Three assessment tools for deliberate self-harm and suicide behavior: evaluation and psychopathological correlates

Emergency Department Presentations for Injuries Following Agency-Notified Child Maltreatment: Results From the Childhood Adversity and Lifetime Morbidity (CALM) Study

Child maltreatment (CM) is associated with negative health outcomes in adulthood, including deliberate self-harm (DSH), suicidal behaviours, and victimisation. It is unknown if associations extend to emergency department (ED) presentations for non-DSH related injuries. Birth cohort study data was linked to administrative health data, including ED presentations for non DSH related injuries and agency-reported and substantiated notifications for CM. Adjusted analyses (n = 6087) showed that any type of agency-reported notification for CM was significantly associated with increased odds of ED presentation for injuries (aOR = 1.57; 95% CI 1.32-1.87). In moderation analyses, women yielded significantly higher odds of notified and substantiated physical abuse, substantiated emotional abuse, and being subject to more than one type of substantiated abuse than males. ED presentations for injuries could be a proxy for risky behaviours, disguised DSH/suicidal behaviours, or physical abuse. The consistent findings in women may point to victimisation via interpersonal violence.

The relationship of the methylation status and polymorphism of glucocorticoid receptor gene (NR3C1) with attempted suicide or non-suicidal self-injury patients in schizophrenia

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

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.

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.

Daily reciprocal relations between emotion dysregulation and non-suicidal self-injury among individuals with a history of sexual assault: The influence of posttraumatic stress symptoms

INTRODUCTION

Non-suicidal self-injury (NSSI) is a serious public health concern that can be understood within an emotion dysregulation framework. The current study adds to the literature by utilizing a micro-longitudinal design and novel statistical modeling to test reciprocal associations between emotion dysregulation and NSSI, as well as the potential moderating effect of posttraumatic stress symptoms (PTSS).

METHODS

Participants were 81 individuals with a history of sexual assault and NSSI (M_age  = 33.80; 67.9% women; 80.2% white) recruited from the community who self-reported on symptoms of emotion dysregulation and NSSI thoughts/behaviors once daily for 7 days. Average compliance rate was 72.8% (SD = 31.3%) and 34 participants (42.0%) endorsed NSSI thoughts/behaviors over the course of the study.

RESULTS

Findings revealed a significant positive effect of NSSI thoughts/behaviors on subsequent abilities to regulate negative emotions. Furthermore, while results did not detect a moderating influence of baseline PTSS on the relation between emotion dysregulation and NSSI thoughts/behaviors over time, individuals with higher baseline PTSS were found to experience heightened levels of NSSI thoughts/behaviors and emotion dysregulation on average.

CONCLUSION

Information from this study may be useful for future research and intervention development focused on the intersection of NSSI, PTSS, and emotion dysregulation.

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.

Pilot study of the Collaborative Assessment and Management of Suicidality-Group

INTRODUCTION

Few evidence-based options exist for outpatient treatment of patients at risk of suicide, and to-date almost all research has focused on individually delivered psychotherapy. Group therapy for veterans at risk of suicide is a promising alternative.

METHODS

Thirty veterans receiving care at an urban Veterans Affairs Medical Center in the southern United States were randomized to either care as usual (CAU) or to CAU plus the Collaborative Assessment and Management of Suicide-Group (CAMS-G). Veterans were assessed prior to randomization to condition and at 1, 3, and 6 months post-randomization on a range of suicide-specific measures, burdensomeness, belonging, treatment satisfaction, and group cohesion.

RESULTS

Across measures and follow-up assessments, veterans in CAMS-G reported good satisfaction with the intervention, a sense of cohesion with other members of the group, and reduced symptom distress. Veterans in both conditions reported decreases in suicidal ideation and behavior, with CAMS-G participants potentially improving slightly faster.

CONCLUSION

This description of CAMS-G for veterans adds to the growing literature on suicide-specific interventions and supports the need for additional research to determine if wide-spread rollout is justifiable.

The Roles of Emotion Regulation Self-Efficacy and Emotional Avoidance in Self-Injurious Thoughts and Behaviors

Little research has examined the role of emotion regulation self-efficacy (ERSE; i.e., beliefs in one's own ability to regulate emotions) in self-injurious thoughts and behaviors (SITBs) or the factors that may underlie this relation. This study investigated whether low ERSE relates to SITBs both directly and indirectly through avoidance of negative emotions. Participants (N = 364) completed measures of ERSE, emotional avoidance, suicide attempt history, nonsuicidal self-injury (NSSI), and current severity of suicidal ideation through Amazon's Mechanical Turk. Low ERSE was significantly associated with history of suicide attempts, recent NSSI, and current severity of suicidal ideation both directly and indirectly through avoidance of negative emotions. Furthermore, low ERSE was significantly associated with a greater number of SITB types both directly and indirectly through emotional avoidance.

Evaluating the Effectiveness of a Brief Mindfulness Activity in University Students With Non-Suicidal Self-Injury Engagement

Current theoretical frameworks posit that engagement in non-suicidal self-injury (NSSI) is due to an inability to regulate one's emotions. In turn, mindfulness-based interventions have been shown to enhance emotion regulatory processes in those who engage in NSSI.

OBJECTIVE

The purpose of the present study was to determine whether a brief mindfulness activity was differentially effective at increasing state mindfulness and decreasing stress following a stress induction task in university students with versus without a history of NSSI engagement.

METHOD

The sample consisted of two groups of participants who identified as women: participants with a history of NSSI engagement (NSSI; n = 57; M_age=20.09, SD = 2.05) and participants without (no-NSSI; n = 87; M_age=20.22, SD = 1.94). All participants were asked to complete pre-intervention measures of state mindfulness and stress and were randomly assigned to either a mindfulness activity (body scan) or control task condition. Following the completion of their respective activities, a Stroop stress induction task was conducted and participants completed post-intervention measures of state mindfulness and stress.

RESULTS

Two 3-way mixed ANOVAs (Time X NSSI status X Condition) were conducted and revealed significant time by condition interactions for both state mindfulness, Wilk's Λ = .93, F(1, 140) = 10.70, p = .001, η_p² = .07, and stress, Wilk's Λ = .97, F(1, 140) = 4.21, p = .04, η_p² = .03. As such, both groups (NSSI/no-NSSI) demonstrated similar increases in state mindfulness and decreases in stress in response to the brief mindfulness activity following the stress induction. Implications for future research and practice will be discussed.HIGHLIGHTSThe brief mindfulness activity effectively increased state mindfulness.The brief mindfulness activity effectively decreased stress.Benefits were experienced similarly among both groups (NSSI/no-NSSI).

Communicating distress: suicide threats/gestures among clinical and community youth

Although self-injurious thoughts and behaviors are a global health concern, little is known about suicidal threat/gesture(s) where a person leads others to believe they want to end their lives when they have no intention to do so. This study assessed the lifetime prevalence of self-injurious thoughts and behaviors among both community adolescents (n = 1117) and in clinical youth (n = 191). Suicide threats/gestures were common among youth; 12.2% of community adolescents and 18.0% of clinical youth reporting having made a suicide threat/gesture, most commonly in the context of other self-injurious thoughts and behaviors. Across both samples, suicide threats/gestures were not uniquely associated with suicide attempts, and youth who reported suicide threats/gestures in the context of a history of self-harm or suicide plan(s) were no more likely to report a history of suicide attempt(s). Suicide threats/gestures were distinguished from suicide attempts in that they primarily fulfilled positive social functions, rather than autonomic functions. Findings suggest that suicidal threats/gestures are common in both community and clinical youth, and are not uniquely associated with suicide attempts, but rather function to communicate distress to others.

The role of sleep disturbance in the associations of borderline personality disorder symptom severity to nonsuicidal self-injury and suicide risk among patients with substance use disorders

This study sought to examine the explanatory role of sleep disturbance in the associations of borderline personality disorder (BPD) symptom severity to nonsuicidal self-injury (NSSI) and suicide risk within an at-risk sample of patients with substance use disorders (SUDs), as well as whether emotion regulation (ER) difficulties account for significant variance in the relations of sleep disturbance to NSSI and suicide risk. Patients in a residential SUD treatment facility (N = 166) completed a diagnostic interview and questionnaires. Results revealed significant indirect relations of BPD symptom severity to both NSSI frequency and suicide risk through sleep disturbance. In addition, ER difficulties accounted for significant variance in the relation of sleep disturbance to NSSI frequency (but not suicide risk). Findings highlight the relevance of sleep disturbance to the association between BPD symptoms and both suicidal and nonsuicidal self-injury and suggest the potential utility of interventions aimed at improving sleep quality among individuals with BPD pathology.

Examining momentary associations between behavioral approach system indices and nonsuicidal self-injury urges

BACKGROUND

The current study aimed to examine the concurrent and prospective relationships between the three hypothesized components of behavioral approach system (BAS) sensitivity: drive, reflecting the motivation to pursue one's desired goals; reward responsiveness, reflecting sensitivity to reward or reinforcement; and fun-seeking, reflecting the motivation for pursuing novel rewards in a spontaneous manner, and NSSI urge severity.

METHODS

A sample of 64 undergraduates with a history of repetitive NSSI completed an ecological momentary assessment protocol. During this period of time, participants reported on the BAS-constructs of drive, reward responsiveness, and fun-seeking, as well as NSSI urge severity on a momentary basis at three random intervals each day for a period of ten-days.

RESULTS

Drive and reward responsiveness, but not fun-seeking, were concurrently positively associated with NSSI urge severity. However, no associations between BAS facets and prospective NSSI urges were found.

LIMITATIONS

This study was limited by its use of single items to assess the BAS-constructs of drive, reward responsiveness, and fun-seeking.

CONCLUSIONS

Our findings indicate that feeling strongly impacted by rewards and having a strong sense of drive toward goal attainment may represent cognitive risk states that are associated with increased within-person NSSI risk. However, their lack of prospective prediction may suggest that these cognitive states are associated only on a momentary basis with NSSI urges and may not confer risk.

Testing for Sex Differences in the Nomological Network of the Triarchic Model of Psychopathy in Incarcerated Individuals

The triarchic model of psychopathy conceptualizes variants of this clinical condition as expressions of three distinct biobehavioral dispositions, termed boldness, meanness, and disinhibition. As a trait-oriented model, the triarchic model situates psychopathy within a broader nomological network of personality and psychopathology, and has proven useful for characterizing how psychopathy relates to variables in these domains as well as to biological and behavioral variables. The current study was the first to examine sex differences in the external correlates of psychopathic traits as described by the triarchic model in a prison sample. Results were generally consistent with hypotheses: The triarchic traits related to measures of personality and psychopathology in patterns that were largely consistent across sex, but with some notable differences between males and females, in the correlates of disinhibition in particular. These included stronger associations for disinhibition with substance use problems, self-harm, and staff ratings of prison misbehavior among females compared to males. Findings from this study support the value of the triarchic model for understanding similarities and differences in the nomological network of psychopathy in incarcerated males and females.

Emotional response inhibition to self-harm stimuli interacts with momentary negative affect to predict nonsuicidal self-injury urges

The current study investigated whether impaired emotional response inhibition to self-harm stimuli is a risk factor for real-time nonsuicidal self-injury (NSSI) urges. Participants were 60 university students with a history of repetitive NSSI. At baseline, participants completed an emotional stop-signal task assessing response inhibition to self-harm stimuli. Participants subsequently completed an ecological momentary assessment protocol in which they reported negative affect, urgency, and NSSI urge intensity three times daily over a ten-day period. Impaired emotional response inhibition to self-harm stimuli did not evidence a main effect on the strength of momentary NSSI urges. However, emotional response inhibition to self-harm images interacted with momentary negative affect to predict the strength of real-time NSSI urges, after adjusting for emotional response inhibition to neutral images. Our findings suggest that emotional response inhibition deficits specifically to self-harm stimuli may pose vulnerability for increased NSSI urge intensity during real-time, state-level negative affect.

Self-Critical and Self-Punishment Cognitions Differentiate Those With and Without a History of Nonsuicidal Self-Injury: An Ecological Momentary Assessment Study

The aim of this study was to examine trait, state, and temporal instability measures of self-critical and self-punishment cognitions to evaluate their respective roles in nonsuicidal self-injury (NSSI). Participants were university students with a history of NSSI (n = 64) and those with no history of NSSI (n = 59). At baseline, participants completed measures assessing history of NSSI behavior, as well as trait measures of self-criticism and self-punishment. After completion of baseline procedures, participants subsequently participated in a 10-day ecological momentary assessment protocol in which self-critical and self-punishment cognitions were assessed in real time three times daily. Employing bivariate and multivariate frameworks, our results demonstrate that both trait and state levels of self-critical and self-punishment cognitions robustly differentiate between young adults with and without a lifetime history of NSSI. The present results also confirm that the temporal instability of these cognitive states also meaningfully differentiate between groups, such that those who exhibit greater fluctuations in these cognitive states are more likely to have a history of NSSI. The current findings suggest that trait, state, and temporal instability of negative self-focused cognitions may be vulnerability factors for engagement in NSSI.

Unusual (self-)injuries in a case of hanging

A 41-year-old man was found by his wife in an atypical hanging situation in their apartment. As there was a known previous psychiatric illness and a history of suicide attempts, the investigative authorities assumed this case was a suicide. However, the autopsy revealed numerous findings that are unusual for a suicidal atypical hanging, including numerous cuts on the face, the arms and the penis. According to his wife, the deceased suffered from Asperger's syndrome with auto-aggressive behavior. He had allegedly injured himself with household scissors in the days before his death and had hit himself numerous times in the face the night before his death. His wife also revealed that she would injure him with scissors at his request. Even though the observed injury pattern in this case contradicted a self-infliction, the information given by the wife about the chronology of the occurrence of injuries could be reconciled with the findings of the immunohistochemical estimation of wound age. The circumstances that led to the hanging remained unresolved.

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.

The role of reward sensitivity and childhood maltreatment in predicting nonsuicidal self-injury

OBJECTIVE

Findings from prior research on reward sensitivity in nonsuicidal self-injury (NSSI) have been mixed. Childhood maltreatment is an independent risk factor for NSSI and for hyposensitivity to rewards. This study aimed to disentangle the role of reward sensitivity as a predictor of NSSI for those with an elevated severity of childhood maltreatment.

METHOD

In a diverse undergraduate sample (N = 586), trait reward sensitivity (i.e., behavioral approach system subscales) and the severity of maltreatment were assessed as predictors of a lifetime history of NSSI. In a subset of this sample (n = 51), predictors of NSSI urge intensity were measured using ecological momentary assessment.

RESULTS

Individuals with elevated maltreatment who reported less positive responsiveness to rewards were more likely to have a lifetime history of NSSI. Those with elevated maltreatment who reported a lower likelihood to approach rewards experienced more intense NSSI urges across the ten-day observation period. However, those with elevated maltreatment who reported a greater likelihood to approach rewards experienced less intense NSSI urges.

CONCLUSIONS

The role of reward sensitivity as a cognitive risk factor for NSSI varies depending on childhood maltreatment history. Findings indicate that, for those with elevated maltreatment, hypersensitivity to approaching rewards may decrease risk for NSSI urges.

Predicting engagement in nonsuicidal self-injury (NSSI) over the course of 12 months: the roles of borderline personality disorder pathology and emotional consequences of NSSI

BACKGROUND

Despite theories that negative reinforcement in the form of relief from negative emotions maintains nonsuicidal self-injury (NSSI), no studies have examined the extent to which specific emotional consequences of NSSI predict the maintenance of NSSI over time or explain the greater risk for NSSI found among individuals with borderline personality disorder (BPD) pathology. This study examined whether specific emotional consequences of NSSI relate to the continuance of NSSI behavior over a 12-month period and explain the relation of baseline BPD pathology to future NSSI.

METHODS

Participants with a history of recent repeated NSSI (N = 84) completed baseline measures of BPD pathology, NSSI, and the emotional antecedents and consequences of NSSI, including self-conscious emotions, undifferentiated negative affect, anger, emptiness, sadness, and anxiety; follow-up data on NSSI were collected every three months for one year.

RESULTS

Of the emotional consequences of NSSI examined here, only self-conscious emotions significantly predicted the presence and frequency of NSSI during the 12-month follow-up period. Likewise, whereas BPD pathology was not directly associated with later NSSI, both overall BPD pathology and the specific BPD feature of identity problems were indirectly related to the presence of 12-month NSSI through the greater frequency of post-NSSI self-conscious emotions.

LIMITATIONS

Emotional consequences of NSSI were assessed using a retrospective self-report measure. Only frequency, and not intensity, of emotions before and after NSSI were assessed.

CONCLUSIONS

Results suggest a distinct role of post-NSSI self-conscious emotions in the maintenance of NSSI among individuals with and without BPD pathology.

The psychometric properties and clinical utility of the Norwegian versions of the deliberate self-harm inventory and the inventory of statements about self-injury

Deliberate self-harm (DSH) is a widespread transdiagnostic health problem with increasing prevalence among adolescences, and young adults. It is therefore essential to effectively chart the epidemiology of DSH, as well as to assess the efficacy of interventions designed to modify this behavior. The aim was to translate and analyze the psychometric properties of the Norwegian versions of two instruments designed to assess DSH: the Deliberate Self-harm Inventory (DSHI) and the Inventory of Statements About Self-Injury (ISAS), as well as to assess the prevalence of DSH within a nonclinical Norwegian adult population. Of the 402 participants who completed a questionnaire packet comprising the DSHI, ISAS, general questions about DSH, and other related measures, 30.6% reported some form of DSH. Those with a history of DSH reported greater difficulties with emotion regulation than those without. Participants with and without a history of DSH did not differ in unrelated constructs, including social desirability. The frequency of specific DSH behaviors was in accordance with previous research, with cutting being the most frequent. The factor structure of DSH functions in the Norwegian ISAS was generally comparable to the factor structure of the English version. Overall, results indicate that: a) the Norwegian versions of the DSHI and ISAS behave as expected and in accordance with prior research in other languages and other populations, and b) both the DSHI and ISAS have high internal consistency and adequate construct, convergent, and discriminant validity, and may be applied to evaluate DSH in adult Norwegian populations.

Self-Stigma Toward Nonsuicidal Self-Injury: An Examination of Implicit and Explicit Attitudes

OBJECTIVE

Evidence suggests that individuals without a history of nonsuicidal self-injury (NSSI) are likely to view NSSI as a stigmatized behavior. However, there is limited evidence evaluating the presence of self-stigma among individuals who have engaged in NSSI.

METHODS

We recruited a university sample (n = 351) and employed implicit and explicit measures to examine the degree of stigmatization toward those with NSSI scarring, as compared to nonintentional disfigurement (i.e., accidental scarring) and to tattoos (i.e., a culturally sanctioned form of intentional tissue alteration). We examined the extent to which bias is related to indicators of NSSI severity among those with a history of NSSI.

RESULTS

We provide evidence that negative biases toward NSSI may represent the effects of self-stigma. However, findings suggest that biases were generally attenuated among participants with a history of NSSI as compared to those without. Participants who had lower levels of NSSI explicit bias were more likely to have a history of more severe engagement in NSSI; however, no significant relationships were found between implicit bias and NSSI severity indicators.

CONCLUSIONS

We present a theoretical rationale for attenuated biases among individuals with a history of NSSI and discuss implications of this research for NSSI recovery.

Expanding our understanding of the relationship between nonsuicidal self-injury and suicide attempts: The roles of emotion regulation self-efficacy and the acquired capability for suicide

OBJECTIVE

Although past literature has emphasized the role of acquired capability in the relationship between nonsuicidal self-injury (NSSI) and suicide attempts, support for the indirect relationship of NSSI to suicide attempts through acquired capability is limited. Thus, research examining other factors that may underlie this relationship is needed. Across two studies, this research examined the indirect relationships of NSSI frequency to suicide attempts through both acquired capability and emotion regulation self-efficacy (ERSE).

METHOD

Two large samples of adults (one nationwide community sample and one clinical sample of patients with substance use disorders) completed questionnaires and/or interviews.

RESULTS

Results revealed significant indirect relationships of NSSI frequency to lifetime suicide attempts through ERSE, but not acquired capability, within both samples.

CONCLUSIONS

Results highlight the relevance of ERSE to both suicide attempts and the NSSI-suicide attempt relationship, and suggest the potential utility of interventions aimed at increasing ERSE among individuals with repeated NSSI.

Attachment-Related Representations and Suicidal Ideations in Nonsuicidal Self-Injury Adolescents with and without Suicide Attempts: A Pilot Study

OBJECTIVES

Consistent with the debate surrounding the association between nonsuicidal self-injury (NSSI), suicidal intent, and suicidal behavior, and between NSSI and dysregulation processes, we attempted to analyze suicide intent and emotion dysregulation in NSSI adolescents, in the framework of the attachment representations and exploring these clues of emotion dysregulation characteristics of insecure attachment. Furthermore, we intended to focus on these attachment-related segregated systems regarding death and suicidal ideations, to explore how differently they would characterize self-injuring adolescents with and without suicide attempts.

METHODS

Thirty-four NSSI inpatient adolescents, 17 with suicide attempts, 17 without suicide attempts, and 17 healthy controls (age 11-17) were assessed using Adult Attachment Projective, which allows for the classification of attachment status and related emotion dysregulation and segregated systems.

RESULTS

The majority of the NSSI group with and without suicide attempts showed unresolved (disorganized) attachment-related representations and clues of damaged reflective functions, whereas only the NSSI with suicide attempts showed clues of impaired interpersonal relationships. The two clinical groups used words expressing suicidal intent, whereas the healthy group did not.

CONCLUSIONS

Therapists are encouraged not to underestimate suicidal ideation in NSSI regardless of whether or not they have already attempted suicide.

Association of Social Media Use and High-Risk Behaviors in Adolescents: Cross-Sectional Study

BACKGROUND

Previous studies have demonstrated the prevalence of social media use and identified the presence of high-risk behaviors among adolescents, including self-harm and sharing of sexually explicit messages.

OBJECTIVE

This study aimed to identify patterns in the amount of time spent on social media by adolescents who engage in high-risk behavior and the extent to which they use social media as a platform for sharing such behaviors.

METHODS

This was a descriptive cross-sectional study of 179 adolescents seen in a pediatric clinic at an urban medical center. We used an anonymous self-report survey to obtain demographic characteristics, rates of self-harm thoughts and behaviors, sharing of sexually explicit messages, and social media use as determined by total hours spent on social media per day and the number of applications used.

RESULTS

Most adolescents reported spending 3 to 5 hours on social media each day and using 3 or more social media applications. Almost 1 in 8 (22/179, 12.3%) adolescents self-reported having ever engaged in self-injury with a mean age of onset of 11.8 years. Over a quarter (49/179, 27.4%) of adolescents reported sharing sexually explicit messages. Relative risk of engaging in self-injury and or sharing sexually explicit messages increased with the use of 4 or more social media applications (1.66; CI 1.11-2.48).

CONCLUSIONS

Results show a relationship between the number of social media applications used and increased rates of high-risk behaviors. We identified relevant risk factors that clinicians can use to screen for high-risk behavior and parents can monitor to encourage education about healthy online practices.

Methods Matter: Nonsuicidal Self-Injury in the Form of Cutting is Uniquely Associated with Suicide Attempt Severity in Patients with Substance Use Disorders

OBJECTIVE

Despite the robust relation between nonsuicidal self-injury (NSSI) and suicidal behaviors, there is considerable heterogeneity in NSSI characteristics that may have implications for the strength of the NSSI-suicide attempt relation. Past research highlights the relevance of both more severe NSSI methods and NSSI in the form of cutting in particular to suicide attempts. To further explore the relations of specific NSSI methods to suicide attempts, this study examined relations between different NSSI methods (i.e., those involving cutting, burning, blunt force, or resulting in minor tissue damage) and both overall suicide attempts and two indicators of suicide attempt severity (attempts requiring medical attention and nonambivalent attempts) in 203 substance-dependent patients in residential treatment.

METHOD

Participants were administered questionnaires and semistructured interviews assessing the variables of interest.

RESULTS

Cutting was the only NSSI method to demonstrate significant relations with overall suicide attempts, nonambivalent suicide attempts, and suicide attempts requiring medical attention. Results remained when considering relevant covariates.

CONCLUSION

Results highlight an important link between NSSI methods involving cutting and suicide attempts among patients with substance use disorders. Findings also highlight the importance of more fine-grained characterizations of NSSI subgroups.

Functions of Non-Suicidal Self-Injury in Late Adolescence: A Latent Class Analysis

This study employed latent class analysis utilizing an array of features of non-suicidal self-injury (NSSI) in order to identify distinct subgroups of self-injurers. Participants were 359 undergraduates with NSSI history. Indicator variables were lifetime and last year frequency rates, number of methods, scarring, pain during self-injury, and functions of NSSI. Analyses yielded mild/experimental NSSI, moderate NSSI, moderate multiple functions NSSI, and severe NSSI groups, endorsing low, moderate, moderate multiple functions, and high frequencies of self-injury and presence of functions, respectively. Following class assignment, groups differed on self-esteem, social support and belongingness, internalizing symptoms, suicidal ideation and behaviors, and additional NSSI constructs. These subtype analyses emphasize matching phenotypes of NSSI to specific interventions considering dimensions of clinical functioning.

Does State Dissociation Mediate the Relation Between Alcohol Intoxication and Deliberate Self-Harm?

Research supports the notion that alcohol intoxication is a risk factor for deliberate self-harm (DSH). However, the underlying mechanisms for this relationship are poorly understood. We aimed to determine whether alcohol-induced dissociation mediated alcohol's effects on DSH. We used data from a dose-response study of alcohol intoxication and DSH to test the proposed model. Participants were assigned to reach target blood alcohol concentrations (BAC) ranging from 0.00% through 0.10% and then completed a behavioral measure of DSH. Dissociation was assessed using the Alcohol Dissociative Experiences Scale. BAC predicted both dissociation and DSH, but dissociation did not predict DSH. Although research on clinical populations suggests dissociation is related to DSH, our findings suggest dissociation does not mediate the effects of alcohol on self-harm.

Comparing the Triarchic and Five-Factor Trait Models: Relations With Psychopathy and Other Clinical Criteria in an Incarcerated Offender Sample

This study compared how normative personality dimensions of the Five-Factor Model (FFM) and neurobehavioral traits of the triarchic model relate to psychopathic tendencies and clinical outcomes in an incarcerated sample of 277 Italian male offenders. Associations between triarchic model traits, measured using the TriPM and the FFM dimensions, measured using the NEO-FFI, were consistent with prior studies. Scores on the TriPM, particularly the Disinhibition scale, were associated with substance abuse and self-harm behavior over and above the presence of psychopathy, and beyond the personality dimensions indexed by the NEO-FFI. By contrast, the Neuroticism and Extraversion scales showed incremental validity, over and above psychopathy and TriPM scores, in predicting depressive tendencies. Lastly, both NEO-FFI and TriPM scales contributed to prediction of staff ratings of behavior in prison and prognosis for release, above and beyond psychopathy. These findings highlight potential advantages of the FFM and triarchic trait models for predicting clinical outcomes.

Examining Sexual Assault Victimization and Loneliness as Risk Factors Associated With Nonlethal Self-Harm Behaviors in Female College Students: Is It Important to Control for Concomitant Suicidal Behaviors (and Vice Versa)?

The present study examined sexual assault victimization and loneliness as predictors of self-harm behaviors in a sample of 224 female college students. Results from conducting regression analysis indicated that both sexual assault victimization and loneliness were unique and significant predictors of self-harm behaviors. This pattern remained even after controlling for concomitant suicidal behaviors. Interestingly, in a post hoc analysis predicting suicidal behaviors, it was found that loneliness, but not sexual assault victimization, was the only unique and significant predictor after controlling for self-harm behaviors. Some implications of the present findings for understanding self-harm behaviors in female college students and the importance of controlling for suicidal behaviors in studies of self-harm behaviors (and vice versa) are discussed.

Examining the link between prior suicidality and subsequent suicidal ideation among high-risk US military service members

BACKGROUND

Research is needed to identify the factors that explain the link between prior and future suicidality. This study evaluated possible mediators of the relationship between: (1) the severity of prior suicidality and (2) suicidal ideation severity at 3-month follow-up among a sample of high-risk military personnel.

METHODS

US military service members referred to or seeking care for suicide risk (N = 624) completed self-report psychiatric domain measures and a clinician interview assessing prior suicidality severity at baseline. Three months later, participants completed a self-report measure of suicidal ideation severity. Three separate percentile bootstrap mediation models were used to examine psychiatric factors (i.e. alcohol abuse, anxiety sensitivity, hopelessness, insomnia, posttraumatic stress symptoms, suicidal ideation, and thwarted belongingness) as parallel mediators of the relationship between prior suicidality severity (specifically, suicidal ideation, suicide attempt, and overall suicidality - i.e. ideation/attempt severity combined) at baseline and suicidal ideation severity at follow-up.

RESULTS

Hopelessness, specifically, and the total effect of all mediators, each significantly accounted for the relationship between prior suicidality severity and subsequent ideation severity across models. In the models with attempt severity and overall suicidality severity as predictors, thwarted belongingness was also a significant mediator.

CONCLUSIONS

Hopelessness, thwarted belongingness, and overall severity of psychiatric indices may explain the relationship between prior suicidality severity and future suicidal ideation severity among service members at elevated suicide risk. Research is needed to replicate these findings and examine other possible mediators.

Frustration with feeling: Latent classes of non-suicidal self-injury and emotion regulation difficulties

Although emotion regulation has been identified as a key function of non-suicidal self-injury (NSSI), it is unclear how specific indices of emotion regulation are associated with particular NSSI methods as markers of risk. This study used latent class analysis (LCA) to identify subgroups of individuals who engage in NSSI and their patterns of emotional regulation difficulties. Undergraduate students in the southeastern United States (N = 326) completed an online survey. LCA was used to identify subgroups of individuals engaging in NSSI and their associated emotion regulation difficulties. These subgroups were then compared across a variety of behavioral health outcomes (e.g. impulsive behavior, disordered eating, problematic alcohol use, suicide attempt history) to characterize specific risk profiles. The LCA revealed four subgroups who engage in NSSI and have specific emotion regulation difficulties. These subgroups were differentially associated with behavioral health outcomes, including suicide risk, disordered eating, and impulsive behavior. Results of this research could aid in clinical identification of at-risk individuals.

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.

Investigating the reliability of suicide attempt history reporting across five measures: A study of US military service members at risk of suicide

OBJECTIVE

Utilizing a sample of military service members at risk of suicide, this study aimed to: (a) identify patterns of suicide attempt (SA) history reporting across five measures and (b) evaluate whether consistent SA reporters (i.e., individuals who consistently report an SA history across measures) differ from inconsistent SA reporters on other clinical severity indices.

METHOD

Participants (N = 984) completed five validated SA history measures and self-report psychiatric symptom measures.

RESULTS

Of the sample, 35.4% inconsistently responded to SA history measures. Inconsistent reporters disclosed more severe suicide threat histories than consistent reporters. On all other clinical severity indices, inconsistent reporters evinced either less severe or comparable symptom levels.

CONCLUSIONS

A nontrivial portion of service members may respond inconsistently to different assessments of SA history. Research is needed to identify factors that account for inconsistent SA history reporting and to improve the accuracy of SA history assessments among military personnel.

The stigmatization of nonsuicidal self-injury

OBJECTIVE

Despite the high prevalence of nonsuicidal self-injury (NSSI), no research has systematically studied the occurrence and effects of stigmatization by others towards NSSI scarring.

METHODS

The current study measured implicit and explicit attitudes among undergraduates towards NSSI scarring using the implicit association test and questionnaires to compare implicit and explicit biases towards NSSI with biases towards tattoos, a culturally sanctioned form of self-determined marking, as well as nonintentional disfigurement.

RESULTS

Our study demonstrated strong negative implicit and explicit biases towards NSSI when comparing NSSI to tattoos and nonintentional disfigurement.

CONCLUSIONS

Results extend previous research describing stigma towards mental illness and suggest a large negative bias towards NSSI. The importance of studying how stigma affects those who bear scarring from NSSI is discussed.

Preliminary evaluation of an intensive integrated individual and family therapy model for self-harming adolescents

BACKGROUND

To investigate the outcome of an integrated individual and family therapy (Intensive Contextual Treatment: ICT) in terms of reducing suffering and increasing functional adjustment among self-harming and/or suicidal adolescents with high symptom loads and their families.

METHODS

Forty-nine self-harming and/or suicidal adolescents, Mage = 14.6, of predominantly Swedish origin and female gender (85.7%) participated with their parents. The study had a within group design with repeated measures at pre- and post-treatment, as well as six- and twelve-months follow-ups. Self-reports were used for the main outcomes; self-harm rates, suicide attempts, parent-reported days of inpatient/institutional care, internalized and externalized symptoms, perceived stress, emotion regulation, school hours and adjustment. Secondary outcomes were levels of reported expressed emotions within family dyads, as well as parental anxiety, depression and stress.

RESULTS

From pre- to post-assessment, the adolescents reported significant reductions of self-harm (p = .001, d = 0.54) and suicide attempts (p < .0001, d = 1.38). Parent-reported days of inpatient/institutional care were reduced, as well as parent- and adolescent-reported internalizing and externalizing symptoms. Furthermore, school attendance and adjustment were improved, and the adolescents reported experiencing less criticism while parents reported less emotional over-involvement. The results were maintained at follow-ups.

CONCLUSIONS

The adolescents and the parents reported improvements for the main outcomes. This treatment appears promising in keeping the families in treatment and out of hospital, suggesting that an integrative approach may be beneficial and feasible for this group.

TRIAL REGISTRATION

Substance Misuse Is Associated With Increased Psychiatric Severity Among Treatment-Seeking Individuals With Borderline Personality Disorder

Despite high prevalence rates of concurrent borderline personality disorder (BPD) and substance use disorders (SUDs), little is known about the impact of substance misuse on the presentation of BPD. Sixty-five individuals with BPD were assessed at intake and at 3- and 6-month follow-up. Assessment included validated instruments such as the Addiction Severity Index and the Revised Symptom Checklist (SCL-90-R). Over half (58.5%) of individuals entering treatment were currently misusing substances. Substance misuse was associated with more legal and employment problems, greater mood disturbance, impulsivity, and psychiatric severity, including almost all SCL-90-R subscales. For the majority of patients (58%), there was little change in substance misuse post-treatment. The high prevalence of substance misuse and its association with psychiatric severity among individuals with BPD suggest that substance misuse should be a targeted behavior during treatment, and further specialized interventions are needed for individuals with comorbid BPD and SUD.

Assessing the predictability of self-harm in a high-risk adult prisoner population: a prospective cohort study

BACKGROUND

Prisoners are at increased risk of self-harm and when either intent is expressed, or an act of self-harm carried out, prisoners in the UK are subject to self-harm/suicide monitoring (referred to as "open ACCT" monitoring). However, there is a paucity of validated instruments to identify risk of self-harm in prisoner populations. In response to the need to support prison staff to determine who is at increased risk of self-harm or repeat self-harm, the aim of this study was to determine whether any pre-existing, standardised instruments could usefully identify future self-harm events in prisoners undergoing ACCT monitoring.

METHODS

A multi-stage prospective cohort study was conducted, where the Prison Screening Questionnaire (PriSnQuest), a modified Borderline Symptom List-23 (BSL-23), Self-Harm Inventory (SHI), Patient Health Questionnaire-9 (PHQ-9) and Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) instruments were administered to prisoners aged 18 and above, who were judged to be at an increased risk of self-harm (on open ACCT monitoring) during the recruitment phase. A 6-month follow-up determined self-harm occurrence since baseline, and Area-Under-the-Curve (AUC) analysis examined the ability of the instruments to predict future self-harm.

RESULTS

Prison records established that 29.1% self-harmed during the follow up period, involving a total of 423 self-harm events reported from 126 individuals, followed up for 66,789 prisoner days (median 167 days; IQR 71-207.5 days). This translated to an 'event incidence' of 6.33 per 1000 prisoner days of those who had been placed upon an ACCT, or 'prisoner incidence' of 1.89 per 1000 days, with considerable variation for both gender and participating prisons. None of the summary scores derived from the selected instruments showed a meaningful ability to predict self-harm, however, exploratory logistic regression analysis of individual background and instrument items revealed gender-specific item sets which were statistically significant in predicting future self-harm.

CONCLUSIONS

Prospective self-harm was not predicted by any of the pre-existing instruments that were under consideration. Exploratory logistic regression analysis did reveal gender-specific item sets, producing predictive algorithms which were statistically significant in predicting future self-harm; however, the operational functionality of these item sets may be limited.

Is the association of deliberate self-harm with emotional relief stable or dependent on emotional context?

BACKGROUND AND OBJECTIVES

Despite strong support for the role of emotional relief in deliberate self-harm (DSH), no research has examined the impact of emotional distress on the strength of the DSH-relief association. Thus, it remains unclear whether the association of DSH with emotional relief is stable across emotional contexts or context-dependent. This study aimed to examine if the implicit DSH-relief association is stronger in the context of emotional distress (relative to a neutral emotional context).

METHODS

Young adult women with (n = 60) and without (n = 60) a history of recent recurrent DSH were randomly assigned to complete a novel version of the Implicit Association Test (IAT) assessing the DSH-relief association at baseline (following an initial neutral emotion induction) and again following either a neutral or negative (i.e., social rejection) emotion induction.

RESULTS

Consistent with hypotheses, the DSH-relief association was stronger among women with recent recurrent DSH (vs. those without DSH) at baseline. Contrary to hypotheses, however, whereas the DSH-relief association remained stable following both the neutral and negative emotion inductions among participants with DSH, it became stronger across both conditions for participants without DSH.

LIMITATIONS

The use of a community sample of young adult women may limit generalizability to other relevant populations (e.g., clinical populations, young men, adolescents). Additionally, the negative emotion induction may not have been powerful enough to affect the strength of the learned DSH-relief association among individuals with a repeated history of DSH.

CONCLUSIONS

Findings suggest that the repeated use of DSH to bring about emotional relief may engender associations of DSH with relief that are relatively insensitive to emotional context.

The Role of Distal Minority Stress and Internalized Transnegativity in Suicidal Ideation and Nonsuicidal Self-Injury Among Transgender Adults

Transgender people are at elevated risk for nonsuicidal self-injury (NSSI) and suicidal ideation compared to the general population. Transgender (trans) refers to a diverse group of people who experience incongruence between their gender identity and sex assigned at birth. The present study is guided by the minority stress model and the psychological mediation framework, which postulate that sexual minority groups experience elevated stress as a result of anti-minority prejudice, contributing to negative mental health outcomes. This study utilized these theories to investigate the role of internalized transnegativity-internalization of negative societal attitudes about one's trans identity-in the relationships of distal trans stress to suicidal ideation and NSSI. A U.S. national sample of trans adults (N = 237) completed a battery of online measures. Structural equation modeling (SEM) was used to compare models with mediation and moderation effects. Results suggested that internalized transnegativity acts as both a mediator and a moderator in the relationship between distal trans stress and suicidal ideation. Log likelihood comparisons suggested moderation models had the superior fit for these data. Results suggest that clinical interventions should directly target individuals' internalized transnegativity as well as societal-level transnegativity.

Identifying the relative importance of non-suicidal self-injury features in classifying suicidal ideation, plans, and behavior using exploratory data mining

Individuals with a history of non-suicidal self-injury (NSSI) are at alarmingly high risk for suicidal ideation (SI), planning (SP), and attempts (SA). Given these findings, research has begun to evaluate the features of this multi-faceted behavior that may be most important to assess when quantifying risk for SI, SP, and SA. However, no studies have examined the wide range of NSSI characteristics simultaneously when determining which NSSI features are most salient to suicide risk. The current study utilized three exploratory data mining techniques (elastic net regression, decision trees, random forests) to address these gaps in the literature. Undergraduates with a history of NSSI (N = 359) were administered measures assessing demographic variables, depression, and 58 NSSI characteristics (e.g., methods, frequency, functions, locations, scarring) as well as current SI, current SP, and SA history. Results suggested that depressive symptoms and the anti-suicide function of NSSI were the most important features for predicting SI and SP. The most important features in predicting SA were the anti-suicide function of NSSI, NSSI-related medical treatment, and NSSI scarring. Overall, results suggest that NSSI functions, scarring, and medical lethality may be more important to assess than commonly regarded NSSI severity indices when ascertaining suicide risk.

Restrictive eating and nonsuicidal self-injury in a nonclinical sample: Co-occurrence and associations with emotion dysregulation and interpersonal problems

Disordered eating frequently co-occurs with nonsuicidal self-injury (NSSI), and evidence suggests that the co-occurrence of these behaviors is associated with heightened emotion dysregulation. However, little is known about the relationship between restrictive eating and NSSI, and the significance of their co-occurrence. This study examined cross-sectional associations between self-reported restrictive eating, NSSI, and putative mechanisms of emotion regulation and interpersonal problems in a non-clinical sample of undergraduate students (N = 98, 80.6% female), using the Dietary Restriction Screener (Haynos & Fruzzetti, 2015), Deliberate Self-Harm Inventory (Gratz, 2001), Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2006), and Inventory of Interpersonal Problems-Personality Disorders-25 (Kim & Pilkonis, 1999). Hierarchical logistic regression analyses indicated that restrictive eating was associated with NSSI above and beyond the influence of binge eating, purging, and relevant covariates (B = 2.04, p < 0.001). In addition, multivariate analyses of variance revealed that the co-occurrence of restrictive eating and NSSI was associated with greater difficulties accessing and implementing effective, rather than impulsive, emotion regulation strategies when distressed than either behavior alone (p < 0.001). Findings highlight the seriousness of restrictive eating even within a nonclinical sample, as it is associated with heightened probability of NSSI and clinical severity among those who engage in co-morbid NSSI. Healthcare providers are encouraged to screen for NSSI among individuals with restrictive eating. In addition, a focus on improving emotion regulation and interpersonal skills may enhance prevention and intervention efforts for individuals with co-occurring restrictive eating and NSSI behaviors.

Socio-Demographic and Mental Health Profile of Admitted Cases of Self-Inflicted Harm in the US Population

Self-inflicted harm (SIH) has a substantial lifetime prevalence, it is associated with tremendous costs, and its rate is increasing on a national scale. To examine the characteristics of those admitted for SIH in the US and to investigate the factors that potentially modify the methods used for SIH. This was a retrospective analysis of admitted cases of SIH including suicide attempts between 2007 and 2012 using the National Trauma Data Bank. We included a total of 204,633 cases admitted for SIH. Our participants were 75.1% males. Those aged 15-24 (21%), 25-34 (22%), 35-44 (19%), 45-54 (19%), and 55-64 (10%) years comprised the largest age groups among our cases-70.8%, 11.5%, 11.1%, and 6.6% were, respectively, Caucasians, Hispanics, Blacks, and Asian/Others. Analyses of the SIH methods revealed that Blacks were less likely to self-poison [Odds Ratio (OR): 0.78] compared to Whites, whereas individuals with psychiatric disorders or substance abuse carried 2.5 and 2.0-fold higher risk, respectively. Blacks were also less likely to use anoxic methods (OR: 0.69), whereas patients with psychiatric disorders or substance abuse carried 1.5-fold higher risk. Being Black, Hispanic, and Asian (OR: 0.58, 0.55, and 0.55, respectively) as well as having psychiatric disorders (OR: 0.80) were associated with lower risks of using firearms, whereas its risk was increased with increasing age. Blacks (OR: 0.77) were less likely to cut or pierce in contrast to Hispanics (OR: 1.4), Asians/Others (OR: 1.29), and those with psychiatric disorders (2.5-fold higher risk) or drug abuse (2-fold higher risk). Blacks (OR: 1.11), Hispanics (OR: 1.13), and Asians/Others (OR: 1.57) were more likely to jump from high places, whereas those with substance abuse were less likely (OR: 0.77). Among patients admitted for SIH, males, those aged 15-64 years, and Whites comprised the largest sex, age, and racial/ethnic groups, respectively. We also found that several factors including race/ethnicity, gender, age, and having concurrent psychiatric or drug abuse disorders can potentially influence the methods used for SIH.
