The researchers tested two hypotheses: (1) As long as a child is strongly attached to one parent, strong ties to the other parent play an insignificant role in reducing delinquency further; and (2) Single-parent homes are not associated with delinquency as long as the child is strongly attached to the custodial parent. The 1972 National Survey of Youth involved 1,395 interviews that solicited information on delinquent activities, peer group activities, school attitudes, and various family characteristics and attitudes. The sample consisted of boys (51.6 percent) and girls (48.4 percent) between the ages of 11 and 18. The hypotheses were not supported. Generally, the study found that children who are strongly attached to both parents have a lower probability of self-reported delinquency than children who are strongly attached to only one parent. It also determined that children who live in single-parent homes and are strongly attached to the custodial parent generally have a greater probability of committing delinquent acts than children who live in intact homes and are strongly attached to both parents. 3 tables and 31 references
