Abstract
OBJECTIVE: High-risk studies of psychiatric disorders in parents and offspring that include 3 generations are uncommon. Multigenerational studies can be clinically useful as they can provide information for risk prediction from one generation to another for the development of empirically based interventions. Using a high-risk design, this study examines the association of grandparent major depressive disorder (MDD) and parent MDD with psychopathology in grandchildren. METHOD: Using Cox proportional hazards in a sample of 90 grandchildren at high and low risk for depression by virtue of their grandparents' and parents' depression status, the authors examined the risk for offspring depression and anxiety. RESULTS: Grandparent and parent MDD were associated with grandchild anxiety (relative risk [RR] = 5.51 and R = 3.09, respectively). Grandchildren with both a depressed parent and grandparent had the highest risk for anxiety. Parental MDD is associated with an increased risk for grandchild disruptive disorder (RR = 10.77). Forty-nine percent of the grandchildren in families in which both the parent and grandparent were depressed had some form of psychopathology. The grandchildren from those families were the most impaired. CONCLUSIONS: Prepubertal-onset anxiety disorder is a risk factor for the later development of clinically significant recurrent MDD across several generations of families at high risk for depression. Parental impaired functioning increases the risk for disruptive disorders. Children in families with multiple generations of depression are at particularly high risk for some form of psychopathology.
