Improving Sleep, Decision-Making, and Eating in Adolescents With Obesity
Purpose
This study is being performed to understand the effects of a lifestyle modification and sleep intervention on weight loss outcomes in adolescence. The main question the study aims to answer is: - What are the initial effects of a lifestyle modification and sleep intervention, including effects on weight, eating behaviors and dietary intake, and sleep? Participants will: - Participate in remote, group-based, weekly weight loss and sleep coaching for 16 weeks. - Complete study assessments at baseline (pre-intervention), mid-intervention, and post-intervention. - Complete daily sleep diaries for three 7-day periods at each assessment point.

Experimental Group Intervention |
All participants will receive group-based lifestyle modification and sleep treatment (16, 90-minute sessions over 16 weeks). All sessions will be delivered on Zoom (remotely) to small groups (n=5-10 each) of participants. The intervention involves lifestyle modification content (e.g., nutritional education, physical activity education, stimulus control, goal setting) and sleep content (e.g., psychoeducation regarding sleep and eating behavior, sleep tracking, establishing regular sleep-wake times). |

Detailed Description
In this study, the investigators will develop, refine, and test a 16-session group-based lifestyle modification intervention for adolescents with overweight and obesity augmented with a sleep intervention. The investigators will develop the manual and pilot the intervention in an initial set of adolescents (n=10). The investigators will collect feedback from adolescents, parents, and clinicians, which will inform manual refinements. The investigators will complete an open trial (n=40) of the refined manual. For both phases, the investigators will recruit adolescents (ages 14-18) with overweight or obesity who endorse at least 1 type of sleep disturbance (i.e., too little, poor quality, poorly timed, or inconsistent sleep). Assessments of sleep, decision-making, problematic eating behaviors, energy intake, and weight will occur at baseline (week 0), mid-intervention (week 8) and post-intervention (week 16).
