The effect of acceptance and commitment therapy orientated anger management training on anger ruminations and impulsivity levels in forensic psychiatric patients: A randomized controlled trial.

Purpose: This study aimed at determining the effect of acceptance and commitment therapy (ACT) orientated anger management training on levels of anger rumination and impulsivity in people receiving forensic mental healthcare.

Design And Methods: This was a randomized controlled study. The research data were collected between July 2018 and February 2019. The personal information form, Anger Rumination Scale, and Barratt Impulsiveness Scale were used for data collection.

Findings: Total scores on the Barratt Impulsiveness and Anger Rumination Scales were significantly lower in the experimental group than in the control group (p < 0.001).

Practice Implications: This study adds to existing evidence on the provision of anger management training, offering an evidence-based solution along with necessary knowledge and skills for use by forensic psychiatric nurses.
