Purpose: The purpose of the study is to test the effects of a culturally tailored family-based self-management education and social support intervention on family social capital with Mexican American (MA) adults with type 2 diabetes (T2DM) and their family member. Methods: Using a 2-group, experimental repeated-measures design, 157 dyads were randomly assigned to an intervention (group education and social support, home visits, and telephone calls) or a wait list control group. Data were collected at baseline, immediately postintervention (3 months), and 6 months postintervention. A series of 2 × 3 repeated-measures analyses of variance with interaction contrasts were used to test the hypotheses regarding the differential effects on family social capital. Results: Social capital outcomes included social integration, social support, and family efficacy. Social integration scores, high for family members and friends and low for community engagement, did not change over time for participants or family members. Participants perceived high support from family for physical activity with an immediate increase postintervention and moderate sabotage for healthy eating with no change over time. A sustained intervention effect was noted for family efficacy for general health and total family efficacy in participants and family members. Conclusions: This family-based culturally tailored intervention demonstrated the potential to improve social capital, specifically social support for physical activity and family efficacy for diabetes management for MA adults with T2DM. Ongoing research that examines the family as a critical context in which T2DM self-management occurs and that targets strategies for sustained family social capital outcomes for T2DM is needed.
