Acceptance and commitment therapy: a systematic literature review of prevention and intervention programs for mental health difficulties in children and young people

Abstract Background Acceptance and commitment therapy (ACT) is increasingly being used to treat mental health difficulties, however there is a paucity of reviews concerning ACT with children. Aim To examine the literature about ACT interventions for child and adolescent mental well-being. Methods Searches for articles reporting on ACT interventions to prevent/reduce child mental health difficulties were undertaken. Methodological quality was assessed and a narrative synthesis was used to summarize findings about mental health symptoms and psychological flexibility. Results Ten articles were identified focusing on prevention and intervention for anxiety, depression, obsessive compulsive disorder, anorexia nervosa, and trichotillomania. Most studies found that mental health symptoms reduced following an ACT intervention and psychological flexibility increased. However, findings indicate that other active interventions also led to the same changes. Conclusions ACT is a promising intervention for adolescent mental health, although further research is needed to establish whether reductions in mental health symptoms are due to an increase in psychological flexibility
