Intergenerational transmission of risks for problem behavior.

The intergenerational transmission of risk factors for problem behaviors was examined across three generations. Two hundred fifty-four 2-year-old toddlers, one or two of their parents, and one grandmother of each toddler were studied. Grandmothers and parents were individually interviewed. Data were analyzed for the male and female toddlers combined. Correlations and hierarchical multiple regression analyses were performed. Findings indicate that the grandmother-parent relationship, parental personality attributes, marital harmony, and drug use and the parent-toddler relationship, predict the toddlers' behavior. The investigation provides evidence for a longitudinal, intergenerational process whereby the grandmother-parent relationship and the parents' personality and behavioral attributes are transmitted across generations through their association with the parent-child relationship.
