Brief summary
The goal of this clinical trial is to learn about cardiovascular disease risk among adolescent girls with overweight/obesity. The main questions this trial aims to answer are: 1. Does an acceptance-based healthy lifestyle intervention demonstrate more weight loss than a health education intervention? 2. Does an acceptance-based healthy lifestyle intervention show more improvements in participants' physiological, health-related, and psychological factors compared to a health education intervention? Participants in this trial will: 1. Engage in treatment for 6-months, comprising of a mixture of in-person and remote group sessions, occurring at Drexel University or over a video-conferencing platform. 2. Complete various assessments. These include self-reported questionnaires, measures of weight, height, body composition, blood pressure, and blood lipids, and wearing of smart watches to measure sleep and physical activity. Researchers will compare the acceptance-based and health education intervention groups to see if the acceptance-based treatment will indeed be effective in improving participants' health outcomes.
Detailed description
Overweight/obesity (OW/OB) affects 14 million adolescents in the U.S. and disproportionately affects girls and racial/ethnic minorities while increasing their risk of cardiovascular disease (CVD) and type 2 diabetes. Adolescents demonstrate limited self-regulation skills, which are essential for adhering to diet and physical activity goals. Adolescents must contend with pervasive biological and environmental cues (e.g., cravings, labor-saving devices) that promote overeating and sedentary behavior. There is a critical need for interventions that teach self-regulation to enable adolescents to respond adaptively to these cues. Acceptance-based therapy (ABT) is an innovative approach that focuses on self-regulation skills, mindfulness, and increasing tolerance of uncomfortable internal experiences. There is strong evidence for ABT as an effective weight loss intervention for adults. The investigators conducted formative work using an adolescent-engaged approach to develop, implement, and feasibility test an ABT intervention for adolescent girls with OW/OB. The objective of this proposal is to test the efficacy of a novel ABT weight loss intervention tailored for adolescent girls with OW/OB. This trial is the first to investigate ABT tailored for adolescent girls with OW/OB. The investigators will conduct a 6-month, randomized controlled trial comparing ABT with a health education comparison for 14- to 19-year-old adolescent girls with OW/OB, including ≥40% racial/ethnic minorities. To enhance scalability, interventions in both conditions will be delivered by bachelor's level paraprofessional weight loss coaches, treatment will occur in a hybrid of in-person and remote sessions, and the trial will take place in an outpatient community clinic. Assessments will be conducted at baseline, mid-treatment (month 3), post-treatment (month 6), 6-month follow-up (month 12), and 12-month follow-up (month 18), for a total study time of 18 months. The primary hypothesis is that adolescents randomized to ABT will exhibit significantly greater improvements in BMI z-score post-treatment compared to a health education comparison (HE). In the secondary aims, the investigators hypothesize that at post-treatment and 6- and 12-month follow-up, adolescents randomized to ABT will exhibit significantly greater improvements in their physiological, behavioral, and psychological risk factors compared to HE.
Interventions
BEHAVIORALAcceptance-based Treatment (ABT)
Participants will be provided with psycho-education, skill-builders, and other coaching to promote weight loss and healthy lifestyle changes.
BEHAVIORALHealth Education (HE) Comparison
Participants will be provided with psych-education and resources to promote weight loss and healthy lifestyle changes. They will not be provided with directives.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| BMI z-score change | Month 6 | Compare ABT vs. HE on BMI z-score change at post-treatment (month 6). The investigators hypothesize a significantly greater decrease in BMI z-scores in the ABT relative to HE. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physiological - Adiposity | Month 6, month 12, month 18 | Compare change in percent body fat in ABT relative to HE |
| Physiological - Blood pressure | Month 6, month 12, month 18 | Compare change in diastolic and systolic blood pressure in ABT relative to HE |
| Physiological - Blood lipids | Month 6, month 12, month 18 | Compare change in total blood lipid levels in ABT relative to HE. HDL, LDL, and total cholesterol will each be examined. |
| Health-related behaviors - dietary intake | Month 6, month 12, month 18 | Compare change in dietary intake in ABT relative to HE. Dietary intake will be measured with a VioScreen Food Frequency Questionnaire. |
| Health-related behaviors - physical activity | Month 6, month 12, month 18 | Compare change in physical activity in ABT relative to HE. Physical activity will be measured with a smart watch. |
| Psychological - Quality of life | Month 6, month 12, month 18 | Compare change in quality of life, in ABT relative to HE. Quality of life will be measured with the Quality of Life Inventory. |
| Psychological - Depression | Month 6, month 12, month 18 | Compare change in depression in ABT relative to HE at all time points. Depression will be measured using Beck's Depression Inventory-II. |
| Psychological - Disordered eating | Month 6, month 12, month 18 | Compare change in disordered eating in ABT relative to HE at all time points. Disordered eating will be measured using the Eating Disorder Examination Questionnaire. |
| Psychological - Psychological flexibility | Month 6, month 12, month 18 | Compare change in psychological flexibility in ABT relative to HE at all time points. Psychological flexibility will be measured using the Acceptance and Action Questionnaire II. |
