The relations between destructive interparental conflict (IPC) and three-to six-yearolds' ( N = 62) peer relations were examined as a function of child temperament and gender. Regression analyses indicated that effortful control moderated the relations of IPC with children's amount of peer interaction as well as with their problematic relations with peers. Specifically, high IPC was associated with low amount of interaction and high problematic relations for preschoolers low in effortful control, but it was related to high amount of interaction and low problems for those high in effortful control. Additionally, gender differences in the relations between IPC and the amount of peer interaction indicated that IPC was negatively related to the amount of interaction for girls but positively related to the amount for boys. The findings highlight the need for examining individual differences in the relations between IPC and the development of early peer relations.

The associations between maternal reports of positive marital quality (i.e., positive emotional expressions, constructive conflict, and mothers' marital satisfaction) and 3-6-year-olds' (N ¼ 62) positive peer relations were examined as a function of child temperament and gender. Although a zero-order correlation indicated that marital quality was unrelated to peer relations, a regression analysis indicated that high levels of positive marital quality were associated with more positive peer relations for preschoolers low in effortful control, but not for those high in effortful control. In addition, a moderating effect of gender revealed that the relationship between marital quality and positive peer relations was positive for girls but negative for boys. However, positive emotionality did not moderate the relations among marital quality and peer relations. The present study provides important preliminary findings that highlight the need for further study of the significance of positive marital relations for child development.

Although social support has been reported to have an impact on health behaviors in the general population, the present findings suggest that the benefits of social support may not apply to the smoking activities of LGBT individuals.
