Abstract
Purpose
Body dissatisfaction (BD) is supported as a maintenance factor for eating disorders (EDs) characterized by binge eating (BE). Although it is traditionally conceptualized as a trait construct, ecological momentary assessment (EMA) studies have shown that it fluctuates within-day and that momentary elevations in BD prospectively predict near-time ED behaviors. However, less is known about the contextual factors that precipitate these fluctuations in BD.
Methods
The current study thus sought to examine whether certain internal (i.e., negative affect, shape/weight-related cognitions) and environmental (i.e., attending social events, being exposed to thin-ideal media, spending time on social media) factors prospectively predict momentary elevations in BD in females with BE. Participants (n = 25) completed an EMA protocol over 14 days.
Results
Data on BD and internal and environmental factors were analyzed using generalized estimating equations. Results showed that (1) greater than one’s usual negative affect and shape/weight-related cognitions, and (2) spending time on social media prospectively predicted momentary elevations in BD. Interestingly, attending social events prospectively predicted momentary reductions in BD.
Conclusion
These findings may have important implications for conceptualizing and managing BD to prevent ED behaviors.
