The management of young people who self-harm by New Zealand Infant, Child and Adolescent Mental Health Services: cutting-edge or cutting corners?

Abstract

Self-harm is common in New Zealand (NZ) young people and can have short-term and long-term consequences, including suicide. This study was undertaken to examine the extent to which evidence-based approaches for addressing self-harm are offered by Infant, Child and Adolescent Mental Health Services (ICAMHS). A national survey of ICAMHS practitioners working with young people who self-harm was undertaken between May and July 2016. Responses from 23 out of 30 ICAMHS confirmed self-harm was a familiar presentation and most commonly associated with diagnoses of depression, anxiety and borderline personality disorder. Cognitive behavioural therapy (47.1%, n = 8), dialectical behaviour therapy (47.1%, n = 8) and acceptance and commitment therapy (5.9%, n = 1) were the treatments of choice, but variably delivered. There were significant training gaps for all types of therapy. Although it is reassuring that many ICAMHS are using evidence-based approaches to address self-harm in young people, there is concerning variability in the way these therapies are delivered. Improvement in training in key modalities, further research into therapist performance and continuous evaluation of workforce development are needed to maximise the effectiveness of proven interventions and provide NZ young people with the state-of-the-art service they deserve.
