Long-term outcomes of psychological interventions on children and young people's mental health: A systematic review and meta-analysis.

ABSTRACT:

Background

Over 600 RCTs have demonstrated the effectiveness of psychosocial interventions for children and young people's mental health, but little is known about the long-term outcomes. This systematic review sought to establish whether the effects of selective and indicated interventions were sustained at 12 months.

Method

We conducted a systematic review and meta-analysis focusing on studies reporting medium term outcomes (12 months after end of intervention).

Findings

We identified 138 trials with 12-month follow-up data, yielding 165 comparisons, 99 of which also reported outcomes at end of intervention, yielding 117 comparisons. We found evidence of effect relative to control at end of intervention (K = 115, g = 0.39; 95% CI: 0.30-0.47 I2 = 84.19%, N = 13,982)
