Social skills and depressive symptoms across adolescence: social support as a mediator in girls versus boys.

The current population-based study of Norwegian adolescents examined gender-specific patterns in the prospective association between social skills in early adolescence (age 12.5; n = 566) and changes in depressive symptoms from early to late adolescence (age 16.5; n = 375). Further, a potential mediation effect of social support (from peers, parents, and teachers) in middle adolescence (age 14.5; n = 456) was examined. The findings indicated that low levels of social skills in early adolescence predicted increases in depressive symptoms for both girls and boys. Low levels of friend support in middle adolescence mediated this relationship for girls, but not boys. The findings underline the importance of including social skills training in primary programs designed to prevent development of depression. Preventive programs should also include actions on how girls can cope with interpersonal difficulties.
