Abstract
AbstractObjectiveEating expectancies (EE) are the anticipation of various benefits or detriments from eating, with mood regulation being a salient type of EE associated with eating disorders. This study examined the convergent and predictive validity of ecological momentary assessment (EMA) mood regulation EE items, including mood improvement and mood worsening EE.MethodsThirty women with binge‐eating pathology completed a 14‐day EMA protocol, which included measures of mood regulation EE, affect, appetite, appearance‐ and body‐related factors and disordered‐eating behaviours.ResultsGreater within‐subjects hunger and lower within‐subjects positive affect and fullness were related to elevated mood improvement EE. Higher within‐subjects appearance concerns, fullness, body social comparisons and thinness pressure were associated with higher mood worsening EE. Greater within‐subjects mood worsening EE predicted greater likelihood of vomiting at the subsequent time point, but there were no within‐subjects associations between mood improvement EE and behaviours. Yet, greater between‐subjects mood worsening EE were associated with more restraint/restriction and binge eating, and greater between‐subjects mood improvement EE were associated with more binge eating.ConclusionsFindings support the convergent validity of EMA mood regulation EE items. There was limited predictive validity evidence, suggesting complexities in how mood regulation EE predict behaviour in daily life.
