Abstract
This article presents long-term effects of a randomized trial evaluating 2 standardized, manual-based prevention strategies for families with parental mood disorder: informational lectures and a brief, clinician-based approach including child assessment and a family meeting. A sample of 105 families, in which at least 1 parent suffered from a mood disorder and at least 1 nondepressed child was within the 8- to 15-year age range, was recruited. Parents and children were assessed separately at baseline and every 9 to 12 months thereafter on behavioral functioning, psychopathology, and response to intervention. Both interventions produced sustained effects through the 6th assessment point, approximately 4.5 years after enrollment, with relatively small sample loss of families (<14%). Clinician-based families had significantly more gains in parental child-related behaviors and attitudes and in child-reported understanding of parental disorder. Child and parent family functioning increased for both groups and internalizing symptoms decreased for both groups, with no significant group differences. These findings demonstrate that brief, family-centered preventive interventions for parental depression may contribute to long-term, sustained improvements in family functioning.
