Culturally and Linguistically Adapted Physical Activity Intervention for Latinas

The intervention includes regular mailings: weekly in month 1, biweekly in months 2 and 3, monthly in months 4 to 6, and a maintenance dose. Mailings consist of; 1) Manuals matched to the participant's current level of motivational readiness to change, based on TTM 2) Individually tailored computerized expert system feedback reports based on the participant's answers to monthly questionnaires. The computer expert system draws from a bank of over 330 messages developed from previous studies that address different levels of psychosocial and environmental factors affecting PA. 3) PA tip sheets addressing PA barriers specifically identified by Latinas in our formative research (e.g., caregiving duties, neighborhood safety).

Participants in the Enhanced Tailored arm will receive all the intervention components of the original tailored intervention, as well as: 1) additional print materials; 2) more in-depth tailored reports; and 3) text-messages. Self-monitoring was an important aspect in increasing PA in our previous trials however, participants were only asked to turn in the self-monitoring logs once a month. Based on the importance of self-monitoring and feedback from participants (R01NR011295; R01CA15994) that they wanted greater accountability and interactivity, we added a text-message component for self-monitoring.
