Risk Factors For Non-suicidal Self-injury Research Articles

Adverse childhood experiences as a risk factor for non-suicidal self-injury and suicide attempts in forensic psychiatric patients

BackgroundExposure to adverse childhood experiences (ACE) have been found to have profound negative consequences on an individuals’ health. Non-suicidal self-injury (NSSI) is a clinically complex and serious global health issue and is closely related to suicide attempts. Previous research has found associations between ACE and NSSI and suicide attempts in clinical samples. However, this association has to our knowledge not been studied to this extent in a sample of forensic psychiatric patients. The aim of this study was therefore to describe the prevalence of adverse childhood experiences (ACE) and their associations with non-suicidal self-injury (NSSI) and/or suicide attempts in forensic psychiatric patients.MethodsThe current study is a cross-sectional study of a consecutive cohort of 98 forensic psychiatric patients (86.7% male) in Sweden. We invited 184 patients with a predicted stay of > 8 weeks who had been cleared for participation by their treating psychiatrist. Of these, 83 declined and 98 eligible patients provided informed consent. Information on ACE, NSSI, and suicide attempts derived from files, self-reports (Childhood Trauma Questionnaire-Short Form; CTQ-SF), and interviews were compared separately among participants with and without NSSI or suicide attempts using t-tests. The dose–response association between ACE and NSSI/suicide attempts was analysed using binary logistic regression.ResultsIn file reviews, 57.2% of participants reported physical abuse, 20% sexual abuse, and 43% repeated bullying by peers during childhood. NSSI and suicide attempts were associated significantly with CTQ-SF total scores, with medium effect sizes (d = .60 to .63, p < .01), and strongly with several CTQ-SF subscales. Parental substance abuse was also associated with NSSI (p = .006, OR = 3.23; 95% confidence interval [CI] = 1.36 to 7.66) and suicide attempts (p = .018, OR = 2.75; 95% CI = 1.18 to 6.42). Each additional ACE factor predicted an increased probability of NSSI (p = .016, OR = 1.29; CI = 1.04 to 1.59) but not of suicide attempts. When anxiety and depressive disorders were included in the model, ACE remained a significant predictor of NSSI.ConclusionsWe report extensive ACE, from both files and self-reports. When comparing groups, correlations were found between ACE and NSSI, and ACE and suicide attempts among forensic psychiatric patients. ACE seem to predict NSSI but not suicide attempts in this group, even when controlling for affective and anxiety disorders. Early ACE among forensic psychiatric patients, especially physical and emotional abuse and parental substance abuse, have important impacts on self-harming behaviours that must be acknowledged both by the institutions that meet them as children and in their later assessment and treatment.

Risk factors and protective factors for nonsuicidal self-injury in adolescents: A hospital- and school-based case-control study.

Nonsuicidal Self-Injury (NSSI) in China has increasingly interested clinicians, although few studies have investigated its risk and protective factors. This study examined the risk factors of NSSI among Chinese adolescents. The researchers recruited adolescent participants with NSSI from a hospital outpatient clinic to form a case group and recruited adolescents without NSSI who provided informed consent from the school to form a control group. Participants completed a questionnaire, and data were analyzed using logistic regression. A total of 138 cases and 276 controls participated in this study. Binary multivariate logistic regression analysis with adjusting for age and sex showed that domestic violence (OR = 8.615, 95%CI: 3.081-24.091), parental overconcern (OR = 6.995, 95%CI: 3.447-14.192), guilt (OR = 4.949, 95%CI: 2.227-10.996), and school bullying (OR = 21.676, 95%CI: 6.799-69.109) increased the risk of NSSI, while peer support (OR = 0.068, 95%CI: 0.030-0.150) and living in an urban environment (OR = 0.157, 95%CI: 0.056-0.437) decreased the risk of NSSI. Some psychosocial factors were confirmed to be independent risk and protective factors for NSSI in this study. However, the clinical significance of the results needs to be interpreted with caution due to sample size limitations.

Sleep problems mediate the influence of childhood emotional maltreatment on adolescent non-suicidal self-injury: The moderating effect of rumination

BackgroundNon-suicidal self-injury (NSSI) is a highly serious public health problem among adolescents in China, and childhood emotional maltreatment has been found to be a risk factor for NSSI. ObjectiveLittle is known about the longitudinal association between childhood emotional maltreatment and NSSI as well as its underlying mediating and moderating mechanisms. Thus, we hypothesized whether sleep problems mediated the association between childhood emotional maltreatment and NSSI, and whether this indirect effect was moderated by rumination. Participants and settingA total of 1987 Chinese adolescents (56.1 % males; ages 10 to 14, M = 12.32, SD = 0.53) completed self-report questionnaires regarding childhood emotional maltreatment, sleep problems, rumination non-suicidal self-injury (NSSI) in three waves. MethodsStructural equation model was used to test a moderated mediation model, with gender, age and socioeconomic status and baseline measures as covariates. ResultsChildhood emotional maltreatment was significantly associated with NSSI, and this association was mediated by sleep problems. Moderated mediation analyses revealed that rumination intensified the relation between childhood emotional maltreatment and sleep problems as well as the relation between sleep problems and NSSI. ConclusionsFindings of this study demonstrate a relationship among childhood emotional maltreatment, sleep problems, rumination and NSSI. Interventions that target sleep problems and rumination may be beneficial for reducing NSSI for at-risk adolescents.

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

BackgroundCybervictimization 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. MethodsUsing three-wave longitudinal data for one year, a total of 1368 Chinese adolescents (60 % boys; Mage at Wave 1 = 15.05 years, SD = 0.85) completed the measurement using a self-report method. ResultsThe 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. LimitationsAll variables in this study were self-reported, and the results should be cautiously generalized to other cultures, according to a sample of Chinese adolescents. ConclusionsResults 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.

Prevalence of Adverse Childhood Experiences and Their Associations with Non-Suicidal Self-Injury Among Chinese Adolescents with Depression.

The presence of adverse childhood experiences (ACEs) in adolescents diagnosed with depression has been associated with an extensive range of mental health issues, including non-suicidal self-injury (NSSI). However, there has been a dearth of research into the prevalence of ACEs and their associations with NSSI among depressed adolescent populations in China. This study aimed to investigate the prevalence of different types of ACEs and their associations with NSSI in depressed Chinese adolescents. Utilizing Chi-squared tests, latent class analysis (LCA), and multinomial logistic regression, the prevalence of different types of ACEs and their associations with NSSI were determined in a sample of 562 adolescents with depression. Among depressed adolescents. 92.9% of depressed adolescents reported ACEs, and the prevalence of emotional neglect, physical abuse, caregiver treated violently, and bullying was relatively high. ACEs, including sexual abuse (OR = 5.645), physical abuse (OR = 3.603), emotional neglect (OR = 3.096), emotional abuse (OR = 2.701), caregiver divorce/family separation (OR = 2.5), caregiver treated violently (OR = 2.221), and caregiver substance abuser (OR = 2.117), were associated with increased odds of exposure among depressed adolescents with NSSI. The high ACEs class (19%), the moderate ACEs class (40%), and the low ACEs class (41%) were identified as latent classes. NSSI was more prevalent in the high/moderate ACEs class compared to the low ACEs class, particularly in the high ACEs class. The situation of the prevalence of ACEs among adolescents with depression was unsatisfactory, and certain types of ACEs were associated with NSSI. Eliminating potential risk factors for NSSI requires the early prevention and targeted intervention of ACEs. Moreover, additional large-scale longitudinal studies are necessary to assess the different development trajectories associated with ACEs, such as the relationships between the different development periods of ACEs and NSSI, and to ensure the adoption of evidence-based prevention and intervention strategies.

Child maltreatment exposure and adolescent nonsuicidal self-injury: the mediating roles of difficulty in emotion regulation and depressive symptoms

BackgroundAlthough child maltreatment (CM) experiences are recognized risk factors for nonsuicidal self-injury (NSSI), the mechanisms underlying this relationship remain unclear. The purpose of this study was to examine whether difficulty in emotion regulation (DER) and depressive symptoms mediate the relationship between child maltreatment experiences and NSSI severity, adjusting for demographic variables.MethodsThe participants were 224 adolescent inpatients recruited from a hospital in China (mean age 15.30 years, SD = 1.83; 78.6% females). Study measures included the Clinician-Rated Severity of Nonsuicidal Self-Injury (CRSNSSI), Childhood Trauma Questionnaire (CTQ-SF), Difficulties in Emotion Regulation Scale (DERS), and Patient Health Questionnaire-9 (PHQ-9). The hypothesized chain mediation model was tested using the structural equation model.ResultsA total of 146 (65.18%) adolescents reported engaging in NSSI during the past 12 months, and 103 (45.98%) participants met the DSM-5 diagnostic criteria for NSSI. Emotional neglect (48.1%) and emotional abuse (46.1%) had the highest prevalence, followed by physical neglect (43.1%) and physical abuse (24.1%), whereas sexual abuse (12.5%) was the least prevalent form of CM. Separately, both DER and depressive symptoms significantly mediated the association between CM and NSSI, with DER being the strongest mediator, with an indirect effect of 49.40% (p = 0.014). At the same time, we also proved a potential chain-mediated pathway of DER and depression in the relationship between CM and NSSI.ConclusionChild maltreatment seems to play a role in the aetiology of NSSI. DER and depressive symptoms both have a mediating role in the relationship between CM and NSSI. Importantly, DER seems to be a mediator with a stronger indirect effect compared to depressive symptoms.

Personality characteristics, defense styles, borderline symptoms, and non-suicidal self-injury in first-episode major depressive disorder.

Non-suicidal self-injury (NSSI) is commonly seen in adolescents with depression and is a high-risk factor leading to suicide. The psychological mechanisms underlying depression with NSSI are still unclear. The purpose of this study was to explore the differences in personality traits, defensive styles, and borderline symptoms among first-episode youth patients with depression and self-injury compared with patients with depression without self-injury and healthy populations. The current study recruited 188 participants, including 64 patients with depression and NSSI, 60 patients with depression without NSSI, and 64 healthy control subjects. Eysenck Personality Questionnaire, the Defense Style Questionnaire, the short version of the Borderline Symptom List, the Beck Depression Inventory, and the Ottawa Self-Injury Inventory were used to assess all participants. Patients with depression and NSSI showed more psychoticism than patients with depression without NSSI and healthy control subjects. Patients with depression and NSSI presented more intermediate defense styles than healthy control subjects. In the patients with depression and NSSI group, the frequency of self-injury in the last week was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. Further regression analysis showed that EPQ-psychoticism and depressive symptoms were independent risk factors for NSSI in patients with depression. This study found that patients with depression and self-injury presented more neuroticism, introversion, EPQ-psychoticism, immature defenses, intermediate defenses, and borderline symptoms. Self-injury frequency was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. EPQ-Psychoticism and depressive symptoms are risk factors for predicting non-suicidal self-injury in patients with depression.

The relationship between negative life events and non-suicidal self-injury (NSSI) among Chinese junior high school students: the mediating role of emotions

BackgroundAdolescent non-suicidal self-injury (NSSI) is common and adolescence is the most common period of first self-injury, and the occurrence of NSSI is influenced by negative life events and emotional symptoms. The mediating role of emotional symptoms in the interaction between negative life events and NSSI has not been carefully investigated yet.MethodsFor middle school students in three schools in a Chinese province, the Adolescents Self-Harm Scale was used to investigate NSSI, the Adolescent Self-Rating Life Events Check List was used to investigate adolescent negative life events, and the Self-Rating Anxiety Scale and Self-Rating Depression Scale were used to assess their emotional symptoms. After the description of general data and the test for differences between groups, the relationship between negative life events, emotional symptoms and NSSI was analyzed using Pearson correlation analysis. Structural equation modeling was used to analyze the mediating role of emotions in negative life events and NSSI.ResultsA total of 2376 junior high school students completed this survey, which revealed an annual NSSI prevalence of 37.1% (n = 881) and a higher prevalence of NSSI among girls and rural adolescents. Among adolescents who developed NSSI, 67.4% (N = 594) used multiple means of self-injury. The most common means of self-injury was hair pulling (51.0%), and the most common NSSI purpose and external factors/events were venting bad emotions or feelings (57.5%) and poor academic performance (44.9%), respectively. Negative life events, emotional symptoms and NSSI were positively associated (P < 0.05). Structural equation modeling with negative life events, emotional symptoms and NSSI as variables showed that the model-fit index matched the data well, with RMSEA = 0.073, AGFI = 0.945, GFI = 0.980, CFI = 0.985, NFI = 0.982, TLI = 0.968, IFI = 0.985, and negative life events, emotional symptoms (anxiety, depression) and NSSI all had direct effects with standardized path coefficients of 0.16, 0.19, and 0.23, respectively, with negative life events playing an indirect role in NSSI through emotional symptoms and emotional symptoms playing an incomplete mediating role in negative life events and NSSI.ConclusionThe prevalence of NSSI was higher among Chinese junior high school students. Both negative life events and emotional symptoms were direct risk factors for NSSI. In addition, negative life events were also indirect risk factors for NSSI, and emotional symptoms played an incomplete mediating role in the relationship between the effects of negative life events and NSSI. This indicates that the combination of reducing the frequency of negative life events while maintaining individual emotional stability during adolescent development can effectively reduce the prevalence of NSSI in adolescents.

Effects of childhood trauma on nonsuicidal self-injury in adolescent patients with bipolar II depression.

This study was performed to explore the effect of childhood trauma on nonsuicidal self-injury (NSSI) in adolescents with bipolar II (BD II) depression. Based on the diagnostic criteria of the DSM-5 and structured interviews to assess the presence or absence of NSSI, 184 adolescent patients with BD II depression were divided into the NSSI (n=112) and non-NSSI (n=72) groups. The Adolescent Nonsuicidal Self-Injury Assessment Questionnaire (ANSAQ), Childhood Trauma Questionnaire-Short Form (CTQ-SF), Toronto Alexithymia Scale (TAS-20), Hamilton Depression Scale (HAMD), and Hamilton Anxiety Scale (HAMA) were used to assess the subjects. The CTQ-SF, HAMD, HAMA, and TAS-20 scores were significantly higher in the NSSI group than in the non-NSSI group (p&lt;.01). Logistic regression analysis showed emotional abuse (p=.028, OR=1.14, 95% CI=1.01-1.28) and age of onset (p=.009) as risk factors for NSSI. Adolescents with onset age 12-13 years (OR=6.30, 95% CI=1.72-23.10) and 14-15 years (OR=2.24, 95% CI=1.04-4.84) had a higher risk of self-injury relative to adolescents aged 16-18 years. Childhood trauma and alexithymia were important influencing factors in adolescent patients with BD II depression. Emotional abuse and age of onset as risk factors for NSSI, and difficulties in emotion recognition were positively associated with the patients' NSSI.

The Relationship between Cyber-Ostracism and Adolescents' Non-Suicidal Self-Injury: Mediating Roles of Depression and Experiential Avoidance.

Based on the experiential avoidance model, the current study aims to test the relationship between cyber-ostracism and adolescents’ non-suicidal self-injury and to explore the mediating roles of depression and experiential avoidance. A sample of 1062 middle school students completed questionnaires on cyber-ostracism, depression, experiential avoidance, and self-injurious behavior. The results showed that cyber-ostracism, depression, experiential avoidance, and non-suicidal self-injury were positively correlated with each other. After controlling for gender and age, the mediation model test shows that cyber-ostracism was significantly and positively associated with non-suicidal self-injury. Depression and experiential avoidance mediated the relationship between cyber-ostracism and non-suicidal self-injury parallelly and sequentially. This study highlights the potential mechanisms of action between cyber-ostracism and adolescent non-suicidal self-injury and finds that cyber-ostracism is a risk factor for non-suicidal self-injury. This founding suggests that extra attention should be paid to the role of the online environment in addition to the offline environment experiences for the intervention of non-suicidal self-injury.

Prevalence of engagement and frequency of non-suicidal self-injury behaviors in adolescence: an investigation of the longitudinal course and the role of temperamental effortful control

Non-suicidal self-injury (NSSI) is among the most frequent maladaptive behaviors reported in adolescence, with prevalence rates around 18–22% in community samples worldwide. The onset of NSSI typically occurs between early and middle adolescence, with a peak during middle adolescence (14–15 years) and a subsequent decline during late adolescence. This study investigated the growth curves of NSSI across four years during adolescence, analyzing simultaneously the probability of engagement in NSSI at least once (i.e., prevalence) and the frequency of engagement once initiated (i.e., severity). Furthermore, the study examined the predicting role of effortful control on NSSI over time (time-varying effects), net of other key risk factors for NSSI, such as anxiety-depression and bullying victimization. A sample of 430 Italian adolescents enrolled in Grade 9 at baseline was involved in the study. Based on the Latent Growth Curve Zero-inflated Poisson methodology, the results indicated a negative quadratic trend of both NSSI prevalence, with an increase between T1 and T3 followed by a decrease in the subsequent wave, and NSSI frequency once initiated, with a peak at T2 followed by a decline over time. The results also showed that adolescents who reported low effortful control abilities had a heightened probability of involvement in NSSI at each time point, whereas no significant association was found with NSSI frequency once initiated. Findings from this study offer important insights into the developmental course of NSSI and point out the need for future in-depth investigations of the mechanisms that might underlie NSSI prevalence and severity throughout adolescence.

Risk factors for nonsuicidal self-injury: A review of the evidence

Risk factors for nonsuicidal self-injury: A review of the evidence

Internalized Homophobia, Body Dissatisfaction, Psychological Distress, and Nonsuicidal Self-Injury Among Young Sexual Minority Men in China.

Purpose: Sexual minority men (SMM) have been shown to be at high risk of nonsuicidal self-injury (NSSI). Internalized homophobia, body dissatisfaction, and psychological distress have been found to be related to NSSI among SMM, but few studies have focused on the mechanisms underlying these associations. Thus, the current study was conducted to examine the association between internalized homophobia and NSSI, and whether body dissatisfaction and psychological distress mediate this relationship among young SMM in China. Methods: In total, 264 young SMM (mean age, 22.00 ± 2.86 years) in Henan Province, China, participated in the study. A set of questionnaires were used to assess participants' internalized homophobia, body fat dissatisfaction, muscularity dissatisfaction, psychological distress, and NSSI. Correlation and mediation analyses were used to examine the data. Results: Internalized homophobia correlated positively with NSSI (r = 0.24, p < 0.001) among young SMM in China. This relationship was partly mediated by body fat dissatisfaction, muscularity dissatisfaction, and psychological distress. Conclusion: The study findings suggest that internalized homophobia is a risk factor for NSSI among young SMM in China, and that body fat and muscle dissatisfaction and psychological distress underlie the association between internalized homophobia and NSSI. In developing interventions targeting NSSI among SMM, the findings of the current study should be considered to improve intervention outcomes.

Association of socioeconomic status with nonsuicidal self-injury and suicidal ideation in young Korean adults.

Although nonsuicidal self-injury (NSSI) in youth is an important mental health concern worldwide, limited studies have investigated its sociodemographic correlates in early adulthood. This study explored associations between socioeconomic status (SES) and self-harm behaviors, including NSSI and suicidal ideation, in a community-based sample of young adults. A total of 414 Korean young adults engaged in NSSI and 200 controls completed online self-report questionnaires assessing sociodemographic and clinical characteristics, using logistic regression to estimate the odds ratio and analyzed risk factors for NSSI, especially the independent influence of SES on NSSI risk. Multivariate regression was performed to identify the role of socioeconomic disadvantage in suicidal ideation in NSSI people. Logistic regression showed that low SES significantly increased NSSI risk. Multivariable regression also revealed that lower SES was related to more severe suicidal ideation in young adults with NSSI after controlling for gender and the higher-severity NSSI index, including the number of NSSI methods used and NSSI intrapersonal functions. This is the first study to directly address socioeconomic gradients of a general population of young adults with NSSI and its effects, and socioeconomic status should be considered preemptively when defining suicide risks of this group and when intervening in self-injurious behaviors.

Nonsuicidal self-injury, psychiatric disorders and pathological internet use among adolescents

IntroductionPrevious studies underline the importance of internalising disorders as risk factors of nonsuicidal self-injury (NSSI), meanwhile only a few research draw the attention to the role of externalising disorders. The possible association between NSSI and pathological internet use (PIU) is also understudied.ObjectivesThe purpose of this study was: 1) to investigate the frequency of NSSI among adolescents with different psychopathology and in different internet user groups of adolescents, 2) to understand the mediator role of psychiatric disorders between NSSI and PIU.MethodsAdolescents were enrolled from a clinical (Vadaskert Child Psychiatric Hospital, Budapest, Hungary) and a school based population (high schools in Budapest, Hungary). The used measurements were: Strengths and Difficulties Questionnaire (SDQ), Deliberate Self-Harm Inventory, Young Diagnostic Questionnaire for Internet Addiction, Mini International Neuropsychiatric Interview Kid.ResultsThere was significant difference in the frequencies of NSSI in SDQ subgroups (U=2127.000; z=-6.170; p &lt;0.001). There was also significant difference in NSSI frequency between normal- and pathological internet users (U=2020.000; z=-2,501; p &lt;0.017 p=0.012). According to the mediator model there was no direct association between PIU and NSSI, however it was mediated by different psychiatric disorders (affective disorders, anxiety disorders, attention deficit/hyperactivity disorder, conduct disorder, opposition defiant disorder, psychoactive substance abuse/dependence, psychotic disorders, suicidal behavior).ConclusionsThe results strengthen that both internalising- and externalising psychopathology are associated with NSSI. Moreover this study underlines the importance of careful screening and treating of comorbid disorders with PIU, which can have a role in the prevention of NSSI and suicide as well.DisclosureNo significant relationships.

Nonsuicidal self-injury and rumination: A meta-analysis.

Trait rumination is the tendency to overthink and focus on negative emotions and events and is related to a number of psychological disorders and maladaptive behaviors including nonsuicidal self-injury (NSSI). The purpose of this study was to conduct a meta-analysis of the relationship between trait rumination and NSSI behaviors. Results from 60 samples showed small effect sizes between trait rumination and NSSI engagement, NSSI frequency, and the number of methods used to self-injure in cross-sectional samples. Results from 13 samples showed small effect sizes between trait rumination and NSSI engagement and NSSI frequency in longitudinal samples. Moderator analyses indicated that this relationship is similar whether the type of rumination is depressive or not and is generally consistent across different ages, genders, and ethnicities. These results help clarify the role of trait rumination as a risk factor for NSSI.

Friend support buffers the relationship between maltreatment and nonsuicidal self-injury in adolescence.

Prior studies have mostly focused on the risk factors for nonsuicidal self-injury (NSSI), but only a few studies have emphasized the related protective factors. The present study examined whether maltreatment and behavioral problems were risk factors for NSSI. Moreover, we also sought to understand whether and how friend support provides a buffer against NSSI. A total of 436 adolescents completed self-report surveys that addressed maltreatment, behavioral problems, friend support, and NSSI at three different time points. There were significant positive correlations between maltreatment and NSSI. In the mediation analyses, we found that maltreatment was indirectly associated with NSSI via behavioral problems. Friend support demonstrated a long-term buffering effect on NSSI. Specifically, friend support had a protective effect on NSSI not only under high maltreatment levels, but also under high behavioral problem levels. These findings contribute to the understanding of the influences of both maltreatment, behavioral problems (risk factors), and friend support (protective factors) on NSSI. In the context of intervention and education, it is important to consider the value of friend support when discussing NSSI.

Nonsuicidal self-injury behaviour in a city of China and its association with family environment, media use and psychopathology

IntroductionIt is not clear whether there are differences in the risk factors for nonsuicidal self-injury (NSSI) between children and early adolescents. Clarifying this question is crucial for identifying actionable prevention strategies for NSSI in these two age groups. MethodThe study, comprising 8611 children and early adolescents (4409 (51.2%) children, 4202 (48.8%) early adolescents), was based on the baseline data of the Chengdu Positive Child Development (CPCD) in China. NSSI behaviours, emotional and behavioural problems and family environment were assessed and obtained via self-reports and parent reports. ResultsOverall, 2520 (29.26%) participants reported having ever engaged in NSSI. There was a higher lifetime NSSI rate in males than in females during childhood, contrasting with higher NSSI rates in females than in males during early adolescence. Furthermore, NSSI shared similar risk factors, including major family conflict and poor relationships with caregivers, in both age groups. Specifically, in children, the risk of NSSI increased along with thought and attention problems (OR, 95% CI: 1.194, 1.106–1.288 and 1.114, 1.028–1.207, respectively), whereas in early adolescents, it increased with anxiety and depressive problems (OR, 95% CI: 1.259, 1.116–1.422). ConclusionsThe findings suggested the need for difference in preventive strategies for NSSI in the two age groups. It may be more efficacious to screen for NSSI in children with thought and attention problems and in early adolescents with anxiety and depressive problems.

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

ABSTRACT 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.

Risk factors for non-suicidal self-injury (NSSI) in adolescents: A meta-analysis

SummaryBackgroundNon-suicidal self-injury (NSSI) in adolescents is a significant mental health problem around the world. Here, we performed a meta-analysis to systematically delineate the risk factors for NSSI.MethodWe searched Medline, Embase, Web of Science and Cochrane for relevant articles and abstracts published prior to 12 November 2021. Pooled odds ratios (ORs) and 95% confident intervals (CIs) were used to assess various risk factors, and publication bias was assessed by Egger's test, the trim and fill method and meta-regression. This study is registered with PROSPERO, CRD42021265885.ResultsA total of 25 articles were eventually included in the analysis. Eighty risk factors were identified and classified into 7 categories: mental disorders (ORs, 1·89; 95% CI, 1·60–2·24), bullying (ORs, 1·98; 95% CI, 1·32–2·95), low health literacy (ORs, 2·20; 95% CI, 1·63–2·96), problem behaviours (ORs, 2·36; 95% CI, 2·00–2·77), adverse childhood experiences (ORs, 2·49; 95% CI, 1·85–3.34), physical symptoms (ORs, 2·85; 95% CI, 1·36–5·97) and the female gender (ORs, 2·89; 95% CI, 2·43–3·43). The range of heterogeneity (I2) was from 20·3% to 99·2%.ConclusionThis meta-analysis found that mental disorders, low health literacy, adverse childhood experiences, bullying, problem behaviours, the female gender and physical symptoms appear to be risk factors for NSSI.
