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 had higher grades and fewer behavior problems than low-agreeable counterparts. High-agreeable adults reported less alcoholism and depression, fewer arrests, and more career stability than low-agreeable types. (Author/KB)
