Context Matters: Construct Framing In Measures Of Physical Activity Engagement Among African American Women, Stephanie M. Mcclure, Travis Loux, Enbal Shacham, Eileen Gillespie, Denise Hooks-Anderson

Journal of Health Disparities Research and Practice

Assessment of psychosocial factors influencing health behavior typically privileges conceptual consistency (framing constructs similarly across contexts) over conceptual specificity (context-specific framing). Modest statistical relationships between these factors and health behaviors, and persistent racial disparities in health outcomes raise questions about whether conceptually consistent framing fully captures relevant predictors. Ethnographic studies suggest not - that perceptions influencing health behaviors are multifaceted and contextual. To test this, we added items querying contextualized predictors of intention to engage in leisure-time physical activity (LTPA) to a Theory of Planned Behavior (TPB)-based survey and examined the psychometrics of the adapted subscales. We measured internal consistency …
