International prevalence of adolescent non-suicidal self-injury and deliberate self-harm

A systematic review of interpersonal processes and their measurement within experience sampling studies of self-injurious thoughts and behaviours

Self-injurious thoughts and behaviours (SITBs) are a leading cause of death, and interpersonal processes (IPs) appear to play a role in SITBs. This systematic review synthesises the literature on IPs and SITBs in daily life and addresses four critical questions: (1) Which IPs have been assessed and how, (2) How are differences in IPs between individuals associated with SITBs?, (3) How are differences in IPs within individuals associated with SITBs? and (4) Do IPs relate differently to self-injurious thoughts than behaviours? Our review followed PRISMA guidelines and eligible literature was screened until 25 April 2024. We identified 58 Experience Sampling studies (32.76% daily-diary studies) of which most focused on IPs from major SITBs theories (e.g., thwarted belongingness) but largely used inconsistent operationalizations. Results from 39 studies investigating within-person associations were mixed. Based on 26 studies, whether differences in IPs between individuals relate to SITBs remains unclear. Three studies have investigated whether IPs relate to the transition from thoughts to behaviours, but temporal models are needed to draw firm conclusions. Studies investigating IPs and SITBs in daily life are largely inconclusive. Psychometrically validated measures are warranted, and future daily-life studies would benefit from drawing on ideation-to-action frameworks.

Exploring the cessation process from adolescence to young adulthood in individuals with lived experience of nonsuicidal self-injury: a qualitative study

INTRODUCTION

Nonsuicidal self-injury (NSSI) is a common and concerning behavior in adolescents. However, most adolescents cease NSSI as they transition into adulthood. Increased knowledge of the cessation process is needed. This study aimed to qualitatively explore the factors contributing to NSSI cessation in individuals with lived experience of NSSI, providing valuable insights for treatment strategies.

METHODS

Twenty-six individuals assigned female sex at birth, between ages 20-22 years, from Sweden were interviewed between 2021 and 2023 in Linköping, Sweden. Of these, 21 individuals perceived themselves as having ceased NSSI and were included in the analysis. Thematic analysis and Hooley and Franklins' Benefits and Barriers Model of NSSI were used to analyze the transcripts.

RESULTS

Three overarching themes were generated: "Something inside me changed", "Something in my close relationships changed", and "Something in my life context changed". The cessation of NSSI was associated with several key factors. Improved well-being and envisioning a different future were pivotal in initiating the cessation process. Additionally, interpersonal relationships and support from others were interpreted as powerful motivators for change. Transitioning to a new social context and leaving behind a destructive environment provided opportunities for personal growth and enhanced well-being, interpreted as initiators in the participants' broader life context.

CONCLUSION

This study underscores the complexity of the NSSI cessation process and highlights the need for a comprehensive understanding of the underlying factors. Access to emotion regulation skills was perceived as a significant barrier to NSSI engagement. Clinical implications and different interventions to support NSSI cessation are discussed.

Factors associated with informal and formal help-seeking among Asian adolescents with nonsuicidal self-injury

Although nonsuicidal self-injury (NSSI) is prevalent among adolescents and is associated with an increased risk of adverse outcomes, many adolescents with NSSI do not seek help. However, there is a lack of research on the factors that may increase the likelihood of help-seeking, especially within Asia. To address this gap, the present study examined whether certain factors were associated with informal and formal help-seeking - specifically gender, severity of NSSI, functions of NSSI and authoritative parenting. 121 adolescents (Mage = 16.2 years, 71.1% female) were recruited from specialist outpatient clinics and inpatient psychiatric wards from a public hospital in Singapore. One caregiver per adolescent was also recruited. Data from self-report questionnaires were analysed using logistics regression analyses. The results suggest that the severity of NSSI increases the likelihood of informal help-seeking, while adolescents who have parents with more authoritative parenting style are less likely to seek informal help. Gender and functions of NSSI were not found to be associated with help-seeking. The findings from this study can guide professionals in their efforts to encourage help-seeking within Asian populations, as well as inform prevention and treatment programs for Asian adolescents with NSSI.

Non-suicidal self-injury among youth students during COVID-19 pandemic: the role of psychological factors in Jingzhou, China

Objective

This study aimed to explore the impact of the COVID-19 pandemic on non-suicidal self-injury (NSSI) among youth students, and the mediating role of psychological factors in the relationship between the COVID-19 pandemic and NSSI.

Method

An online survey was conducted at junior and senior high schools, as well as universities located in Jingzhou, Hubei Province, China between June 2021 and January 2022. The COVID-19 Impact Index was constructed using multiple correspondence analysis (MCA) method. The bootstrapping method was used for mediation analysis.

Results

A total of 16025 youth participated in the study and 12507 youth (78.1%) finished the questionnaires. The COVID-19 Impact Index had a significantly positive effect on NSSI (r=0.16, p<0.001). The mediation analysis results showed that the COVID-19 Impact Index had a significant indirect effect on youth' NSSI (β=0.0918, 95% CI [0.0788, 0.1048]), and this indirect effect was mainly achieved through affecting youth' anxiety, depression and post-traumatic stress disorder (PTSD). The mediation effect of anxiety on NSSI was 0.0584, the direct effect was 0.0334, and the mediation proportion was 63.6%. The mediation effect of depression on NSSI was 0.0668, the direct effect was 0.0250, and the mediation proportion was 72.8%. The mediation effect of PTSD on NSSI was 0.0640, the direct effect was 0.0278, and the mediation proportion was 69.7%. All the mediation effects, direct effects and total effects were statistically significant (p<0.001).

Conclusion

The higher the impact of the COVID-19 Impact Index, the higher the prevalence of NSSI among youth students. Anxiety, depression and PTSD had mediated the relationship between the COVID-19 Impact Index and NSSI. It is suggested that specific health policies, mental health services and interventions should be developed to reduce the NSSI and improve mental health status among youth students during the COVID-19 pandemic.

Deliberate self-harm in adolescents screening positive for attention-deficit / hyperactivity disorder: a population-based study

BACKGROUND

Adolescents with attention-deficit / hyperactivity disorder (ADHD) have an increased risk of self-harm. The risk of self-harm among adolescents who display an elevated level of ADHD symptoms, but without a formal diagnosis, is not well-studied and understood.

OBJECTIVE

To investigate the relationship between self-reported symptoms of ADHD and self-harm in a population-based sample of adolescents.

METHODS

Adolescents in the population-based youth@hordaland study were invited to complete the Adult ADHD Self-Report Scale (ASRS) and the Short Mood and Feelings Questionnaire (SMFQ). They were asked whether they ever deliberately have taken an overdose or tried to harm themselves on purpose, once or multiple times, defined according to the code used in the Child and Adolescent Self-harm in Europe (CASE) Study. Adolescents reporting severe problems on ≥ four of six selected items on the ASRS-v 1.1 screener were defined as ADHD-screen positive (ADHD-SC+), and the remaining sample as ADHD-screen negative (ADHD-SC-). SMFQ score ≥ 12 was used to define a high level of depressive symptoms.

RESULTS

A total of 9692 adolescents (mean age 17.4 years, 53.1% females) participated in the study, of which 2390 (24.7%) screened positive on the ASRS. ADHD-SC+ adolescents engaged in self-harm more often than the ADHD-SC- group (14.6% vs. 5.4%, OR = 3.02, 95%CI [2.57-3.24]). This remained significant after adjustment for demographic variables, SMFQ score ≥ 12, symptoms of conduct disorder and familial history of self-harm and suicide attempts (OR = 1.58, 95%CI [1.31-1.89]). They were also more likely to report an overdose as their method of self-harm (OR = 1.52, 95%CI [1.05-2.23]). Within the ADHD-SC+ group female sex, high levels of inattention and hyperactivity/impulsivity symptoms, SMFQ score ≥ 12, symptoms indicating conduct disorder and familial history of self-harm and suicide attempts increased the likelihood of engaging in deliberate self-harm.

CONCLUSION

Adolescents who screened positive for ADHD had increased risk of engaging in self-harm. Clinicians should consider the increased risk of such engagement in adolescents who present with high level of ADHD symptoms, even in the absence of a clinical ADHD diagnosis.

Training approaches for the dissemination of clinical guidelines for NSSI: a quasi-experimental trial

BACKGROUND

Non-suicidal self-injury (NSSI) is of high clinical relevance due to its high prevalence and negative long-term implications. In 2016, the German consensus-based clinical guidelines for diagnostic, assessment and treatment of NSSI in childhood and adolescence were published. However, research indicates that clinical guidelines are often poorly implemented in clinical practice. One crucial part of this process is the training of healthcare professionals to transfer knowledge and capacities to bring guideline recommendations into clinical practice.

METHODS

The effect of three different dissemination strategies (printed educational material, e-learning, and blended-learning) on the NSSI guidelines´ recommendations was examined among 671 physicians and psychotherapists via an online-survey. The quasi-experimental study included three measurement points (before the training, after the training, 3-month follow-up) and mixed effects models were used to test for changes in knowledge, competences and attitudes toward NSSI and treatment. Moreover, the transfer of gained competences to practical work and user satisfaction were reviewed.

RESULTS

With all three training formats, the intended changes of the outcome variables could be observed. Hereby, the printed educational material condition showed the lowest improvement in the scores for the 'negative attitudes toward NSSI and those who self-injure'. The training effect remained stable throughout the follow-up measurement. The highest application rate of acquired intervention techniques in clinical practice was reported for the blended-learning condition. For all three training strategies, user satisfaction was high and evaluation of training quality was positive, with printed educational material receiving the lowest and blended-learning the highest evaluations.

CONCLUSIONS

In summary, all three training formats were perceived to be of high quality and seem to be suited to cover the needs of a heterogeneous group of physicians and psychotherapists. The choice of training method could be driven by considering which training goals are desired to be achieved and by the benefit-cost ratio allowing for tailored training approaches.

Assessment of children suicide attempts frequency in the peripandemic period

Objectives

Our study aimed to evaluate patients after suicide attempts treated at the Department of Trauma Surgery for Children in the peripandemic period, assessment of potential risk factors, and the school's participation as the unit responsible for the prevention of suicidal behavior.

Materials and methods

Retrospective review of the medical database at equal time intervals of 24 months to identify patients treated before and after the COVID-19 was done. Thorough analysis including injury mechanism, medical procedures, history of previous mental disorders or suicidal behavior was performed. Furthermore, results were compared with the Polish police suicide statistics.

Results

Based on our retrospective review we found 4 patients treated in our department before the pandemic and 10 patients treated after COVID-19 outbreak. The group before SARS-Cov-2 era consisted of three girls and one boy with a mean age of 14.97 (12.7-17.6). The group treated in the pandemic crisis consisted of 8 boys and 2 girls, the mean age was 15.49 (10.8-17.2). In the pre-COVID-19 group, 2 out of 4 patients had received psychiatric treatment before, but none had attempted suicide before. In the COVID-19 group, 6 out of 10 patients had previously received psychiatric treatment, moreover 3 of them attempted suicide before. Based on our analysis, the number of individuals who displayed suicidal attempts has raised. Between 2018 and 2021 the largest number of suicides concerned the 13-18 y.o. group, both for the Silesian Voivodeship (H = 9.374; p = 0.0092) and for the whole country (H = 10.203; p = 0.0061).

Conclusion

(1) Results of our study indicate that the pandemic may have caused a wide range of negative mental health consequences for young individuals; (2) Suicide attempts in children are often related with high energy trauma; (3) Teachers and school psychologists, as well as medical health providers, should be aware of rising suicide rates among adolescents.

Non-Suicidal Self-Injury in Eating and Feeding Disorder Patients: Characteristics and Clinical Implications in a Group of Referred Female Adolescents

BACKGROUND

Non-suicidal self-injury (NSSI) and Feeding or Eating Disorders (FEDs) often coexist during adolescence with reciprocal influences on their clinical picture. The present study aimed to identify differences and similarities in the clinical presentation of young patients with both conditions compared to those with the two non-comorbid disorders.

METHODS

We consecutively recruited forty-five female patients aged between 11 and 18 at our third-level hospital and subdivided them into three groups (NSSI: n = 15; FED: n = 15; NSSI + FED: n = 15). Patients underwent a full clinical assessment.

RESULTS

Based on our results, the NSSI + FED group was characterized by higher rates of binging/purging behaviors, greater prevalence of Cyclothymic Disorder, and a more severe clinical presentation compared to the non-comorbid groups. Moreover, higher levels of suicidal ideation were found in the NSSI + FED group. Pharmacological treatment patterns also differed, with SSRI being prescribed more frequently to NSSI + FED patients while mood stabilizers were prescribed more frequently to NSSI ones. A Principal Component Analysis identified four main dimensions: "Body Image" impairment was more pronounced in NSSI + FED patients, indicating negative attitudes towards their own body; "Metacognition" deficits were higher in NSSI than FED.

CONCLUSIONS

The present study underscores distinctive clinical features in patients with comorbid NSSI and FED, emphasizing the urgent need for tailored intervention strategies focusing on specific symptom domains.

Neural mechanism of non-adaptive cognitive emotion regulation in patients with non-suicidal self-injury

BACKGROUND

The incidence of non-suicidal self-injury (NSSI) has been on the rise in recent years. Studies have shown that people with NSSI have difficulties in emotion regulation and cognitive control. In addition, some studies have investigated the cognitive emotion regulation of people with NSSI which found that they have difficulties in cognitive emotion regulation, but there was a lack of research on cognitive emotion regulation strategies and related neural mechanisms.

METHODS

This study included 117 people with NSSI (age = 19.47 ± 5.13, male = 17) and 84 non-NSSI participants (age = 19.86 ± 4.14, male = 16). People with NSSI met the DSM-5 diagnostic criteria, and non-NSSI participants had no mental or physical disorders. The study collected all participants' data of Cognitive Emotion Regulation Questionnaire (CERQ) and functional magnetic resonance imaging (fMRI) to explore the differences in psychological performance and brain between two groups. Afterwards, Machine learning was used to select the found differential brain regions to obtain the highest correlation regions with NSSI. Then, Allen's Human Brain Atlas database was used to compare with the information on the abnormal brain regions of people with NSSI to find the genetic information related to NSSI. In addition, gene enrichment analysis was carried out to find the related pathways and specific cells that may have differences.

RESULTS

The differences between NSSI participants and non-NSSI participants were as follows: positive refocusing (t = -4.74, p < 0.01); refocusing on plans (t = -4.11, p < 0.01); positive reappraisal (t = -9.22, p < 0.01); self-blame (t = 6.30, p < 0.01); rumination (t = 3.64, p < 0.01); catastrophizing (t = 9.10, p < 0.01), and blaming others (t = 2.52, p < 0.01), the precentral gyrus (t = 6.04, pFDR < 0.05) and the rolandic operculum (t = -4.57, pFDR < 0.05). Rolandic operculum activity was negatively correlated with blaming others (r = -0.20, p < 0.05). Epigenetic results showed that excitatory neurons (p < 0.01) and inhibitory neurons (p < 0.01) were significant differences in two pathways, "trans-synaptic signaling" (p < -log108) and "modulation of chemical synaptic transmission" (p < -log108) in both cells.

CONCLUSIONS

People with NSSI are more inclined to adopt non-adaptive cognitive emotion regulation strategies. Rolandic operculum is also abnormally active. Abnormal changes in the rolandic operculum of them are associated with non-adaptive cognitive emotion regulation strategies. Changes in the excitatory and inhibitory neurons provide hints to explore the abnormalities of the neurological mechanisms at the cellular level of them. Trial registration number NCT04094623.

A Qualitative Analysis of Perspectives on Self-directed Violence in a Prospective Longitudinal Study of Young Women With and Without Childhood ADHD

OBJECTIVE

Non-suicidal self-directed violence (NSSDV) is a significant and growing youth public health crisis. Girls with ADHD are at increased risk of engaging in NSSDV, yet qualitative studies with this population-to better understand manifestations, motivations, and developmental course-are lacking.

METHOD

We conducted semi-structured, qualitative interviews with a sub-sample of 57 young women (32 with childhood ADHD, 25 neurotypical comparisons; mean age of 27 years, part of a larger prospective longitudinal study) regarding histories and manifestations of NSSDV.

RESULTS

Inductive and deductive analysis revealed several key themes, including self-perceived reasons for engaging in NSSDV (affect regulation, attention seeking, self-punishment, asserting control), impulsivity, secretiveness, and in some cases motivations for desistance.

CONCLUSION

Findings underscore the importance of early education and screening, especially among high-risk clinical populations. Increased resources and supports for professionals, parents, and peers are indicated, along with countering the persistent stigma associated with ADHD and NSSDV.

Sex Differences in the Global Prevalence of Nonsuicidal Self-Injury in Adolescents: A Meta-Analysis

Importance

Nonsuicidal self-injury (NSSI) is a strong predictor of suicide attempts. The prevalence of NSSI has been increasing among female adolescents in North America and Europe, but less is known about trends in other geographical regions.

Objective

To examine sex differences in the prevalence of NSSI among adolescents within and between geographical regions.

Data Sources

MEDLINE and PsycINFO were searched using the keywords adolescents, self-injury, sex factors, and synonyms for articles published in English between January 1, 2000, and May 10, 2022.

Study Selection

Studies were included if they presented original data (any study design), included adolescents aged 10 to 19 years, reported results stratified by sex, and explicitly defined self-injury as behaviors occurring without suicidal intent.

Data Extraction and Synthesis

This meta-analysis was registered with PROSPERO and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Articles were assessed for quality by 2 independent coders (F.M. and J.A.). A random-effects model was used to calculate prevalence. Data were analyzed from July 2022 to April 2023.

Main Outcomes and Measures

The prevalence of NSSI in male and female adolescents within and between regions was the main outcome. Odds ratios (OR) with 95% CIs were calculated for community samples.

Results

Eight hundred and two studies were screened, and 38 were included (266 491 participants). Across 17 countries, the pooled prevalence of NSSI was 17.7% (female:male OR, 1.60; 95% CI, 1.29-1.98). NSSI was twice as prevalent among female adolescents compared with male adolescents in North America (OR, 2.49; 95% CI, 2.16-2.86) and Europe (OR, 2.08; 95% CI, 1.69-2.58), but not in Asia (OR, 1.00; 95% CI, 0.71-1.41).

Conclusions and Relevance

In this meta-analysis of sex differences in global prevalence of NSSI, the female predominance of NSSI observed among adolescents in North America and Europe aligned with rising rates of suicide in these populations. The comparable prevalence of NSSI among male and female adolescents in Asia also aligned with the lower male-to-female suicide ratio compared with other countries. More research is needed to characterize regional (and potentially cultural) sex differences among adolescents with NSSI to prevent and treat the behavior and to understand the possible interplay with corresponding regional trends in suicide.

Risk and Protective Factors of Self-harm and Suicidality in Adolescents: An Umbrella Review with Meta-Analysis

Suicide remains the second most common cause of death in young people aged 10-24 years and is a growing concern globally. The literature reports a vast number of factors that can predispose an adolescent to suicidality at an individual, relational, community, or societal level. There is limited high-level research identifying and understanding these risk and protective factors of adolescent suicidality. The present study used an umbrella review and meta-analysis to synthesize evidence from the review literature in the past 20 years on risk and protective factors of self-harm and suicidality (behavior and ideation) in adolescents. The umbrella review included 33 quantitative reviews with 1149 individual studies on suicidality and self-harm. Based on the data synthesis, it compared the public health impact of exposure on the population of the identified exposure. Bullying victimization was the most attributed environmental exposure for suicidality. The other identified significant school and individual factors were sleeping disturbance, school absenteeism, and exposure to antidepressants. Several significant vulnerable young populations were identified with significantly higher prevalence of suicidality, including lesbian, gay, bisexual, transgender, queer (or questioning) youth and those with mental health disorders, problem behaviors, previous suicidality, self-harm, and gender (female). A person-centered approach emphasizing connectedness and bully-free school environments should be a priority focus for schools, health professionals, and public health policymakers.

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

INTRODUCTION

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

METHODS

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

RESULTS

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

CONCLUSION

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

A Pilot Study Assessing Sexual Behavior as Self-Injury in College Students

OBJECTIVE

The use of sexual activity to self-injure has been proposed in research literature but remains underexplored. The purpose of this pilot study was to determine the feasibility of identifying sexual activity as self-injury in a U.S. college-based sample and to provide a preliminary examination of sexual activity as self-injury to inform future study on this topic.

METHOD

A cross-sectional descriptive pilot study was conducted to assess for recognition of and attitudes toward sexual behavior as self-injury and to identify participant-reported experiences of sexual activity to self-injure.

RESULTS

A total of 50 participants completed the online survey. Thirteen (26%) participants reported they had heard of the concept of "sex as self-injury." Six (12%) participants reported ever having used sexual activity to cause physical or psychological harm to themselves. Participants reported intentions for engaging in sexual activity to self-injure, including causing physical pain, reliving past self-harm or trauma, showing vulnerability, proving self-worth, pleasing or wanting to feel needed by their partner, and suicidal ideation.

CONCLUSION

Sexual activities have been used by some college students as a means of self-harm. Further research is needed to understand this phenomenon and clinicians should consider screening for this in patients who participate in dangerous sexual behaviors or self-injurious behaviors.

Comparing Ruminative and Distracting Responses and Emotion Regulation Difficulties in Early Community Adolescents With and Without Self-Harm

Objectives

This study aimed to compare the demographic characteristics, responses to negative emotions, and difficulties in emotion regulation between self-harming adolescents and control individuals aged 12-14 years from the community.

Methods

Data were collected from adolescents in Chungcheong Province, South Korea, between September 2021 and November 2022. Demographic characteristics and responses to the Depressed Mood Questionnaire and Difficulties in Emotion Regulation Scale-16 (DERS-16) were compared between the self-harm and control groups.

Results

The self-harm group exhibited a higher prevalence of child abuse (odds ratio [OR]=4.787, 95% confidence interval [CI]=1.591-14.409, p=0.005) and school bullying victimization (OR=4.495, 95% CI=2.353-8.588, p<0.001) than those in the control group. The selfharm group displayed higher levels of rumination (t=7.88, p<0.001) and reduced distraction responses (reverse score t=2.25, p=0.025) than those of the control group. Additionally, the self-harm group scored higher on all subscales and the total DERS-16 score (t=7.61, p<0.001).

Conclusion

Interventions for self-harming adolescents should address child abuse and bullying victimization. Prevention programs for self-harming adolescents should focus on reducing rumination responses, increasing distractive responses, and addressing difficulties in emotion regulation using dialectical behavior therapy-skill training.

Association between positive youth development and non-suicidal self-injury: A longitudinal survey of children and adolescents in southwest China, 2019-21

BACKGROUND

Non-suicidal self-injury (NSSI) could lead to serious problems (exp. suicidal attempts) among children and adolescents. Positive youth development (PYD) focuses on comprehensive development instead of a single problem. This study aims to explore the longitudinal relationship between NSSI and PYD among Chinese children and adolescents.

METHODS

The longitudinal study used the three-wave dataset from the Chengdu Positive Child Development (CPCD) in southwest China between 2019 and 2021, including 10,370 participants. The parallel process Latent Growth Curve Model (LGCM) was utilized to analyze the relationship between PYD and NSSI across time.

RESULTS

The study results demonstrated that the initial level of NSSI is negatively associated with the initial value (β = -0.730, p < 0.01) and the growth rate (β = -0.012, p < 0.01) of PYD, and the development rate of the two variables are negatively related to each other(β = -0.120, p < 0.01).

LIMITATIONS

The specific relationships between PYD attributes and NSSI should be explored in the future. And the cultural variation among countries deserves more research. Moreover, the dynamic cohort research leads to a relatively high loss of participants.

CONCLUSIONS

PYD and NSSI are closely associated among children and adolescents. Instead of playing a protective role, PYD tends to be predicted by NSSI behaviors over time.

Non-suicidal self-injury at a Canadian paediatric emergency department

OBJECTIVE

Our primary objective was to determine agreement between non-suicidal self-injury recorded at triage and during subsequent mental health assessment. The secondary objective was to describe patients who reported non-suicidal self-injury.

METHODS

This is a health records review of patients aged 12-18 years who had an Emergency Mental Health Triage form on their health record from an ED visit June 1, 2017-May 31, 2018. We excluded patients with diagnoses of autism spectrum disorder or schizophrenia. We abstracted data from the Mental Health Triage form, Emergency Mental Health and Addictions Service Assessment forms and Assessment of Suicide and Risk Inventory. We calculated Cohen's Kappa coefficient, sensitivity, and negative predictive value to describe the extent to which the forms agreed and the performance of triage for identifying non-suicidal self-injury. We compared the cohort who reported non-suicidal self-injury with those who did not, using t-tests, Wilcoxon rank-sum tests, and chi-square tests.

RESULTS

We screened 955 ED visits and included 914 ED visits where 558 (58.4%) reported a history of non-suicidal self-injury. There were significantly more females in the group reporting non-suicidal self-injury (82.1%, n = 458) compared to the group not reporting non-suicidal self-injury (45.8%, n = 163). Patients reporting non-suicidal self-injury did so in triage and detailed Mental Health Assessment 64.7% of the time (Cohen's Kappa Coefficient 0.6); triage had sensitivity of 71.5% (95% CI 67.3-75.4) and negative predictive value of 71.2% (95% CI 68.2-74.0). Cutting was the most common method of non-suicidal self-injury (80.3%).

CONCLUSION

Screening at triage was moderately effective in identifying non-suicidal self-injury compared to a detailed assessment by a specialised mental health team. More than half of children and adolescents with a mental health-related concern in our ED reported a history of non-suicidal self-injury, most of which were female. This symptom is important for delineating patients' coping strategies.

Cyberbullying and Non-Suicidal Self-Injury (NSSI) in Adolescence: Exploring Moderators and Mediators through a Systematic Review

(1) Objective: This systematic review explores the intricate relationship between cyberbullying and non-suicidal self-injury (NSSI) in adolescents, acknowledging the dynamic nature of these phenomena in the evolving landscape of technology and social norms. (2) Methods: PubMed/MEDLINE, Web of Science, and EMBASE were searched, and 14 studies were selected based on the eligibility criteria, focusing on participants aged 10 to 19, cyberbullying roles, and NSSI as the predictor and outcome variables, respectively. (3) Results: Internalizing symptoms, specifically depression and anxiety, emerged as the most prominent mediators. However, factors such as externalizing symptoms, stress, and negative emotional responses (emotion reactivity, negative emotions) were also identified to play a significant role in the relationship between cyberbullying and NSSI. On the other hand, protective factors against the negative impact of cyberbullying on NSSI risk, such as strong peer connections and school engagement, were identified. (4) Discussions: This review underscores the multidimensional nature of the cyberbullying-NSSI association, emphasizing the roles of potential risk factors such as internalizing and externalizing symptoms, stress, and negative emotional response. Internalizing symptoms played a central role as pathways between cyberbullying victimization and NSSI. Additionally, social factors, including peer connections and school engagement, were found to act as protective elements. (4) Conclusion: Continuous investigation is crucial in order to adapt interventions to the evolving technological and social landscape. The study advocates for targeted interventions that prioritize positive social connections to mitigate the impact of cyberbullying on adolescent well-being.

From early relational experiences to non-suicidal self-injury in anorexia and bulimia nervosa: a structural equation model unraveling the role of impairments in interoception

PURPOSE

Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) frequently exhibit Non-Suicidal Self-Injury (NSSI), yet their co-occurrence is still unclear. To address this issue, the aim of this study was to elucidate the role of impairments in interoception in explaining the NSSI phenomenon in AN and BN, providing an explanatory model that considers distal (insecure attachment/IA and traumatic childhood experiences/TCEs) and proximal (dissociation and emotional dysregulation) risk factors for NSSI.

METHOD

130 patients with AN and BN were enrolled and administered self-report questionnaires to assess the intensity of NSSI behaviors, interoceptive deficits, IA, TCEs, emotional dysregulation and dissociative symptoms.

RESULTS

Results from structural equation modeling revealed that impairments in interoception acted as crucial mediators between early negative relational experiences and factors that contribute to NSSI in AN and BN, particularly emotional dysregulation and dissociation. Precisely, both aspects of IA (anxiety and avoidance) and various forms of TCEs significantly exacerbated interoceptive deficits, which in turn are associated to the emergence of NSSI behaviors through the increase in levels of dissociation and emotional dysregulation.

CONCLUSIONS

The proposed model provided a novel explanation of the occurrence of NSSIs in patients with AN and BN by accounting for the significance of interoception.

The relationship between mobile phone addiction and non-suicidal self-injury: Findings from six universities in Shaanxi province, China

BACKGROUND

Although the development and application of mobile phones have changed various aspects of people's lives, excessive use of mobile phones has also raised physical and mental health concerns. However, the relationship between mobile phone addiction (MPA) and non-suicidal self-injury (NSSI) is unclear.

METHODS

A cross-sectional study was conducted (2022) among students from six universities to assess the relationship between MPA and NSSI. A Mobile Phone Addiction Tendency Scale (MPATS) was used to assess MPA, while NSSI was assessed via The Ottawa Self-Injury Inventory. Binary logistic regression models were used to assess the relationship between MPA and NSSI.

RESULTS

A total of 18,723 college students (6531 males [34.9 %] and 12,192 females [65.1 %]) were included in the final analyses. The prevalence of NSSI during the past 12 months was 6.5 %. Furthermore, 5553 participants (29.7 %) met the MPA criteria (MPATS score ≥ 48), and the average MPATS score was 39.5 ± 13.0. MPA was associated with increased odds of NSSI after adjusting for socio-demographic characteristics, health-related characteristics, and relevant psychosocial variables (OR, 1.29; 95 % CI, 1.13-1.46). Moreover, gender did not affect the association of MPA and MPATS score with NSSI (P for interaction>0.05). The restricted cubic splines regression showed that a monotonically increasing risk of NSSI was associated with increasing MPATS score (P for non-linearity = 0.474).

CONCLUSIONS

MPA is associated with increased odds of NSSI among college students, indicating that early examination, prevention, and intervention for MPA may prevent and control NSSI.

Longitudinal Associations between Different Types of Sexting, Adolescent Mental Health, and Sexual Risk Behaviors: Moderating Effects of Gender, Ethnicity, Disability Status, and Sexual Minority Status

The present study investigated the moderating effect of adolescent demographic variables in the longitudinal associations among different types of sexting, mental health (i.e., depression, self-harm, subjective health complaints), and sexual risk behaviors. There were 1113 adolescents (ages 14-17 years; Mage = 16.36; SDage = .81; 50% female) from six high schools located in the United States included in this study. Adolescents completed questionnaires on their sexting behaviors, mental health, and sexual risk behaviors during the ninth grade; in tenth grade, they completed questionnaires on mental health and sexual risk behaviors. Non-consensual sexting and pressured sexting were both related positively to each of the mental health variables and sexual risk behaviors. The relationship between non-consensual sexting and depressive symptoms was stronger for girls, ethnic minorities, those adolescents with disabilities, and sexual minorities. Similar patterns were found for pressured sexting, non-suicidal self-harm, and subjective health complaints. The relationships between pressured sexting and sexual risk behaviors were stronger for girls, ethnic minorities, those adolescents with disabilities, and those who identified as sexual minorities. Research focused on the relationships among different types of sexting, mental health, and sexual risk behaviors is important as such research facilitates the development of evidence-based recommendations for sexting harm prevention and sexual education programs.

Identifying clinical risk factors correlated with addictive features of non-suicidal self-injury among a consecutive psychiatric outpatient sample of adolescents and young adults

Non-suicidal self-injury (NSSI) is an issue primarily of concern in adolescents and young adults. Recent literature suggests that persistent, repetitive, and uncontrollable NSSI can be conceptualized as a behavioral addiction. The study aimed to examine the prevalence of NSSI with addictive features and the association of this prevalence with demographic and clinical variables using a cross-sectional and case-control design. A total of 548 outpatients (12 to 22 years old) meeting the criteria for NSSI disorder of DSM-5 were enrolled and completed clinical interviews by 4 psychiatrists. NSSI with addictive features were determined by using a single-factor structure of addictive features items in the Ottawa self-injury inventory (OSI). Current suicidality, psychiatric diagnosis, the OSI, the revised Chinese Internet Addiction Scale, the Childhood Trauma Questionnaire, and the 20-item Toronto Alexithymia Scale were collected. Binary logistic regression analyses were used to explore associations between risk factors and NSSI with addictive features. This study was conducted from April 2021 to May 2022. The mean age of participants was 15.93 (SD = 2.56) years with 418 females (76.3%), and the prevalence of addictive NSSI was 57.5% (n = 315). Subjects with addictive NSSI had a higher lifetime prevalence of nicotine and alcohol use, a higher prevalence of current internet addiction, suicidality, and alexithymia, and were more likely to have physical abuse/neglect, emotional abuse, and sexual abuse than NSSI subjects without addictive features. Among participants with NSSI, the strongest predictors of addictive features of NSSI were female (OR = 2.405, 95% CI 1.512-3.824, p < 0.0001), alcohol use (OR = 2.179, 95% CI 1.378-3.446, p = 0.001), current suicidality (OR = 3.790, 95% CI 2.351-6.109, p < 0.0001), and psysical abuse in childhood (OR = 2.470, 95% CI 1.653-3.690, p < 0.0001). Nearly 3 out of 5 patients (12-22 years old) with NSSI met the criteria of NSSI with addictive features in this psychiatric outpatients sample. Our study demonstrated the importance of the necessity to regularly assess suicide risk, and alcohol use, as well as focus more on females and subjects who had physical abuse in childhood to prevent addictive NSSI.

Association between the Big Five personality traits and suicide-related behaviors in Japanese institutionalized youths

Aim

Inmates in correctional institutions experience higher rates of suicide attempt (SA), suicidal ideation (SI), and nonsuicidal self-injury (NSSI) than the general population. This study aimed to examine the association between the Big Five personality traits and suicide-related behavior, and to estimate the prevalence rate of such behaviors among Japanese institutionalized youth.

Methods

The participants were 436 youths who had been admitted to four juvenile classification homes (JCHs) between September 2021 and March 2023; they were asked to respond to a self-report questionnaire after obtaining informed consent.

Results

A total of 8.1% and 19.3%, 29.4% and 44.7%, and 46.3% and 75.3% of males and females had experienced SA, SI, and NSSI in their lifetime, respectively. Females reported significantly higher instances of suicide-related behaviors than males considering all suicide-related behaviors. Logistic regression analyses revealed that neuroticism significantly increased the odds ratios for SA, SI, and NSSI on controlling for sex, age, and number of admissions to JCHs. For NSSI, the odds ratio for agreeableness was significantly lower than 1, indicating a lower probability of NSSI.

Conclusion

The findings of our study demonstrate that neuroticism, one of the Big Five traits, was consistently and significantly associated with all suicide-related behaviors, including SA, SI, and NSSI, among youth offenders, while agreeableness was found as a protective factor only against NSSI. The results of this study might help correctional officers identify justice-involved youth at higher risk for suicide and allow the development of early interventions to prevent suicide.

Sexual Activity as Self-Injury: A Scoping Review

Suicide and other self-injurious behaviors (SIB) are significant causes of morbidity and mortality as well as healthcare costs. Sexual risk behaviors are associated with many SIB, and sexual activities may act as SIB as well. In this scoping review, we consider ways in which sexual activity has been conceptualized as SIB - types of sexual activities as a form of self-injury - and cases in which sexual activities as SIB have been classified as direct or indirect self-injury. We include English-language publications that discuss any aspect of sexual activity as SIB. Database, citation list, and gray literature searches yielded 33 publications. Sexual activities as a form of self-injury included exposure to HIV/AIDS and other sexually transmitted infections, sadomasochistic behaviors undertaken for punishment rather than pleasure, selling sex, injury to the genitals, and sexual encounters with undesired partners or consisting of undesired acts. Twenty-three publications did not categorize sexual activities to self-injure as either direct or indirect self-injury, three publications categorized them as indirect self-injury, and seven publications as direct self-injury. Sexual activity is used to self-injure in a variety of ways and its conceptualization as indirect or direct self-injury remains unclear.

Prevalence of suicide attempt and associations with deliberate self-harm, mental health problems, drug misuse and traumatic experiences - a cross sectional survey of the Norwegian population

BACKGROUND

Monitoring self-reported suicide attempts (SA) with nationally representative surveys is important to initiate suicide prevention strategies. The aim of the study was to assess the prevalence of SA and compare deliberate self-harm, (DSH), mental health, drug misuse and traumas between SA and non-suicide attempters (NSA).

METHODS

In this cross-sectional survey of a representative sample (N=1757) of the Norwegian population, we compared people with self-reported SA (n=54) to NSA (n=1703) regarding sociodemographic data, mental health problems, drug misuse and exposure to trauma.

RESULTS

The prevalence of SA was 3.1 %. There was a higher proportion of welfare recipients and more deliberate self-harm, mental health problems, drug misuse and traumas in the SA group compared to NSA.

CONCLUSION

This national study confirms the association between suicide attempt and deliberate self-harm, mental health problems, drug misuse and traumas.

Zero Self-Harm app: a mobile phone application to reduce non-suicidal self-injury-study protocol for a randomized controlled trial

BACKGROUND

Non-suicidal self-injury (NSSI) is a growing healthcare problem. Individuals with NSSI have an increased risk of suicidality. Due to stigma, they may self-injure in secret, which means they might not seek help until events have escalated to include suicidal ideation or a mental disorder. Interventions delivered via mobile phone applications (apps) have been linked to reductions in self-injury. This protocol outlines a trial, which examines whether the Zero Self-Harm intervention, consisting of an app for people with NSSI, can reduce the number of NSSI episodes, suicide ideation, and depressive symptoms.

METHODS

The trial will be conducted as a 6-month 2-arm, parallel-group, multicentre, pragmatic, randomized clinical superiority trial. The intervention group will receive the app and instructions on how to use it, while the control group will be allocated to a waitlist and allowed to download the app after 6 months. After inclusion, participants will be asked to complete questionnaires at baseline, 3 months, and 6 months. The primary outcome is the number of NSSI episodes during the preceding month, as measured at the 6 months follow-up with the Deliberate Self-Harm Inventory. A total of 280 participants, 140 in each arm, will be included.

DISCUSSION

This trial will assess the effectiveness of the Zero Self-Harm intervention to reduce the number of NSSI episodes. If effective, the app will have the potential to support a large group of people with NSSI. Considering the stigma related to NSSI, the fact that the app may be used in private and anonymously might make it an appealing and acceptable option for support. The app was developed in collaboration with people with lived experiences related to current and/or previous NSSI. As a result of this, the app focuses on minimizing harm, rather than stopping NSSI. This might enhance its utilization.

Measurement and stratification of nonsuicidal self-injury in adolescents

BACKGROUND

Nonsuicidal self-injury (NSSI) is highly prevalent in adolescents. In survey and interview studies assessing NSSI, methods of assessment have been shown to influence prevalence estimates. However, knowledge of which groups of adolescents that are identified with different measurement methods is lacking, and the characteristics of identified groups are yet to be investigated. Further, only a handful of studies have been carried out using exploratory methods to identify subgroups among adolescents with NSSI.

METHODS

The performance of two prevalence measures (single-item vs. behavioral checklist) in the same cross-sectional community sample (n = 266, age M = 14.21, 58.3% female) of adolescents was compared regarding prevalence estimates and also characterization of the identified groups with lifetime NSSI prevalence. A cluster analysis was carried out in the same sample. Identified clusters were compared to the two groups defined using the prevalence measures.

RESULTS

A total of 118 (44.4%) participants acknowledged having engaged in NSSI at least once. Of these, a group of 55 (20.7%) adolescents confirmed NSSI on a single item and 63 (23.7%) adolescents confirmed NSSI only on a behavioral checklist, while denying NSSI on the single item. Groups differed significantly, with the single-item group being more severely affected and having higher mean scores on difficulties in emotion regulation, self-criticism, number of methods, higher frequency of NSSI, higher rates of suicidal ideation and suicidal behavior and lower mean score on health-related quality of life. All cases with higher severity were not identified by the single-item question. Cluster analysis identified three clusters, two of which fit well with the groups identified by single-item and behavioral checklist measures.

CONCLUSIONS

When investigating NSSI prevalence in adolescents, findings are influenced by the researchers' choice of measures. The present study provides some directions toward what kind of influence to expect given the type of measure used, both with regards to the size of the identified group and its composition. Implications for future research as well as clinical and preventive work are discussed.

Friendship and self-harm: a retrospective qualitative study of young adults' experiences of supporting a friend who self-harmed during adolescence

Introduction

Self-harm amongst young people is becoming increasingly prevalent. Understanding, responding to, and supporting young people who self-harm is vital. Friends are typically the first and sometimes the only source of support sought by adolescents who self-harm. Despite their important role as confidants, friends' perspectives and experiences remain poorly understood.

Methods

We conducted retrospective qualitative semi-structured interviews, prompted by an adapted version of the Card Sort Task for Self-Harm (CaTS-FF), about the experiences of nine female young adults (18-20 years old) who supported a friend who self-harmed during adolescence. Data were analyzed using thematic analysis.

Results

Four themes were developed: (1) "I did not realize my friend was on the road to self-harm": Friends' reactions to self-harm; (2) "That's what friends do": the role of friends; (3) The impact of supporting a friend who self-harms; and (4) "They were quite formative years": reflecting on growth through the experience.

Discussion

The present findings highlight the complex experiences of young people supporting a friend who self-harms. Despite being willing to take on the role of a supporter, participants experienced a range of difficult emotions and consequences. The temporal transition running through the four themes reflects the evolving nature of participants' attitudes, knowledge, and friendships. Overall, results highlight the unmet needs of adolescents supporting young people who self-harm, as well as identifying potential pathways to "support the supporters" toward resilience.

Non-suicidal Self-injurious Thoughts and Behaviors Among Adolescent Inpatients

Non-suicidal self-injury (NSSI) is a serious public health concern that typically onsets during early adolescence. Adolescents (N = 980, ages 12-19 years) admitted for acute, residential psychiatric treatment completed baseline clinical interviews assessing mental disorders and questionnaires measuring demographics, early life adversity, and symptom severity. Prevalence rates of NSSI for lifetime (thoughts: 78%; behaviors: 72%), past year (thoughts: 74%; behaviors: 65%), and past month (thoughts: 68%; behaviors: 51%) were high. Although effect sizes were modest, the presence of a lifetime depressive disorder, sexual abuse, and comorbidity (i.e., three or more current disorders) were significant correlates of experiencing NSSI thoughts and behaviors. Furthermore, lifetime depressive disorder, current anxiety disorder, and comorbidity were associated with a greater odds of persistent NSSI thoughts and/or behaviors. Longitudinal studies are needed to determine whether targeting these factors reduces the persistence of NSSI thoughts and behaviors.

[Prevalence and risk factors of non-suicidal self-injury behavior]

The prevalence of non-suicidal self-injury (NSSI) behavior in adolescents has increased significantly in the early 21st century. The phenomenon of NSSI behavior has become one of the key health problems in the field of adolescent psychiatry and psychology over the past decade worldwide. However, the social characteristics and factors influencing NSSI are very different in different regions of the world. Studies of self-harming behavior indicate that the upward trend is almost equally relevant for developing and developed countries. To date, the methodological basis for the diagnosis of NSSI has not been sufficiently developed in the Russian Federation, there are only some studies of NSSI both from an empirical perspective and in the context of the search for risk factors, causes and functions, models of comorbidity with mental disorders.

Trauma-Informed Approach to Qualitative Interviewing in Non-Suicidal Self-Injury Research

Non-suicidal self-injury (NSSI) is recognized as a public health concern owing to its chronic nature, association with suicide risk, and its growing prevalence rates across the globe. Including individuals living with NSSI in research is crucial as it offers opportunities to give primacy to participant voices and insights, further guiding therapeutic interventions. Research has established an association between history of traumatic events and adverse childhood experiences with subsequent risk of NSSI. When planning a qualitative research study with individuals with potential trauma history, researchers need to be aware of and sensitive to potential re-traumatization and distressing emotions that participants may experience during interviews, as well as complex trauma reactions that may affect individuals after study participation. The article emphasizes that researchers be cognizant of the multifaceted nature of trauma and how it can impact individuals and communities and be sensitive in their approach to interviewing vulnerable groups such as individuals with experiences of NSSI. The authors propose adopting a trauma-informed approach to ethically plan and conduct qualitative interviews exploring NSSI experiences. Trauma-informed recommendations for preparing and carrying out specific steps during different stages of NSSI interviews are detailed.

Attitudes toward and experiences of clinical and non-clinical services among individuals who self-harm or attempt suicide: a systematic review

The prevalence of self-harm has increased substantially in recent decades. Despite the development of guidelines for better management and prevention of self-harm, service users report that quality of care remains variable. A previous systematic review of research published to June 2006 documented largely negative experiences of clinical services among patients who self-harm. This systematic review summarized the literature published since then to July 2022 to examine contemporary attitudes toward and experience of clinical and non-clinical services among individuals who self-harm and their relatives. We systematically searched for literature using seven databases. Quality of studies was assessed using the Mixed-Methods Appraisal Tool and findings were summarized using a narrative synthesis. We identified 29 studies that met our inclusion criteria, all of which were from high- or middle-income countries and were generally of high methodological quality. Our narrative synthesis identified negative attitudes toward clinical management and organizational barriers across services. Generally, more positive attitudes were found toward non-clinical services providing therapeutic contact, such as voluntary sector organizations and social services, than clinical services, such as emergency departments and inpatient units. Views suggested that negative experiences of service provision may perpetuate a cycle of self-harm. Our review suggests that in recent years there has been little improvement in attitudes toward and experiences of services for patients who self-harm. These findings should be used to reform clinical guidelines and staff training across clinical services to promote patient-centered and compassionate care and deliver more effective, acceptable and accessible services.

The pooled prevalence and influential factors of non-suicidal self-injury in non-clinical samples during the COVID-19 outbreak: A meta-analysis

BACKGROUND

COVID-19 has had an enormous impact on the mental health of people around the world, particularly adolescents. Non-suicidal self-injury (NSSI) is one of the most prominent and dangerous behaviors associated with suicide. However, few meta-analyses of the NSSI prevalence have ever been conducted since the COVID-19 outbreak. Here, we conducted a meta-analysis to estimate the pooled prevalence and elucidate the influencing factors for NSSI.

METHODS

We searched PubMed, Web of Science, Embase, APA PsycINFO, CNKI and Wanfang Database for relevant literature published before April 2022. Pooled prevalence and 95 % confidence interval (CI) were used to assess NSSI prevalence. Subgroup and meta-regression analyses were performed to clarify the potential influencing factors.

RESULTS

A total of 15 studies with 24,055 participants were eventually included. The results showed that the pooled overall prevalence of NSSI among overall samples during the COVID-19 pandemic was 22.5 % (95 % CI: 17.2 % to 28.9 %). Subgroup and meta-regression analyses revealed that the crucial influencing factors for NSSI included gender, age, regional distribution, and suicidal ideation. Specifically, the NSSI prevalence among adolescents and adults during the pandemic was 32.40 % and 15.70 %, respectively. Most importantly, gender is a significant influencing factor for NSSI among adolescents.

CONCLUSIONS

The pooled prevalence of NSSI during the COVID-19 outbreak has surged to alarming heights, especially among adolescents. The prevalence of NSSI may be influenced by complex factors such as gender and age. Therefore, it is critical to pay attention to NSSI behaviors in the adolescent population, particularly male adolescents who appear to be susceptible.

Workplace Objectification Leads to Self-Harm: The Mediating Effect of Depressive Moods

In the current research, we aimed to extend the literature on workplace objectification and contribute to employees' well-being by exploring whether and how workplace objectification increases self-harm as well as the coping strategy that may weaken the effect. Employing archive data analytic, correlational, longitudinal, and experimental designs, we found that workplace objectification was associated with, or led to, self-harm, irrespective of whether such actions provided an escape from work. This effect could not be simply ascribed to the negative nature of workplace objectification. We further found that depressive moods mediated this effect. The detrimental effect of workplace objectification on self-harm was lessened when employees perceived higher alternatives in life. Theoretical and managerial implications were discussed.

Risk and protective factors for self-harm in adolescents and young adults: An umbrella review of systematic reviews

We conducted an umbrella review to synthesise the evidence from systematic reviews and meta-analyses that examined the risk and protective factors for self-harm in young people. We searched six different databases and used the AMSTAR-2 checklist for quality assessment. The importance of each risk and protective factor was determined based on (1) the number of times it was identified by general reviews examining any risk or protective factor, and (2) the effect sizes from meta-analyses. There were 61 systematic reviews included in this review. The most frequently identified risk factors for self-harm in young people included childhood abuse, depression/anxiety, bullying, trauma, psychiatric illnesses, substance use/abuse, parental divorce, poor family relationships, lack of friends, and exposure to self-harm behaviour in others. The risk factors with the strongest evidence for an association with self-harm were behavioural disorders, personality disorders and depression or anxiety. There was a dearth of systematic reviews examining protective factors but good family/friend relationships were most frequently identified. There was also evidence to show that non-suicidal and suicidal self-harm shared many of the same risk factors. Clinicians and other professionals who work with young people should be particularly cognisant of the psychiatric and adverse life event risk factors as well as the substance use, education-related and individual-level (e.g. being LGB) risk factors for self-harm. Knowledge of risk factors for self-harm can potentially be used to inform the design and implementation of prevention measures and further research is needed on the protective factors for self-harm.

A preliminary investigation into cortical structural alterations in adolescents with nonsuicidal self-injury

The structural neural correlates underlying youth nonsuicidal self-injury (NSSI) warrant further exploration. Few studies have explored the association between NSSI and brain structure in adolescence, and no studies have investigated differences in the relation between age and brain structure in youth with NSSI. This preliminary investigation examined associations between NSSI history, age, and cortical structure using magnetic resonance imaging in adolescent girls (N=100, Mage=13.4 years) at increased risk for psychopathology. We conducted whole-brain analyses to investigate the associations between age and cortical structure, NSSI history and cortical structure, and NSSI history as a moderator of the association between age and cortical structure. Results suggested that age was associated with less cortical thickness and surface area in the left and right prefrontal, temporal, and parietal cortex. NSSI history was associated with less left insula and left inferior parietal cortex cortical surface area. Among adolescents with NSSI history, older age predicted greater left inferior parietal cortex surface area and was not associated with left precentral cortex surface area. Among adolescents without NSSI history, older age predicted smaller surface areas as expected with the typical trajectory of neurodevelopment. Overall, our results suggest differences in cortical surface area development in adolescents with NSSI history.

School-based self-harm prevention programs: A systematic review with implications for international implementation

Both self-harm and suicidal behaviors have been targeted through school-based prevention programs, many of which have been developed in the United States. The aims of this systematic review were to assess effects of school-based prevention programs on suicide and self-harm and to evaluate whether they are fit to the exporting culture. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Our inclusion criteria, structured according to population/problem, intervention, control/comparison, outome, were: children and youth up to 19 years of age, school-based programs at universal, selective or indicated levels compared with teaching as usual or with other programs, and outcomes of suicide or self-harm measured at least 10 weeks after intervention. Studies without a control group or using non-behavioral outcomes were excluded. A comprehensive and systematic literature search was conducted from the 1990s to March 2022. Risk for bias was assessed with checklists adapted from the Cochrane Risk of Bias (ROB) tool. A total of 1,801 abstracts were retrieved. Five studies fulfilled our inclusion criteria, but one had high risk for bias. Confidence in the evidence for effect was assessed with Grading of Recommendations Assessment, Development and Evaluation (GRADE). Studies included in this review were evaluated with respect to applicability in the context of international export. Only two school-based programs demonstrated efficacy in preventing suicidal behaviors. Although implementation of evidence-based interventions is a crucial next step, further replication with simultaneous attention to dissemination and implementation issues are called for. Funding and registration: conducted on assignment by the Swedish government. The protocol is available at the SBU website in Swedish.

Frequency and predictors of individual treatment outcomes (response, remission, exacerbation, and relapse) in clinical adolescents with nonsuicidal self-injury

BACKGROUND

Nonsuicidal self-injury (NSSI) is prevalent in adolescent clinical samples. There is evidence that NSSI can be treated effectively but data on individual treatment outcomes is limited. The goal of this study was to examine response, remission, exacerbation, and relapse rates over one and two years, respectively, among a clinical sample of adolescents with NSSI. Furthermore, we aimed to identify clinically relevant predictors of NSSI trajectories.

METHODS

The sample consists of n = 203 adolescents (12-17 y., 94% female) from a specialized outpatient clinic for risk-taking and self-harming behavior with NSSI on at least five days in the six months before first assessment. Assessments were completed at baseline and one (FU1) and two (FU2) years later using structured clinical interviews and self-report questionnaires.

RESULTS

At FU1, 75% reported a reduction in NSSI frequency by at least 50% (treatment response); among those, one third (25% of the entire sample) achieved a remission (0 NSSI); an exacerbation (⩾50% more NSSI) was observed in 11% of patients. Of those in remission, 41% relapsed one year later. Predictors of non-response or non-remission were inpatient treatment and depressive symptoms. Adolescents with lower NSSI frequency at baseline had a higher risk of exacerbation. Due to limited sample size at FU2 no prediction model for relapse was established.

CONCLUSIONS

While most adolescents presenting with NSSI achieved significant improvement, more attention should be paid to the rather low rates of full remission. Prediction and early detection of individuals who deteriorate during or relapse after treatment is critical.

Suicidal Ideation and Non-Suicidal Self-Injury Following Early Childhood Psychotic Experiences in Preadolescent Children at Familial High Risk of Schizophrenia or Bipolar Disorder-The Danish High Risk and Resilience Study, VIA 11

BACKGROUND AND HYPOTHESIS

Suicide is a leading cause of death in youth and is often preceded by suicidal ideation (SI) and non-suicidal self-injury (NSSI). Identifying early markers of risk for SI and NSSI could improve timely identification of at-risk individuals.

STUDY DESIGN

Children (mean age 11.9, SD 0.2) at familial high risk of schizophrenia (N = 171), or bipolar disorder (N = 104), and controls (N = 174) were assessed for psychotic experiences (PE), SI, NSSI, and Axis I mental disorders in face-to-face interviews in early and middle childhood (age 7 and 11).

STUDY RESULTS

Having 2 types of early childhood PE predicted middle childhood SI after accounting for previous SI, NSSI, and mental disorders (OR 2.8, 95% CI 1.1-6.9; P = .03). Two PE predicted NSSI (OR 3.0, 95% CI 1.2-7.7; P = .02) in excess of previous SI, NSSI, mental disorders, and familial risk. Persistent and incident PE predicted SI (OR 3.2, 95% CI, 1.1-8.8; P = .03; OR 3.8, 95% CI, 1.3-11.5; P = .02) in the fully adjusted model. Nineteen percent of children with persistent PE reported middle childhood SI vs 3.8% of those who never reported PE. In children with early childhood mental disorders, those who reported 2 PE had 4.4-fold increased odds of later SI (95% CI, 1.2-16.7; P = .03) after adjustments. PE were nondifferentially associated with outcomes across familial risk groups.

CONCLUSIONS

Early childhood PE index elevated risk for subsequent SI and NSSI beyond what can be attributed to presence of mental disorders. Mental health screenings and clinical assessments should include early childhood PE.

Age of first self-harm act in childhood and adolescence: A scoping review protocol

Background

Self-harm in youth is associated with adverse outcomes for many. The age of first self-harm is not often reported in the literature and there is considerable heterogeneity in how it is reported and in the methods used to estimate it. The objective of this study will be to examine the age of first self-harm act in childhood and adolescence and to identify the research methods used to assess this.

Methods

This scoping review will follow JBI guidance. Five electronic databases, Medline, PsycInfo, CINAHL Plus, Embase, and Web of Science will be searched from inception. Grey literature will be searched via Google Scholar. Studies reporting the age of first act of self-harm in young people aged 17 years and younger are of interest. Any study design and methodology will be eligible for inclusion. Included studies may use any self-harm definition, any measures used to assess self-harm and the age of the first act. The focus can be in any context, including health services presenting or community samples. Title and abstract screening and full text screening will be carried out by two reviewers independently. The data extraction tool will be piloted by two reviewers independently, included studies will undergo data extraction by one reviewer and this will be checked by a second, independent reviewer.

Results

The resulting data will be presented using descriptive statistics, in tabular format, and accompanied with a narrative presentation of results. The results of this study will be distributed by publication in an academic journal.

The Effect of Mental Health Status and Family Function on Nonsuicidal Self-Injury: A Longitudinal Analysis of Chinese Children and Adolescents

Background

Nonsuicidal self-injury (NSSI) is an overwhelming social problem in children and adolescents. Focusing on the change of NSSI behavior, including onset, cessation, and maintenance, is crucial to developing effective prevention and intervention strategies. This study explored the effect of mental health status (depressive and anxiety symptoms) and family function on NSSI.

Methods

The study sample comprised 7554 children and adolescents based on the first two rounds of the Chengdu Positive Child Development (CPCD) dataset in China. Depressive and anxiety symptoms measured mental health status. The self-reported questionnaires also assessed NSSI behaviors and family function. The interrelationship between NSSI behaviors, mental health status, and family function was evaluated. Logistic regression and linear regression were performed to examine the interrelationship between mental health status, family function and NSSI behaviors. Sensitivity analysis was performed.

Results

In this study, 2167 (28.69%) participants reported NSSI at baseline and 2101 (27.81%) at follow-up. Depression, anxiety, and family function were salient influential factors in the prevalence, onset, and cessation of NSSI. Parents' accompaniment showed a significant effect on the prevalence of NSSI.

Conclusion

Depression, anxiety, family function, and parents' accompaniment are all associated with NSSI behaviors. Strategies targeting mental health status and family function could effectively protect children and adolescents from NSSI behaviors.

Associations Between Nonsuicidal Self-Injury and School-Based Health-Promotive Factors for Sexual and Gender Minority Youth and Their Peers

Purpose: The purpose of this study was to identify associations between school-based, health-promotive factors and nonsuicidal self-injury (NSSI) for sexual and gender minority youth and their heterosexual and cisgender peers. Methods: Using data from the 2019 New Mexico Youth Risk and Resiliency Survey (N = 17,811) and multilevel logistic regression to account for school-based clustering, we compared the effect of four school-based health-promotive factors on NSSI for stratified samples of lesbian/gay, bisexual, and gender-diverse (hereafter, gender minority [GM]) youth. Interactions were examined to evaluate the impact of school-based factors on NSSI for lesbian/gay, bisexual, (compared with heterosexual) and GM (compared with cisgender) youth. Results: Stratified analyses showed that three school-based factors (adult at school who listens, adult at school who believes they will be successful, clear school rules) were associated with lower odds of reporting NSSI for lesbian/gay and bisexual youth, but not GM youth. Interaction effects showed that lesbian/gay youth demonstrated greater reductions in odds of NSSI when reporting school-based supports compared with heterosexual youth. Associations between school-based factors and NSSI were not significantly different for bisexual compared with heterosexual youth. GM youth appear to experience no health-promotive effect on NSSI of school-based factors. Conclusions: Our findings underscore the potential of schools to provide supportive resources that reduce the odds of NSSI for most youth (i.e., heterosexual and bisexual youth), but are particularly effective in reducing NSSI among lesbian/gay youth. However, more study is needed to understand the potential impact of school-based health-promotive factors on NSSI for GM youth.

Universal prevention for non-suicidal self-injury in adolescents is scarce - A systematic review

Non-suicidal self-injury (NSSI) during adolescence is a high-risk marker for the development and persistence of mental health problems and has been recognized as a significant public health problem. Whereas targeted prevention has indeed shown to be effective in reducing NSSI and improve mental health problems, access to such programs is limited. By face validity, universal prevention of NSSI seems an ideal starting point for a stepped-care model to circumvent a lack of resources in the medical care system. However, it is yet unclear how effective such approaches are. Here, we provide a summary of existing work on universal prevention of NSSI in adolescents younger than 21 years based on a systematic literature search. We found that only seven studies are available. None of the programs evaluated was found to be effective in reducing the incidence or frequency of NSSI. After providing a comprehensive summary of the existing work, we evaluate the fact that existing work primarily focusses on selected/targeted prevention and on psychoeducational methods. We derive implications for future directions in the field of universal prevention of NSSI.

Mental health disorders, functioning and health-related quality of life among extensively hospitalized patients due to severe self-harm - results from the Extreme Challenges project

Background

Severe self-harm leading to extensive hospitalization generates extreme challenges for patients, families, and health services. Controversies regarding diagnoses and health care often follow. Most evidence-based treatments targeting self-harm are designed for borderline personality disorder (BPD). However, current knowledge about mental health status among individuals with severe self-harm is limited.

Objectives

To investigate psychopathology among patients extensively hospitalized due to severe or frequent self-harming behaviors.

Method

A cross sectional study (period 2019-2021) targeting psychiatric inpatients (>18 years) with frequent (>5) or long (>4 weeks) admissions last year due to self-harm. The target sample (N = 42, from 12 hospitals across all Norwegian health regions) was compared to individuals admitted to outpatient personality disorder (PD) treatment within specialist mental health services in the same period (N = 389). Clinicians performed interviews on self-harm and psychopathology, supplemented by self-report.

Results

The target sample were young adults, mainly female, with considerable hospitalization and self-harming behaviors, both significantly more extensive than the comparison group. The majority in both groups reported self-harm onset <18 years. The target sample reported increasing severity of self-harm acts and suicidal intention over time. Both samples had high levels of childhood trauma, impaired personality functioning, and a majority fulfilled criteria for PD. In the target sample, comorbid depression, PTSD, anxiety disorders, and substance use occurred more frequently and in 50%, psychosis/dissociative disorder/autism spectrum disorder/ADHD was reported (outpatient comparison sample: 9%). 35% in the target sample screened over cut-off for possible intellectual disability. The target sample reported poor psychosocial functioning and health-related quality of life - greater impairment than the outpatient comparison sample.

Conclusion

The study reveals that severe self-harm inpatients have complex psychopathology and highlights the importance of individualized and thorough assessment among patients with severe and/or repetitive self-harm.

The development of Non-Suicidal Self-Injury (NSSI) during adolescence: A systematic review and Bayesian meta-analysis

BACKGROUND

Despite a surge in research on self-injury in the last decade, a summary of research findings about the development of Non-Suicidal Self-Injury (NSSI) over time in community youth samples is not yet present in the scientific literature. This study aims to summarize the empirical literature on this topic, examining both the occurrence (Study 1) and frequency (Study 2) of NSSI over time, and for this reason, a Systematic Review and Bayesian Meta-Analysis were conducted.

METHODS

Following the PRISMA guidelines, the longitudinal studies included in the systematic review consisted of 41 papers (Study 1 = 16; Study 2 = 25). Only studies with available data were included in the meta-analysis (Study 1 = 12; Study 2 = 11).

RESULTS

First, the findings highlight limits related to methodological aspects, the design of the studies, and the availability of data. Meta-analytic results shows that across development, the frequency (i.e., not the occurrence) of NSSI increases for the group of younger adolescents, remains stable in the group of middle adolescents, and it decreases for older adolescents.

LIMITATIONS

This study highlights some limitations that can be summarized in three different macro categories: the first refers to methodological aspects (e.g., the lifetime prevalence of NSSI), the second to the design of the studies (e.g., not homogeneous cohort; short-term covered), and the third to the availability of data.

CONCLUSIONS

The current meta-analysis tries to shed light on the longitudinal research on NSSI behavior and how this behavior develops in terms of both occurrence and frequency, providing practical and methodological indications for future research.

Parenting in the early years and self-harm in adolescence: The role of control and reward systems in childhood

BACKGROUND

Research suggests that early parenting may contribute to the development of self-harm but this has not been examined longitudinally. In this study, we explored the relationship between early parenting and self-harm in adolescence and considered whether (1) emotion regulation and (2) decision-making in childhood mediate the relationship between early parenting and self-harm.

METHOD

Using longitudinal data from the Millennium Cohort Study (MCS), we tested mediation models exploring the relationship between early parenting and self-harm in adolescence via emotion regulation and decision-making. Parenting was assessed at age 3 with measures of conflict, closeness and discipline. The trajectories of independence & self-regulation and emotional dysregulation were modelled from ages 3 to 7 years through latent growth curve analysis, with individual predicted slope and intercept values used in the mediation models. Decision-making (deliberation time, total time, delay aversion, quality of decision making, risk adjustment, risk-taking) was assessed using the Cambridge Gambling Task (CGT) at age 11.

RESULTS

In our sample (n = 11,145), we found no evidence of a direct association between early parenting and self-harm in adolescence. However, there were indirect effects of parenting (conflict and closeness) on self-harm via the slope of emotional dysregulation. Furthermore, delay aversion was positively associated with self-harm in adolescence.

LIMITATIONS

It must be acknowledged that we cannot determine causality and that self-report measures of parenting are vulnerable to several biases.

CONCLUSION

The findings support early identification and interventions for children exhibiting chronic emotional dysregulation and decision-making characterised by a bias for smaller, immediate over larger, delayed rewards.

Left with a Sisyphean task - the experiences of nurse practitioners with treating non-suicidal self-injury in the emergency department: a descriptive qualitative study

BACKGROUND

Non-suicidal self-injury (NSSI) is a prevalent phenomenon in somatic emergency departments, where nurses are the most consistent group of healthcare professionals who treat people with NSSI, which means they may affect the NSSI trajectory and help-seeking in the future. The objective of this study was to describe the experiences of nurse practitioners with treatment of people presenting with NSSI in the emergency department.

METHODS

Individual, semi-structured telephone interviews were conducted with seventeen purposefully recruited nurse practitioners from three emergency departments in the Capital Region of Denmark. Interview transcripts were analysed using inductive content analysis, as described by Graneheim and Lundman.

RESULTS

The analysis resulted in the formulation of three categories and 10 subcategories describing how nurse practitioners feel confident and competent in treating physical injuries due to NSSI but at the same time insecure about how to provide adequate care and engage in conversations about NSSI and mental wellbeing with people with NSSI. An overarching theme, 'Left with a Sisyphean task', reflects the nurses' feeling of being handed the responsibility for performing a laborious, never-ending, and futile task.

CONCLUSION

The findings indicate that nurse practitioners feel confident and competent in treating physical injuries due to NSSI but insecure about how to provide adequate care. Therefore, there is a need for training and guidelines.
