Emotion differentiation mediates the association between emotion regulation difficulties and caloric intake

摘要

Emotion differentiation is the ability to identify and label emotional experiences into discrete categories. The present study examined the influence of emotion regulation difficulties, emotion differentiation, and emotional state-specifically sad versus positive mood-on caloric intake in a laboratory setting. Undergraduate participants completed a series of questionnaires, including measures of emotion regulation difficulties and emotion differentiation, and then underwent a randomly assigned sad or positive mood induction. Afterwards, they participated in a taste test. Food was counted before and after the taste test to determine total caloric intake. Results showed that negative emotion differentiation was significantly inversely associated with overall caloric intake, such that low negative emotion differentiators ate more regardless of mood induction group. Positive emotion differentiation was not associated with caloric intake. Additional analysis found that negative emotion differentiation mediated the relation between emotion regulation difficulties and caloric intake. An alternative model found that emotion regulation difficulties did not mediate the relation between negative emotion differentiation and caloric intake. Our results suggest that reducing caloric intake among individuals with emotion regulation difficulties may involve incorporating strategies to specifically target the ability to differentiate between emotions.
