Supportive Social Contexts and Intentions for Civic and Political Participation: An Application of the Theory of Planned Behaviour

We investigated how general social support from family, friends and acquaintances, and community predicted intentions for civic (e.g. volunteering) and political (e.g. petitioning) participation via the constructs specified in the theory of planned behaviour. Participants were young adults living in the former East Germany, a post‐communist region, who were surveyed by telephone in 2010 (N_civic = 695, N_political = 694). Civic participation was perceived more favourably than political participation. Supportive family predicted intentions for civic participation; supportive community services predicted both types of intentions; and supportive friends and acquaintances had no significant effects. The mediating variables were subjective norms and perceived behavioural control, but not attitudes. All effects were controlled for sociodemographic variables, richness of the social network, and past experience of civic and political participation. Findings underscore the role of supportive community in fostering both civic and political participation. Copyright © 2014 John Wiley & Sons, Ltd.
