HE public is greatly concerned with family breakdown. I t is disturbed T. at the rising divorce rate. It is alarmed at reports of the increasing rate .of juvenile delinquency. It is disposed to hold parents responsible for the delinquency of children and to blame the parents of young couples if their marriage disintegrates. It advocates legislation to punish parents for their children's delinquency.This interdisciplinary organization, the American Orthopsychiatric Association, was founded to discover the causes of human behavior and to apply this knowledge in prevention and rehabilitation. Its members do not think of family breakdown in terms of assessing blame and punishment. By their training and experience they are looking for causative factors in the individual and in the community and for the best methods for the prevention and treatment of family breakdown. This paper will discuss three factors in family breakdown: the economic, the cultural, and the social.No one can doubt that economic factors are related to family breakdown.The studies by Bradley Buell and his associates give eloquent proof of this relationship. Rates of nonsupport, desertion, divorce, mental disorder, infant mortality, and juvenile delinquency are highest in neighborhoods of the lowest income and of the worst housing.But what is the nature of the relation between economic privation and family breakdown? It is seldom, if ever, direct. If it were, all families in poverty would experience family breakdown. Every social worker knows that this result does not follow. Studies show that well-integrated flexible families withstood our last depression where unintegrated unadaptable families failed to adjust (2, 3). Family breakdown results directly, as Dr. Lippman has emphasized, from the strains and conflicts in the interpersonal relationships of husbands and wives, parents and children.
