Participation in this study will last 1 year and include three parts. In the first part, participating children and their families will complete research interviews and questionnaires about the child's mood, behavior, beliefs, and problems. Parent participants will also provide information on the family background of mood or anxiety problems. In the second part, participants will be randomly assigned to receive one of two treatments: FFT or brief educational treatment. Participants receiving FFT will complete 12 therapy sessions in which parents, children, and siblings learn how to cope with mood disorders, new ways to talk to each other, and strategies for solving family problems. FFT sessions will occur weekly for the first 8 weeks and then every other week for the next 8 weeks. Participants receiving brief educational treatment will complete diagnostic assessments and a 1-hour individualized feedback session, and they will be given a workbook about childhood mood disorders. A counselor will be available to all participants, in case of emergencies, for the full study year. All participants will also be provided with standard pharmacotherapy as needed. In the third part of the study, participants will complete follow-up assessments every 4 months for 1 year. Assessments will include interviews and questionnaires similar to those completed in the first part of the study.
