Research Aimed at Improving Both Mood and Weight


Trial ID: NCT02246413


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.
