OBJECTIVE: This study examined the factor structure of five binge-eating symptom items and identified the social contexts and food types associated with these symptoms in adolescents using ecological momentary assessment (EMA).
METHODS: Seventy-four adolescents aged 13-17 completed ten days of EMA, including signal-contingent prompts and event-contingent eating episode prompts. When recording eating episodes, adolescents completed measures on their current social context, food and drinks consumed, and binge-eating symptoms during the episode. Primary analyses included multilevel exploratory factor analysis of five binge-eating symptom items and generalized linear models of associations between social contexts and food types with binge-eating symptoms.
RESULTS: A two within-subject (i.e., overeating and loss of control eating [LOCE] subscales) and one between-subject factor solution fit the data. Within-subjects alone versus not alone was associated with lower overeating (p = .010) and within-subjects family versus not with family was associated with higher overeating (p = .033). Between-subjects family context was associated with lower LOCE (p = .008), while between-subjects peers/friends context was related to higher LOCE (p = .002) and overeating (p = .003). Both within- and between-subjects consumption of sweet food was associated with increased LOCE (p = .03 and p < .001, respectively) and overeating (p = .02 and p = .003, respectively). Within-subjects consumption of salty/fried food and pizza/fast food was both significantly associated with higher LOCE (p < .001 and p=.021, respectively) and overeating (p=.041 and p < .001, respectively). Within-subjects consumption of sweetened beverages was linked to higher overeating (p < .001), while water consumption was associated with lower overeating (p = .002).
CONCLUSIONS: Implications include the use of context-specific nutrition and social interventions in reducing adolescent binge eating.
