Program impacts were measured by assessing participant knowledge and several psychosocial factors related to self-management at baseline, 8 weeks, and 16 weeks. All items were evaluated for appropriateness for those with low educational attainment and health literacy. To assess participant knowledge, we used a 17-item survey that included 2 to 5 items related to several programspecific domains: hypertension, physical activity, nutrition, stress management, tobacco use, and medication management. Each item has one correct response and three distracters. The participant knowledge survey contains items from an item pool developed by project staff after reviewing documents developed by the NHLBI and the AHA. Knowledge survey items were ultimately selected by staff and health coaches together.
