Study Overview
Brief Summary
The purpose of the proposed study is to pilot a 6-month, cognitive-behavioral binge eating intervention, Appetite Awareness Training (AAT) to reduce binge eating and prevent weight gain for Black women with a BMI > 25 kg/m^2 and with weekly binge eating episodes. Intervention participants will receive a 8-week group AAT intervention, and will also receive bluetooth-connected scales for daily weighing. Participants will also receive tailored feedback on self-weighing frequency and weight change. The investigators will follow-up with participants at six months.
Detailed Description
Aim 1. Using an experimental design, examine the feasibility and acceptability of 6-month AAT (N=40) in North Carolina. Forty overweight and obese (BMI ≥ 25 kg/m^2) community-based Black women will be randomized to the AAT intervention or wait-list control (who will eventually receive the intervention). AAT participants will meet weekly for 8 weeks, followed by a 4-month period of daily weighing and weekly tailored feedback only. The study will examine the following: recruitment feasibility, attendance/retention, adherence, satisfaction, and barriers to completion.
Aim 2: At 4 and 6 months, compare changes in (a) binge eating, eating self-efficacy, and depressive symptoms and (b) weight, blood pressure, and waist circumference for participants in the intervention vs. control group.
H_1: Participants in the AAT intervention will report less binge and overeating and gain less weight than those in the control group at 2 and 6 months.
Secondary aim: Examine characteristics (e.g., baseline BMI, severity of binge eating, frequency of self-weighing) related to change in binge eating and weight.

Arms & Interventions
Appetite Awareness Treatment (AAT) + Lifestyle Modification (LM)
Participants will receive an 8-week Appetite Awareness Training (AAT) program using a group format, will be provided a smart scale (with bluetooth connection) and instructions to weigh themselves daily. Participants will also be provided with weekly tailored feedback on self-weighing frequency and weight change. Assessment will be conducted at 0, 2, and 6 months.
Intervention: Appetite Awareness Treatment + Lifestyle Modification (Behavioral)
Control
Control group participants will receive no intervention in months 1-6, but will be offered the chance to receive an abbreviated form of AAT (4 weeks) following the 6-month assessment.
Outcomes
Primary Outcomes
Feasibility (Recruitment): Total Number of Participants Who Were Eligible and Enrolled in the Study
Time Frame: Month 6
Recruitment is defined as the number of potential participants screened for study eligibility versus the number of persons who enrolled in the study.
Feasibility (Retention): Percentage of Participants Retained in the Study
Time Frame: Month 6
Percentage of participants retained in the study following enrollment through month 6
Feasibility (Attendance): Percentage of Sessions That Were Attended
Time Frame: Month 2
Each session attended by participants was captured. The number of sessions attended for each participant were summed and then divided by the number of total participants and multiplied by 100.
Secondary Outcomes
- Median Weight Change From Baseline to Month 6(Baseline, Month 6)
- Median Weight Change From Baseline to Month 4(Baseline, Month 4)
- Mean Objective Binge Eating Episodes(up to 6 months)
- Mean Change in Binge Eating Scale Score From Baseline to Month 2(Baseline, Month 2)
- Mean Change in Binge Eating Scale Score From Baseline to Month 6(Baseline, Month 6)
