Prevalence and correlates of non-suicidal self-injury among patients with bipolar disorder: A multicenter study across China. J Affect Disord 2024; 367:333-341. [PMID: 39233245 DOI: 10.1016/j.jad.2024.08.231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 08/24/2024] [Accepted: 08/31/2024] [Indexed: 09/06/2024]
Abstract
BACKGROUND Non-suicidal self-injury (NSSI) is increasingly prevalent among patients with bipolar disorder (BD), raising concerns in psychology and mental health. Investigating the incidence and factors associated with NSSI is crucial for developing prevention and intervention strategies. METHODS NSSI behaviors were identified using the Ottawa Self-injury Inventory. The Clinically Useful Depression Outcome Scale supplemented with questions for the DSM-5 specifier of mixed features (CUDOS-M) and the Mini International Neuropsychiatric Interview (Hypo-)Manic Episode with Mixed Features-DSM-5 Module (MINI-M) were used to evaluate clinical symptoms. Non-parametric tests, chi-square tests, point-biserial correlation and logistic regression analyses were employed for the purposes of data analysis. RESULTS The enrolled sample comprised 1044 patients with BD from 20 research centers across China. Out of 1044 individuals, 446 exhibited NSSI behaviors, with 101 of them being adolescents, leading to a prevalence of 78.3 % among adolescent patients. The most common methods for females and males were "cutting" (41.2 %) and "hitting" (34.7 %), respectively. By binary logistic regression analysis, young age, female, bipolar type II disorder, with suicidal ideation and mixed states, depressive symptoms and without family history of mental disorder were correlates of NSSI in patients with BD (P < 0.05). LIMITATIONS As a cross-sectional study, causality between NSSI behaviors and associated factors cannot be established. Reporting and recall biases may occur due to self-rating scales and retrospective reports. CONCLUSION Our study indicates a concerning prevalence of NSSI, particularly among young patients with BD in China. Future research should focus on understanding NSSI behaviors in this population and developing effective interventions.

Friendships and peer relationships and self-harm ideation and behaviour among young people: a systematic review and narrative synthesis. Lancet Psychiatry 2024; 11:633-657. [PMID: 39025094 DOI: 10.1016/s2215-0366(24)00170-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 05/03/2024] [Accepted: 05/20/2024] [Indexed: 07/20/2024]
Abstract
Friendships and peer relationships have an important role in the experience of self-harm ideation and behaviour in young people, yet they typically remain overlooked. This systematic review and narrative synthesis explores the extant literature on this topic to identify important relationships between these constructs. We did a keyword search of peer-reviewed empirical articles relating to friendships and peer relationships and self-harm ideation and behaviour in young people (aged 11-25 years). We identified 90 articles with evidence primarily from adolescents aged 11-18 years, including mixed genders and a majority of White individuals. Findings highlight substantive relationships between the key constructs, showing that: characteristics of friends and peers, including their self-harm ideation and behaviour, relate to and predict ego self-harm ideation and behaviour; friends and peers are important sources of support; and evidence on causal mechanisms is scarce but highlights potential peer selection and influence processes. Studies of the friends and peers of young people with self-harm ideation and behaviour highlight that: friends' attitudes to self-harm and suicide influence their responses to peers with self-harm ideation and behaviour; and friends who are bereaved and friend supporters experience negative outcomes such as symptoms of depression, anxiety, PTSD, and grief, alongside difficult emotions. Despite substantial heterogeneity across samples, study designs, and definition or measurement of the primary constructs, this work presents an initial step in organising a complex literature on a crucially important topic, which can help to inform future research and evidence-based interventions.

BMC Psychol 2023; 11:406. [PMID: 37990280 PMCID: PMC10664551 DOI: 10.1186/s40359-023-01393-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 10/12/2023] [Indexed: 11/23/2023] Open
Abstract
BACKGROUND Internet addiction, defined as uncontrolled behaviour resulting from the use of the Internet without the influence of addictive substances, which can seriously impair academic, occupational and social functioning. Non-suicidal self-injury, defined as self-injurious behaviour without the intent to die, and its addictive characteristics are similar to those of Internet addiction. Currently, there is a lack of research on the relationship between non-suicidal self-injury and Internet addiction. The purpose of this study was to examine the relationship between non-suicidal self-injury and internet addiction among college students and the role of self-concealment in this relationship. METHODS In this study, data were collected online between December 2022 and January 2023 from 600 university students in Chengdu, Sichuan Province, China, using purposive sampling. The questionnaires included the Non-Suicidal Self-Injury Inventory (NSSI), the Self-Concealment Scale (SCS) and the Internet Addiction Test (IAT). RESULTS A total of 573 valid questionnaires were recovered, with a valid recovery rate of 95.50%. CONCLUTION The results suggest that self-concealment plays a partial mediating role between non-suicidal self-injury and internet addiction among college students. The authors emphasized the importance of internet addiction. In order to reduce the occurrence of internet addiction, schools should provide targeted interventions to promote the psychological health of college students' internet addictive behaviours.

Abstract
PURPOSE This study aimed to investigate the attitudes of adolescents toward NSSI, and to explore their perspectives on barriers to seeking professional treatment for NSSI. METHODS A qualitative phenomenological design was used to conduct in-depth interviews with 17 adolescents with NSSI in a psychiatric hospital in Beijing, China. Data from the 17 adolescents were analyzed using Colaizzi's 7-step analysis. RESULTS Two themes were extracted: (1) attitudes toward NSSI (normal, effective, ignorant, disgraceful); (2) subjective/objective barriers to seeking professional treatment (negative attitudes toward NSSI, fear of being regarded as an attention getter, fear of interfering with personal relationships, fear of aggravating the family burden, fear of being criticized by parents, fear of ongoing hospitalization, fear of the side effects of medication, etc.). CONCLUSIONS It is suggested to strengthen the knowledge of NSSI among adolescents, families and society, formulate interventions suitable for Chinese sociocultural backgrounds, and cultivate the specialty literacy of mental health nurses and their abilities to identify the barriers, which are required for eliminating barriers to seeking professional treatment and establishing a system for seeking full coverage of professional treatment.

Abstract
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.

Abstract
BACKGROUND Major depressive disorder (MDD) with non-suicidal self-injury (NSSI)(MDD/NSSI) has been found to differ from simple MDD without NSSI (sMDD). This study analyzes the amplitude of low-frequency fluctuations (ALFF) to explore the NSSI-relevant local neural activity, and uses functional connectivity (FC) analysis to explore the NSSI-relevant circuits corresponding to alterations in local regions in young adult patients with MDD/NSSI. METHODS A total of 54 patients with MDD/NSSI, 68 patients with sMDD, and 66 matched healthy controls (HCs) were recruited. ALFF and seed-based FC analyses were employed. The NSSI-relevant brain alteration and its associations with clinical variables were examined. RESULTS Compared with the sMDD group, the MDD/NSSI group showed higher ALFF in the right lingual gyrus and right middle occipital gyrus; lower ALFF in the right superior frontal gyrus; higher FC values between the right lingual gyrus and left precentral gyrus; and lower FC values between the right middle occipital gyrus and right paracentral gyrus. Within the MDD/NSSI group, ALFF values of the right superior frontal gyrus and right lingual gyrus were positively correlated with the frequency and severity of NSSI. LIMITATIONS The sample size was small, and the potential influence of medicine on brain activity was not excluded. CONCLUSIONS Our preliminary findings indicate that NSSI-relevant ALFF in the right lingual gyrus, right middle occipital gyrus, and right superior frontal gyrus, as well as the alteration FCs in corresponding brain circuits, may play an important role in the neural basis of MDD/NSSI.

Deviant Peer Affiliation and Non-Suicidal Self-Injury among Chinese Adolescents: Depression as a Mediator and Sensation Seeking as a Moderator. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168355. [PMID: 34444105 PMCID: PMC8391377 DOI: 10.3390/ijerph18168355] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 07/26/2021] [Accepted: 08/04/2021] [Indexed: 12/12/2022]
Abstract
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; Mage = 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.

Abstract
INTRODUCTION Numerous life, peer, and school-related factors have been found to be associated with non-suicidal self-injury (NSSI) among adolescents; however, most studies have not explored the possible reciprocal nature of these associations. The aim of the current study was to examine bidirectional and longitudinal associations between NSSI and several life, peer, and school-related factors (i.e., stressful life events, peer relationships, academic achievement, and attitudes towards school). METHOD Community-based adolescents completed questionnaires assessing the variables of interest at three time points; age 12 (T1; 55.09% girls), age 13 (T2; 56.95% girls), and ages 14-15 (T3; 57.41% girls). In total, 529 adolescents provided complete data across all three-time points. RESULTS Analyses showed a bidirectional association between NSSI and both attitudes towards school and stressful life events. Specifically, stressful life events at T2 predicted engagement in NSSI at T3, and NSSI at T2 predicted increased risk of stressful life events at T3. Similarly, having negative attitudes towards school predicted NSSI at T2, which, in turn, predicted negative attitudes towards school at T3. Further, academic achievement at T1 was negatively associated with NSSI at T2. Peer relationships were neither a predictor nor a consequence of NSSI. CONCLUSIONS Our results suggest that NSSI can be both a predictor and a consequence of various life, and school factors. Focus on these factors in prevention and intervention efforts for NSSI among adolescents may be warranted.
