And What About Siblings? A Longitudinal Analysis of Sibling Effects on Youth's Intergroup Attitudes.

Within the process of political socialization, the family is of particular importance. Apart from parents, however, little is known about the role of other close family members. The present study examined if siblings affect each other's intergroup attitudes (i.e., intolerance towards immigrants, social dominance orientation). Drawing on a sample of 362 sibling dyads (older siblings: M age = 17.77, 53.6% female; younger siblings: M age = 13.61, 61.3% female), the results showed that older siblings' intergroup attitudes predicted younger siblings' attitudes, but this effect was moderated by gender. Specifically, older siblings' intolerance and social dominance orientation were only found to affect their younger sisters, yet not their younger brothers. Although younger siblings' intergroup attitudes had no main effect on older siblings, a significant moderation by age indicated that younger siblings affected older siblings' social dominance orientation with increasing age. These moderation effects of age and gender were not mediated by the quality of family relationships. The findings also remained the same when parental intergroup attitudes were taken into account. While siblings were generally identified as an important agent of political socialization in youth, the results also highlight the necessity to further examine the mechanism that either facilitate or hinder sibling effects.

Who crosses the norms? Predictors of the readiness for non-normative political participation among adolescents.

This study investigated whether adolescents' readiness for non-normative political participation (i.e., readiness to confront social rules for political reasons) was predicted by their interpersonal problems (with parents, teachers, and classmates), low optimism, and political beliefs (political self-efficacy and distrust in public institutions). A structural equation model using two-wave longitudinal data from Czech high school students (N = 768; 54% females; age range at T1 = 14-17, M = 15.97; T2 data collected 1.5 years later) showed that the changes in adolescents' readiness for non-normative participation were predicted by their lower institutional trust. Interpersonal relationships or optimism had no cross-sectional or longitudinal effect on the readiness for non-normative participation. These results suggest that the main source of adolescents' readiness for non-normative political actions lies in their political beliefs, while the effect of adolescents' interpersonal problems is less clear.

Does family experience influence political beliefs? Relation between interparental conflict perceptions and political efficacy in late adolescence.

The study examined the relation between adolescents' interparental conflict perceptions and their political efficacy regarding local issues. Longitudinal data (age 15 and 17) from 444 adolescents were analyzed using structural equation modeling. Results showed that young people experiencing frequent interparental conflict reported an increase in depressive mood during late adolescence, which was associated with lower level of political efficacy. Moreover, adolescents who felt more efficacious when dealing with fighting parents felt more efficacious in local politics, even when controlling for personality traits and depressive mood. One possible explanation is that family perceptions generalize to politics because both contexts share certain similar features. Our results underscore that also seemingly nonpolitical experiences can matter in adolescents' civic and political development.
