Effects of early intervention on psychiatric symptoms of young adults in low-risk and high-risk families.

Effects of early risk and intervention on the psychiatric symptoms of young adults were studied. By means of a weighted risk index, 160 families with a baby born in 1975-1976 were classified as being at low or high risk. Half of the families attended a five-year family counseling program, the other half served as a control group. At age 20-21 years, the young adults from the counseled families had significantly fewer psychiatric symptoms than did those from the control families. A significant interaction between family risk and counseling was found. Implications for preventive intervention efforts are discussed.
