Nine studies (at least 158 youths) were included in the review: one randomised controlled trial (RCT), one quasi-experimental study, two pilot pre-post studies, two case studies, one case report and two descriptive studies. Most studies had small sample sizes and provided a low level of scientific evidence.
Seven of the nine studies reported positive effects of a community integration intervention. Improvements were reported for social relationships (four studies), home, social and community participation (one study), initiative in seeking vocational opportunities (one study), social competence (two studies) and social behaviour (two studies including one RCT). None of the included studies reported any negative effects for patients with regard to the interventions. Further were details reported in the review.
