The effects of neighborhood proportion of single-parent families and mother-adolescent relationships on adolescents' number of sexual partners

Using both individual-level and census-level data, this study predicts the number of sexual partners reported by male and female adolescents from the quality of their mother relationship and neighborhood proportion of single-parent families. Both predictors were associated with number of sexual partners for both males and females in OLS analyses. However, in Repeated Measures analyses of females, neighborhood proportion of single-parent families was not significant. In both OLS and Repeated Measures formats models with individual-level single-parent family status, race, mothers' education and family income variables, neighborhood proportion of single-parent families was not significant for either gender. Interaction models found that neighborhood proportion of single-parent families moderated the influence of mother relationship on the number of sexual partners in OLS analyses for both sexes, but only for males in the Repeated Measures format. The direction of these two-way interactions varied significantly by gender-in both OLS and Repeated Measures. Mother relationships were more influential for females in neighborhoods with fewer single-parent families. In contrast, mother relationships were more influential for males in neighborhoods with more single-parent families.
