Construct validity of the Levels of Emotional Awareness Scale among women high in eating disorder symptoms: a cross-sectional study.

Abstract

The Levels of Emotional Awareness Scale (LEAS), a measure of the ability to identify and describe one's own and others' emotions, may complement work with women with disordered eating symptoms. The study purpose was to (a) examine differences in hand (LEAS) versus computerized (e-LEAS) scoring methods and (b) examine the e-LEAS' psychometric properties, including convergent and discriminant validity, among women endorsing eating disorder symptoms. Forty women (ages 18-21) scoring high on a self-report measure of disordered eating symptoms completed the LEAS and measures of convergent validity including a self-report measure of alexithymia (the perceived ability to identify and describe one's own emotions) and a measure of facial affect recognition as well as discriminant validity, including affect and facial memory. Inter-rater reliability was assessed via a two-way mixed effects model and correlations between the LEAS and the study constructs were examined. Computerized scoring (e-LEAS) offered benefits over hand scoring and correlations between LEAS and e-LEAS were statistically significant. Better total emotional awareness scores on the e-LEAS were significantly associated with more perceived difficulty identifying and describing emotions. Better total emotional awareness scores were also significantly associated with better facial memory and greater depression scores. The e-LEAS showed weak associations with facial affect recognition. The e-LEAS offers practical advantages over the LEAS in the assessment of emotional awareness among women endorsing eating disorder symptoms. Results suggest that the e-LEAS measures the ability to describe emotional experiences in oneself and others, but not facial affect recognition.
