# Parents’ coping with their adolescent’s negative emotions following internet-delivered emotion regulation therapy for adolescents with non-suicidal self-injury disorder: a secondary analysis of a randomised clinical trial

## TL;DR

An online therapy program helps parents better cope with their teenager's negative emotions, which may support treatment for non-suicidal self-injury in adolescents.

## Contribution

This study evaluates an internet-delivered therapy for parents of adolescents with non-suicidal self-injury, showing improvements in parental coping strategies.

## Key findings

- Internet-delivered therapy improved parental minimization and distress responses in managing adolescents' emotions.
- Improvements in parental coping were sustained three months after treatment.
- Parental minimization did not mediate adolescent outcomes like self-injury or emotion regulation difficulties.

## Abstract

Non-suicidal self-injury (NSSI) among adolescents is linked to adverse outcomes for youth and their families. While parental involvement is considered essential in treating adolescent NSSI, the effects on parents remain unclear.

To evaluate if Internet-delivered Emotion Regulation Individual Therapy for Adolescents (IERITA) adjunctive to treatment as usual (TAU) is superior to TAU alone in improving parental coping with adolescents’ negative emotions, the durability of potential effects and whether reductions in parents’ minimising of their adolescent’s emotions mediate adolescent outcomes.

166 adolescents with NSSI disorder (93% female; mean (SD) age=15.0 (1.2) years) and their parents (83% female; mean (SD) age=46.5 (5.1) years) were randomised to IERITA plus TAU (n=84) or TAU-only (n=82). IERITA is a 12-week, therapist-guided emotion regulation behavioural therapy, including both adolescents and parents. In parallel to the adolescent, parents participate in a separate internet-delivered course designed to provide skills for understanding and supporting their adolescent. The outcomes were parental coping measured by the Coping with Children’s Negative Emotions Scale-Adolescent version, including minimisation (primary outcome), distress, punitive and expressive encouragement responses at baseline, post-treatment (primary endpoint) and 3 months post-treatment. Parental minimisation was tested as a mediator of adolescent NSSI absence and emotion regulation difficulties.

There were statistically significant treatment effects on parental minimisation and distress responses at post-treatment and 3 months post-treatment, and punitive responses at 3 months post-treatment, favouring IERITA. Parental minimisation did not mediate adolescent NSSI absence or emotion regulation difficulties.

IERITA shows promise for supporting parents of youth with NSSI. Further studies are needed to understand how parental improvement may impact youth with NSSI.

Online family treatment for NSSI can improve how parents handle their adolescents’ emotions.
