So far, there are few evidence-based recommendations about how to implement and evaluate community capacity building approaches. ACTION for men (A4M) is a project designed to build and evaluate capacities for health promotion in three rural communities in Bavaria, Germany, via a participatory approach including multiple community stakeholders. The project specifically aims at improving physical activity (PA) in men over 50 years of age (50 plus). Methods and Analysis As a strategy to build the communities’ capacities, we set up and facilitate a stakeholder group in every community over a period of one to three years. In regular meetings, the group members are motivated to actively participate in planning and implementing PA programs for men 50 plus. The facilitation systematically addresses key domains of community capacity (e.g. critical awareness, problem assessment, resource mobilization). The evaluation of the capacity building processes is carried out using a mixed-methods design. Evaluation instruments consist of structured documenta-tions and face-to-face interviews with stakeholder group participants (and drop-outs) as well as a pre-post-test using a standardized questionnaire in order to detect activity-related changes in men 50 plus from the involved communities. Discussion Building community capacity for health promotion programs is the primary aim in A4M, and thus differs from previous research in which capacity is mostly a means to an end or an “incidental” re-sult of a health promotion program. Therefore, A4M is expected to deliver important findings about how to implement and evaluate capacity building processes for health promotion, as well as how to address physical activity in community settings.
