Nonsuicidal Self-injury: A Systematic Review

Police Contact, Non-Suicidal Self-Injury, and Suicidal Ideation: Findings From a National Sample of Canadian Adolescents and Young Adults

BACKGROUND AND OBJECTIVES

The purpose of this research is to investigate associations between police contact, non-suicidal self-injury (NSSI), and suicidal ideation (SI) among a national sample of Canadian adolescents and young adults (ages 16-30).

METHODS

Data used in this study were obtained from the Canadian Study of Adolescent Health Behaviors (N = 940), a national survey of Canadians ages 16-30.

RESULTS

Police contact was associated with higher odds of NSSI (OR = 1.98, 95% CI = 1.37, 2.86). Those who reported police contact with intrusion (OR = 2.39, 95% CI = 1.49, 3.38) and police contact with harassment (OR = 3.98, 95% CI = 2.30, 6.88) had higher odds of NSSI relative to respondents with no contact. Finally, any police contact was associated with higher odds of SI (OR = 1.56, 95% CI = 1.04, 2.34) and respondents experiencing police stops with harassment had higher odds of SI compared to those who had never been stopped (OR = 2.48, 95% CI = 1.45, 4.24).

CONCLUSIONS

Distressing police contact heightens the risk of NSSI and SI among young people. Rigorous evaluation of trauma-informed, developmentally appropriate strategies for identifying and intervening on NSSI and SI following adverse police encounters should be prioritized.

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.

The Global Prevalence of Non-suicidal Self-injury, Suicide Behaviors, and Associated Risk Factors Among Runaway and Homeless Youth: A Meta-analysis

A meta-analysis was performed to determine pooled prevalence of non-suicidal self-injury (NSSI), suicide behaviors (including ideation, attempts), and associated risk factors among runaway and homeless youth (RHY). The databases PubMed, Scopus, Web of Science, and Cochrane Library were searched for relevant studies published from January 1995 to May 2023. Initially, 8465 papers were screened, resulting in 69 included studies. The results showed that among RHY, lifetime prevalence rates were 42% for NSSI, 38% for suicidal ideation, and 27% for suicide attempts. Lifetime prevalence of NSSI and suicide behaviors was higher among adolescent minors (aged 12-17 years) compared to young adults (aged 18-24 years). Also, NSSI and suicide behaviors were associated with having a childhood history of physical and sexual abuse. Developing an impactful community-based suicide prevention campaign tailored for RHY appears warranted. Peer groups and mentorship programs would provide invaluable support for young individuals, as supportive friendships protect against NSSI.

Negative self-perceptions and severity of NSSI: Testing the benefits and barriers model

Nonsuicidal self-injury (NSSI) is theorized to be caused by negative associations with the self, including low self-esteem, but the mechanisms explaining why low self-esteem is related to more severe NSSI are unclear. The current study aimed to address this limitation by evaluating a mediation model, proposing that low self-esteem would relate to more severe NSSI through increasing self-punishment motivations. Data came from 468 undergraduate students with a history of NSSI who completed an online survey measuring NSSI characteristics and functions, self-esteem, and self-punishment motivations for NSSI. Mediation was tested using a structural equation model using bootstrapped 95% percentile-corrected confidence intervals in which NSSI severity was modeled as a latent variable composed of NSSI frequency, recency, and versatility of methods. The total model was significant and the indirect effect of self-esteem on NSSI severity through self-punishment motives was significant. Self-esteem also retained significant direct effects on NSSI severity, indicating partial mediation. These results provide support for the benefits and barriers model of NSSI, suggesting that negative self-views increase risk for more severe NSSI through self-punishment motivations. Clinical interventions that emphasize self-compassion and focus on modifying self-punishment motivations may help reduce NSSI behavior.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Impact of an injury hospital admission on childhood academic performance: a Welsh population-based data linkage study

BACKGROUND

While injuries can impact on children's educational achievements (with threats to their development and employment prospects), these risks are poorly quantified. This population-based longitudinal study investigated the impact of an injury-related hospital admission on Welsh children's academic performance.

METHODS

The Secure Anonymised Information Linkage databank, 55 587 children residing in Wales from 2006 to 2016 who had an injury hospital admission (58.2% males; 16.8% born in most deprived Wales area; 80.1% one injury hospital admission) were linked to data from the Wales Electronic Cohort for Children. The primary outcome was the Core Subject Indicator reflecting educational achievement at key stages 2 (school years 3-6), 3 (school years 7-9) and 4 (school years 10-11). Covariates in models included demographic, birth, injury and school characteristics.

RESULTS

Educational achievement of children was negatively associated with: pedestrian injuries (adjusted risk ratio, (95% CIs)) (0.87, (0.83 to 0.92)), cyclist (0.96, (0.94 to 0.99)), high fall (0.96, (0.94 to 0.97)), fire/flames/smoke (0.85, (0.73 to 0.99)), cutting/piercing object (0.96, (0.93 to 0.99)), intentional self-harm (0.86, (0.82 to 0.91)), minor traumatic brain injury (0.92, (0.86 to 0.99)), contusion/open wound (0.93, (0.91 to 0.95)), fracture of vertebral column (0.78, (0.64 to 0.95)), fracture of femur (0.88, (0.84 to 0.93)), internal abdomen/pelvic haemorrhage (0.82, (0.69 to 0.97)), superficial injury (0.94, (0.92 to 0.97)), young maternal age (<18 years: 0.91, (0.88 to 0.94); 19-24 years: 0.94, (0.93 to 0.96)); area based socioeconomic status (0.98, (0.97 to 0.98)); moving to a more deprived area (0.95, (0.93 to 0.97)); requiring special educational needs (0.46, (0.44 to 0.47)). Positive associations were: being female (1.04, (1.03 to 1.06)); larger pupil school sizes and maternal age 30+ years.

CONCLUSION

This study highlights the importance on a child's education of preventing injuries and implementing intervention programmes that support injured children. Greater attention is needed on equity-focused educational support and social policies addressing needs of children at risk of underachievement, including those from families experiencing poverty.

"Swipe & slice": decoding digital struggles with non-suicidal self-injuries among youngsters

Introduction

Nonsuicidal-self-injury (NSSI)-related content recently emerged on social networking sites (SNS), despite its relationship with NSSI conducts is still unclear.

Methods

Hence, the current population-based cross-sectional study investigated the interplay between SNS use, NSSI content engagement, risky social media challenges (RSMCs), in a sample of 404 young adults (aged 18-24), focusing on the influence of problematic social media use (PSMU) and fear of missing out (FoMO).

Results

Around 51.5% of the samplewas engaged inNSSI-related contents on SNS, being mostly females (p<0.001), younger (p=0.005), transgender people and nonbinary people (p=0.030) and those who displayed higher PSMU (p<0.001) or FoMO (p=0.031). Around 66.2% of the sample currently practice NSSIs, predominantly among females (p<0.001), those using BeReal (p=0.012), actively looking for NSSIrelated contents on SNS (p<0.001) to be part of a group (p=0.0025) or learn how to practice NSSI (p=0.025). PSMU (p<0.001) and FoMO (p<0.001) emerged as significant predictors of NSSI content engagement, particularly among active seekers. NSSI conducts were significantly predicted by FoMO (p<0.001) and Snapchat (p=0.044), while negatively predicted by male sex (p<0.001), higher educational level (p=0.019) and age at which NSSI-related contents were firstly looked for (p=0.028).

Discussion

These findings underline the need to implement preventivepolicies and targeted interventions to monitor NSSI-related contents on SNS, the impact of PSMU and FoMO on NSSI, particularly among youngsters.

The role of cognitive disengagement syndrome in non-suicidal self-injury among adolescents with attention deficit hyperactivity disorder

AIMS

We aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) and non-suicidal self injury (NSSI) in adolescents with attention deficit hyperactivity disorder (ADHD).

METHODS

A semi-structured psychiatric interview and an NSSI screening questionnaire were conducted. Questionnaires assessing CDS (with daydreamer, sleepy, and slow subdimensions), depression, anxiety, self-esteem, emotion regulation, coping strategies, and loneliness were administered.

RESULTS

Among 104 participants (n: 63, 60.6% girls), the combined type of ADHD was the most common (66.3%), and 35 adolescents (27 girls) were in the NSSI+ group. Although only depression and ADHD were found to be predictors of NSSI in ADHD, CDS was associated with many risk factors of NSSI in ADHD: depression, anxiety, emotion dysregulation, low self-esteem, and emotion-oriented coping ways. After controlling for the effects of cognitive problems/inattentiveness, depression, and anxiety, CDS still correlated with low self-esteem and emotion dysregulation. The daydreamer and slow sub-dimensions of CSD differed between NSSI+ and NSSI- groups, while sleepy did not.

CONCLUSIONS

CDS is associated with several relevant factors, indirectly relating it to self-harm in ADHD. CDS increases the vulnerability to mental health changes that could lead to NSSI in adolescence with ADHD.

Adolescent Nonsuicidal Self-Injury and Suicidality: A Latent Class Analysis and Associations with Clinical Characteristics in an At-Risk Cohort

Nonsuicidal self-injury (NSSI) is frequently encountered in adolescents, but its predictive value for suicidality or other clinical characteristics is challenging due to its heterogeneous nature. This study used latent class analysis to identify subgroups of NSSI and compared these on sociodemographic characteristics, adverse outcomes and protective factors. The study included 966 high-risk adolescents, Mage 14.9 y, SD 0.9 y, 51.8% female. Four classes emerged: (1) "Low NSSI-Low suicidality", (2) "Moderate NSSI-Low suicidality", (3) "Moderate NSSI-High suicidality", and (4) "High NSSI-High suicidality". Girls predominated in the high suicidality classes. Generally, Class 4 had the poorest outcomes: more internalizing and externalizing problems, less social support from friends and families and worst self-esteem. These findings emphasize the need for interventions tailored to specific phenotypes of adolescents engaging in NSSI.

Interrupting the Self-Harm Continuum

Background: Nonsuicidal self-injury (NSSI) has increased rapidly and is frequently linked to suicidal behavior; it has been argued that these behaviors are key points on a self-harm continuum. Aims: The current research explored self-harm and help-seeking behaviors, with the aim of identifying possibilities for prevention of further harm, including suicide. Methods: An online survey of 304 New Zealanders was undertaken, with the majority being aged under 25 and female. Results: Nearly half of the sample had engaged in self-harm and most of those had experienced suicidal thoughts; close to a quarter had made a suicide attempt. NSSI was used as a way of dealing with emotional distress. Very few sought help of any kind, especially professional support; of those who did seek professional support, most found it helpful but did not necessarily stop self-harming as a result. Limitations: Men are under-represented in the sample - though this is in accordance with the population of people who engage in NSSI. Conclusion: Many participants engaged in NSSI and also had suicidal thoughts using NSSI as an emotion regulation strategy; some participants appeared to use NSSI rather than attempting suicide. Given a link between NSSI and suicidal thoughts and behaviors, reluctance to seek help and on-going injurious behavior among some who do seek help, there is a need for increased identification and proactive support specifically focusing on improving emotion regulation and targeted at injurious behavior.

Different self-damaging behaviours, similar motives? Testing measurement invariance of motives for nonsuicidal self-injury, disordered eating and substance misuse

OBJECTIVES

Theory and research suggest that distinct self-damaging behaviours (SDBs; e.g., nonsuicidal self-injury [NSSI], restrictive eating, binge eating, drug misuse, alcohol misuse) share similar motives. However, few studies have used a common self-report inventory to investigate the shared relevance and relative salience of motives for SDBs. Accordingly, the present study: (1) examined whether self-report scales assessing intrapersonal motives (i.e., relieving negative emotions, enhancing positive emotions, punishing oneself) and interpersonal motives (i.e., bonding with others, conforming with others, communicating distress, communicating strength, reducing demands) have invariant factor structures across SDBs; and (2) compared the salience of these motives across SDBs.

METHODS

1018 adults (54.6% men, Mage = 35.41 years) with a history of SDBs were allocated to the following groups: NSSI (n = 213), restrictive eating (n = 200), binge eating (n = 200), drug misuse (n = 200) or alcohol misuse (n = 205). Participants reported on their motives for engaging in their allocated SDB. Measurement invariance analyses compared the factor structures and latent means of the motive scales across SDBs.

RESULTS

The motive scales had comparable factor structures across SDBs. Intrapersonal motives were most strongly endorsed for NSSI and drug misuse. Interpersonal motives were most strongly endorsed for drug and alcohol misuse. All motives were least salient to restrictive eating.

CONCLUSIONS

Results suggest that common motives underlie distinct SDBs and that they can be adequately assessed using a single self-report inventory. However, certain motives are more relevant to some SDBs than others, with restrictive eating being the most motivationally distinct SDB. This knowledge can inform transdiagnostic models and interventions for SDBs.

Suicidality and Non-Suicidal Self-Injury: A Narrative Review of Measurement, Risk, and Disparities among Minoritized and System-Involved Youth in the USA

Suicidality and non-suicidal self-injury (NSSI) among youth in the United States continue to be a growing and serious public health concern. With alarming rates of suicide trending in the wrong direction, researchers are committed to bending the curve of suicide and reducing rates by 2025. Understanding the antecedents and conditions, existing measures, and disparate prevalence rates across minoritized groups is imperative for developing effective strategies for meeting this goal. This study presents a narrative review of the operationalization, measurement, risk factors (e.g., firearms and social media), and disparities across race, ethnicity, age, gender identity, ability, sexual orientation, immigration statuses, and system involvement (e.g., foster care and juvenile justice) of suicidality and non-suicidal self-harm across youth in the United States. Implications for research, practice, and policy approaches that incorporate positive youth development, cultural, and youth participation in interventions are discussed.

The Relationship Between Childhood Trauma and Non-Suicidal Self-Injury Behavior in Adolescents with Depression: The Mediating Role of Rumination

Objective

Non-suicidal self-injury (NSSI) behavior is very common in adolescents with depression, and childhood trauma is considered one of the distal risk factors for its exacerbation. Rumination caused by adverse traumatic experiences, which can be transferred through NSSI behavior, can alleviate symptoms of depression in adolescents. The current research focuses on the relationship between the three, further exploring whether rumination is a mediator in the relationship between childhood trauma and NSSI behavior on the basis of previous studies, and provides some suggestions for future early intervention for adolescents with depression.

Methods

A total of 833 adolescent patients with depression who met the DSM-5 criteria for depressive episode were recruited from 12 hospitals in China. The Chinese version of the Function Assessment of Self-mutilation, Childhood Trauma Questionnaire, and Rumination Inventory were used as research tools.

Results

The scores of childhood trauma and rumination in adolescents with depression in the NSSI group were higher than those in the non-NSSI group. A Pearson's correlation analysis showed that childhood trauma was positively correlated with rumination (r=0.165, P<0.01), different types of childhood trauma were significantly positively correlated with rumination and its three factors, and these results were statistically significant. Rumination partially mediated the relationship between childhood trauma and NSSI behavior in depressed adolescent patients (effect size=0.002), and the effect in female participants (effect size=0.003), was greater than that in male participants (effect size=0.002).

Conclusion

Childhood trauma and rumination were key factors for NSSI behavior in adolescents with depression. Childhood trauma not only has a direct effect on NSSI behavior in adolescent depression, but also plays an indirect effect on NSSI behavior through rumination.

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 examining hemomania behaviors in psychiatry outpatients engaged with nonsuicidal self-injury

BACKGROUND

This study aims to conduct the first-ever evaluation of our previously proposed behaviors of "hemomania" in individuals engaged with nonsuicidal self-injury (NSSI).

METHODS

The study encompassed 130 outpatients engaged with NSSI who applied at the psychiatry outpatient clinic. NSSI behaviors were assessed using the Inventory of Statements About Self-Injury, while psychiatric diagnoses were evaluated using the Structured Clinical Interview for DSM-5 Disorders-Clinician Version. Subsequently, participants completed the Depression Anxiety Stress Scale-21 and Short Form of Barratt Impulsiveness Scale.

RESULTS

The prevalence of at least one hemomania behavior including seeing blood, tasting blood, bloodletting, and blood-drinking was observed to be 43.1% in individuals with NSSI. When participants were divided into two groups, individuals with hemomania exhibited: (1) a higher incidence of psychiatric comorbidities, increased suicide attempts, and more severe symptoms of depression, anxiety, stress, and impulsivity, (2) higher comorbidity rates of borderline personality disorder, body-focused repetitive behaviors, and dissociative disorders, and (3) elevated frequencies of certain NSSI behaviors, including cutting, biting, needle-ticking, and carving, compared to those without.

CONCLUSION

Hemomania could be considered a specific impulse control disorder, characterized by heightened impulsivity and a persistent urge to obtain one's own blood. However, further studies are needed to validate this hypothesis.

Somatic multicomorbidity and disability in patients with psychiatric disorders in comparison to the general population: a quasi-epidemiological investigation in 54,826 subjects from 40 countries (COMET-G study)

BACKGROUND

The prevalence of medical illnesses is high among patients with psychiatric disorders. The current study aimed to investigate multi-comorbidity in patients with psychiatric disorders in comparison to the general population. Secondary aims were to investigate factors associated with metabolic syndrome and treatment appropriateness of mental disorders.

METHODS

The sample included 54,826 subjects (64.73% females; 34.15% males; 1.11% nonbinary gender) from 40 countries (COMET-G study). The analysis was based on the registration of previous history that could serve as a fair approximation for the lifetime prevalence of various medical conditions.

RESULTS

About 24.5% reported a history of somatic and 26.14% of mental disorders. Mental disorders were by far the most prevalent group of medical conditions. Comorbidity of any somatic with any mental disorder was reported by 8.21%. One-third to almost two-thirds of somatic patients were also suffering from a mental disorder depending on the severity and multicomorbidity. Bipolar and psychotic patients and to a lesser extent depressives, manifested an earlier (15-20 years) manifestation of somatic multicomorbidity, severe disability, and probably earlier death. The overwhelming majority of patients with mental disorders were not receiving treatment or were being treated in a way that was not recommended. Antipsychotics and antidepressants were not related to the development of metabolic syndrome.

CONCLUSIONS

The finding that one-third to almost two-thirds of somatic patients also suffered from a mental disorder strongly suggests that psychiatry is the field with the most trans-specialty and interdisciplinary value and application points to the importance of teaching psychiatry and mental health in medical schools and also to the need for more technocratically oriented training of psychiatric residents.

What Do My (Online) Friends Think? A Topic Modeling Approach to Identifying Patterns of Response to Self-Injurious Behaviors on Reddit

OBJECTIVE

Approximately 17% of adolescents and young adults will engage in non-suicidal self-injury (NSSI) at least once in their lifetime, leading the World Health Organization to identify self-injury as one of the top five public health concerns for adolescents. Despite the widespread prevalence of this behavior, NSSI continues to be heavily stigmatized in both medical and community settings, deterring many engaged in NSSI from seeking informal support from friends and family as well as formal psychological or psychiatric treatment. In contrast to the low rates of in-person help-seeking for NSSI, online support groups are highly utilized by those engaged in NSSI. Thus, an empirical study of responses to frequent, voluntary disclosure of NSSI on social media is needed to better understand how these communities meet the needs of those who self-injure.

METHOD

The current project used latent Dirichlet allocation to identify frequent and favored themes in response to self-injury content in the largest self-injury group on Reddit (over 100,000 members). Reddit, the 9th most visited website in the world, is a chat-based social media platform that has 430+ million active users and billions of site visits, with current estimates suggesting that ∼63% of the U.S. population are Reddit users.

RESULTS

Identified themes included: (1) recovery encouragement; (2) provision of social and instrumental support; and (3) daily realities of living with NSSI. Responses that encouraged recovery received more upvotes on Reddit than any other type of comment.

CONCLUSION

These results can inform evidence-based, person-centered, dimensional treatments for NSSI.

Childhood Maltreatment and Non-Suicidal Self-Injury in Adolescents: Testing a Moderated Mediating Model

There is a wealth of evidence to suggest that childhood maltreatment is a major risk factor contributing to non-suicidal self-injury (NSSI) among adolescents. However, how and under what conditions childhood maltreatment is related to NSSI remains largely unclear. This study examined the indirect effect of depressive symptoms in the relation between childhood maltreatment and non-suicidal self-injury, as well as the moderating role of cognitive reappraisal and emotion reactivity in those associations. A sample of 1,984 Chinese adolescents (Mage = 12.84, SD = 1.27, 47.9% girls) completed self-report questionnaires. The results of path analysis showed that childhood maltreatment was significantly related to NSSI and that depressive symptoms play an indirect effect in the relation between them. Cognitive reappraisal mitigated the effect of childhood maltreatment on depressive symptoms, and emotion reactivity strengthened the effect of depressive symptoms on non-suicidal self-injury. The results further showed that the indirect effect of depressive symptoms was more prominent for youths with lower levels of cognitive reappraisal and greater emotion reactivity. Interventions that enhance cognitive reappraisal and reduce emotion reactivity may interrupt the pathway from childhood maltreatment to NSSI via depressive symptoms.

Non-suicidal Self-injury and Quantified Electroencephalogram in Adolescents and Young Adults with Depression

Objective

: This study investigated the association between non-suicidal self-injury (NSSI) and quantified electroencephalogram (QEEG) in patients with depression. We aimed to identify clinical features of NSSI and differences in QEEG findings.

Methods

: This retrospective study used the medical records of 52 inpatients with major depressive episodes, aged from 15 to 30. The patients were categorized according to their history of NSSI. Their main diagnosis and sex were also considered. To evaluate clinical symptoms, self-reported scales were used. The absolute power and the Z-scores of various waves were included.

Results

: NSSI was associated with suicidal ideations (p = 0.001) and trauma history (p = 0.014). In the binary logistic regression analysis, the Z-score of absolute alpha power was higher on the FP2 node (p = 0.029), lower on the F4 node (p = 0.029) in the NSSI group. The absolute high beta power in the NSSI group was higher on the FP2 and the F3 node, but lower on the F7 and F8 node. Patients with NSSI showed higher Z-score of the absolute delta power at the FP2 node (p = 0.044). The absolute gamma power was higher on the FP2 (p = 0.012) and the F3 node (0.043), lower on the FP1 (p = 0.019) and the F7 node (0.018) in the NSSI group. The absolute high gamma power at the FP2 (p = 0.017) and F8 nodes (p = 0.045) were higher in the NSSI group.

Conclusion

: Patients with NSSI may have clinical features distinct from those of patients without NSSI. QEEG results have shown some differences, although it is less applicable due to some limitations.

A study of the interactive mediating effect of ADHD and NSSI caused by co-disease mechanisms in males and females

Background

Non-suicidal self-injury (NSSI), of which the predisposing factors are complex and diverse, profoundly affects the physical and mental health of young people. Therefore, this work established an NSSI intermediary network model considering the interaction of multiple factors. A mediating effect between attention-deficit/hyperactivity disorder (ADHD) and NSSI, considering the influence of comorbidities, such as depression, anxiety, and impulsive personality, was proposed based on sex differences.

Methods

A total of 2,689 middle school students in Ningbo City, Zhejiang Province, China, were randomly sampled and participated in this study. Data regarding their demographic characteristics, attention deficit, hyperactivity/impulsivity, NSSI, anxiety, depression, internet addiction, and other comorbid symptoms were collected and analyzed. After initially screening the data, variables were assessed for significance using a single-factor inter-group difference analytic method, and a binary logistic regression analysis was performed. The intermediary effect of factors influencing NSSI in males and females was also analyzed.

Results

The overall NSSI rate was 15.16%. The results showed that the impact of individual impulsivity characteristics (impulsiveness, the ADHD with hyperactivity/impulsivity subtype) on NSSI behavior was not significant (regression results, P > 0.05). The degree of association between ADHD with attention deficit and ADHD with comprehension deficit subtypes, and other comorbid symptoms (depression, anxiety, and internet addiction disorder) and NSSI, with odds ratios (ORs) of 7.6/6.42/436.68/3.82/1.86, and 95% bootstrap confidence intervals (CIs) of 4.64, 12.87/3.46, 12.67/137.42, 2659.13/2.32, 6.37/1.31, 2.82, respectively. The results also showed significant effects of ADHD subtypes on comorbid symptoms and the path effects of NSSI (P < 0.01). Among them, the mediating effect was the strongest when anxiety was the mediating variable, and the mediating effect of girls was higher than that of boys.

Conclusion

The results of this work demonstrated the influence of ADHD symptoms on NSSI behavior. Among patients with ADHD, patients with subtypes with obvious attention deficit characteristics were more likely to exhibit NSSI behavior, whereas the hyperactive impulse subtype had no direct impact on NSSI. We conclude that adolescent impulsivity may not be directly related to NSSI behavior and that impulsive characteristics jointly affect NSSI behavior through a series of NSSI comorbid symptoms. Notably, the probability of symptom onset and the degree of comorbidity was significantly higher in girls than in boys of the same age, and girls were more prone to NSSI behavior. These findings provide effective theoretical support for the prevention and treatment of adolescent NSSI behavior.

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.

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.

A Comparative Analysis of Emotional Regulation and Maladaptive Symptoms in Adolescents: Insights from Iran and Belgium

(1) Background: Emotional regulation is a critical determinant of adaptive functioning during adolescence, exerting a profound influence on psychological well-being. This study seeks to deepen our understanding of the intricate interplay between emotional regulation and maladaptive psychological symptoms, examining these dynamics through a cross-country comparison. (2) Methods: A total of 224 adolescents, aged 13 to 21 years, from both Iran and Belgium, participated in a cross-sectional comparative study. The study aimed to elucidate the relationship between emotional regulation and mental health functioning, assessing internalizing symptoms, externalizing symptoms, and self-injury. A demographic questionnaire, the Emotion Regulation Inventory, the Strengths and Difficulties Questionnaire, and the Self-Harm Inventory, were administered. Data analysis incorporated correlation assessments, multivariate analysis of variance, and structured equation modeling. (3) Results: The findings revealed a positive association between emotional dysregulation and psychological symptoms across the entire sample. Conversely, emotional suppression, more prevalent in Iran, showed no significant link with maladaptive symptoms but was associated with self-harm in the Belgian sample. Cultural disparities were evident, with internalizing problems more prevalent in Iran and externalizing issues more common in Belgium. (4) Conclusions: Emotional dysregulation emerged as a common factor compromising mental health. It emphasizes the necessity of considering cultural nuances when developing interventional and preventative programs and calls for further research in this field.

Young adults looking back at their experiences of treatment and care for nonsuicidal self-injury during adolescence: a qualitative study

BACKGROUND

Nonsuicidal self-injury (NSSI) is associated with stigma, and negative attitudes among healthcare professionals toward NSSI have been reported. A person-centered approach that focuses on how individuals with lived experience of NSSI perceive the treatment and care they receive is invaluable in reducing barriers to help-seeking and improving treatment and mental healthcare services. The aim of the current qualitative study was to explore the perceptions of young adults when they look back upon their experiences of psychiatric treatment for NSSI during adolescence.

METHODS

Twenty-six individuals with lived experience of NSSI who were in contact with child and adolescent psychiatry during adolescence were interviewed. The interviews were analyzed using thematic analysis.

RESULTS

Three main themes were developed: Changed perceptions in retrospect, The importance of a collaborative conceptualization and Lasting impression of the relationship. Participants' perception of themselves as well as the treatment changed over time. The importance of a joint understanding of NSSI and an agreed-upon treatment focus was emphasized. The relationship to the mental health professionals, and experiences of how NSSI was communicated, were salient several years later.

CONCLUSIONS

Healthcare professionals need to communicate about NSSI in a respectful manner and include the perspective of the adolescent with lived experience of NSSI in a joint conceptualization of NSSI and treatment focus.

Alcohol use and suicide-related outcomes in people with a diagnosis of schizophrenia: a comprehensive systematic review and meta-analysis

Suicide is the leading cause of unnatural death among people with a diagnosis of schizophrenia. Alcohol use is a prevalent comorbid feature of schizophrenia and a modifiable risk factor for suicide. We conducted a prospectively registered (PROSPERO, CRD42022358214) systematic review and meta-analysis to quantify the relationship between alcohol use and suicide-related outcomes in schizophrenia.We searched Medline, Embase, and PsycINFO for cross-sectional, case-control and longitudinal studies using exhaustive terms from database inception to December 2022 inclusive. Computation of odds ratios (ORs) and hazard ratios (HRs) were performed using a random-effects model with DerSimonian-Laird estimation. We also evaluated publication bias, study quality, and performed subgroup analysis and meta-regression. Fifty studies, comprising 65 samples, met eligibility criteria. Overall, alcohol use was associated with suicide (OR 1.38, 95% CI 1.21-1.58; HR = 1.32, 95% CI 1.00-1.74), attempted suicide (OR 1.69, 95% CI 1.45-1.98), and suicidal ideation (OR 1.69, 95% CI 1.22-2.34). While there was no evidence of publication bias, between-sample heterogeneity was moderate in analyses of attempted suicide (I2 = 39.6%, p = 0.01) and suicidal ideation (I2 = 56.0%, p = 0.01). Summary effects were significant in all subgroups except for longitudinal studies of attempted suicide (OR 1.60, 95% CI 0.86-3.00) and studies of suicidal ideation using gender combined samples (OR 1.63, 95% CI 0.99-2.67). Alcohol use is significantly associated with suicide-related outcomes in schizophrenia. Clinicians should routinely inquire about alcohol use in mental health services to focus preventative treatment efforts.

The Relationship between Ambivalence over Emotional Expression and Nonsuicidal Self-Injury Among Chinese Adolescents: A Longitudinal Moderated Mediation Model

BACKGROUND

Nonsuicidal self-injury (NSSI) has become a significant mental health concern for adolescents. Previous empirical studies have shown that ambivalence over emotional expression is positively associated with negative emotions and behaviors. However, little is known about the relationship between ambivalence over emotional expression and NSSI among adolescents. Therefore, this study used a longitudinal design to examine the relationship between ambivalence over emotional expression and NSSI among Chinese adolescents, and also to explore the mediating and moderating mechanisms underlying this relationship.

METHOD

A total of 1,672 students (45.8% males; Mage = 16.12 years, SD = 1.56) in a middle school in Guangzhou were tracked. The investigation was conducted twice, with an interval of 6 months.

RESULTS

Ambivalence over emotional expression was positively correlated with NSSI. After controlling for gender and baseline NSSI, anxiety symptoms fully mediated the association between ambivalence over emotional expression and NSSI. In addition, the relationship between ambivalence over emotional expression and NSSI was moderated by NSSI refusal self-efficacy.

CONCLUSIONS

These findings imply that to decrease ambivalence over emotional expression, to reduce anxiety symptoms, and to promote NSSI refusal self-efficacy may be useful for interventions and preventions of NSSI.HIGHLIGHTSTested the relationship between ambivalence over emotional expression and NSSI in adolescents.Examined a moderated-mediation model over six months.Found the mediated effect of anxiety symptoms and moderated effect of NSSI refusal self-efficacy in the relationship between ambivalence over emotional expression and NSSI.

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.

Covid-19 Lockdown and Non-Suicidal Self-Injury: A Mixed Methods Analysis of NSSI During Australia's National Lockdown

OBJECTIVE

The Covid-19 global pandemic has meant large parts of the world's population have been isolated from others for often months at a time due to lockdown measures to stop the spread. The effects of isolation can be damaging and increase risk of self-injury (NSSI) and suicide. We examined the effects of the first Australian national lockdown on NSSI urges and behavior.

METHOD

We asked 345 people with current or past lived experience of NSSI both quantitative and qualitative questions about how their urges and behavior changed during lockdown and assessed how changes were related to demographic variables including work and living conditions.

RESULTS

Women, socially disadvantaged and unemployed people were at greater risk of increased NSSI urges and behavior. Social connection was important, with both quantitative and qualitative responses indicating that for some, decreased social anxiety and social pressures was related to a reduction in NSSI, whereas for others the lack of social connection and engagement was associated with worsening urges and behaviors.

CONCLUSION

Lockdown had mixed impacts on people with lived experience of NSSI, with most reporting no change or a decrease to urges and behavior, however, for socially disadvantaged people in particular, lockdown lead to worsening urges and behavior and even relapse. Future research might examine these effects longitudinally and with greater focus on intersectionality.HighlightsIdentified NSSI risk/protective factors, and an understanding of lived experienceLockdowns have mixed impacts, some people decreased, some increased NSSISocial connection plays an important role in NSSI engagement and reduction.

Lived experience codesign of self-harm interventions: a scoping review

OBJECTIVES

This study aims to map existing literature describing how people with lived experience of self-harm have engaged in codesigning self-harm interventions, understand barriers and facilitators to this engagement, and how the meaningfulness of codesign has been evaluated.

DESIGN

Scoping review by Joanna Briggs Institute methodology. A protocol was published online (http://dx.doi.org/10.17605/OSF.IO/P52UD).

DATA SOURCES

PubMed, Embase, PsycINFO, Web of Science, Cochrane Library, PROSPERO, ClinicalTrials.gov and relevant websites were searched on 24 December 2022 (repeated 4 November 2023).

ELIGIBILITY CRITERIA

We included studies where individuals with lived experience of self-harm (first-hand or caregiver) have codesigned self-harm interventions.

DATA EXTRACTION AND SYNTHESIS

Results were screened at title and abstract level, then full-text level by two researchers independently. Prespecified data were extracted, charted and sorted into themes.

RESULTS

We included 22 codesigned interventions across mobile health, educational settings, prisons and emergency departments. Involvement varied from designing content to multistage involvement in planning, delivery and dissemination. Included papers described the contribution of 159 female, 39 male and 21 transgender or gender diverse codesigners. Few studies included contributors from a minoritised ethnic or LGBTQIA+ group. Six studies evaluated how meaningfully people with lived experience were engaged in codesign: by documenting the impact of contributions on intervention design or through postdesign reflections. Barriers included difficulties recruiting inclusively, making time for meaningful engagement in stretched services and safeguarding concerns for codesigners. Explicit processes for ensuring safety and well-being, flexible schedules, and adequate funding facilitated codesign.

CONCLUSIONS

To realise the potential of codesign to improve self-harm interventions, people with lived experience must be representative of those who use services. This requires processes that reassure potential contributors and referrers that codesigners will be safeguarded, remunerated, and their contributions used and valued.

Early Risk Factors for Self-Injurious Thoughts and Behaviours: A UK Population-Based Study of 219,581 People

Mental disorders are a major problem among young people. To identify early risk factors of self-injurious thoughts and behaviours (SITB) among young adults with mental health problems, this case-control study drew data from the Clinical Practice Research Datalink (CPRD), a primary care database covering 8% of the UK population. We explored the role of early factors (presenting at 8-14 years old) for suicidal ideation, suicide attempts, and non-suicidal self-injury (NSSI) in young adulthood (age 18-25 years) by performing logistic regressions. Our sample consisted of 219,581 participants, of which 6.51% had at least one SITB in young adulthood. Early risk factors for SITB included early NSSI, suicidal ideation, sexual abuse, behavioural problems, and mood and psychotic symptoms. Frequency of GP visits had a protective effect. Lack of access to mortality data, ethnicity, and socioeconomic status was a limitation of the current study. In conclusion, early symptoms in late childhood/early adolescence can be the start of long-standing problems going into adult life. The training of primary care providers in suicide risk assessment and proper co-ordination with child and adolescent mental health services are crucial for suicide prevention.

Gender and Age Influence on Emergency Department Visits for Non-Suicidal Self-Injuries in School Aged Children in Italy: An 11 Years Retrospective Cross-Sectional Study

Objectives: Non-suicidal self-injury (NSSI) poses a threat in developmental ages, yet there is a scarcity of studies on NSSI trends, especially those in emergency departments (ED). Methods: The aim of this cross-sectional study is to describe trends in ED visits for NSSI among young people aged between 5 and 19 years in Italy from 2011 to 2021 in Piedmont. From the ministerial ED discharge information system, all occurring NSSIs were identified by medical report and/or ICD9CM code and reported as a population rate and a visit rate on all ED requests. Results: The general rate of ED visits remained stable, with around 210,000 (55% males) visits each year, along the whole period from 2011 to 2019, then halved during 2020 and 2021. The NSSI population and visits rates increased from 2013, peaking in 2019 at a rate of around 25 and 23 NSSI visits (girls) and 76 and 69 NSSI (boys) per 100,000 ED visits. In 2020 and 2021, the rate of NSSI visits increased, particularly in girls and among older adolescents. Conclusion: The gradual increase of NSSI over the last decade is a rising public health issue, which deserves wider attention to ensure early detection and prevention.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

DSM-5 non-suicidal self-injury disorder in a community sample: comparing NSSI engagement, recency and severity among emerging adults

Up to one in five emerging adults engage in non-suicidal self-injury (NSSI). Providing a better understanding of factors that differentiate between who engages in lifetime NSSI and who is more likely to engage in recent and clinically severe NSSI can provide meaningful information for prevention and intervention of NSSI. The present study (n = 669) considered NSSI lifetime engagement (no prior history of NSSI vs. lifetime NSSI), recency [past NSSI (>12 months ago) vs. recent (≤12-month) NSSI], and clinical severity among those with recent NSSI (subthreshold vs. DSM-5 NSSI disorder). The prevalence of NSSI disorder was 8.4% in emerging adults aged 18 to 26 years old. Higher anxiety levels were related to NSSI engagement, but only depressive symptoms and NSSI versatility were consistently associated with more recent NSSI and NSSI disorder. A stepped-care approach may be required in addressing NSSI among emerging adults.

Comparing self-harming intentions underlying eating disordered behaviors and nonsuicidal self-injury: Replication and extension in adolescents

OBJECTIVE

Eating disorder (ED) behaviors are often characterized as indirect forms of self-harm. However, recent research has found less clear demarcations between direct self-harming behaviors (e.g., nonsuicidal self-injury [NSSI], suicidal behaviors) than previously assumed. The aim of this study was to replicate findings of this prior research on adult populations in adolescents with a history of restrictive eating.

METHOD

A total of 117 adolescents between ages 12-14 were included in the study. Participants reported the presence and frequency of binge eating, compensatory, restrictive eating, and NSSI. Participants also reported thoughts of and intentions to hurt and kill themselves when engaging in each behavior on average. The t-tests and linear effects models were conducted to compare self-harming thoughts and intentions across behaviors.

RESULTS

Participants reported at least some intent to hurt themselves physically in the moment and in the long-term when engaging in all ED behaviors and NSSI, and reported engaging in these behaviors while thinking about suicide. Direct self-harming knowledge and intentions were most frequently reported with NSSI and longer-term knowledge and intentions via NSSI and restrictive eating. Additionally, participants reported some suicidal thoughts and intentions across behaviors.

DISCUSSION

This study replicates prior research, suggesting that adolescents engage in ED behaviors and NSSI with non-zero self-harming and suicidal thoughts and intentions. ED behaviors and NSSI may better be explained on a continuum. Implications include the recommendation of safety planning during ED treatment.

PUBLIC SIGNIFICANCE STATEMENT

This study highlights the overlap between eating disorder (ED) behaviors, nonsuicidal self-injury (NSSI), and suicide. Though clear distinctions typically exist for motives of self-harming behavior between ED behaviors (i.e., indirect, in the long run) and NSSI (i.e., direct, in the moment), this research suggests that intentions for self-harming and suicide may exist on a continuum. Clinical ED treatment should consider safety planning as part of routine interventions.

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.

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.

Examining the relationship between non-suicidal self-injury and mental health among female Arab minority students: the role of identity conflict and acculturation stress

Background and objective

Research suggests that individuals from minority backgrounds, including immigrants and ethnic minorities, may be at a higher risk for non-suicidal self-injury (NSSI). The aim of the present research is to examine the relationship between non-suicidal self-injury (NSSI) and identity conflict and acculturation stress, depression, and risk behaviors among female Arab minority students.

Methods

The sample analyzed consisted of 1,529 female Arab students (85.8% B.A. students, 14% M.A. students) aged 21-54 (M = 23, SD = 4.17). The participants completed self-reported questionnaires assessing NSSI engagement, identity conflict and acculturation stress, depression, and risky substance use behavior.

Results

As expected, we found a significant positive association between NSSI and identity crisis. In addition, an identity conflict and acculturation stress impact the effect of depression and risky substance use behaviors in engaging in self-injury. Namely, participants were more likely to engage in NSSI when they also experienced identity conflict and acculturation stress and exhibited depressive symptoms and tended to display risky substance use behavior.

Conclusion

These findings provide evidence that the relationship between depression, risky substance use behavior, and NSSI may be stronger among individuals who experience higher levels of identity conflict and acculturation stress. Implications for intervention and future research are briefly presented.

How are parental practices and attitudes towards corporal punishment related to child academic, developmental, or psychological-emotional dysfunctioning?

Corporal punishment (CP) is a widely spread disciplining practice among parents and caregivers globally. Our paper aimed to explore the relationship between the parental attitudes towards CP, expected outcomes of CP, and parenting practices on one hand, with the reported dysfunctions of their children, on the other. Additionally, we aimed to explore the relationship between the use of CP and the reported academic, developmental, and psychological-emotional dysfunctions of their children. The present study involved a nationally representative sample of 1186 parents in Serbia, who had at least one child aged 0-18 years at the moment of interviewing. The parents filled out a series of questionnaires on their attitudes towards CP, expectations of CP outcomes, and their parental practices. Findings indicate that parents that report having a child with dysfunctions have positive attitudes towards CP and expect positive outcomes of CP. These parents also report using more CP as a disciplining method, as well as other harsh disciplining practices. We also identified parental positive expectations of CP, use of physical assault, psychological aggression, neglect as significant predictors of reported child dysfunctions severity. Having all the results in mind, we can assume that children with health-related and school-related issues might be at potential risk of further maltreatment.

The Association between Nonsuicidal Self-Injury and Perfectionism in Adolescence: The Role of Mental Disorders

Previous evidence has drawn attention to the fact that maladaptive perfectionism is a risk factor for engagement in nonsuicidal self-injury (NSSI). Until now, few studies have examined this topic, especially among community adolescents. The aim of this study was to explore the relationship between perfectionism dimensions and NSSI functions to examine the potential mediating effect of mental disorders. Altogether, 146 Hungarian community adolescents (ages 13-18 years) were involved. All participants completed the Hungarian adaptation of the Inventory of Statements about Self-Injury (ISAS), the Frost Multidimensional Perfectionism Scale (FMPS), and the Mini International Neuropsychiatric Interview Kid. To analyse the interrelationships among NSSI, perfectionism, and mental disorders, we conducted regression and network analysis. Of the 146 adolescents, 90 (61.64%, girls: 71.11%) engaged in NSSI. The Concern over Mistakes and Doubts about Action scales of the FMPS significantly and positively predicted both NSSI intrapersonal and interpersonal motivation, with comparable effect sizes, and this association was fully mediated by anxiety disorders. There was a significant direct negative relationship between the FMPS Organisation dimension and both main NSSI functions. This study draws attention to an increasing trend and the extremely high NSSI prevalence rate among community adolescents. Adolescents with perfectionistic concerns are at heightened risk for anxiety disorders, which can increase their vulnerability to NSSI engagement.

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 Effectiveness of a Mindfulness Induction as a Buffer Against Stress Among University Students With and Without a History of Self-Injury

Stressful experiences are abundant in university and students with a history of nonsuicidal self-injury (NSSI) may be hyper-reactive to stress. While brief mindfulness inductions have been proposed as a buffer against acute stress, whether they function differently in students with a history of NSSI remains in question. This study sought to explore the impact of an online mindfulness induction on (a) two facets of state mindfulness (i.e., mind and body) and (b) state stress, following a stress induction task, in university students with versus without a history of NSSI. Participants were Canadian university students with (n = 82; Mage = 21.30 years, SD = 2.92; 87.8% female) and without (n = 82; Mage = 21.71 years, SD = 3.18; 87.8% female) a history of NSSI, matched on gender, age, and faculty, who completed baseline (T1) measures of state stress and state mindfulness. Participants were randomly assigned to complete a mindfulness induction or an active control task. All participants then underwent a stress induction, and again completed measures of state stress and state mindfulness (T2). Results from three-way mixed ANOVAs revealed that state stress increased from T1 to T2 for all participants, regardless of group or condition. Among those assigned to the control condition, state mindfulness of the body was lower at T2 for participants with a history of NSSI compared to those without such a history. However, participants with a history of NSSI who completed the mindfulness induction reported greater state mindfulness of the body at T2 than students with a history of NSSI who completed an active control task. Findings highlight the unique response of university students with a history of NSSI to a brief mindfulness induction. Implications are discussed in the context of future research and clinical applications.

Executive functions in non-suicidal self-injury comorbid first-episode and drug-naïve depression among adolescents

Executive functions(EFs) may be associated with the emergence of non-suicidal self-injury(NSSI) due to their role as behavior controllers. EFs includes three core cognitive processes: inhibitory control, working memory, and cognitive flexibility(i.e. the ability to selectively alter cognitive strategies to generate appropriate behavior in the changing environment). This study aimed to systematically explore the three core EFs in depressed adolescents with NSSI. The data was obtained from the baseline data of the Chinese adolescent depression Cohort. The adolescents underwent cognitive assessments to yield domain-specific scores in EFs using the Digit Span Backward test(DSB), the Stroop Color-word interference test- color-word condition(Stroop-CW), and the Wisconsin Card Sorting tests(WCST). The significant differences in WCST scores were found between the NSSI group and the non-NSSI group. NSSI frequency was moderately positively correlated with total errors and negatively correlated with the number of categories completed. The number of categories completed in the "≥200″ NSSI frequency group was significantly lower than that in the "≤10″ NSSI group. The current findings suggested that depressed adolescents who had engaged in NSSI have poorer cognitive flexibility performance compared to adolescents without NSSI. As the frequency of NSSI increased, cognitive flexibility might become worse. These results provide evidence of a connection between executive dysfunctions and NSSI in depressed adolescents.

A qualitative study on lived experience of self-harm in South Asians in the UK: From reasons to recovery

OBJECTIVES

Self-harm rates and clinical presentations differ by ethnicity. South Asian women are at risk of self-harm. Previous research suggested investigating individuals' experiences with self-harm with qualitative studies in developing self-harm prevention strategies. This research aims to explore self-harm experiences among South Asians in the United Kingdom.

DESIGN

Qualitative study.

METHODS

Participants were recruited via third-sector organizations and online platforms. Semi-structured interviews were conducted with 11 South Asian individuals with a history of self-harm living in the United Kingdom. The data were analysed based on a reflective thematic analysis approach.

RESULTS

Results revealed four main themes: (1) reasons for self-harm; (2) recovery journey; (3) culture and mental health; and (4) the transition to suicidal thoughts and behaviours. Reasons for self-harm included negative life circumstances, social life difficulties, challenges faced during COVID-19 and mental health problems. Participants described their recovery journey by acknowledging the role of professional help, self-care, psychoeducation and personal growth, improving social relationships, and faith and spirituality. Cultural factors included generational differences and stigma. Culturally adapted psychological interventions were perceived as promising. The reported transition from self-harm to suicidal behaviours was linked to experiencing major stressful life events and the use of severe methods of self-harm.

CONCLUSIONS

The findings suggest that socio-cultural factors impact mental health and recovery processes among South Asians. Mental health services should consider improving culturally sensitive clinical practices in responding to self-harm among South Asian communities.

Autonomic dysregulation and self-injurious thoughts and behaviours in children and young people: A systematic review and meta-analysis

Background

Self-injurious thoughts and behaviours (SITBs) have been associated with dysfunction of the Autonomic Nervous System (ANS) in children and young people, suggesting that objective ANS measures may aid assessment of suicide risk, but a systematic synthesis of this literature is currently lacking.

Methods

Following a pre-registered protocol (PROSPERO CRD42022327605), we conducted a systematic search of PubMed, Medline, Embase, PsycINFO, and Web of Science, for empirical studies published until 10th May 2022 that compared indices of ANS functioning in individuals aged 0-25 years with versus without SITBs, or reported continuous associations between ANS measures and SITBs. Study quality was assessed with the Newcastle-Ottawa Scales. Pooled effect sizes (Hedge's g) were estimated with random-effects meta-analytic models.

Results

Twenty studies (1979 participants) were included in our systematic review, with 16 included in meta-analyses. Results suggested that SITBs were associated with altered cardiac indices of arousal (g = -0.328, p < 0.001), which was driven by lower heart rate variability in individuals with SITBs (g = -0.375, p = 0.025). Overall results for electrodermal activity were not significant (g = 0.026, p = 0.857), but subgroup analyses showed increased activity in studies of individuals who engaged specifically in non-suicidal self-harm (g = 0.249, p = 0.014) but decreased activity in the remaining studies (g = -0.567, p = 0.004).

Conclusions

Our systematic review and meta-analysis found evidence of reduced parasympathetic regulation as well as more tentative evidence of altered electrodermal activity in children and young people displaying SITBs. Future longitudinal studies should test the clinical utility of these markers for detecting and monitoring suicide risk.

Non-suicidal self-injury in Chinese population: a scoping review of prevalence, method, risk factors and preventive interventions

Non-suicidal self-injury behavior (NSSI) is a serious public health concern that requires immediate attention. Despite the high prevalence of NSSI among the Chinese population, there is a significant gap in research on the comprehensive picture of this field. Therefore, a scoping review was conducted to investigate the prevalence, methods, risk factors, and preventive intervention programs related to NSSI in China. The review found that the estimated lifetime prevalence of NSSI among Chinese youth population is alarmingly high at 24.7% (N = 1,088,433). Common methods of NSSI include scratching, hitting, and biting. Additionally, the review synthesized 249 risk factors based on the biopsychosocial-ecological framework, highlighting the urgent need for intervention. However, only 12 empirical studies focus on NSSI prevention or intervention programs were included. These findings underscore the necessity for more clinical practices and larger studies to identify effective interventions and ultimately alleviate the burden of NSSI on the Chinese population.

Impact of the COVID-19 and psychological risk factors on non-suicidal self-injury behavior among high school students: a one-year follow-up study

OBJECTIVES

Non-suicidal self-injury (NSSI) behavior is a severe public health issue in adolescents. This study investigated the possible impact of the coronavirus disease 2019 (COVID-19) and analyzed psychological risk factors on adolescent NSSI.

METHODS

A one-year follow-up study was conducted in September 2019 (Time 1) and September 2020 (Time 2) among 3588 high school students. The completed follow-up participants (N = 2527) were classified into no NSSI (negative at both time points), emerging NSSI (negative at Time 1 but positive at Time 2), and sustained NSSI (positive at both time points) subgroups according to their NSSI behaviors before and during the COVID-19 pandemic. Perceived family functioning, perceived school climate, negative life events, personality traits (neuroticism, impulsivity, and self-control) were assessed using self-report scales.

RESULTS

The data indicated an increase (10.3%) in the incidence of NSSI. Compared to no NSSI subjects, the emerging NSSI and sustained NSSI subgroups had lower perceived family functioning, higher neuroticism, higher impulse-system but lower self-control scores, and more negative life events. Logistic regressions revealed that after controlling for demographics, neuroticism and impulse-system levels at Time 1 positively predicted emerging NSSI behavior, and similarly, higher neuroticism and impulsivity and lower self-control at Time 1 predicted sustained NSSI behavior.

CONCLUSIONS

These findings highlighted the aggravated impact of the COVID-19 on NSSI, and suggested that individual neuroticism, impulsivity, and self-control traits might be crucial for the development of NSSI behavior among adolescent students.

A systematic review and meta-analysis of factors related to non-suicidal self-injury among Chinese adolescents

BACKGROUND

Over the past several decades the prevalence of adolescent non-suicidal self-injury (NSSI) has been rising steadily. Understanding the factors associated with NSSI is a critical public health concern. The current study aims to explore the critical factors related to NSSI among Chinese adolescents.

METHODS

A systematic literature search was conducted to identify the studies meeting our eligibility criteria (published until June 2022) in PubMed, Web of Science, Science Direct, Springer Link, CNKI, VIP, and Wanfang data. The meta-package of R language was used to perform a meta-analysis to compute the pooled effect (r).

RESULTS

A total of 59 studies were included in this analysis, with a sample size of 192,546. Twenty-four democratic, personal, and social factors were examined in current study. The pooled effect value (r) has revealed that 23 factors are associated with NSSI behaviors among Chinese adolescents. The factor, Internet addiction, has demonstrated the greatest association with NSSI compared to other factors.

CONCLUSION

Consistent with previous studies on adolescent NSSI, findings have demonstrated that a number of demographic, personal, and social factors significantly contribute to NSSI behaviors among Chinese adolescents. Future research on prevention and intervention for adolescent NSSI may benefit from targeting these factors.

Association between life events, anxiety, depression and non-suicidal self-injury behavior in Chinese psychiatric adolescent inpatients: a cross-sectional study

Background

Non-suicidal self-injury (NSSI) is a major public health concern among adolescents. Further research is needed into contributors to this behavior, in particular among adolescents with psychiatric disorders. The aim of the present study was to explore the impact of life events and emotional stress on NSSI among hospitalized psychiatric adolescents.

Methods

In this cross-sectional study, 505 Chinese psychiatric adolescent inpatients 10-19  years old completed questionnaires about sociodemographic characteristics and NSSI as well as the Adolescent Self-Rating Life Events Checklist (ASLEC), the State-Trait Anxiety Inventory Form Y, and the Center for Epidemiological Studies Depression Scale. Chi-square test was used to compare the incidence of NSSI in psychiatric adolescent patients with different sociodemographic. T-test was used to compare the total scores and dimension scores of the ASLEC, STAI-Y, and CES-D between the NSSI group and the non-NSSI group. A binary logistic regression model was built to explore the relationships among sociodemographic characteristics, questionnaire scores and NSSI.

Results

Most psychiatric adolescent inpatients (393, 77.8%) reported NSSI behavior. The higher risk for NSSI was observed among female (odds ratio [OR] 2.665, 95% confidence interval [CI] 1.575-4.510), younger adolescents (10-14 years; OR 2.021, 95% CI 1.258-3.245), with a suicide history (OR 2.479, 95% CI 1.549-3.967), or with depression symptom (OR 3.217, 95% CI 1.572-6.582) and those with higher scores of ASLEC (OR 1.019, 95% CI 1.010-1.029).

Conclusion

Our study in China is one of the first to apply to adolescent inpatients the diagnostic criteria of NSSI in the latest edition of the Diagnostic and Statistical Manual of Mental Disorders. Our analysis suggests that NSSI prevalence is disturbingly high among adolescents with mental illness in China. A better understanding of contributing factors, especially negative life events and negative emotions, may guide interventions that can reduce its prevalence.

Clinical Trajectories in Adolescents with and without a History of Non-Suicidal Self-Injury: The BRIDGES Longitudinal Study

Background

Non-suicidal self-injury (NSSI) is a highly prevalent clinical concern in adolescents and is associated with impaired functioning and suicide risk. The BRIDGES (BRain Imaging Development of Girls' Emotion and Self) study was designed to collect longitudinal clinical and neurobiological data to advance our understanding of NSSI in adolescents. The purpose of this paper is to describe the clinical data collected as part of this study, including psychiatric diagnoses, depression symptoms, episodes of non-suicidal self-injury, suicidal thoughts and behaviors, childhood trauma, and personality domains.

Methods

The baseline sample included 164 adolescents aged 12-16 assigned female at birth (Mean age = 14.97, SD = 1.20) with NSSI histories ranging from none to severe. Participants and their parent/guardian were invited to provide data at three time points spaced approximately one year apart. Descriptive analyses were conducted to provide estimates of rates and trajectories of clinical data.

Results

Of the 164 study participants, 75.61% and 57.93% completed the second and third time points, respectively. Visual inspection of the data suggests an overall trend of decreasing severity of psychopathology over time, and adolescents with a history of NSSI appeared to have higher rates of psychopathology than those without.

Conclusions

This paper describes longitudinal clinical trajectories in adolescents with a range of NSSI histories and presents readers with an overview of the rich, publicly available dataset that we hope will inspire future research to advance the understanding of the neurodevelopmental trajectories associated with NSSI, depression, and suicide risk.
