Drawing from positive psychology and journalism studies, this article proposes constructive advocacy as a theoretical and methodological arena for public interest communications. Through a case study of a transnational advocacy network, this research employs a thematic analysis of in-depth interviews with 40 activists, exploring positivity and solutions-based information for social change. This study contributes to the new body of literature on public interest communications, opening up theoretical and methodological arenas in understanding how activists plan and execute strategic communication.
