The Emotional Eating Scale Adapted for Children and Adolescents (EES-C): development and preliminary validation of a...

The 25-item Emotional Eating Scale for children and adolescents (EES-C) is a psychometrically sound instrument that measures the extent to which youth eat in response to negative emotions. Nonetheless, questionnaire length may serve as a barrier to routine administration in clinical and school settings, and diminish the likelihood of the measure being utilized in population-wide health studies. The present study reported on the development and preliminary validation of a short-form of EES-C using data from two previously published studies. Guidelines for the development of short-form questionnaires, content and factor analyses, and other indices including standard deviations, item-total correlations, inter-item correlations, Cronbach's alpha without the item, and floor/ceiling effects were examined to develop a 10-item EES-C Short-Form. The EES-C Short-Form demonstrated acceptable psychometric properties, including good internal consistency reliability (alpha = .87) and a high degree of overlapping variance with the original EES-C Total Score and Subscale Scores (r = .71 to .96). The EES-C Short-Form also manifested a unidimensional factor structure in an Exploratory Factor Analysis, supporting construct validity. Taken together, results from the current study provide preliminary evidence of the reliability and validity of a 10-item EES-C Short-Form.
