The overarching goal of this project is to develop a culturally congruent intervention to increase levels of physical activity among sedentary Latinas (i.e., Latina/Hispanic women). The first phase will involve culturally and linguistically modifying an existing evidenced-based intervention, founded on the Transtheoretical Model and Social Cognitive Theory, to target sedentary Latinas. Then, we will conduct a pilot randomized clinical trial to test whether the culturally-modified individually tailored intervention increases physical activity levels in comparison to standard care comprised of bilingual health education booklets.
