High alcohol use a strong and significant risk factor for repetitive self-harm in female and male youth: a prospective cohort study

Predictors of non-suicidal self-injury in adolescents with depressive disorder: the role of alexithymia, childhood trauma, and body investment

Purpose

This study analyzes the relationship of alexithymia, childhood trauma, and body investment to non-suicidal self-injury (NSSI) behaviors in adolescents with depressive disorder and whether they have predictive and diagnostic value for non-suicidal self-injury (NSSI) behaviors in adolescents with depressive disorder.

Patients and methods

A total of 225 patients with a diagnosis of adolescent depressive disorder were included in the study and were divided into two groups according to the DSM-5 criteria: 98 cases without NSSI and 127 cases with NSSI. Compare the demographic data, 24-item Hamilton Depression Scale (HAMD-24), 20-item Toronto Alexithymia Scale (TAS-20), Childhood Trauma Questionnaire-Short Form (CTQ-SF), and Body Investment Scale (BIS) scores between two groups. Binary logistic regression was used to analyze the independent risk factors contributing to NSSI behaviors in adolescents with depression, and establish four predictive models. Based on the models' predictive probability, the ROC curves were plotted to calculate the value of the predictive diagnostic effect.

Results

The group without NSSI had lower scores than the group with NSSI on HAMD-24 total score, TAS-20 total score, difficulty identifying feelings, difficulty describing feelings, and externally focused thinking, as well as lower scores on CTQ-SF total score, physical neglect, emotional neglect, physical abuse, and emotional abuse. In contrast, the BIS total score, body image feelings and attitudes, body care, and body protection factor scores were higher for the group without NSSI. The BIS body care factor score and the CTQ-SF emotional abuse factor score were significantly linked with adolescents diagnosed with depressive disorder who exhibited NSSI behaviors. These results provide a good diagnostic model for adolescents with depressive disorder.

Conclusion

Low levels of body care and childhood emotional abuse may independently contribute to the implementation of NSSI in adolescents with depressive disorder. Body investment and childhood trauma are valuable in diagnosing and predicting NSSI behaviors and should be considered as potentially important factors in clinical treatment.

How are young people's mental health related to their sexual health and substance use? A systematic review of UK literature

OBJECTIVES

The transition from childhood to adulthood is complex and presents challenges to young people's mental health. Mental health impacts and is impacted by a range of contextual and personal factors. Adolescence and young adulthood also coincide with increased experimentation with sex, sexuality and substance use. Addressing the mental health, sexual health and substance-use challenges experienced by young people therefore necessitates an understanding of how these elements relate to one another. By collecting and analysing existing literature, this review aims to identify associations between young people's mental health and sexual health, their mental health and substance use and any resulting gaps-in-knowledge.

CONTENT

Seven electronic databases were searched between March and May 2021 and updated in May 2022 with terms collated under the categories of "young people", "mental health", "sexual health" and "substance use". English-language articles, presenting data from the UK & Ireland, on young people aged 16-24 years inclusive were screened and subjected to a selection process in accordance with PRISMA guidelines (preregistered on PROSPERO, ref. number CRD42021245096). The quality of the resulting articles were assessed using the Mixed Methods Appraisal Tool (MMAT) and findings were tabulated through a data extraction process.

SUMMARY

27 articles were included in the review. Various mental health indices such as depression, anxiety, self-harm, psychotic-like experiences, hypomanic symptoms and binge-purge type eating disorders were found to be associated with higher use of substances such as alcohol, cannabis, ecstasy and generalised drug use. Additionally, mental health indices such as depression, anxiety and self-harm were found to be associated with sex before age 16 and/or unprotected sex at age 16, positive Chlamydia infection and higher levels of sexual activity at a younger age. Overall, cross-sectional associations were stronger than the longitudinal associations presented in the articles.

OUTLOOK

This review into the specific relations between young people's mental health, sexual health and substance use has revealed the complex and bi-directional nature of these associations, with some conditions and substances having been more extensively investigated (e.g., alcohol and depression/anxiety) as opposed to the relations between young people's sexual health and mental health which is lacking in the UK and Irish context. The findings can help inform mental health related policies and service provisions targeted at young people in the UK and Ireland. Areas for future work are suggested.

Predictors of future suicide attempts in individuals with high suicide risk admitted to an acute psychiatry suicide intervention unit in India. A survival analysis study

OBJECTIVE

Determination of suicide vulnerability remains challenging in mental illness. Variability in risk factors identified compound its poor predictability. Longitudinal studies, offering more reliable indices of risk, from developing countries are conspicuously limited. Furthermore, research advances allude to inherent vulnerability. This study, the first of its kind from India, consequently aimed to delineate factors influencing subsequent attempts in mental illness and acute suicidality.

METHOD

Baseline and follow-up information (up to five years) was obtained from medical records of individuals (n = 130) with acute suicidality [recent attempt (first attempt/ reattempt) and high-risk ideators]. Variables were compared between individuals with, and without subsequent suicide attempts. Time to attempt and factors influencing the same was determined using survival analysis, and Cox proportional hazard for estimating the likelihood of a subsequent suicide attempt.

RESULTS

Median duration of follow up of the sample (n = 130) was 23 months. The sample comprised of individuals with a recent attempt (first-time attempt), recent reattempt and recent high-risk ideators. Subsequent suicide attempts were noted in 30 (23.1 %) patients. Baseline sociodemographic and clinical variables, including suicidality, could not differentiate individuals with a subsequent suicide attempt. Survival analysis indicated that 65 % of subsequent attempts occurred within 9 months of discharge. Family history of suicide and the presence of impulsive-aggressive traits were associated with both, reduced survival time and overall increased risk of a subsequent suicide attempt.

CONCLUSION

This study delineates both, the time frame associated with greatest risk, as well as individuals most likely to reattempt suicide. It thereby offers insights into potential windows of opportunity to mitigate prospective suicide risk. Strategies such as enhanced after-care and integrating specific interventions to attenuate impulsive-aggressive behaviors could be a focus to prevent future attempts, thereby decreasing rates of suicide amongst those with mental illness. Furthermore, the findings of this study reaffirm the role of factors that independently confer vulnerability to suicide. Traversing noted regional variations, the findings importantly reinforce the distinct pathophysiological underpinnings of suicide in mental illness.

Predictors of repeated adolescent self-harm: The display of multiple variables and mediators in a 2-year study

BACKGROUND

Data on self-harm (SH) repetition in non-Western adolescents are limited; this study is to survey the predictors.

METHODS

A total of 5879 adolescents (mean age 16.02 years) in Northern Taiwan were recruited. The participants filled in online questionnaires about their sociodemographic data, suicidality, depressive symptoms, self-esteem, social support, family discord, impulsivity, and alcohol and tobacco use at baseline (T1) and at the 1 year follow-up (T2). We used logistic regression analysis to examine the predictors of SH continuation. Generalized structural equation modeling (GSEM) was then estimated to analyze the treatable variables for both years and to investigate their relationships and mediating effects.

RESULTS

A total of 125 students were identified as being in the SH continuation group; while 470 students were identified as being in the SH stop group. The SH continuation rate was 21%; no significant gender difference was found. Logistic regression analysis showed that the predictors of SH continuation were low school ranking, poor quality of listening from relatives, use of the cutting method for SH, and a suicide plan in the past year at T1, and more depressed mood, use of the cutting method for SH, more suicide ideation and plans at T2. Similar predictors were found by GSEM; self-esteem at T1 and depressed mood at T2 were found to be mediators in the pathways.

CONCLUSION

The continuation rate of SH was similar to that reported in Western countries. These predictors should be included in the treatment plan to prevent SH continuation.

Association of Unhealthy Behaviors with Self-Harm in Chinese Adolescents: A Study Using Latent Class Analysis

Previous studies have demonstrated the link between individual unhealthy behaviors and self-harm, but little is known about the influence of multiple unhealthy behaviors on self-harm among adolescents. This study aims to identify the potential patterns of unhealthy behaviors and to examine their associations with self-harm, which may become a useful tool for the screening of self-harm in adolescents. A total of 22,628 middle school students (10,990 males and 11,638 females) in six cities was enrolled in this study by multistage stratified cluster sampling from November 2015 to January 2016. Latent class analysis (LCA) was performed based on five kinds of unhealthy behaviors (unhealthy losing weight (ULW), tobacco use (TU), alcohol use (AU), screen time (ST), and mobile phone dependence (MPD)). Multivariate logistic regressions were used to examine associations between identified subgroups and self-harm. Four subgroups of unhealthy behaviors were identified. Class 1 (71.2%) had the lowest engagement in unhealthy behaviors. Class 2 ((ULW/MPD), 22.3%) had a relatively high prevalence of ULW and MPD. Class 3 ((TU/AU/ST), 3.2%) had a relatively high prevalence of TU, AU, and ST. Class 4 (3.3%) consistently engaged in unhealthy behaviors. Compared to class 1, class 2 (ULW/MPD), class 3 (TU/AU/ST), and class 4 showed OR (95%CI) values of 2.101 (1.964–2.248), 2.153 (1.839–2.520), and 3.979 (3.407–4.645) (p < 0.001 for each), respectively. Class 1, class 2 (ULW/MPD), and class 3 (TU/AU/ST) engagement in unhealthy behaviors was associated with increased self-harm. These findings strongly suggested that self-harm prevention efforts focusing on multiple unhealthy behaviors should be seriously considered for early detection of self-harm.

Risk factors for self-harm repetition in adolescents: A systematic review

Self-harm behavior can begin in early adolescence, with the highest rates of self-harm, between 1990 and 2000 in England, being among adolescents aged 16 to 24 years and there being considerable risk of fatal and non-fatal repetition. Previous systematic reviews have identified risk factors for self-harm in adolescents, but not for the repetition of this behavior. The aim of this review was to synthesise the psychological, psychosocial and sociodemographic risk factors for self-harm repetition in adolescents. By searching four databases, 27 studies were identified and included in the review. Several psychological (e.g., psychiatric morbidity, features of previous self-harm, psychological distress), psychosocial (e.g., alcohol misuse, poor family and peer relationships) and sociodemographic (e.g., age, gender and ethnicity) risk factors were identified for self-harm repetition in adolescents. Several risk factors across all categories for self-harm overlapped with that of self-harm repetition, such as depression, alcohol misuse and female gender. The clinical implications of these findings for practitioners were discussed. As was the case with prior reviews in this area, comparability between studies was limited and a meta-analysis was not possible due to considerable heterogeneity in outcome definitions, measures and methodologies.

Risk Behaviors of High School Students Who Report Knowing Someone Who Self-Harms

Self-harm involves the direct and deliberate destruction of body tissue without suicidal intent and is identified as a maladaptive attempt to cope with stressful emotions. This descriptive, correlational study used a secondary analysis of 5,411 high school students where 72% (n = 3,895) reported knowing someone who had cut or tried to harm themselves in some other way. Students who reported knowing someone who self-harms were more likely to smoke cigarettes, drink alcohol, and use drugs. These students also reported higher rates of bullying, cyberbullying, in addition to Internet risk taking with sexting, and receiving sexts. Nurses, practitioners, and other professionals are in key roles to assess risk taking behaviors in adolescents. Focused health interventions and educational programs that emphasize screening, prevention, risk reduction and safety in addition to long-term impact are imperative to detect vulnerable and at-risk adolescents.

Does State Dissociation Mediate the Relation Between Alcohol Intoxication and Deliberate Self-Harm?

Research supports the notion that alcohol intoxication is a risk factor for deliberate self-harm (DSH). However, the underlying mechanisms for this relationship are poorly understood. We aimed to determine whether alcohol-induced dissociation mediated alcohol's effects on DSH. We used data from a dose-response study of alcohol intoxication and DSH to test the proposed model. Participants were assigned to reach target blood alcohol concentrations (BAC) ranging from 0.00% through 0.10% and then completed a behavioral measure of DSH. Dissociation was assessed using the Alcohol Dissociative Experiences Scale. BAC predicted both dissociation and DSH, but dissociation did not predict DSH. Although research on clinical populations suggests dissociation is related to DSH, our findings suggest dissociation does not mediate the effects of alcohol on self-harm.

Associations between self-harm and distinct types of impulsivity

OBJECTIVE

There is an ongoing debate regarding how self-harm should be classified. The aim of this study was to characterize associations between self-harm and impulsivity.

METHOD

Total 333 adults (mean [SD] age 22.6 (3.6) years, 61% male) were recruited from the general community. History of self-harm was quantified using the Self-Harm Inventory (SHI), which asks about 22 self-harm behaviors. Principal components analysis was used to identify latent dimensions of self-harming behaviors. Relationships between self-harm dimensions and other measures were characterized using ordinary least squares regression.

RESULTS

Principal Components Analysis yielded a three factor solution, corresponding to self-injurious self-harm (e.g. cutting, overdoses, burning), interpersonal related self-harm (e.g. engaging in emotionally or sexually abusive relationships), and reckless self-harm (e.g. losing one's job deliberately, driving recklessly, abusing alcohol). Regression modelling showed that all three dimensions of self-harm were associated with lower quality of life.

CONCLUSIONS

This study suggests the existence of three distinct subtypes or 'latent factors' of self-harm: all three appear clinically important in that they are linked with worse quality of life. Clinicians should screen for impulse control disorders in people with self-harm, especially when it is self-injurious or involves interpersonal harm.
