Do Psychological Interventions Work for Psychosis in Adolescents?

backgroundThere is emerging evidence to show that psychological interventions such as cognitive remediation therapy (CRT), psychoeducation, family therapy, and group psychotherapies may be useful for adolescents with psychosis. The current review is on the effects of various psychological interventions for adolescents with psychosis compared with treatment as usual (TAU) or other psychological interventions.

methodsWe undertook a comprehensive search for all randomized controlled trials on the topic as per predefined criteria. For binary data, a standard estimation of risk ratio, and, for continuous data, the mean difference between groups were estimated. GRADE approach was used to assess studies. "Risk of Bias" was calculated, and finally random-effects model was used for analyses.

resultsThe review included 7 studies (n = 317). Two studies compared CRT and TAU with TAU alone. CRT showed improvement in short-term memory compared with those in the TAU group (relative risk 0.58, 95% CI 0.37 to 0.89, participants = 31, very low-certainty evidence). When comparing group psychosocial therapy with TAU, global state scores measured using Children's Global Assessment Scale (CGAS) were clearly higher in the intervention arm (mean difference 5.10, 95% CI 1.35 to 8.85, participants = 56, very low-certainty evidence) as compared with the TAU group. None of the other interventions were found to be significantly effective for the treatment of psychosis in adolescents.

conclusionsEvidence suggests that psychological interventions may have beneficial effects in the treatment of adolescents with psychosis, but the evidence is of low or very low certainty.
