Psychosocial adjustment in children of alcoholics (COAs; N = 125) was examined before and at 3 follow-ups in the 15 months after their fathers entered alcoholism treatment. Before their fathers' treatment, COAs exhibited greater overall and clinical-level symptomatology than children from the demographically matched comparison sample, but they…

Data from an ongoing longitudinal study examined resilience (competent performance under adverse conditions) in a community sample of children of alcoholics (COAs n=216) and matched controls (n=201). The study examined the prevalence of competence and whether the relation of competence to internalizing and positive affect differed for COAs and…

Data from a 25-year study of 194 individuals indicated that teacher and peer reports of aggression, compliance, and self-control at age 8 distinguished high-agreeable from low-agreeable 33-year-olds. High-agreeable childhood types had fewer disobedience and concentration problems than low-agreeable childhood types. High-agreeable childhood boys…
