Abstract: Community-based participatory research (CBPR) methodologies align closely with the field of community psychology. System dynamics group model building (SD GMB) represents a CBPR-grounded approach that is centered on collaborating with stakeholders to develop a shared understanding of the dynamic complexity of a community problem, represented as a system dynamics (SD) model, and identifying potential solutions. Much is still unknown regarding the value of SD GMB for improving systems thinking capacity among community stakeholders. Therefore, this study evaluates systems thinking capacity among 32 stakeholders who participated in SD GMB workshops from two recent studies. Stakeholders completed a baseline survey before the first SD GMB workshop session and a final evaluation survey following the last session. This survey included a validated systems thinking scale (Dolansky et al., 2020) and a "systems thinking knowledge quiz" (only administered during the baseline survey) developed by the research team to assess stakeholder knowledge of key concepts. Among all stakeholders, the average systems thinking quiz score was nearly 45%, and knowledge quiz scores were higher among stakeholders who were older in age, had lived experience, were in healthcare provider or academic researcher/data professional roles, represented the nonprofit or grassroots sectors, reported prior experience with SD GMB, or did not attend the pre-session orientation. Overall, stakeholders' pretest scores and post-test scores did not demonstrate a statistically significant difference; however, increases in systems thinking mean scores were observed among stakeholders who were younger in age, had lived experience, were in community-based nonprofit staff roles, represented nonprofit or grassroots organizations, did not have prior SD GMB experience, or did not attend orientation. These findings underscore the importance of adopting a more differentiated and context-sensitive approach to evaluating SD GMB interventions. Future research should further explore how participatory modeling fosters systems thinking capacity across different stakeholder groups.
