rate of 89%. A comprehensive assessment battery covering domains of psychopathology, neurocognition, social cognition and behavior, motor development and physical health, genetic analyses, attachment, stress, parental functioning, and home environment was carried out at each wave. Magnetic resonance imaging scans of the brain and electroencephalograms were included from age 11 years. This study protocol describes the third wave of assessment, the VIA 15 study, participants being 15 years of age and the full, 3-day-long assessment battery this time including also risk behavior, magnetoencephalography, sleep, and a white noise paradigm. Data collection started on May 1, 2021.

DISCUSSION

We will discuss the importance of longitudinal studies and cross-sectional data collection and how studies like this may inform us about unmet needs and windows of opportunity for future preventive interventions, early illness identification, and treatment in the future.

E-cigarettes and non-suicidal self-injury: Prevalence of risk behavior and variation by substance inhaled

BACKGROUND

Nicotine and cannabis inhalation through vaping or electronic delivery systems has surged among young adults in the United States, particularly during the coronavirus disease pandemic. Tobacco and marijuana use are associated with select adverse mental health outcomes, including symptoms of major depressive disorder and suicidal behaviors. Given the need for addiction specialists to treat problematic substance use with an integrated approach, the association between non-suicidal self-injury (NSSI) and use of e-cigarettes, tobacco, marijuana, and alcohol was examined among a diverse sample of college students.

METHODS

Healthy Minds Study data from 47,016 weighted observations, collected from college students in the 2018-2019 academic year, was used to explore associations between NSSI-related behaviors and past 30-day use of a vaping product (nicotine or marijuana). These relationships were assessed among those using vaping products only, and then among individuals using vaping products and alcohol, conventional cigarettes, and/or marijuana. Hierarchical logistic regression models estimating the relationship between vaping and NSSI were computed to adjust for the effects of demographic factors, symptomatology of psychiatric disorders, and concurrent use of other substances.

RESULTS

A fifth (22.9%) of respondents disclosed past 12-month NSSI; they were significantly more likely to screen positive for depression or anxiety compared to young adults without NSSI. Rates of using vaping products, conventional cigarettes, marijuana, or other substances were higher among students with NSSI even after controlling for potential cofounders. Additionally, students who used a THC-based liquid in their e-cigarettes were more likely to endorse NSSI in comparison to those who used "just flavoring." However, young adults who vaped were less likely to disclose frequent NSSI-related behaviors than their peers who did not vape.

CONCLUSIONS

These findings revealed an association between past 12-month NSSI and past 30-day vaping in a sample of young adults. Further surveillance among college populations and examination of potential sociodemographic confounders is necessary to confirm these findings and advance the substance use and addiction field.

The Impact of COVID on Adolescent Mental Health, Self-Harm and Suicide: How Can Primary Care Provider Respond? A Position Paper of the European Academy of Pediatrics

Adolescents aged 10 to 19 live a period of their life marked by opportunities and vulnerabilities during which the issue of mental health is of prime importance. Since several decades, and especially since the start of the COVID pandemic, mental health problems and disorders among adolescents have increased around the world. Depression, self-harm and suicidal behavior are common during this period of life, and pediatricians can play a pivotal role in identifying affected or vulnerable youngsters. This article describes risk factors for self-harm and suicidal behavior and reviews how primary care pediatricians and health professionals can respond to such situations. This scoping review is based on existing evidences as well as the authors clinical experience. It suggests concrete actions that can be taken to secure the life of at risk teenagers, and discusses how to organize the transfer to mental health professionals when needed.

Functions of nonsuicidal self-injury in a Hungarian community adolescent sample: a psychometric investigation

BACKGROUND

The Inventory of Statements About Self-Injury (ISAS) is a psychometrically valid tool to evaluate the motives of nonsuicidal self-injury (NSSI), but there are a few studies that test gender differences in the factor structure of the measurement. However, several differences across gender were identified in NSSI (e.g., in prevalence, methods, functions). Therefore, our study focused on further analyses of the dimensionality of the ISAS functions.

METHODS

Among Hungarian adolescents with a history of NSSI (N = 418; 70.6% girls; mean age was 16.86, SD = 1.45), confirmatory factor analysis and exploratory structural equation modeling frameworks were used to test the factor structure of the ISAS part II.

RESULTS

Results support the two-factor structure of the questionnaire. Intrapersonal and interpersonal motivation factors emerged in the whole sample, but this factor structure varied across gender. Among girls, intrapersonal motivation of NSSI was associated with higher loneliness, more inflexible emotion regulation, and a more pronounced level of internalizing and externalizing mental illness symptoms.

CONCLUSIONS

Our findings provide sufficiently solid arguments for the need to examine NSSI functionality separately for adolescent girls and boys because there were clear gender differences in the motives underlying NSSI. In addition, precise scanning of patterns of NSSI functions may further help us to identify the most at-risk adolescents regarding self-injury.

Relationships between Non-Suicidal Self-Injury and Other Maladaptive Behaviors: Beyond Difficulties in Emotion Regulation

Non-suicidal self-injury (NSSI) co-occurs with both other maladaptive behaviors (e.g., aggression) and emotion dysregulation. However, the extent to which these maladaptive behaviors are linked to NSSI independent of emotion dysregulation is unclear. The present study examined relationships between NSSI and six other maladaptive behaviors among university undergraduates. When controlling for demographic variables, emotion dysregulation, and other maladaptive behaviors, binge eating, purging, illicit drug use, and physical aggression were each related to lifetime NSSI history and/or severity. No maladaptive behaviors were significantly related to the presence of current diagnostic-level NSSI in these multivariate analyses. Results suggest that some maladaptive behaviors may relate uniquely to NSSI risk independent of emotion dysregulation, highlighting the importance of considering such behaviors in self-injury assessment and treatment.

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.

Clinical assessment of non-suicidal self-injury: A systematic review of instruments

There has been an increase in the number of assessment instruments for non-suicidal self-injury (NSSI). However, previous reviews are inconsistent and do not provide a comprehensive psychometric assessment of the instruments. This study aimed to systematically assess and compare the psychometric properties of clinically relevant instruments to measure NSSI in any population. Through a systematic review guided by COSMIN and PRISMA, two searches were conducted in English and Spanish in February 2020 in 13 databases including grey literature. Of the 7,813 initial records, 152 validations were extracted. From these, 83 instruments (22 versions or adaptations) were excluded for not measuring NSSI, having no potential clinical utility or not including psychometric properties. Finally, 26 (22 versions, 35 adaptations and 19 creations) instruments measuring NSSI were included. Predominantly, the studies were North American self-reports in English for community adolescents, adaptations or versions emanating from a small number of instruments. Twenty-six indicators were categorized to assess NSSI. The most frequent instruments are structured interviews, and their indicators were related to NSSI function and topography. Evidence of validity and reliability was positive but limited. Despite the high number of instruments and diversity of evaluations, we found no instrument with sufficient evidence for clinical assessment. Findings broadly overview NSSI assessment instruments' current use and future improvement in clinical and research settings.

Potential Transdiagnostic Lipid Mediators of Inflammatory Activity in Individuals With Serious Mental Illness

Mental disorders are heterogeneous and psychiatric comorbidities are common. Previous studies have suggested a link between inflammation and mental disorders. This link can manifest as increased levels of proinflammatory mediators in circulation and as signs of neuroinflammation. Furthermore, there is strong evidence that individuals suffering from psychiatric disorders have increased risk of developing metabolic comorbidities. Our group has previously shown that, in a cohort of low-functioning individuals with serious mental disorders, there is increased expression of genes associated with the NLRP3 inflammasome, a known sensor of metabolic perturbations, as well as increased levels of IL-1-family cytokines. In the current study, we set out to explore the interplay between disease-specific changes in lipid metabolism and known markers of inflammation. To this end, we performed mass spectrometry-based lipidomic analysis of plasma samples from low-functioning individuals with serious mental disorders (n = 39) and matched healthy controls (n = 39). By identifying non-spurious immune-lipid associations, we derived a partial correlation network of inflammatory markers and molecular lipids. We identified levels of lipids as being altered between individuals with serious mental disorders and controls, showing associations between lipids and inflammatory mediators, e.g., osteopontin and IL-1 receptor antagonist. These results indicate that, in low-functioning individuals with serious mental disorders, changes in specific lipids associate with immune mediators that are known to affect neuroinflammatory diseases.

A typology of nonsuicidal self-injury in a clinical sample: A latent class analysis

Nonsuicidal self‐injury(NSSI) is a behavioural concern and can present in diverse ways, varying by method, frequency, severity, function and so forth. The possible combinations of these features of NSSI produce an array of profiles that makes evaluation and management of this behaviour challenging. The aim of this study was to build upon previous work that reduces the heterogeneity of NSSI patterns by using latent class analysis (LCA) to identify a typology of NSSI. Participants consisted of 235 outpatients aged 14–35 years attending a tertiary psychiatric hospital in Singapore who had reported at least one NSSI behaviour within the last year. Eight indicators captured using the Functional Assessment of Self‐Mutilation were used in the LCA: frequency of NSSI, length of contemplation before engaging in NSSI, usage of more than three NSSI methods, suicidal ideation and four psychological functions of NSSI, that is, social‐positive, social‐negative, automatic‐positive and automatic‐negative. The LCA revealed three distinct groups: Class 1—Experimental/Mild NSSI, Class 2—Multiple functions NSSI/Low Suicide Ideation and Class 3—Multiplefunctions NSSI/Possible Suicide Ideation. Multinomial logistic regression analyses were conducted to examine the associations between class membership and sociodemographic variables as well as measures of emotion dysregulation, childhood trauma, depression and quality of life. Females were overrepresented in Class 3. In general, Class 3 had the poorest scores followed by Class 2. Our analyses suggest that different NSSI subtypes require different treatment indications. Profiling patterns of NSSI may be a potentially useful step in guiding treatment plans and strategies.

DSM-5 Non-Suicidal Self-Injury Criteria in a Clinical Sample of Self-Harming Mexican Adolescents

INTRODUCTION

The DSM-5 diagnostic criteria for non-suicidal self-injury (NSSI) needs to be validated in non-European populations. The aims of this study were to determine how common NSSI was in a sample of self-harming Mexican adolescents and examine the associated variables.

METHODS

We examined the medical records of 585 adolescents with a history of self-injurious behaviour who attended a public hospital in Mexico City from 2005 to 2012. A group of experts established the diagnosis according to the DSM-5. The clinical and demographic characteristics of patients with and without NSSI were compared.

RESULTS

NSSI was diagnosed in 351 patients (60%) with evidence of self-harm. The main reasons for not being diagnosed were a previous suicide attempt (criterion A, 158 subjects [26.87%]) and another diagnosis that better explained the self-injurious behaviour (criterion F, 60 subjects [10.25%]). The NSSI group had a higher proportion of males (26.5% vs 16.2%) and patients with behavioural disorders (28.5% vs 13.7%). These patients were also found to seek psychiatric support in relation to their self-harm more frequently (31.9% vs 14.1%). The associated clinical characteristics included behavioural disorder (OR=2.51; 95% CI, 1.62-3.90), personality disorders (OR=0.56; 95% CI, 0.33-0.97), hospital admission (OR=0.23; 95% CI, 0.16-0.33), depressive symptoms (OR=0.60; 95% CI, 0.42-0.85), anxiety symptoms (OR=2.08; 95% CI, 1.31-3.31) and self-harming to influence others (OR=2.19; 95% CI, 1.54-3.11).

CONCLUSIONS

More than half of the adolescents in the clinical sample with self-injury met DSM-5 criteria for NSSI. There are clinical and demographic characteristics which may be associated with this diagnosis.

Investigating the DSM-5 criteria for non-suicidal self-injury disorder in a community sample of adolescents

BACKGROUND

Non-suicidal self-injury (NSSI) is a serious public health concern in adolescents. In 2013, DSM-5 recognized NSSI as a distinct clinical phenomenon and made a call for more systematic research by including Non-Suicidal Self-Injury-Disorder (NSSI-D) as a condition requiring further research. Yet, few studies have examined the prevalence of NSSI-D in adolescents using the exact DSM-5 criteria. Additionally, the few studies available criticised several of the proposed diagnostic criteria and pointed out that more research is needed.

METHODS

Therefore, we examined prevalence rates of NSSI-D and investigated the four most controversial criteria (i.e., criteria A, B/C, and E) in a large community sample of adolescents (N = 2,130; 54% female; M_age = 15, SD = 1.81).

RESULTS

Our results show an overall NSSI-D prevalence rate of 7.6%, with significantly more girls (11.7%) than boys (2.9%) meeting the diagnosis. The prevalence of NSSI-D dropped to 5.5% when an alternative criterion A (i.e., ≥10 days of NSSI in the past year) was implemented. In our sample, 87% and 99% of adolescents with lifetime NSSI met criteria B and C, which clearly questions the clinical utility of these criteria for the DSM-5 diagnosis of NSSI-D. Importantly, however, although criterion E received relatively low endorsement, it significantly distinguished adolescents with and without NSSI-D from one another.

LIMITATIONS AND CONCLUSION

Although our conclusions are restricted by the cross-sectional nature of our study, these findings show that NSSI-D is common in community adolescents and offer new insights in the endorsement and clinical utility of specific NSSI-D criteria.

Nonsuicidal Self-Injury Disorder in Adolescents: Clinical Utility of the Diagnosis Using the Clinical Assessment of Nonsuicidal Self-Injury Disorder Index

Nonsuicidal self-injury disorder (NSSID) is a condition in need of further study, especially in adolescent and clinical populations where it is particularly prevalent and studies are limited. Twenty-nine clinical self-injuring adolescents were included in the study. The Clinical Assessment of Nonsuicidal Self-Injury Disorder Index (CANDI) was used to assess prevalence of NSSID. The NSSID diagnosis criteria were met by 62.1% of adolescents. The impairment or distress criterion was least often met. Criteria B and C (assessing reasons for NSSI and cognitions/emotions prior to NSSI) were confirmed by 96-100% of all participants. Adolescents with NSSI in this clinical sample had several comorbidities and high levels of psychopathology. NSSID occurred both in combination with and independently of borderline personality disorder traits as well as suicide plans and attempts. Those with NSSID had a significantly higher cutting frequency than those not meeting full NSSID criteria. Other NSSI characteristics, comorbidity, psychopathology, and trauma experiences did not differ between groups. CANDI was a feasible tool to assess NSSID in adolescents. It is important to use structured measures to assess the validity of the NSSID diagnosis across development in both community and clinical samples. The clinical utility of the NSSID diagnosis is discussed.

Nonsuicidal Self-Injury: Diagnostic Challenges And Current Perspectives

Nonsuicidal self-injury (NSSI) involves deliberate and intentional injury to body tissue that occurs in the absence of suicidal intent. Typical examples here might include self-cutting, burning, or self-hitting. Behavior of this kind is fundamentally unsettling as well as perplexing. It is also the case that self-harming behavior of any kind runs counter to a fundamental survival instinct. In the past, behaviors such as these were viewed as self-mutilation and considered to be a form of attenuated suicide. Much has changed over time, culminating in the entry of NSSI Disorder into DSM-5 as a condition in need of further study. In this review we describe the evolution of the NSSI construct and consider current issues in its diagnosis and assessment.

Increased inflammasome activity in markedly ill psychiatric patients: An explorative study

The aim of this study was to investigate inflammatory perturbations in 40 patients with severe and complex psychiatric disorders by studying the activity of the NLRP3 inflammasome, with a trans-diagnostic approach. Gene expression of CASP1, NLRP3, PYCARD, IL1B, IL1RN, TNF showed a significant increase in the patient group compared to a matched control group. Plasma levels of IL1Ra, IL-18, TNF, IL-6 and CRP were increased in the patient group. Within the patient group, increased gene expression of inflammatory markers correlated with increased disease severity. The findings support the inflammation hypothesis for markedly ill psychiatric patients across diagnostic groups.

DSM-5 personality domains as correlates of non-suicidal self-injury severity in an Italian sample of adolescent inpatients with self-destructive behaviour

To evaluate the associations between DSM-5 alternative model of personality disorder dysfunctional personality domains and the clinician's ratings of non-suicidal self-injury (NSSI) severity, a sample of consecutively admitted Italian adolescent inpatients (N = 100) were administered the Italian translations of the DSM-5 Clinician Rating Scale-NSSI (CRS-NSSI), the Personality Inventory for DSM-5 (PID-5), the Structured Clinical Interview for DSM-IV Axis II Personality Disorders, Version 2.0 (SCID-II) and the Children's Depression Inventory (CDI). Bivariate association analyses showed that PID-5 negative affectivity scores and CDI total score were significantly associated with CRS-NSSI ratings. PID-5 negative affectivity score proved to be a significant predictor of the CRS-NSSI score even when the effect of the CDI total score was held constant. Our results highlighted that specific risk factors for NSSI severity may be identified even among NSSI adolescents. © 2019 John Wiley & Sons, Ltd.

Experiencing and Resisting Nonsuicidal Self-injury Thoughts and Urges in Everyday Life

OBJECTIVE

We used a daily diary to examine (1) the frequency of three types of NSSI thoughts and urges (fleeting thoughts, persistent thoughts, and intense urges), (2) the correlates of NSSI thought and urges within and across days, (3) strategies that aid in resisting NSSI thoughts and urges, and (4) the prospective association of daily NSSI thoughts and urges with NSSI behavior over 12 months.

METHOD

Sixty adults (aged 18-35) completed a two-week daily diary and follow-ups every 3 months for one year.

RESULTS

Fleeting NSSI thoughts were reported on 48% of days, whereas persistent thoughts (11%) and intense urges (17%) were less common. Within days, earlier stress predicted more persistent NSSI thoughts, whereas earlier perceived support predicted less intense NSSI urges. Furthermore, NSSI thoughts and urges were positively associated with same-day stress and avoidant coping. Problem-focused coping was associated with greater success resisting same-day fleeting thoughts and intense urges, as well as success resisting next-day persistent thoughts. Perceived support was associated with less intense same-day urges, but also less success resisting these urges. Over the follow-up, persistent thoughts predicted less frequent NSSI, whereas intense urges predicted more frequent NSSI.

CONCLUSIONS

NSSI thoughts and urges are commonly experienced and deserve further attention.

Brain-based Classification of Negative Social Bias in Adolescents With Nonsuicidal Self-injury: Findings From Simulated Online Social Interaction

BACKGROUND

Interpersonal stress and perceived rejection have been clinically observed as common triggers of nonsuicidal self-injury (NSSI), with self-injury behavior regulating both affective and social experiences. We investigated whether the subjective interpretation of social interaction in a simulated online environment might be biased in the NSSI group, and the brain mechanisms underlying the experience.

METHODS

Thirty female adolescent patients with NSSI and thirty female age-matched controls were investigated in this case-control study. In our novel task that simulates interaction on current social media platforms, participants indicated whether they liked or disliked pictures of other players during a functional magnetic resonance imaging (fMRI) scan. Participants also viewed positive and negative feedback directed toward them by others. The task also assessed the subjective effects of the social interaction. Finally, subjects underwent a separate facial electromyography session, which measured facial expressions processing.

OUTCOMES

Behaviorally, the NSSI group showed a negative bias in processing social feedback from others. A multi-voxel pattern analysis (MVPA) identified brain regions that robustly classified NSSI subjects and controls. Regions in which mutual activity contributed to the classification included dorsomedial prefrontal cortex and subgenual anterior cingulate cortex, a region implicated in mood control. In the NSSI group, multi-voxel classification scores correlated with behavioral sensitivity to negative feedback from others. Results remained significant after controlling for medication, symptoms of depression, and symptoms of borderline personality disorder.

INTERPRETATION

This study identified behavioral and neural signatures of adolescents with NSSI during social interaction in a simulated social media environment. These findings highlight the importance of understanding social information processing in this clinical population and can potentially advance treatment approaches.

Relations of anxiety sensitivity dimensions to nonsuicidal self-injury frequency and versatility among patients with substance use disorders

OBJECTIVE

Despite the theoretical and empirical relevance of anxiety sensitivity (AS) to nonsuicidal self-injury (NSSI), few studies have investigated this association. This study examined the incremental validity of AS dimensions in NSSI frequency and versatility, above and beyond emotion dysregulation and relevant covariates (racial/ethnic background, negative affectivity). AS dimensions were expected to account for additional unique variance in NSSI outcomes.

METHOD

Participants included 204 patients (50.5% female) with substance use disorders in residential treatment.

RESULTS

In this sample, 37.2% reported a history of NSSI. The hierarchical regression models revealed a unique positive association between AS social concerns and NSSI outcomes when adjusting for model variables. In contrast, AS physical concerns were uniquely negatively associated with NSSI outcomes.

CONCLUSION

Findings provide support for AS social concerns as a vulnerability for engagement in NSSI behaviors and highlight this particular AS dimension as a potential treatment target for NSSI prevention and intervention programs.

Non-suicidal Self-Injury in Clinical Practice

Background: Non-suicidal self-injury (NSSI) among adolescents is a major public health concern and a common problem in clinical practice. The aim of this study was to examine different aspects of NSSI in a high-risk adolescent sample in clinical practice in association with personality disorders, symptoms, and coping skills to enhance the understanding of NSSI and improve treatment interventions.

Methods: In a sample of 140 adolescent inpatients treated for personality disorders, assessments were performed pre-treatment and post-treatment using a questionnaire on NSSI developed for clinical practice, the Structured Clinical Interview for DSM personality disorders, the Symptom Check List 90, and the Cognitive Emotion Regulation Questionnaire.

Results: NSSI was common (66.4%) among the inpatient adolescents. Of those without NSSI behaviour (n = 47), 10 (21.3%) started NSSI during treatment. NSSI was related to number of personality disorders and not to one specific. Participants who experienced NSSI (n = 93) reported significantly more symptoms and the negative coping strategy self-blame. They scored lower on the positive coping strategies of refocusing and reappraisal.

Conclusion: NSSI in adolescent clinical practice is common, not exclusive to borderline personality disorder and could be contagious. Reducing self-blame and enhancing positive refocusing and positive reappraisal seem important treatment targets.

Reconsidering important outcomes of the nonsuicidal self-injury disorder diagnostic criterion A

OBJECTIVE

The nonsuicidal self-injury (NSSI) disorder diagnostic criteria have been the focus of empirical study. However, Criterion A (i.e., required frequency and timeframe) has received relatively limited attention. The current study aimed to examine the relationship between past 12-month NSSI frequency and eight NSSI behavior features among individuals with past 12-month and 1-month NSSI.

METHOD

Participants were 723 undergraduate students reporting at least 1 past 12-month NSSI act and completed online questionnaires. Decision trees and structural equation model trees were utilized to examine the relationship between NSSI frequency and behavior features.

RESULTS

Results highlight several potential subgroups: high (i.e., greater than 49 acts), moderate-to-high (i.e., 19-48 acts), low-to-moderate (i.e., 7-18 acts), and low (i.e., fewer than 6 acts) frequency subgroups.

CONCLUSIONS

Findings suggest that increasing the NSSI disorder criterion A frequency cutoff or requiring at least one past month NSSI act may better demarcate individuals with more severe NSSI behavior.
