Political involvement is accompanied by a range of positive and negative emotional experiences, including stress, sadness, anger, regret, purpose, and empowerment. These experiences may be especially potent during adolescence when youth are forming political opinions and are becoming more integrated within the political system. Little research has examined adolescents’ political emotional experiences and how these experiences are connected with concordant and future political engagement. Using an ecological momentary assessment design, this study tested cross-sectional and longitudinal within-day associations between adolescents’ political emotional costs and benefits and political engagement. Participants (N=291, Mage=16.09) completed four assessments of political emotional experiences (stress/sadness, anger, regret, empowerment) and multiple forms of political engagement (intent to protest, intent to vote, political interest, political efficacy, political participation) across one day. Greater political empowerment was cross-sectionally associated with all forms of political engagement and longitudinally associated with greater next-moment intent to vote and protest, political interest, and political efficacy. Greater political anger was associated with greater cross-sectional political interest, political efficacy, and political participation, but lower next-moment political efficacy. Greater political regret was associated with lower cross-sectional political efficacy and political interest and greater political stress/sadness was associated with greater cross-sectional intent to vote. Findings emphasize the importance of empowerment for adolescent political engagement and demonstrate nuanced connections between adolescents’ and subsequent involvement.
