| Abstract: | The purpose of the studies presented was to develop and examine the psychometric properties of the Eating Habits Questionnaire (EHQ). The author designed the 21-item self-report inventory to assess cognitions, behaviors, and feelings related to an extreme focus on healthy eating as a preliminary step in researching an alleged syndrome that has been labeled "orthorexia nervosa", defined as a pathological fixation on healthy eating. Study 1 examined the factor structure of the EHQ and refined the instrument with exploratory factor analysis. A 3-factor solution was preferred, with subscales labeled: knowledge of healthy eating, problems associated with healthy eating, and feeling positively about healthy eating. In the Study 1 sample (n = 174) the subscales displayed good internal consistency (.87 to .91) and test-retest reliability (.74 to .87). Study 2 examined the fit of the 3-factor model in a new sample (n = 213) with confirmatory factor analysis. Poor initial fit became adequate after eliminating poorly fitting items. Internal consistency (.82 to .90) and test-retest reliability (.72 to .81) of the subscales remained good in the Study 2 sample. Examination of correlations between the EHQ subscales and a variety of other measures provided preliminary evidence for both convergent and discriminant validity in the Study 2 sample. As expected, the EHQ subscales correlated more highly with measures of eating related pathology than with measures of general pathology, personality characteristics, or social desirability. |
