Understanding the subtypes of non-suicidal self-injury: A new conceptual framework based on a systematic review

Non-suicidal self-injury (NSSI) is a significant public health problem, but there is no consistent evidence of its risk factors. One possibility is that there are subtypes NSSI that have different risk factors and clinical symptoms. In this review we evaluated the evidence of subtypes to determine if there were consistent subtypes of NSSI that emerged across studies. Four databases (Medline; Embase; PsycINFO; Web of Science) were searched to identify studies that used data-driven approaches and were published before November 9, 2022. There were 21 studies with 23 unique samples for review. Most of the included studies used NSSI symptoms or personal characteristics as the subtyping indicators, revealing 2-5 subtypes of NSSI. Variations in subtyping indicators, sample characteristics, and statistical methods may have contributed to the inconsistent number and characteristics of subtypes across studies. A new conceptual framework is proposed to integrate these diverse findings, highlighting the important roles of NSSI function and psychological pain in differentiating NSSI subtypes. This framework sheds light on the differences among self-injurers and offers insights for future endeavors to address the complexities of NSSI.

Prevalence, correlates and common methods of non-suicidal self-injury in South Asia: a systematic review

INTRODUCTION

The dynamics of self-harm vary substantially around the world, yet it is severely under-researched outside of a small number of high-income 'Western' countries. South Asia is disproportionately impacted by suicide, yet we know less about non-suicidal self-injury (NSSI) in the region.

OBJECTIVE

To review and summarise evidence on the prevalence, correlates and common methods of NSSI in South Asia.

METHODS

We searched Medline, Embase and PsycINFO for the period 1 January 2000 to 31 August 2023, for peer-reviewed observational studies. A total of 11 studies from eight South Asian countries that reported prevalence and/or correlates of NSSI were included in this review. We assessed the quality of the studies using the Study Quality Assessment Tools for Observational Cohort and Cross-Sectional Studies. We used meta-regression to describe the sources of heterogeneity. Abstracted data were summarised using thematic synthesis.

RESULTS

For non-clinical populations, the 12-month prevalence of NSSI ranged from 3.2% to 44.8%, and the lifetime prevalence ranged from 21% to 33%. For clinical populations, the 12-month prevalence of NSSI ranged from 5% to 16.4%, while the lifetime prevalence ranged from 2% to 27%. Male sex, unemployment, financial stress, history of suicidal behaviour and depression were associated with a higher risk of NSSI. Better access to counselling services, higher self-esteem and self-knowledge were associated with a lower risk of NSSI.

CONCLUSION

The burden of NSSI in South Asia appears to be high in both clinical and non-clinical populations. Further research, especially with general population samples, is needed to build evidence on the epidemiology, context and meaning of NSSI in South Asia to inform the design of context-specific interventions.

Brief Interventions for Self-injurious Thoughts and Behaviors in Young People: A Systematic Review

Rates of self-injurious thoughts and behaviors (SITBs) increase sharply across adolescence and remain high in young adulthood. Across 50 years of research, existing interventions for SITBs remain ineffective and inaccessible for many young people in particular need of mental healthcare. Briefer intervention options may increase access to care. However, many traditional interventions for SITBs take 6 months or more to complete-making it difficult for providers to target SITBs under real-world time constraints. The present review (1) identifies and (2) summarizes evaluations of brief psychosocial interventions for SITBs in young people, ages 10-24 years. We conducted searches for randomized and quasi-experimental trials conducted in the past 50 years that evaluated effects of "brief interventions" (i.e., not exceeding 240 min, or four 60-min sessions in total length) on SITBs in young people. Twenty-six articles were identified for inclusion, yielding a total of 23 brief interventions. Across all trials, results are mixed; only six interventions reported any positive intervention effect on at least one SITB outcome, and only one intervention was identified as "probably efficacious" per standard criteria for evidence-based status. While brief interventions for SITBs exist, future research must determine if, how, and when these interventions should be disseminated.

Effects of an Aboriginal and Torres Strait Islander Mental Health First Aid training programme for non-suicidal self-injury on stigmatising attitudes, confidence in ability to assist, and intended and actual assisting actions: an uncontrolled trial with precourse and postcourse measurement and 6-month follow-up

OBJECTIVES

Non-suicidal self-injury (NSSI) is a complex issue affecting Aboriginal and/or Torres Strait Islander Peoples in Australia. We evaluated the effects of an Aboriginal and Torres Strait Islander Mental Health First Aid (AMHFA) training course on assisting an Aboriginal and/or Torres Strait Islander person engaging in NSSI, including the effects on stigmatising attitudes, confidence in ability to assist, and intended and actual assisting actions.

DESIGN

Uncontrolled trial with precourse and postcourse measurement (n=49) and 6-month follow-up (n=17).

SETTING

Participants attended courses that were run in Queensland and Victorian communities and through one national organisation.

PARTICIPANTS

Participants were 49 adults who worked directly with Aboriginal and/or Torres Strait Islander Peoples.

INTERVENTION

The 5-hour 'Talking About Non-Suicidal Self-Injury' course was delivered by accredited AMHFA instructors and teaches people how to support an Aboriginal and/or Torres Strait Islander person who is engaging in NSSI.

PRIMARY AND SECONDARY OUTCOME MEASURES

The outcome measures were stigmatising attitudes, confidence in ability to assist, and intended and actual actions to assist a person engaging in NSSI.

RESULTS

Improvements were observed in stigmatising attitudes, with significant changes from precourse in both the 'weak-not-sick' (postcourse p<0.0623; follow-up p=0.0058) and 'dangerous/unpredictable' (postcourse p<0.0001; follow-up p=0.0036) subscales. Participants' confidence in ability to assist increased significantly both postcourse (p<0.0001) and at follow-up (p<0.0001). Despite a high level of endorsement for the nine recommended assisting actions at precourse, significant improvements (p<0.05) were observed in endorsement for six and four of the assisting actions postcourse and at follow-up, respectively. Course content was rated as being somewhat (3.4%), mostly (13.8%) or very (82.7%) culturally appropriate by participants who identified as Aboriginal and/or Torres Strait Islander.

CONCLUSIONS

The results of this uncontrolled trial were encouraging, suggesting that the Talking About Non-Suicidal Self-Injury course was able to improve participants' attitudes, confidence and intended assisting actions.

The influence of parenting style and coping behavior on nonsuicidal self-injury behavior in different genders based on path analysis

Background

Nonsuicidal self-injury (NSSI) behaviors-an important factor that profoundly affects the physical and mental health of young people-are induced by complex and diverse factors, while showing significant differences at the gender level. We examined mediating behaviors among parenting styles, students' coping styles, and endogenous and exogenous influencing variables of adolescents' NSSI behaviors.

Methods

In this cross-sectional study, Secondary school students in Ningbo, Zhejiang Province, China (n = 2,689; F/M:1532/1157) were surveyed for basic attributes, parenting styles, coping styles, and NSSI behaviors. After the initial screening of the sample data, several external derivatives were screened based on the single factor analysis method. On this basis, the construction of path analysis models under multivariate multiple elicitations was carried out.

Results

The overall prevalence of NSSI was 15.16%, and the incidence of NSSI in boys was lower than that in girls (OR = 0.334, 95% CI [0.235-0.474]). The path analysis model data fit well; the indicators of female and male part are: CFI = 0.913/0.923, GFI = 0.964/0.977, SRMR = 0.055/0.047, RMSEA = 0.097/0.069 with 90% confidence interval (CI) [0.084-0.111]/[0.054-0.084]. For female, when negative coping style and extreme education affect NSSI respectively, the standardized path coefficient values are 0.478 (z = 20.636, P = 0.000 < 0.01) and 0.151 (z = 6.524, P = 0.000 < 0.01) respectively, while for male, the corresponding values become 0.225 (z = 7.057, P < 0.001) and 0.104 (z = 3.262, P < 0.001).

Conclusion

In particular, we investigated the mediating effects of gender-specific NSSI influences and found that NSSI behaviors were strongly associated with environmental variables and individual factors, especially family parenting style and adolescent coping style, which influenced NSSI in a gender-specific manner. The results showed that males were the target of both positive and negative parenting styles, whereas females were more likely to choose negative coping styles directed towards emotions in response to external stimuli, and instead showed a more significant predisposition towards NSSI behaviors. This phenomenon seems to be influenced by multilevel factors such as sociocultural, individual value identity, and physiological structure differences. In the path analysis model with the introduction of mediating effects, the influence of gender differences on NSSI behavior becomes more pronounced under the interaction of multiple factors: women seem to be more significantly influenced by the external derivatives in the internal derivatives than male subjects, and are more likely to trigger NSSI behavior under the interaction of multiple factors. These findings effectively reveal the significant role of different end-influencing factors in NSSI behaviors at the level of gender differences, which can provide effective theoretical support to prevent and treat NSSI behaviors in adolescents.

Getting "clean" from nonsuicidal self-injury: Experiences of addiction on the subreddit r/selfharm

BACKGROUND & AIMS

Previous studies have shown that nonsuicidal self-injury (NSSI) has addictive features, and an addiction model of NSSI has been considered. Addictive features have been associated with severity of NSSI and adverse psychological experiences. Yet, there is debate over the extent to which NSSI and substance use disorders (SUDs) are similar experientially.

METHODS

To evaluate the extent that people who self-injure experience NSSI like an addiction, we coded the posts of users of the subreddit r/selfharm (n = 500) for each of 11 DSM-5 SUD criteria adapted to NSSI.

RESULTS

A majority (76.8%) of users endorsed at least two adapted SUD criteria in their posts, indicative of mild, moderate, or severe addiction. The most frequently endorsed criteria were urges or cravings (67.6%), escalating severity or tolerance (46.7%), and NSSI that is particularly hazardous. User-level addictive features positively predicted number of methods used for NSSI, number of psychiatric disorders, and particularly hazardous NSSI, but not suicidality. We also observed frequent use of language and concepts common in SUD recovery circles like Alcoholics Anonymous.

DISCUSSION & CONCLUSION

Our findings support previous work describing the addiction potential of NSSI and associating addictive features with clinical severity. These results suggest that NSSI and SUD may share experiential similarities, which has implications for the treatment of NSSI. We also contribute to a growing body of work that uses social media as a window into the subjective experiences of stigmatized populations.

Do Gender and Age Moderate the Relationship between Friendship Quality and Non-Suicidal Self-Injury in Community Children and Adolescents?

In the present study, we investigated the relationship between friendship quality (dimensions) and non-suicidal self-injury (NSSI) as well as the moderating role of gender and age in this relationship. The sample consisted of 463 children and adolescents (50.10% female, age range: 9–17 years). Friendship quality and NSSI were measured using the Friendship Qualities Scale (FQS; Bukowski, Hoza, & Boivin, 1994) and the Self Harm Inventory (SHI; Sansone, Wiederman, & Sansone, 1998), respectively. Overall, total friendship quality and NSSI were significantly and negatively related. Additionally, the relationship between total friendship quality and NSSI was moderated by gender and age. Specifically, girls with low friendship quality reported more NSSI; whereas for boys an opposite effect was found. As for age, friendship quality and NSSI were positively related in older participants. In younger participants, a relationship between friendship quality and NSSI seemed rather absent. This study highlights the important association between friendship quality and NSSI, as well as gender- and age-related differences in this association, which should be taken into account in the prevention and treatment of NSSI.

An online, single-session intervention for adolescent self-injurious thoughts and behaviors: Results from a randomized trial

BACKGROUND

Across 50 years of research, existing interventions for self-injurious thoughts and behaviors (SITBs) in adolescents have remained largely ineffective and inaccessible. Single-session interventions, interventions designed to last one session, may be a low-cost and timely resource for adolescents engaging in SITBs who may not otherwise receive treatment.

METHOD

565 adolescents (M_age = 14.95 years) endorsing recent engagement in non-suicidal self-injury (NSSI) were randomized to receive a 30-min, web-based, single-session intervention-"Project SAVE"-or an active, attention-matched control program. Proximal outcomes were measured at baseline and immediately post-intervention. Long-term outcomes were measured at baseline and 3-month follow-up.

RESULTS

Adolescents rated Project SAVE as acceptable; 80% of participants randomized to SAVE completed the intervention. Between-group effects were non-significant for pre-registered outcomes: post-intervention likelihood of future NSSI; 3-month frequencies of NSSI and suicidal ideation at follow-up. Relative to control-group participants, SAVE participants reported short-term improvements in two exploratory outcomes: self-hatred (d = -.35, p<.001) and desire to stop future NSSI (d = .25, p = .003).

CONCLUSIONS

Project SAVE is an acceptable resource for adolescents engaging in SITBs-with short-term effects on clinically-relevant outcomes. Future research may evaluate SAVE as an easy-to-access, short-term coping resource for youth engaging in SITBs. CLINICAL TRIALS.

Function and progression of non-suicidal self-injury and relationship with suicide attempts: A qualitative investigation with an adolescent clinical sample

AIM

To investigate the function and progression of non-suicidal self-injury (NSSI) and its relationship with suicide attempts.

METHOD

Qualitative in-depth interviews were conducted with 15 adolescents psychiatrically hospitalized following a suicide attempt who reported NSSI. Applied thematic analysis was used to identify and examine themes from the interview data.

RESULTS

Thematic analysis revealed that the primary function of NSSI was relief from emotional pain, though the function often changed over time. NSSI was often not directly related to patients' suicide attempts, yet risk of suicidal behavior seemed to increase once NSSI lost its effectiveness, and suicide became the only option.

CONCLUSION

Clinicians need to understand and monitor the functions of NSSI, and its relationship with suicidality, to prevent suicide attempts among adolescents.

Alexithymia is associated with neural reactivity to masked emotional faces in adolescents who self-harm

BACKGROUND

Non-suicidal self-injury (NSSI) is a major, trans-diagnostic mental health problem among adolescents. Alexithymia has been identified as a developmental risk factor for NSSI. Research on how alexithymia relates to the neurobiology of automatic emotion processing is only beginning to emerge. This study evaluates the relationship between alexithymic features and neural responses to automatic processing of emotional content in adolescents with NSSI.

METHODS

25 female adolescents (ages 13-21) with a history of repeated engagement in NSSI completed the Toronto Alexithymia Scale and the Difficulties with Emotion Regulation Scale and underwent functional magnetic resonance imaging (fMRI) during a task in which participants were exposed to masked emotions.

RESULTS

One facet of alexithymia, limited internal emotion awareness or externally-oriented thinking (EOT), was related to differential reactivity to masked emotional faces in clusters in the right supramarginal gyrus and right inferior frontal gyrus. Follow-up assessment of regional reactivity revealed that greater EOT is associated with lower activation to masked happy faces but higher activation to masked fearful faces. Other facets of alexithymia did not show relationships with reactivity to masked emotional faces.

LIMITATIONS

This is a cross-sectional and small sample that only includes females, which may attenuate generalizability of findings.

CONCLUSIONS

We report neural correlates of multiple facets of alexithymia in adolescents with NSSI. Among adolescents who self-harm, those with higher levels of EOT may be less alert to subtle positively-valenced emotion cues. For this subset of adolescents with NSSI, interventions designed to enhance mental representation of emotional responses and attention to positive emotions may be appropriate.

A 'choice', an 'addiction', a way 'out of the lost': exploring self-injury in autistic people without intellectual disability

Background

Non-suicidal self-injury (NSSI) describes a phenomenon where individuals inflict deliberate pain and tissue damage to their bodies. Self-injurious behaviour is especially prevalent across the autism spectrum, but little is understood about the features and functions of self-injury for autistic individuals without intellectual disability, or about the risk factors that might be valuable for clinical usage in this group.

Methods

One hundred and three autistic adults who responded to an online advertisement were classified as current, historic or non-self-harmers in accordance with responses to the Non-Suicidal Self-Injury Assessment Tool (NSSI-AT). Multinomial regression aimed to predict categorisation of participants in accordance with scores on tests of autistic traits, alexithymia, depression, anxiety, mentalising and sensory sensitivity. Linear regression examined relationships between these predictors and the range, frequency, lifetime occurrence and functional purposes of NSSI. Qualitative analysis explored the therapeutic interventions that participants had found helpful, and what they wished people understood about self-injury.

Results

Current, historic and non-self-harming participants did not differ in age, age at diagnosis, male-to-female ratio, level of employment or education (the majority qualified to at least degree level). The most common function of NSSI was the regulation of low-energy affective states (depression, dissociation), followed by the regulation of high-energy states such as anger and anxiety. Alexithymia significantly predicted the categorisation of participants as current, historic or non-self-harmers, and predicted use of NSSI for regulating high-energy states and communicating distress to others. Depression, anxiety and sensory-sensitivity also differentiated participant groups, and sensory differences also predicted the range of bodily areas targeted, lifetime incidence and frequency of NSSI. Sensory differences, difficulty expressing and identifying emotions also emerged as problematic in the qualitative analysis, where participants expressed the need for compassion, patience, non-judgement and the need to recognise diversity between self-harmers, with some participants perceiving NSSI as a practical, non-problematic coping strategy.

Conclusions

Alexithymia, depression, anxiety and sensory differences may place some autistic individuals at especial risk of self-injury. Investigating the involvement of these variables and their utility for identification and treatment is of high importance, and the voices of participants offer guidance to practitioners confronted with NSSI in their autistic clients.

Riding the emotional roller coaster: The role of distress tolerance in non-suicidal self-injury

Non-Suicidal Self-Injury (NSSI) is the deliberate damage to one's bodily tissue without suicidal intent. The Emotional Cascade Model proposes NSSI functions as a distraction from 'cascades' of intense affect and rumination. Low distress tolerance is one factor thought to potentially amplify these cascades but has yet to be empirically tested. Using the Emotional Cascade Model as a framework, we investigated the moderating roles of rumination and distress tolerance in the relationship between affect intensity and NSSI. A sample of 400 university students between the ages of 17 and 62 years (M = 21.02, SD = 5.32) completed well-validated measures of NSSI, affect intensity, rumination, and distress tolerance. As expected, rumination was associated with history of NSSI but only among individuals who reported high levels of distress tolerance. Further, affect intensity was positively associated with NSSI frequency, but only at low levels of rumination and distress tolerance. These results provide promising insight into potential prevention and intervention initiatives that may target rumination and distress tolerance to reduce the likelihood and frequency of self-injury.

Novel online daily diary interventions for nonsuicidal self-injury: a randomized controlled trial

BACKGROUND

Nonsuicidal self-injury (NSSI), which involves self-damaging behavior (e.g., cutting) causes tissue damage and places people at elevated risk for future suicidal behaviors. Yet few specific treatments for NSSI currently exist. Extreme self-criticism is implicated in the development and maintenance of NSSI. We conducted a randomized controlled trial to evaluate Autobiographical Self-Enhancement Training (ASET), a novel, cognitive intervention for NSSI focused on reducing self-criticism and enhancing positive self-worth. We also examined whether Expressive Writing (EW) was a helpful treatment for NSSI.

METHOD

Participants (N = 144) who had engaged in NSSI at least twice in the past month were recruited online and then randomly assigned via Qualtrics to receive the ASET intervention (N = 49), the EW intervention (N = 49), or Daily Journaling [JNL; N = 46]), an active comparison condition. Treatments were designed as month-long daily diaries. Participants in ASET wrote about something that made them feel good about themselves that day, participants in EW described something that had been on their mind that day, and participants in JNL reported on the events of the day in a factually descriptive manner without emotional content.

RESULTS

Intent-to-treat analyses revealed that, regardless of treatment group, participants showed significant reductions in self-criticism, NSSI episodes, depression, and suicide ideation from baseline to the end of active treatment. Relative to the JNL group, the ASET group reported significantly less self-criticism at post-treatment; this was not maintained at follow-up. There was also a trend toward ASET being associated with less suicide ideation at the end of treatment compared to EW. This difference was significant at the 3-month follow-up. Unexpectedly, the JNL group reported significantly less suicide ideation than the EW group at post-treatment; this was maintained at 3-month follow-up. No significant treatment effects were detected for suicide plans, suicidal behaviors, desire to discontinue NSSI, or likelihood of future NSSI.

CONCLUSION

Self-criticism is an important treatment target in NSSI, but changing self-criticism in people with an established history of NSSI presents challenges. Nonetheless, all approaches provided benefits. This study also established the feasibility of inexpensive and easily disseminated treatments for NSSI.

Prefrontal cortex activation during cognitive interference in nonsuicidal self-injury

Nonsuicidal self-injury (NSSI), deliberate behavior resulting in self-inflicted damage to oneself, is common, particularly among female adolescents, and may be a form of maladaptive emotion regulation. Cognitive interference, a specific type of processing associated with inhibiting prepotent responses in favor of less automatic ones, is utilized in treatment strategies to shift patients' thoughts and behaviors away from maladaptive responses and replace them with more adaptive ones. We examined cognitive interference processing using the Multi-Source Interference Task (MSIT) in females with NSSI behavior (n=15) and healthy control females (n=15). Functional magnetic resonance imaging (fMRI) data were collected concurrently. Results revealed similar between-group performance on the MSIT; however, women with NSSI behavior exhibited altered patterns of neural activation during the MSIT. Specifically, the NSSI group demonstrated increased cingulate cortex (CC) and decreased dorsolateral prefrontal cortex (DLPFC) activation compared to the control group. Further, within the NSSI group, DLPFC activation inversely correlated with emotional reactivity and self-reported impulsivity, suggesting that decreased DLPFC activation is associated with poorer emotional control and increased impulsivity. Taken together, these results indicate that women with NSSI behavior utilize different cortical areas during cognitive interference processing, which may have broader implications regarding the treatment efficacy of cognitive-based therapies.

Non-Suicidal Self-Injury Elevates Suicide Risk among United States Military Personnel with Lifetime Attempted Suicide

Military psychiatric inpatients with and without a lifetime history of non-suicidal self-injury (NSSI), combined with a history of at least one suicide attempt, were compared on suicide ideation severity, number of suicide attempts, and Interpersonal-Psychological Theory of Suicide variables. Data were derived from baseline assessments performed in a psychotherapy randomized controlled trial. Lifetime history of NSSI and lifetime number of suicide attempts were assessed using the Columbia Suicide Severity Rating Scale (C-SSRS; Posner et al., 2011 ). Individuals with versus without a combined lifetime history of attempted suicide and NSSI showed significant elevations on thwarted belongingness and acquired capability for suicide. No significant between-group differences were found on perceived burdensomeness, frequency, duration, and controllability of suicide ideation, or number of lifetime suicide attempts. A history of NSSI, above and beyond attempted suicide, appears to increase service members' social alienation and acquired capability for suicide.

Affect toward the self and self-injury stimuli as potential risk factors for nonsuicidal self-injury

Few risk factors for nonsuicidal self-injury (NSSI) have been identified. This study investigated diminished aversion toward self-injury (i.e., NSSI, suicide/death stimuli) and self-criticism as unique NSSI risk factors. After terminating a treatment study, 154 adults with a recent and frequent NSSI history completed self-report and computer-based measures of psychopathology, implicit and explicit self-criticism, and implicit aversion to NSSI and suicide/death. Participants were then contacted 4 weeks later to test factors predicting NSSI frequency over this follow-up period. Diminished aversion toward NSSI stimuli and self-criticism significantly predicted NSSI 4 weeks later. These effects were unique from other theoretically important predictors, such as past week NSSI frequency and total number of NSSI methods used. Findings provide support that erosion of barriers to NSSI (e.g., aversion to self-injurious stimuli, decreased self-worth) may facilitate continued engagement in these dangerous behaviors. Results shed light on potential treatment targets for NSSI.

Re-development of mental health first aid guidelines for supporting Aboriginal and Torres Strait Islanders who are engaging in non-suicidal self-injury

BACKGROUND

Non-suicidal self-injury (NSSI) disproportionally affects Indigenous Australians. Friends, family and frontline workers (for example, teachers, youth workers) are often best positioned to provide initial assistance if someone is engaging in NSSI. Culturally appropriate expert consensus guidelines on how to provide mental health first aid to Australian Aboriginal and Torres Strait Islanders who are engaging in NSSI were developed in 2009. This study describes the re-development of these guidelines to ensure they contain the most current recommended helping actions.

METHODS

The Delphi consensus method was used to elicit consensus on potential helping statements to be included in the guidelines. These statements describe helping actions that Indigenous community members and non-Indigenous frontline workers can take, and information they should have, to help someone who is engaging in NSSI. The statements were sourced from systematic searches of peer-reviewed literature, grey literature, books, websites and online materials, and existing NSSI courses. A panel was formed, comprising 26 Aboriginal and Torres Strait Islanders with expertise in NSSI. The panellists were presented with the helping statements via online questionnaires and were encouraged to suggest re-wording of statements and any additional helping statements that were not included in the original questionnaire. Statements were only accepted for inclusion in the guidelines if they were endorsed by ≥90% of panellists as essential or important.

RESULTS

From a total of 185 statements shown to the expert panel, 115 were endorsed as helping statements to be included in the re-developed guidelines.

CONCLUSIONS

A panel of Aboriginal and Torres Strait Islander people with expertise in NSSI were able to reach consensus on appropriate strategies for providing mental health first aid to an Aboriginal and Torres Strait Islander engaging in NSSI. The re-development of the guidelines has resulted in more comprehensive guidance than the earlier version. The re-developed guidelines will form the basis of an Aboriginal mental health first aid short course on NSSI for Indigenous community members and non-Indigenous frontline workers that will be evaluated in an upcoming trial.

Nonsuicidal Self-Injury

Nonsuicidal self-injury (NSSI) is a serious and prevalent problem within the adolescent population. NSSI is associated with a variety of psychiatric diagnoses and behavioral concerns. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition, has recognized NSSI as its own separate diagnosis. Although there are unique differences between NSSI and suicidal behaviors, a link exists between these behaviors. It is crucial that pediatric nurse practitioners who provide care for adolescents possess a thorough understanding of NSSI. In this continuing education article, NSSI will be discussed in terms of epidemiology, diagnosis and co-morbidity, risk factors, relationship with suicidal behaviors, and implications for practice.

Interventions for self-harm in children and adolescents

BACKGROUND

Self-harm (SH; intentional self-poisoning or self-injury) is common in children and adolescents, often repeated, and strongly associated with suicide. This is an update of a broader Cochrane review on psychosocial and pharmacological treatments for deliberate SH first published in 1998 and previously updated in 1999. We have now divided the review into three separate reviews; this review is focused on psychosocial and pharmacological interventions for SH in children and adolescents.

OBJECTIVES

To identify all randomised controlled trials of psychosocial interventions, pharmacological agents, or natural products for SH in children and adolescents, and to conduct meta-analyses (where possible) to compare the effects of specific treatments with comparison types of treatment (e.g., treatment as usual (TAU), placebo, or alternative pharmacological treatment) for children and adolescents who SH.

SEARCH METHODS

For this update the Cochrane Depression, Anxiety and Neurosis Group (CCDAN) Trials Search Co-ordinator searched the CCDAN Specialised Register (30 January 2015).

SELECTION CRITERIA

We included randomised controlled trials comparing psychosocial or pharmacological treatments with treatment as usual, alternative treatments, or placebo or alternative pharmacological treatment in children and adolescents (up to 18 years of age) with a recent (within six months) episode of SH resulting in presentation to clinical services.

DATA COLLECTION AND ANALYSIS

Two reviewers independently selected trials, extracted data, and appraised study quality, with consensus. For binary outcomes, we calculated odds ratios (OR) and their 95% confidence intervals (CI). For continuous outcomes measured using the same scale we calculated the mean difference (MD) and 95% CI; for those measured using different scales we calculated the standard mean difference (SMD) and 95% CI. Meta-analysis was only possible for two interventions: dialectical behaviour therapy for adolescents and group-based psychotherapy. For these analyses, we pooled data using a random-effects model.

MAIN RESULTS

We included 11 trials, with a total of 1,126 participants. The majority of participants were female (mean = 80.6% in 10 trials reporting gender). All trials were of psychosocial interventions; there were none of pharmacological treatments. With the exception of dialectical behaviour therapy for adolescents (DBT-A) and group-based therapy, assessments of specific interventions were based on single trials. We downgraded the quality of evidence owing to risk of bias or imprecision for many outcomes.Therapeutic assessment appeared to increase adherence with subsequent treatment compared with TAU (i.e., standard assessment; n = 70; k = 1; OR = 5.12, 95% CI 1.70 to 15.39), but this had no apparent impact on repetition of SH at either 12 (n = 69; k = 1; OR 0.75, 95% CI 0.18 to 3.06; GRADE: low quality) or 24 months (n = 69; k = 1; OR = 0.69, 05% CI 0.23 to 2.14; GRADE: low quality evidence). These results are based on a single cluster randomised trial, which may overestimate the effectiveness of the intervention.For patients with multiple episodes of SH or emerging personality problems, mentalisation therapy was associated with fewer adolescents scoring above the cut-off for repetition of SH based on the Risk-Taking and Self-Harm Inventory 12 months post-intervention (n = 71; k = 1; OR = 0.26, 95% CI 0.09 to 0.78; GRADE: moderate quality). DBT-A was not associated with a reduction in the proportion of adolescents repeating SH when compared to either TAU or enhanced usual care (n = 104; k = 2; OR 0.72, 95% CI 0.12 to 4.40; GRADE: low quality). In the latter trial, however, the authors reported a significantly greater reduction over time in frequency of repeated SH in adolescents in the DBT condition, in whom there were also significantly greater reductions in depression, hopelessness, and suicidal ideation.We found no significant treatment effects for group-based therapy on repetition of SH for individuals with multiple episodes of SH at either the six (n = 430; k = 2; OR 1.72, 95% CI 0.56 to 5.24; GRADE: low quality) or 12 month (n = 490; k = 3; OR 0.80, 95% CI 0.22 to 2.97; GRADE: low quality) assessments, although considerable heterogeneity was associated with both (I(2) = 65% and 77% respectively). We also found no significant differences between the following treatments and TAU in terms of reduced repetition of SH: compliance enhancement (three month follow-up assessment: n = 63; k = 1; OR = 0.67, 95% CI 0.15 to 3.08; GRADE: very low quality), CBT-based psychotherapy (six month follow-up assessment: n = 39; k = 1; OR = 1.88, 95% CI 0.30 to 11.73; GRADE: very low quality), home-based family intervention (six month follow-up assessment: n = 149; k = 1; OR = 1.02, 95% CI 0.41 to 2.51; GRADE: low quality), and provision of an emergency card (12 month follow-up assessment: n = 105, k = 1; OR = 0.50, 95% CI 0.12 to 2.04; GRADE: very low quality). No data on adverse effects, other than the planned outcomes relating to suicidal behaviour, were reported.

AUTHORS' CONCLUSIONS

There are relatively few trials of interventions for children and adolescents who have engaged in SH, and only single trials contributed to all but two comparisons in this review. The quality of evidence according to GRADE criteria was mostly very low. There is little support for the effectiveness of group-based psychotherapy for adolescents with multiple episodes of SH based on the results of three trials, the evidence from which was of very low quality according to GRADE criteria. Results for therapeutic assessment, mentalisation, and dialectical behaviour therapy indicated that these approaches warrant further evaluation. Despite the scale of the problem of SH in children and adolescents there is a paucity of evidence of effective interventions. Further large-scale trials, with a range of outcome measures including adverse events, and investigation of therapeutic mechanisms underpinning these interventions, are required. It is increasingly apparent that development of new interventions should be done in collaboration with patients to ensure that these are likely to meet their needs. Use of an agreed set of outcome measures would assist evaluation and both comparison and meta-analysis of trials.

Meta-analysis of risk factors for nonsuicidal self-injury

Nonsuicidal self-injury (NSSI) is a prevalent and dangerous phenomenon associated with many negative outcomes, including future suicidal behaviors. Research on these behaviors has primarily focused on correlates; however, an emerging body of research has focused on NSSI risk factors. To provide a summary of current knowledge about NSSI risk factors, we conducted a meta-analysis of published, prospective studies longitudinally predicting NSSI. This included 20 published reports across 5078 unique participants. Results from a random-effects model demonstrated significant, albeit weak, overall prediction of NSSI (OR=1.59; 95% CI: 1.50 to 1.69). Among specific NSSI risk factors, prior history of NSSI, cluster b, and hopelessness yielded the strongest effects (ORs>3.0); all remaining risk factor categories produced ORs near or below 2.0. NSSI measurement, sample type, sample age, and prediction case measurement type (i.e., binary versus continuous) moderated these effects. Additionally, results highlighted several limitations of the existing literature, including idiosyncratic NSSI measurement and few studies among samples with NSSI histories. These findings indicate that few strong NSSI risk factors have been identified, and suggest a need for examination of novel risk factors, standardized NSSI measurement, and study samples with a history of NSSI.

Nonsuicidal self-injury in Indian adolescents: Nonexistent or unacknowledged?

Nonsuicidal self-injury (NSSI) has been a neglected entity in low- and middle-income countries (LMICs). In this correspondence (letter to the editor), authors are advocating for greater research in this area in LMICs as it will help to compare and contrast prevalence rates of NSSI in these countries with high-income countries (HICs), identify context-specific risk and protective factors to better understand the pathophysiology of NSSI and devise context-specific interventions resulting in improvement in adolescent mental health worldwide.

Treating nonsuicidal self-injury: a systematic review of psychological and pharmacological interventions

OBJECTIVE

Nonsuicidal self-injury (NSSI), the deliberate, self-inflicted damage of bodily tissue without the intent to die, is associated with various negative outcomes. Although basic and epidemiologic research on NSSI has increased during the last 2 decades, literature on effective interventions targeting NSSI is still emerging. Here, we present a comprehensive, systematic review of existing psychological and pharmacological treatments designed specifically for NSSI, or including outcome assessments examining change in NSSI.

METHOD

We conducted a systematic search of PsycINFO, MEDLINE, and ERIC databases to retrieve relevant articles that met inclusion criteria; specifically, uncontrolled and controlled trials that 1) presented quantitative outcome data on NSSI, and 2) clearly differentiated NSSI from suicidal self-injury (SSI). Consistent with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, definition of NSSI, we excluded studies examining populations with developmental or intellectual disabilities, or with psychotic disorders.

RESULTS

Several interventions appear to hold promise for reducing NSSI, including dialectical behaviour therapy, emotion regulation group therapy, manual-assisted cognitive therapy, dynamic deconstructive psychotherapy, atypical antipsychotics (aripiprazole), naltrexone, and selective serotonin reuptake inhibitors (with or without cognitive-behavioural therapy). Nevertheless, there remains a paucity of well-controlled studies investigating treatment efficacy for NSSI.

CONCLUSIONS

Structured psychotherapeutic approaches focusing on collaborative therapeutic relationships, motivation for change, and directly addressing NSSI behaviours seem to be most effective in reducing NSSI. Medications targeting the serotonergic, dopaminergic and opioid systems also have demonstrated some benefits. Future studies employing controlled designs as well as a clear delineation of NSSI and SSI will improve knowledge regarding treatment effects.
