This study uses data from the 1982 National Survey of Family Growth to ascertain whether family interaction can avert adolescent sexual activity, pregnancy, childbearing and parenthood. The results obtained from using logistic regression procedures indicate that the family may be effective in increasing adolescents' use of contraceptives and selection of abortion or adoption as alternatives to parenthood. Family interaction, however, was not associated with forestalling adolescent sexual activity or with providing for the well-being of the adolescent and her child and it is unlikely that a policy based solely on family interaction will be effective. Characteristics associated with effectiveness in preventing adolescent pregnancy included race, religion, residence, mother's education, the adolescent's age and family income.
