This paper describes the development and preliminary efficacy of a pro
gram designed to prevent depressive symptoms in at-risk 10-13 year-old
s, and relates the findings to the current understanding of childhood
depression. The treatment targets depressive symptoms and related diff
iculties such as conduct problems, low academic achievement, low socia
l competence, and poor peer relations, by proactively teaching cogniti
ve techniques. Children were identified as 'at-risk' based on depressi
ve symptoms and their reports of parental conflict. Sixty-nine childre
n participated in treatment groups and were compared to 73 children in
control groups. Depressive symptoms were significantly reduced and cl
assroom behavior was significantly improved in the treatment group as
compared to controls at post-test. Six-month follow-up showed continue
d reduction in depressive symptoms, as well as significantly fewer ext
ernalizing conduct problems, as compared to controls. The reduction in
symptoms was most pronounced in the children who were most at risk.
