Investigating the efficacy of a Dialectical behaviour therapy-based universal intervention on adolescent social and emotional well-being outcomes

Online ahead of print.ABSTRACTThere is increasing research interest as to whether Dialectical Behaviour Therapy (DBT), specifically the group skills training component, is an effective early intervention approach when delivered universally in schools. The current study aimed to provide the first large-scale examination of a universal DBT-based intervention and to also determine the extent to which home practice of DBT skills predicted changes in social and emotional outcomes over time. A non-randomised controlled trial design was employed whereby 1071 participants (51.30% Male; M age = 13.48 years) completed either an adapted eight-session DBT skills-training intervention ('WISE Teens) (n = 563) or class-as-per-usual (n = 508). On average, the 'WISE Teens' intervention did not improve outcomes with significant deteriorations or null effects observed across outcomes relative to class-as-per-usual immediately post-intervention. The largest deteriorations were observed for depressive (d = -0.22; 95% CI = -0.35, -0.08) and anxiety symptoms (d = -0.28; 95%CI - = -0.41, -0.14). Applying Bonferroni corrections, most group differences in outcomes had dissipated at follow-up, however, 'WISE Teens' participants continued to report significantly poorer quality of parent-child relationships relative to control (d = .16 for mother (95% CI = 0.01, 0.31); d = 0.17 for father (95% CI = 0.02, 0.33). While home practice w...
