Research Design & Number of Studies
Three randomised controlled trials (RCTs) were identified, conducted in Oregon, by the programme developer. The first trial population included adolescents aged 14-18 years, n=123 (Clarke et al., 1999); the second trial population included adolescents aged 14-18 years, n=59 (Lewinsohn et al., 1990) and the third trial population included adolescents aged 13-17 years, n=93 (Rohde et al., 2004).
Outcomes Achieved
Child Outcomes
• Statistically significant higher depression recovery rates in the treatment group than the waitlist control group (Clarke, et al., 1999) (Lewinsohn, et al., 1990)
• Significant improvement in behaviours targeted including anxiety, pleasant activities and depressagenic conditions by CWD-A (Lewinsohn, et al., 1990)
• Proportion of adolescents still meeting diagnostic criteria for depression was significantly reduced at post treatment compared to the waitlist control group and continued to decline over the 24-month follow-up period (Lewinsohn, et al., 1990).
• Significant reduction in parent-reported parent-adolescent conflict from post-treatment to 6-month follow-up for treatment groups (Lewinsohn, et al., 1990).
• Significant difference in participant reported depression scores and improved social functioning (Rohde, et al., 2004).
Parent Outcomes
• No parent outcomes were identified.
