7. Project Summary/Abstract Overweight and obesity have reached epidemic proportions in the United States, proving to be a very difficult health challenge for both patients and the physicians who care for them. Excess weight is a major contributor to heart disease, stroke, and type 2 diabetes. Addressing overweight and obesity in clinical visits is critical to treating and preventing these obesity-associated diseases. However, Weight Management Counseling (WMC) uptake is low, and physicians report lack of training as a critical barrier to WMC. Residency training is a crucial time to influence physicians' current and future practice, yet there is no evidence-supported WMC curriculum for residents. Informed by two pilot studies, MRWeight will use spaced-education to train residents to deliver WMC using the 5As framework (Ask, Advise, Assess, Assist, Arrange) and patient-centered counseling. As such, MRWeight will be delivered in short segments and spaced over 12 months using four components: didactic session 1 – a discussion of WMC foundational concepts; 3Ps program (Prepare, Practice, Process) – an email program using the Video-based Communication Assessment (VCA) to facilitate practice of challenging cases; didactic session 2 – a discussion of key barriers to practicing WMC; and email reinforcement of concepts covered in the preceding components. Each component, guided by Social Cognitive Theory (SCT), is designed to build on and reinforce the training provided by the other components. Using a pair-matched group randomized controlled trial (RCT) including 8 Internal Medicine residency programs, we will test the MRWeight intervention with 3 cohorts of postgraduate year 1 residents followed for 18 months. Comparison arm residents will be emailed the PowerPoint of a foundational course on WMC, but unlike those in the Intervention, comparison sites will not include the didactic sessions or the 3Ps program. Our aims are: Aim 1 will evaluate the effectiveness of the MRWeight Intervention for increasing residents' WMC skills at 12 months; Aim 2 will evaluate residents' self- reported adoption of WMC skills in their encounters with patients in clinical practice at 18 months; Aim 3 will explore possible mechanisms (mediators) and moderators of the intervention's effect on Aim 1 and 2 outcomes (residents' WMC skills and adoption). The study will be the first large trial to test a curriculum that has been integrated into Internal Medicine residency programs for teaching WMC skills. The multi-PIs (Drs. Ockene and Sadasivam) will build on 36-years of successfully conducting large, randomized trials to evaluate training programs, including those that taught the 5As and patient-centered counseling for WMC, in 18 medical schools, 10 residency sites, and 10 primary care settings. This study is timely, given public health momentum strongly advocating for physician training and involvement in WMC and the dissemination and implementation of clinical guidelines for obesity treatment.

8. Project Narrative Overweight and obesity affect a large majority of Americans, increasing their risk for multiple chronic illnesses. It is recommended that physicians provide weight management counseling (WMC) to patients having overweight or obesity, but physicians have limited WMC training. Residency is an ideal time to teach physicians WMC skills, but residency programs lack an evidence-based curriculum to support this need. Our study addresses this gap by testing MRWeight, an innovative technology-assisted spaced education program designed specifically for teaching WMC to medical residents.
