Brief Summary:
The RAINBOW study is an NIH R01-funded randomized controlled trial to evaluate the clinical and cost effectiveness and implementation potential of a primary care integrated multicondition intervention program to help improve mood and weight for obese adults with clinically significant depressive symptoms. The ENGAGE study is a mechanistic investigation added to the main trial with funding through the NIH common fund for the Science of Behavior Change roadmap initiative. Beginning Jan 11, 2016, at least 100 of newly enrolled trial participants will be consented to undergo additional assays evaluating neurobiological mechanisms of self-regulation.

Detailed Description:
The large numbers of primary care patients affected by coexisting obesity and depression and common risk factors for diabetes and heart disease underscore the urgency of developing effective, accessible, and sustainable interventions that use an integrated, multicondition care management approach. The RAINBOW trial will rigorously evaluate the clinical and cost effectiveness and potential for "real-world" implementation of an innovative intervention that integrates a behavioral weight loss program and a collaborative stepped care program for depression, incorporates conventional clinic- and home-based modes of care delivery (e.g., office visits plus phone consults and take-home DVD), and leverages low-cost, wide-reach health information technologies (e.g., Web, secure email, and mobile texting). Beginning Jan 11, 2016, at least 100 of newly enrolled trial participants will also be consented to undergo additional assays evaluating neurobiological mechanisms of self-regulation, including emotional regulation, cognitive control and self-reflection. Given its focus on transforming primary care management of obesity and depression and common cardiometabolic risk factors to evidence-based, patient-centered care, as well as the likely scalability of the proposed intervention, the study has high potential for significant clinical and public health impact. Furthermore, elucidating the neurobiological mechanisms of self-regulation will significantly advance precision lifestyle medicine by enabling mechanism-targeted individualization of treatment.

  14. Regulation of emotion [ Time Frame: Baseline, 2, 6, 12, and 24 months ]
    Regulation of emotion will be measured using lab-based fMRI, virtual reality assays, and passive sampling of actual life behaviors using a Smartphone application. To measure regulation of emotion, fMRI assays include activation and connectivity values for approximately 300 brain regions, various physiological measures (heart rate, skin conductance, respiration rate) recorded on participant while performing tasks in fMRI scanner, performance and reaction times on various emotional web-based tasks, and online questionnaires administered with REDCap (emotional regulation questionnaire, early life stress questionnaire, and emotional regulation ratings success and strategies). Virtual reality assays include negative and positive emotion regulation head movement and emotional ratings. Passive sampling assays include passive experience sampling of 188 variables (e.g., mood-related word usage histograms) and Fitbit steps using a Smartphone application.

  15. Regulation of cognition [ Time Frame: Baseline, 2, 6, 12, and 24 months ]
    Regulation of cognition will be measured using lab-based fMRI, virtual reality assays, and passive sampling using a Smartphone application. To measure regulation of cognition, fMRI assays include activation and connectivity values for approximately 300 brain regions, various physiological measures (heart rate, skin conductance, respiration rate) recorded on participant while performing tasks in fMRI scanner, performance and reaction times on various cognitive control web-based tasks, and online questionnaires administered with REDCap (COPE Inventory for Cognitive Coping and Clutter Image Rating Scale). Virtual reality assays include cognitive control head movement, cognitive control score, and emotional ratings. Passive sampling assays include passive experience sampling of cognitive functions and Fitbit steps using a Smartphone application.
