ABSTRACT
The authors analyzed affectivity in children from same-sex parent and single-parent families in comparison with children who live in heterosexual family structures. Data from 165 questionnaires were analyzed by descriptive statistics, bivariate analysis, and multivariate analysis. In the raw bivariate data, the highest positive affectivity was seen in children who live in the model formed by 2 mothers. By adjusting the multivariate analysis model, only the level of education of the parents remained an influencing variable, showing that the children of conventional families scored higher for negative affectivity.
