Community Health Advisors' Characteristics and Behaviors, Role Performance, and Volunteer Satisfaction in a Church-Based Healthy Eating and Physical Activity Intervention.

Community Health Advisors (CHAs) contribute to health promotion program effectiveness, but their role in faith-based programs is understudied, and little is known about their role performance or satisfaction. In a dissemination and implementation study, 19 CHAs were trained to provide healthy eating (HE) and physical activity (PA) program training to church committees. Of these, 17 CHAs trained 347 attendees from 115 churches. Thirteen CHAs remained for the 12-month period and provided telephone-based technical assistance (TA) to churches. To evaluate their experiences and satisfaction, CHAs completed questionnaires at baseline and 12 months. Staff observers and church committee members evaluated CHAs' effectiveness as trainers. There were no significant changes in the CHAs' own body mass index, PA, fruit and vegetable intake, or self-rated health but significant increases in their perceived knowledge of PA (p = 0.01) and HE (p = 0.02). CHAs reported high agreement regarding the quality of their training for the role and moderate volunteer satisfaction on average but thought that the time required of them was somewhat more than expected, though they were interested in volunteering for a future, similar role. Church committee members agreed with CHAs' effectiveness as trainers and the helpfulness of the TA calls. Staff observers rated CHAs' as having covered 87.8% of church training content and agreed that, on average, the CHAs were effective trainers. Assessing CHAs' availability, clear communication about the time requirements, and over-recruitment to offset attrition and decrease the workload may be needed to improve retention and support satisfaction.
