Emotion regulation in young people with complex mental health and substance use issues

This thesis extended the study of emotion regulation (ER) to young people with complex mental health and substance use issues. It found that: 1) patterns of ER characterised by rumination and avoidance were associated with the most severe mental health symptoms; 2) these components of ER are amenable to change when targeted in treatments, and 3) an ER informed treatment is acceptable for young people in a residential drug treatment.
