Purpose There is a dearth of information about factors related to physical activity among Mexican Americans with diabetes. Self efficacy and social support are associated with physical activity, however little is known about their role within different cultural groups. Design Focus groups were used to identify factors that motivate walking. Setting Two Mexican American communities located in Tucson, Arizona. Subjects Individuals who attended diabetes education. Intervention A community-based provider organized walking groups with people who previously attended diabetes classes. Walkers participated in focus groups exploring themes related to their experience. Measures Self efficacy, social support, and collective efficacy. Grounded theory was used to analyze focus group results using two rounds of analysis; the first identifying references to self efficacy and social support and the second adding collective efficacy as a theoretical basis for walking. Results Among 43 eligible participants, 20 participated in focus groups. Social support was expressed as commitment and companionship. Walkers demonstrated a high level of self efficacy for walking. Development of group identity/social cohesion was also a motivator to walk. Collective efficacy emerged as an applicable theoretical model encompassing these themes and their interrelationship. Conclusion Collective efficacy, or the belief that the group can improve their lives through collective effort, is a viable theoretical construct in the development of physical activity interventions targeting Mexican Americans with diabetes.

Minority group members’ participation in clinical research is essential for eliminating health disparities. Early recruitment procedures for a randomized control trial involving minority elders at local hospitals were unsuccessful, with challenges at hospital and individual levels. These challenges included referrals for home health care being written late during hospitalization, hospital staff reluctant to assist recruiters, ill minority elders and protective or unavailable caregivers. We met these challenges with evidence-based strategies, including changing inclusion criteria, increasing study staff, branding our study, using a consistently respectful manner, and pacing our process. After revising our approaches in various ways, we recruited close to our goal, with relatively good retention. Participants reported that benefiting the community rather than monetary reward was a strong motivator to join the study. Unexpected recruitment expenditures exceeded the recruitment budget. Our experiences include strategies that can be more cost-effective in future studies at both hospital and individual levels.
