Abstract
© 2021 International Society of Political PsychologyAcross the globe, collective action has been a notable driver of social change. Previous research has identified numerous psychological antecedents of collective action participation, such as group efficacy. The mobilizing influence of social norms, however, has been comparatively neglected. Among a nationally representative Chilean sample (N = 3328), a three-wave longitudinal study tested the relationship between the perceived frequency of family and friends' participation in social movements (norms of close social networks) and change in the frequency of participants' own engagement over time. Perceived efficacy of social movements to facilitate social change was tested as a mediator of this relationship. A fully constrained bidirectional cross-lagged panel model revealed that norms of close social networks significantly predicted social-movement participation over time. This longitudinal relationship was also significantly mediated by group efficacy. Direct reverse paths were also observed, with social-movement participation predicting norms of close social networks over time. Considering low degrees of political participation often seen in societies, these results suggest that utilizing the normative context to promote participation in social movements may prove fruitful in mobilizing the drive for social change.
