Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <sec id="eat22333-sec-0001" sec-type="section"> <title>Objective</title> <p>Pediatric loss of control (LOC) eating is predictive of partial‐ and full‐syndrome binge eating disorder. The interpersonal model proposes that LOC eating is used to cope with negative mood states resulting from interpersonal distress, possibly on a momentary level. We therefore examined temporal associations between interpersonal problems, negative affect, and LOC eating among overweight adolescent girls using ecological momentary assessment (EMA).</p> </sec> <sec id="eat22333-sec-0002" sec-type="section"> <title>Method</title> <p>Thirty overweight and obese (≥85th body mass index (BMI) percentile; BMI: <italic>M</italic> = 36.13, SD = 7.49 kg/m<sup>2</sup>) adolescent females (Age: <italic>M</italic> = 14.92, SD = 1.54 y; 60.0% African American) who reported at least two LOC episodes in the past month completed self‐report momentary ratings of interpersonal problems, state affect, and LOC eating for 2 weeks.
