The STAR-MAMA intervention builds on theoretical constructs found in Social Cognitive Theory, Theory of Planned Behavior, and Theories of Social Support found to be effective in weight loss, physical activity and dietary change, based on a recent meta-analysis and other studies. The investigators proposed development of STAR-MAMA will incorporate specific behavior change techniques associated with these theories, including: "self-regulatory" intervention techniques (specific goal setting, prompting self-monitoring, providing feedback on performance, goal review), self-efficacy building intervention techniques (motivational interviewing, using decisional balance and relapse prevention), individual tailoring techniques (information on content and resources), and culturally tailored social support, and which incorporates family needs.
