Within-day variability in negative affect moderates cue responsiveness in high-calorie snacking
This 2021 study investigated whether total negative affect per day and level of negative affect variability per day possess influence on the likelihood of the individual eating high-calorie snacks in the presence of snacking cues. The data was extracted from an ecological momentary assessment study which took food logs and tested their 60 participants for 14 days using known snack cues. As with previous studies, the chances of the subject consuming a snack increased when food was available, when others were eating, and when higher negative affect was experienced. These associations between snack consumption with food availability and presence of others eating were significantly moderated by negative affect variability. In other words, correlations between snack cues and high-calorie snacking were weaker on days of higher negative affect variability. However, negative affect levels did not moderate the relationship between cue and snacking. In conclusion, variability in negative affect can have an influence on the snacking cue-behavior interaction. A complex relationship is suggested here between negative affect and calorie-dense snacking, perhaps requiring clearer conceptualizations.
