Peer Acceptance and Nonsuicidal Self-injury among Chinese Adolescents: A Longitudinal Moderated Mediation Model

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

Objective

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

Method

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

Results

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

Conclusion

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

Reciprocal effect between non-suicidal self-injury and depressive symptoms in adolescence

Background

Non-suicidal self-injury (NSSI) is a common psychological and behavioral problem among adolescents. The COVID-19 pandemic has had a significant impact on people's mental health. To date, few studies have documented the temporal changes in adolescents' psychological status during the pandemic, as well as the impact of large-scale public health intervention strategies. This study contributes to the existing evidence on the subject.

Methods

Participants were 6,023 adolescents aged 10 years and older, with data from two waves of longitudinal surveys, including data for a 7-month interval before and during the pandemic. A cross-lagged model was used to test the bidirectional relationship between NSSI and depressive symptoms in adolescents; logistic regression analysis was used to explore the predictors of NSSI implementation in adolescents with depressive symptoms.

Results

In this study, 32.69% participants reported depressive symptoms at baseline and 34.27% at follow-up; 44.34% participants with depressive symptoms reported NSSI at baseline and 53.44% at follow-up. The duration of the online class, depressed affect, and somatic and related activity were the risk factors for NSSI; sleep duration and positive mood were the protective factors. The lag effect of depression symptoms on NSSI is significant, and so is NSSI on depressive symptoms.

Conclusion

During the COVID-19 pandemic, adolescents' mental health has worsened, resulting in an increase in the prevalence of NSSI among those with depressive symptoms compared to pre-pandemic levels. Early screening for depression is crucial in preventing or decreasing NSSI in adolescents.

Cumulative ecological risk and nonsuicidal self-injury in adolescents: The mediation of depression and the moderation of impulsiveness

BACKGROUND

This study is based on the biosocial model of nonsuicidal self-injury (NSSI), to explore the effects of cumulative ecological risk on adolescents' NSSI, the mediating effect of depression between cumulative ecological risk and adolescents' NSSI, and the moderating role of impulsiveness in this mediating pathway.

METHODS

A total of 16 508 adolescents, with 7903 males (47.9%), participated in the study and completed the Cumulative Ecological Risk Questionnaire, the Short Form of the Center for Epidemiological Studies Depression Scale, the Impulsiveness assessment, and the Nonsuicidal Self-Injury Scale.

RESULTS

(1) There was a significant positive correlation between cumulative ecological risk, depression, impulsiveness, and NSSI; (2) cumulative ecological risk significantly predicted adolescents' NSSI; (3) depression had a mediating effect between cumulative ecological risk and adolescents' NSSI; and (4) impulsiveness moderated both the effects of cumulative ecological risk on adolescents' depression and NSSI and the effects of depression on NSSI in adolescents.

CONCLUSIONS

Impulsiveness and depression are risk factors for adolescent NSSI and play a crucial role between cumulative ecological risk and NSSI in adolescents.

Cybervictimization and non-suicidal self-injury among Chinese adolescents: A longitudinal moderated mediation model

BACKGROUND

Cybervictimization is a risk factor for nonsuicidal self-injury (NSSI). However, there is a lack of evidence on how and under what conditions cybervictimization may influence NSSI. The present study investigated the mediating effect of self-esteem and the moderating effect of peer attachment on the relationship between cybervictimization and NSSI among Chinese adolescents.

METHODS

Using three-wave longitudinal data for one year, a total of 1368 Chinese adolescents (60 % boys; M_age at Wave 1 = 15.05 years, SD = 0.85) completed the measurement using a self-report method.

RESULTS

The longitudinal moderated mediation model revealed that cybervictimization is associated with NSSI via restraining the protective effect of self-esteem. Moreover, high peer attachment could buffer the negative effects of cybervictimization, and protect their self-esteem from being hurt, consequently reducing the likelihood of NSSI.

LIMITATIONS

All variables in this study were self-reported, and the results should be cautiously generalized to other cultures, according to a sample of Chinese adolescents.

CONCLUSIONS

Results highlight the relation between cybervictimization and NSSI. Recommended intervention and prevention strategies include enhancing the self-esteem of adolescents, breaking the cycle of cybervictimization to NSSI, and providing adolescents with more opportunities to build positive friendships with their peers to buffer the negative effects of cybervictimization.

Key factors selection on adolescents with non-suicidal self-injury: A support vector machine based approach

Comparing a family structure to a company, one can often think of parents as leaders and adolescents as employees. Stressful family environments and anxiety levels, depression levels, personality disorders, emotional regulation difficulties, and childhood trauma may all contribute to non-suicidal self-injury (NSSI) behaviors. We presented a support vector machine (SVM) based method for discovering the key factors among mazy candidates that affected NSSI in adolescents. Using SVM as the base learner, and the binary dragonfly algorithm was used to find the feature combination that minimized the objective function, which took into account both the prediction error and the number of selected variables. Unlike univariate model analysis, we used a multivariate model to explore the risk factors, which better revealed the interactions between factors. Our research showed that adolescent education level, anxiety and depression level, borderline and avoidant personality traits, as well as emotional abuse and physical neglect in childhood, were associated with mood disorders in adolescents. Furthermore, gender, adolescent education level, physical abuse in childhood, non-acceptance of emotional responses, as well as paranoid, borderline, and histrionic personality traits, were associated with an increased risk of NSSI. These findings can help us make better use of artificial intelligence technology to extract potential factors leading to NSSI in adolescents from massive data, and provide theoretical support for the prevention and intervention of NSSI in adolescents.

Depressive Symptoms, Perceived Stress, Self-Compassion and Nonsuicidal Self-Injury Among Emerging Adults: An Examination of the Between and Within-Person Associations Over Time

Many emerging adults report experiencing mental health challenges (e.g., depressive symptoms and perceived stress) during the transition to university. These mental health challenges often coincide with increased engagement in nonsuicidal self-injury (NSSI; e.g., self-cutting or burning without lethal intent), but longitudinal research exploring the nature of the associations among depressive symptoms, perceived stress, and NSSI are lacking. In the present study, it was examined whether depressive symptoms and perceived stress predicted increased risk for NSSI over time (or the reverse), and whether these effects were mediated or moderated by self-compassion. The sample consisted of 1,125 university students (Mage = 17.96 years, 74% female), who completed an online survey three times in first year university. A random intercept cross-lagged panel model revealed that higher depressive symptoms, perceived stress, NSSI, and lower self-compassion often co-occurred, but only NSSI predicted increased perceived stress over time. Theoretical and practical implications are discussed.

Stressful life events and non-suicidal self-injury among Chinese adolescents: A moderated mediation model of depression and resilience

Stressful life events are associated with an increased risk of non-suicidal self-injury (NSSI) in adolescence, but the mechanisms explaining this association are unclear. Based on the experiential avoidance model of NSSI, and the protective factor model of resilience, the current study tested depression as a mediator and resilience as a moderator of this association. Chinese adolescents (N = 643; M_age = 15.91; 52.10 % female), anonymously completed self-report measures in classrooms. Results showed that stressful life events was linked to adolescent NSSI in part because of adolescent depression, and resilience was a protective factor that buffered this effect. These findings can inspire practitioners to pay attention to the interaction of risk factors and protective factors when providing prevention and intervention for adolescent NSSI.

The Psychosocial Correlates of Non-suicidal Self-Injury Within a Sample of Adolescents With Mood Disorder

Background

According to the integrated theoretical model, adolescents' behaviors were the outcome of the complex interplay between multiple levels. Non-suicidal self-injury (NSSI) is a serious and high prevalent problem among adolescents with mood disorders. However, a systematic perspective on psychosocial correlates among Chinese clinical adolescents is still rare.

Method

The impact of several factors at the individual (i.e., sex, age, self-esteem, and psychological distress), family (i.e., family structure, family income, and family support), and social level (i.e., living environment, peer support, and teacher support) on the frequency of NSSI behaviors were investigated in the current study. This research included 621 Chinese adolescents with mood disorders from 20 hospitals.

Results

Three-steps hierarchical regression analyses indicated that lower levels of psychological distress and higher levels of self-esteem were most associated with less frequency of NSSI behaviors. In addition, family support was negatively associated with the frequency of NSSI behaviors. After controlling the factors at individual and family levels, no significant association was found between the factors at the social level and the frequency of NSSI behaviors.

Conclusion

These findings provide preliminary support for the notion that adolescent self-esteem and family support may effectively shield them from problematic behavior; nevertheless, adolescents suffering from more emotional pain can be even riskier. Thus, further intervention strategies should consider the non-independence of individual capacities, co-combinatory effects of mood disorder, and family environment in treating those vulnerable Chinese adolescents.

School educational models and child mental health among K-12 students: a scoping review

BACKGROUND

The promotion of mental health among children and adolescents is a public health imperative worldwide, and schools have been proposed as the primary and targeted settings for mental health promotion for students in grades K-12. This review sought to provide a comprehensive understanding of key factors involved in models of school education contributing to student mental health development, interrelationships among these factors and the cross-cultural differences across nations and societies.

METHODS

This scoping review followed the framework of Arksey and O'Malley and holistically reviewed the current evidence on the potential impacts of school-related factors or school-based interventions on student mental health in recent 5 years based on the PubMed, Web of Science, Embase and PsycExtra databases.

RESULTS/FINDINGS

After screening 558 full-texts, this review contained a total of 197 original articles on school education and student mental health. Based on the five key factors (including curriculum, homework and tests, physical activities, interpersonal relationships and after-school activities) identified in student mental development according to thematic analyses, a multi-component school educational model integrating academic, social and physical factors was proposed so as to conceptualize the five school-based dimensions for K-12 students to promote student mental health development.

CONCLUSIONS

The lessons learned from previous studies indicate that developing multi-component school strategies to promote student mental health remains a major challenge. This review may help establish appropriate school educational models and call for a greater emphasis on advancement of student mental health in the K-12 school context among different nations or societies.

Deviant Peer Affiliation and Non-Suicidal Self-Injury among Chinese Adolescents: Depression as a Mediator and Sensation Seeking as a Moderator

Non-suicidal self-injury (NSSI) is an emerging health problem among adolescents. Although previous studies have shown that deviant peer affiliation is an important risk factor for this behavior, the reasons for this relationship are unclear. Based on the integrated theoretical model of the development and maintenance of NSSI and the social development model of delinquency prevention, this study tested whether depression mediated the relationship between deviant peer affiliation and NSSI and whether this mediating effect was moderated by sensation seeking. A sample of 854 Chinese adolescents (31.50% male; M_age = 16.35; SD = 1.15) anonymously completed questionnaires on the study variables. Results of regression-based analyses showed that depression mediated the association between deviant peer affiliation and NSSI, and this effect was stronger among adolescents who reported high sensation seeking. The results demonstrate the role of individual differences in the link between affiliation with deviant peers and NSSI, and have implications for preventing and treating this risky behavior.

Nonsuicidal self-injury in undergraduate students with major depressive disorder: The role of psychosocial factors

BACKGROUND

Nonsuicidal self-injury (NSSI) is related to childhood abuse, family relationships, interpersonal relationships, personality, but the interaction between them is still unclear, and how they interact in major depressive disorder (MDD).

METHODS

Collected data from 444 undergraduate degree students with MDD participated. Used the Eysenck Personality Questionnaire, Childhood Trauma Questionnaire, Interpersonal Relationship Comprehensive Diagnostic Scale, and Family Assessment Device to assess the patients' psychosocial factors. NSSI behavior was assessed through interviews. Use the Chi-square test, Wilcoxon rank-sum test, Kruskal-Wallis H-test, Distance Correlation, Structural Equation Mode for data analysis.

RESULTS

Overall, 34.2% of patients with MDD had a history of NSSI. MDD patients with a history of NSSI had significant differences in psychoticism, neuroticism, emotional abuse, physical abuse, sexual abuse, emotional neglect, troubles in conversation, ability to make friends and family roles. Among these factors, psychoticism was most related to NSSI, and child abuse, interpersonal relationships and family roles played a variety of roles in mediating the relationship with NSSI.

CONCLUSIONS

Psychosocial factors affect the occurrence of NSSI through chain intermediary effects.

Association of Self-Compassion With Suicidal Thoughts and Behaviors and Non-suicidal Self Injury: A Meta-Analysis

Objectives: Self-compassion functions as a psychological buffer in the face of negative life experiences. Considering that suicidal thoughts and behaviors (STBs) and non-suicidal self-injury (NSSI) are often accompanied by intense negative feelings about the self (e.g., self-loathing, self-isolation), self-compassion may have the potential to alleviate these negative attitudes and feelings toward oneself. This meta-analysis investigated the associations of self-compassion with STBs and NSSI. Methods: A literature search finalized in August 2020 identified 18 eligible studies (13 STB effect sizes and seven NSSI effect sizes), including 8,058 participants. Two studies were longitudinal studies, and the remainder were cross-sectional studies. A random-effects meta-analysis was conducted using CMA 3.0. Subgroup analyses, meta-regression, and publication bias analyses were conducted to probe potential sources of heterogeneity. Results: With regard to STBs, a moderate effect size was found for self-compassion (r = -0.34, k = 13). Positively worded subscales exhibited statistically significant effect sizes: self-kindness (r = -0.21, k = 4), common humanity (r = -0.20, k = 4), and mindfulness (r = -0.15, k = 4). For NSSI, a small effect size was found for self-compassion (r = -0.29, k = 7). There was a large heterogeneity (I 2 = 80.92% for STBs, I 2 = 86.25% for NSSI), and publication bias was minimal. Subgroup analysis results showed that sample characteristic was a moderator, such that a larger effect size was witnessed in clinical patients than sexually/racially marginalized individuals, college students, and healthy-functioning community adolescents. Conclusions: Self-compassion was negatively associated with STBs and NSSI, and the effect size of self-compassion was larger for STBs than NSSI. More evidence is necessary to gauge a clinically significant protective role that self-compassion may play by soliciting results from future longitudinal studies or intervention studies.

Bullying Experiences and Nonsuicidal Self-injury among Chinese Adolescents: A Longitudinal Moderated Mediation Model

Bullying experiences play an important role in non-suicidal self-injury (NSSI). However, little is known about how and in what conditions different bullying experiences (i.e., experiences of being pure bullies, pure victims, and bully-victims) may influence NSSI. Guided by the transactional model of development and the integrated model of NSSI, the current study investigated two potential mediators (i.e., peer acceptance and depressive symptoms) and one potential moderator (i.e., psychological resilience) of the relations between different bullying experiences and NSSI. Participants were 812 Chinese adolescents (43% female; Mage at Wave 1 = 13.15 years) from a two-wave longitudinal study with data spanning 1 year. The results show that all three types of bullying experiences can relate to a higher likelihood of NSSI through two indirect pathways: (a) lower peer acceptance to more depressive symptoms, or (b) more depressive symptoms. These indirect effects were weaker for adolescents with higher (versus lower) levels of psychological resilience. Moreover, when bully-victims were distinguished from pure bullies and pure victims and the unique effects for all three groups were tested, the direct and indirect effects were most evident among bully-victims. These findings imply that it is necessary to distinguish bully-victims from pure bullies and pure victims. The results indicate that NSSI may be effectively reduced if interventions focus on promoting peer acceptance and reducing adolescent depressive symptoms, particularly for bully-victims with lower levels of psychological resilience.

Psychometric Properties of the Inventory of Statements About Self-Injury (ISAS) in Iranian Opioid and Alcohol Abusers

Background: Non-suicidal self-injury (NSSI) is one of the most dangerous behaviors linked to substance abuse. The Inventory of Statements About Self-Injury (ISAS) has been developed to better understanding the factors associated with the onset and maintenance of NSSI behaviors. Objectives: The ISAS was translated into the Persian language to study its psychometric properties in Iranian population of opioid and alcohol abusers. Methods: This is a psychometric study investigating opioid and alcohol abusers in Iran, including those residing in addiction rehabilitation camps, prisons, hospitals, and addiction treatment clinics dispensing methadone in 2017. The sample size of this study was 470. The subjects completed the Inventory of Statements About Self-Injury, Barrat Impulsiveness Scale (BIS), and the Distress Tolerance Scale (DTS). Results: The test-retest results were estimated for two weeks using the Intra-class Correlation Coefficient (ICC). The absolute reliability was determined to be 2.62%. There was a significant correlation between convergent and divergent instruments. The results of the exploratory factor analysis on 235 individuals in the sample showed all subscales of the inventory measure a single factor in the Iranian population. The total Cronbach’s alpha coefficient for this subscale was 0.93. Also, the results of confirmatory factor analyses on the rest of the sample (235), after applying the AMOS software suggestions to improve the model, showed this inventory was a good indicator for this population (χ2 = 131.69; P < 0.001; df = 56; χ2/df = 2.35; CFI = 0.97; RMSEA = 0.76; GFI = 0.92). Conclusions: The Persian version of the Inventory of Statements About Self-Injury has high validity and reliability among the opioid and alcohol-abusing population in Iran.
