This study represents a thirty-year follow-up of five hundred twenty-four patients seen originally in a child guidance center for various reasons and one hundred patients chosen from the schools as controls. One fifth of the original child guidance population were later felt to have criteria sufficient for the diagnosis of sociopathic personality, as compared to two percent of the control group. The authors found no form of rejection specifically directed at the child to be associated with the development of sociopathic personality, but did find that divorced parents were more likely than nondivorced parents to have sociopathic behavior of the father and that of the child.
