The role of eating expectancies and eating motives in the association between mood and loss-of-control eating: a national sample daily diary study.

Loss-of-control eating (LOCE, the subjective inability to refrain from eating or cease eating), is highly mood-driven. Mood-related eating motives and eating expectancies have been identified as contributors to binge eating. However, little is known about how these factors relate to LOCE, much less their relationship with daily-level LOCE.

United States adults (n = 109) reporting recent LOCE participated in a ten-day diary study, completing two surveys per day regarding eating behaviors, mood, and motives. Data were analyzed at the within- and between-subject levels utilizing a Bayesian approach to examine pathways from mood to LOCE, mediated by eating motives and accounting for a moderating impact of baseline eating expectancies on the path leg between mood and motives.
