Non-Suicidal Self-Injury Among Incarcerated Adolescents: Prevalence, Personality, and Psychiatric Comorbidity

Impact of mentalization, identity diffusion and psychopathology on nonsuicidal self-injury among adolescents

INTRODUCTION

Nonsuicidal self-injury (NSSI) has become a major public health issue in adolescents. This cross-sectional case-controlled study aims to assess the impact of identity diffusion, psychopathology, and mentalization on NSSI in adolescence.

METHODS

The study sample consisted of 153 adolescents (76.5% girls; Mage = 15.6 years). The sample included 56 clinical cases of NSSI, 45 psychiatric cases without NSSI, and 52 healthy controls, all recruited in Ankara, Türkiye, from June 1, 2022, to August 31, 2022. Mentalization was assessed by "The Movie for the Assessment of Social Cognition" (MASC) which categorizes mentalizing as "correct mentalizing" "hypermentalizing" "undermentalizing" and "no-mentalizing". All participants filled in the Self-Injurious Behavior Screening Questionnaire, Assessment of Identity Development in Adolescence (AIDA), and Youth Self Report (YSR), and Inventory of Statements About Self-injury (ISAS).

RESULTS

The NSSI group showed lower mentalizing capacity than the healthy control group (p = .011), and more no-mentalizing errors than the other two groups (p = .014). Identity diffusion scores were higher in the NSSI group than in the other two groups (p < .001). Multivariate logistic regression analysis showed that the presence of maternal psychiatric disorder (p = .019, OR = 5.21), identity diffusion (p = .007, OR = 1.02), no mentalizing (p = .049, OR = 1.28), and total psychopathology symptoms (p = .009, OR = 1.12) had a significant impact on NSSI.

CONCLUSIONS

Current findings suggest that transdiagnostic approaches, including mentalization and identity diffusion, may contribute to a more comprehensive understanding of NSSI and to the development of clinical interventions.

Risk and Protective Factors Associated with Self-Cutting Behavior Among Adolescents at First Contact with the Juvenile Court

Adolescents involved in juvenile legal system are at increased risk for self-cutting behavior, however, correlates associated with elevated risk remain underresearched, particularly among youth with first involvement with the court. This study utilized an epidemiological two-year longitudinal study involving 401 adolescents at first contact with the court (Mage = 14.47; SDage = 1.94 years; 43% female; 42% Latinx/Hispanic) and an involved caregiver. Study aims examined key prospective psychosocial correlates of self-cutting behavior. Baseline assessments captured individual and family level risk and protective factors; self-cutting behavior was assessed longitudinally every four months post-baseline for 24 months. Psychosocial correlates of self-cutting behavior included adolescent affect dysregulation, post-traumatic stress disorder symptoms, impulsive decision making, anxiety and depression symptoms. Significant protective factors included positive communication with caregiver and family, higher self-esteem, and having a caring and supportive family. These findings suggest that internalizing symptoms as well as difficulties with emotion regulation and impulsive decision making are correlated with heightened risk for self-cutting behavior among adolescents involved in the juvenile legal system. The findings also suggest that individual and family level protective factors, like positive communication and a supportive family, are associated with decreased risk for self-cutting behavior among adolescents at first contact with the court.

Functions of nonsuicidal self-injurious behavior in Russian patients with suicidal ideation

Introduction

Nonsuicidal self-injurious behavior (NSSI) is an important risk factor for future suicide attempts. Previous research has identified a number of motivations for engaging in NSSI. The aim of the present study was to translate the Inventory of Statements About Self-Injury (ISAS) into Russian and then to evaluate its psychometric properties in a sample of patients with non-psychotic mental disorders and suicidal ideation (SI). Other aims were to determine the prevalence of specific NSSI functions in this population and to assess the relationship between different NSSI functions and clinical and psychological parameters.

Participants and methods

The study was conducted at the largest center for non-psychotic mental disorders in Moscow. All admitted patients with both NSSI and SI completed the Russian version of the ISAS-II, underwent the Self-Injurious Thoughts and Behaviors Interview, and completed the Personality Inventory for DSM-5 and ICD-11 Brief Form Plus-Modified, the Beck Depression Inventory, and the State-Trait Anxiety Inventory.

Results

A total of 614 patients were included in the study. 543 (88.4%) patients were assigned female at birth with a mean age of 24.86 (7.86) years. Factor analysis supported a two-factor structure (Intrapersonal and Interpersonal) of the Russian version of the ISAS-II, but in contrast to the original study, the "Marking distress" function loaded more strongly on the Interpersonal factor. In people with non-psychotic mental disorders and SI, Interpersonal functions of NSSI are associated with more severe depressive symptoms (r = 0.34), 12 months history of NSSI (r = 0.30), higher number of NSSI methods (r = 0.41), likelihood of future NSSI (r = 0.35) and psychoticism (r = 0.32).

Conclusion

The Russian version of the ISAS-II is a valid and reliable instrument for assessing NSSI functions in a population at high risk for suicide attempts. Interpersonal functions are associated with a number of unpleasant clinical and psychological features.

Heterogeneity in Adolescents' Non-Suicidal Self-Injury Behaviour Trajectories Based on the Group-Based Trajectory Model and a Decision Tree Analysis of Family-Related Determinants

Background

Non-suicidal self-injury (NSSI) is a global public health problem. While some studies have noted the importance of behavioural development patterns in NSSI, most NSSI research is based on cross-sectional survey data. Few studies explore the time-series heterogeneity of trajectories of NSSI symptoms and family-related influencing factors of NSSI.

Aim

The purpose of the study was to identify the heterogeneity in trajectories of adolescents' NSSI behaviour and their family-related influencing factors.

Methods

The group-based trajectory model (GBTM) was used to identify the heterogeneity in the NSSI behaviour trajectories of 208 adolescents in China. Next, the decision tree model (DTM) was used to analyse which family related factors influence the trajectory type.

Results

The GBTM revealed two heterogeneous trajectories of NSSI behaviour: the high-risk and low-risk NSSI behaviour groups. Next, DTM's average accuracy was 83.2%. A total of seven independent variables were used for the DTM: gender, number of NSSIs in the past month, and family economic, family structure, family conflict, parental psychological control, parental behavior control and family intimacy risks. Family conflict risk was located at the root node and was the most important factor.

Conclusion

Heterogeneity within the population should be considered in the management of adolescents' NSSI behaviours. Further, from the perspective of family system theory and cumulative risk, focusing on the adverse effect of multiple risk factors on adolescents' NSSI addiction is more meaningful rather than the impact of single risk factors. Studies that use time series data should focus on the trend of dynamic changes in NSSI addiction characteristics over time.

Effects of BPD tendencies and subjective well-being on NSSI in adolescents with PTSD

Background

Severe posttraumatic stress disorder (PTSD) may lead to non-suicidal self-injury (NSSI), and borderline personality disorder (BPD) tendencies may play a role in this process. Secondary vocational students experience more social, familial and other pressures and are more vulnerable to psychological problems. Thus, we explored the effect of BPD tendencies and subjective well-being (SWB) on NSSI in secondary vocational students with PTSD.

Methods

A total of 2,160 Chinese secondary vocational students in Wuhan participated in our cross-sectional investigation. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), criteria for PTSD, NSSI Questionnaire, Personality Diagnostic Questionnaire-4+, subjective well-being scale, and family adaptation, partnership, growth, affection, and resolve (APGAR) Index were used. We conducted a binary logistic regression model and linear regression analysis.

Results

Sex (odds ratio [OR] = 0.354, 95% confidence interval [CI] = 0.171-0.733), BPD tendencies (OR = 1.192, 95% CI = 1.066-1.333) and SWB (OR = 0.652, 95% CI = 0.516-0.824) were independent factors that predicted NSSI in secondary vocational students with PTSD. Spearman's correlation analysis showed that BPD tendencies were positively correlated with NSSI frequency (r = 0.282, P < 0.01). SWB was negatively correlated with NSSI frequency (r = -0.301, P < 0.01). The linear regression showed that BPD tendencies (β = 0.137, P < 0.05 and β = -0.230, P < 0.001) were significantly correlated with NSSI frequency. Spearman's correlation analysis showed that family functioning was positively correlated with SWB (r = 0.486, P < 0.01) and negatively correlated with BPD tendencies (r = -0.296, P < 0.01).

Conclusion

In adolescents, PTSD in response to stressful events could lead to NSSI, and BPD tendencies promote the intensity of NSSI, while SWB diminishes its intensity. Improvement in family functioning may actively guide the development of mental health and improve SWB; such steps may constitute interventions to prevent or treat NSSI.

Multicenter analysis on the non-suicidal self-injury behaviors and related influencing factors-A case study of left-behind children in northeastern Sichuan

BACKGROUND

Few studies have been conducted focusing on the non-suicidal self-injury (NSSI) incidence rate and influencing factors among left-behind children in northeastern Sichuan, China. In this study, we investigated the incidence rate of the NSSI behaviors, levels of anxiety and depression in left-behind children in northeastern Sichuan, and relevant sociodemographic factors.

METHODS

The NSSI behaviors were identified using the Ottawa Self-injury Inventory (Chinese version). Its incidence rate and related influencing factors were evaluated by Cluster sampling; the Depression Anxiety Stress Scale-21 Items (DASS-21) was adopted to assess the levels of anxiety, depression, and stress.

RESULTS

A total of 9450 adolescents met the inclusion criteria, including 543 with NSSI behaviors, and the prevalence of NSSI was 5.7 %. There were 3596 left-behind children, and 243 of them had NSSI behaviors, the NSSI incidence in left-behind children was 6.8 %. There were 5854 non-left-behind children, and the NSSI incidence in non-left-behind children was 5.1 %. Left-behind children's NSSI behaviors were remarkably correlated with five risk factors: being female (OR = 2.411, 95%CI = 1.773-3.279), parents' divorce (OR = 1.742, 95%CI = 1.262-2.404), elder age (OR = 1.120, 95%CI = 1.028-1.219), severe depression (OR = 1.212, 95%CI = 1.148-1.281), and high anxiety (OR = 1.170, 95%CI = 1.093-1.251).

LIMITATIONS

This is a cross-sectional study, we cannot probe into the causality between NSSI behaviors and corresponding risk factors. Reporting and recalling biases may be unavoidable as questionnaires are performed by self-rating scales and retrospective reports.

CONCLUSION

The NSSI behaviors are common in left-behind children in northeastern Sichuan. This study proposes that prevention and intervention measures are necessary for the healthy growth of such children.

Suicide Risk, Self-Injury, and Sleep: An Exploration of the Associations in a Sample of Juvenile Justice Involved Adolescents

Court-involved youth living in the community represent a vulnerable, yet understudied, group that is at risk for a variety of concerning outcomes including increased suicidal ideation, suicide attempts, and non-suicidal self-injury (NSSI). Additionally, sleep disruption, which has been associated with an increase in impulsive decision making, appears to be disproportionately high in this population. However, little is known about any connection between poor sleep and increased suicide risk and NSSI in a group of youth. This study explores the associations between sleep disruption, suicidal ideation, suicide attempts, and NSSI in a sample of court-involved youth in the community referred for mental health evaluation at a court based mental health clinic. Findings suggest that sleep disruption is related to NSSI in this population but not suicidal ideation and suicide attempts. Additional relationships were found between NSSI and being female, as well as having a lifetime history of trauma and marijuana use. Findings suggest that court clinics may wish to screen for sleep disruption as a risk factor for NSSI, and future studies may wish to explore improved sleep as a protective factor for CINI youth.

A retrospective research on non-suicidal self-injurious behaviors among young patients diagnosed with mood disorders

BACKGROUND

Non-suicidal self-injury (NSSI) is an emerging public concern in both clinical and non-clinical settings, especially in the background of the coronavirus disease 2019 (COVID-19) pandemic. Nevertheless, knowledge of NSSI on a certain disease entity in the later stage of the pandemic was scarce.

OBJECTIVE

This study was conducted for the purpose of exploring the current occurrence and characteristics of NSSI in patients diagnosed with mood disorders (MDs) as well as its correlated factors in the later stage of the pandemic.

METHODS

Three hundred and forty-nine eligible subjects (M ± SD, 21.54 ± 7.62) admitted to a mental health center in Wuhan from 11 November 2021 to 31 January 2022 were included in our study. An umbrella questionnaire comprised of demographics, COVID-19-related factors, Yale-Brown Obsessive and Compulsive Scale (Y-BOCS), Pittsburgh Sleep Quality Index-Revised (PSQI-R), Mobile Phone Addiction Index (MPAI), and Ottawa Self-injury Inventory (OSI) was extended to each subject via shared QR code.

RESULTS

Of 349 patients with MDs included, 151 (43.27%) reported NSSI in the recent 1 month, among whom hand, lower arm/wrist, and scalp were the most hurt body parts, and cutting, hitting, and headbanging were the most adopted methods. "Own idea" was the most common origin of NSSI. In the logistic regression model, age bracket, family monthly income, occupation, level of obsessive-compulsive disorder (OCD) symptoms, sleep duration, withdrawal reaction to the mobile phone, and habits of using a mobile phone were independently associated with NSSI.

CONCLUSION

It was revealed by our study that NSSI was quite prevalent among patients with MDs, especially among those students, adolescents, comorbid with OCD symptoms, inadequate sleeping hours, and suffering from withdrawal reaction to mobile phones. Further research on NSSI in various psychiatric disorders and even in non-clinical settings such as the community population was in urgent need since NSSI in China was not rare.
