Developmental pathways of repetitive non-suicidal self-injury: predictors in adolescence and psychological outcomes in young adulthood

BACKGROUND

Much longitudinal research has been carried out on non-suicidal self-injury (NSSI) during the last decades, but there still is a lack of studies of the individual developmental pathways of NSSI from adolescence into young adulthood. The aim of the present study was to investigate individual developmental pathways of repetitive non-suicidal self-injury (repNSSI) from adolescence into young adulthood, including adolescent predictors and psychological outcomes in young adulthood. Three developmental pathways were targeted: stable adolescence-limited repNSSI; repNSSI prolonged into young adulthood; and late-onset repNSSI; with no repNSSI as comparison.

METHODS

Data were taken from a cohort of compulsory school students (N = 1064) in grades 7-8 in a Swedish municipality. The cohort was followed longitudinally, and this study included all individuals (n = 475) with NSSI data from three waves: T1 (when they were 13-15 years old); T2 (one year later); and T3 (ten years later). RepNSSI was operationalized as self-reports of at least 5 instances of NSSI during the past six/twelve months.

RESULTS

The two pathways that involved stable repNSSI were observed significantly more often than expected by chance, with the strongest overrepresentation for the Prolonged RepNSSI pathway. Still, most adolescents who engaged in stable repNSSI stopped this before reaching young adulthood. Those who stopped did not, however, show a significantly better psychological adjustment in young adulthood than those who continued. Compared to participants with no repNSSI, participants who had stopped still reported significantly more stress, anxiety, and emotional dysregulation. As to the prediction of late onset NSSI, the findings were less robust, but sporadic NSSI at T1 and poor sleep at T2 were significant predictors, whereas depressive symptoms fell just short of significance at both timepoints.

CONCLUSIONS

The present results indicate that among adolescents who engage in stable adolescent repNSSI (1) significantly more individuals than expected by chance still engage in repNSSI ten years later, and (2) those who stop engaging in repNSSI do not show significantly better psychological adjustment than those who still engage in it. The present findings also indicate that late onset of repNSSI as reported in young adulthood to some extent is predictable from symptom measures ten years earlier.

I Just Pulled Myself Together and Realised I had to be Responsible: Adolescents' Experiences of Having a Friend Who Self-Harms

Background

Self-harm usually begins during adolescence and adolescents that self-harm most commonly confide in friends, yet to date, there is little research from the friend's perspective.

Objective

This qualitative study explores adolescents' experiences of what it is like to have a friend who self-harms by cutting and what this experience means for friendship, the wider peer group and psychological well-being.

Methods

Semi-structured interviews were conducted face-to-face with a community sample of eight females aged between 13 and 18 years, living in England. Interpretative Phenomenological Analysis was used to analyse the data.

Results

Four superordinate themes emerged: desperately searching for meaning, I will be there at all costs, too hot to handle and identification. Adolescents were concerned about escalations in their friends' behaviours and felt a sense of duty to help, but the majority experienced a dilemma as to whether to disclose to others and all reported some form of distress.

Conclusions

The results highlight the important, yet complex nature of friendship in this context. Friends play a key role in supporting adolescents who self-harm but need greater support managing this role and the effects. Schools/colleges should educate young people about self-harm to increase their knowledge and skills in relation to supporting a friend with this issue. Furthermore, they should promote environments for talking about mental health openly to give young people increased opportunities for help-seeking.

Intrapersonal and Interpersonal Functions as Pathways to Future Self-Harm Repetition and Suicide Attempts

Background: Research has identified functions of non-suicidal self-harm/self-injury (NSSH) but whether functions change over time, from adolescence to early adulthood, or predict the continuation of the behavior prospectively remains unclear. This study aimed to prospectively explore whether intrapersonal and interpersonal NSSH functions in adolescence predict repetition of self-harm (regardless of suicidal intent) and incident suicide attempts in early adulthood.

Methods: Participants were 528 individuals with NSSH at age 16 years from the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based birth cohort in the UK. Descriptive statistics were used to explore changes in functions over time from age 16 to 21, and logistic regression used to examine associations between NSSH functions and repeat self-harm and suicide attempts at age 21, 24, and 25 years.

Findings: The majority of 16-year-olds with NSSH endorsed intrapersonal (e.g., affect regulatory) functions only (73% at 16 years and 64% at 21 years). Just under half of adolescents (42%) and three quarters of 21 years olds reported more than one function simultaneously. A greater number of intrapersonal functions at 16 years independently predicted future repetition of self-harm at ages 21–25 years, over and above interpersonal functions (OR = 1.46, 95% CI 1.06–2.01). Interpersonal functions during adolescence did not predict repeat self-harm or suicide attempts in adulthood.

Discussion: Our findings suggest that intrapersonal but not interpersonal NSSH functions are a prospective risk factor for future self-harm and might also predict incident suicide attempts. The results highlight the central role of underlying affective difficulties and motivations in self-harm maintenance.
