• In Event: Poster Session & Ice Cream Social

Abstract

Deviant collective actions are a growing global concern, highlighting the need to understand their psychological, social, and demographic influences. This meta-analysis examines the psychological, social, and demographic factors that influence participation in deviant collective actions. Specifically, it investigates (1) the sociopsychological mechanisms that drive individual involvement, (2) the role of social media in mobilization and dissemination, and (3) the influence of contextual factors such as age, political affiliation, and economic conditions. A systematic search following PRISMA guidelines in PsycINFO, Web of Science, and Scopus databases was conducted. Eligible studies used quantitative measures to assess collective action, examined psychological mechanisms (e.g., identity, emotions, efficacy), explored social media’s role, or analyzed contextual determinants. Studies were limited to peer-reviewed journal articles published in English, Portuguese, or Spanish with adult participants (18+). Exclusion criteria included literature reviews, qualitative studies, policy-focused analyses, and research on non-social activism. Data extraction and analysis are ongoing, and preliminary findings suggest emerging patterns in collective action's psychological and contextual drivers. Full results, including effect sizes and moderator analyses, will be presented. The findings will contribute to a deeper understanding of collective action dynamics, with implications for mobilization theories, public policy, and social interventions.
