Interventions

Vida SanaBEHAVIORAL

Vida Sana is a Diabetes Prevention Program-based, culturally-adapted intervention that will have 2 distinct stages: The intensive treatment stage will implement a culturally adapted year-long Group Lifestyle Balance curriculum. The curriculum uses a goal-based approach to promote positive outcome expectancies and foster self-efficacy. The maintenance stage will be focused on (1) facilitating continued behavior change; (2) fostering participants' self-efficacy and independence; and (3) reinforcing problem-solving and behavior maintenance skills. These will be done via secure e-messaging.

Vida Sana

Patients assigned to this group will continue medical care as usual. That is, they will continue to see their primary care provider and any specialist he/she may recommend. They may also access additional health education resources available at the Palo Alto Medical Foundation. They will continue to receive general age and gender-appropriate reminders of health maintenance tests/exams and immunizations, per Palo Alto Medical Foundation standard practice.

Usual Care Only
