OBJECTIVE: Disruptive behavior disorders (DBDs) represent a common motive for referral among youths. This meta-analysis aimed at estimating the efficacy of psychosocial interventions for DBD adolescents.
METHOD: A PRISMA-compliant systematic review of MEDLINE/PubMED/PsycINFO/Cochrane Central Register of Controlled Trials was conducted. Eligible studies were randomized controlled trials (RCTs) administering psychosocial interventions to DBD adolescents, published before April 5, 2020. From the initial set of 6,006 records, 17 RCTs involving 18 cohorts (16 publications) were subjected to a random-effect meta-analysis (involving sensitivity, subgroup, and meta-regression analyses). Primary and secondary outcomes were externalizing symptoms at RCT endpoint (i.e., standardized mean difference [SMD]) and acceptability (drop-out odds ratio [OR]), respectively. Risk of bias was assessed using the Risk of Bias 2 tool.
RESULTS: Seventeen RCTs, involving 1,954 adolescents, were included. Mean age was 14.09 (SD 1.33) years; 61% were male. Mean RCT duration was 12 weeks, with a mean follow-up of 8 (SD 3.98) months. Concern over risk of bias emerged in 12 studies, with high concern in 6. Psychosocial interventions had a large effect size at RCT endpoint (SMD=0.98, 95%CI -0.55 to -1.38, k=18) and were acceptable (drop-out OR=1.29, 95%CI 0.62-2.70, k=13). However, this beneficial effect did not persist at follow-up (SMD=-0.36, 95%CI 0.06 to -0.78, k=10). Family format was the most effective variable. No other clinically significant moderator was found.
CONCLUSION: Psychosocial interventions involving the families of DBD adolescents are effective and acceptable in the short term. Future studies should focus on strategies to achieve their long-term efficacy.
