Abstract

Non-suicidal self-injury (NSSI) is common among adolescents and linked to many maladaptive outcomes. This study aimed to assess the prevalence and correlates of NSSI among a community sample of New Zealand adolescents. A self-report questionnaire was administered to adolescents at time 1 (N = 1162, mean age = 16.35), and approximately five months later (time 2, N = 830, mean age = 16.49). Prevalence and bivariate correlations were assessed at both time points, and cross-lag correlations using matched data (N = 495, mean age = 16.23). Lifetime history of NSSI was 48.7 % (females 49.4 %, males 48 %). Consistent with previous international research, NSSI was associated with higher Alexithymia, depression, anxiety, bullying, impulsivity, substance abuse, abuse history and sexuality concerns and lower mindfulness, resilience and self-esteem. Cross-lag correlations suggested NSSI is directly (perhaps causally) related to psychological vulnerability in various domains (e.g., increased depression and lower self-esteem), while bullying may be more distal to NSSI, rather than a proximal predictor.

Questions on abuse were only included in later versions of the school survey because the topic of NSSI proved controversial among secondary schools, and adding questions on abuse in addition to the sensitive questions on NSSI, bullying, substance abuse, and sexuality may have discouraged participation. Thus, the first three schools surveyed did not have abuse questions included in T1 surveys for their students. Abuse questions were included in later administrations when no negative feedback from students or guidance counsellors was received. Schools were given the explicit option of excluding the abuse questions; only one chose to do so.
