Adaptation and validation of the Eating Disorder Examination-Questionnaire in English among urban Indian adolescents

Objective Eating pathology is a salient issue in India, with clinical features reported among adults and adolescents. However, there are currently no validated measures of disordered eating in the Indian context. The present study therefore aimed to validate a culturally appropriate English language version of the Eating Disorder Examination Questionnaire (EDE-Q), a widely used measure, among adolescents in India. Method We adapted and examined the factor structure, reliability, and construct validity of the EDE-Q among an urban sample of 1,413 Indian adolescents (mean age = 13 years; 45% girls). Results In contrast to the original four-factor model, exploratory factor analysis identified a two-factor solution for girls and boys, which was verified by confirmatory factor analysis; a "Preoccupation and Control" subscale and a "Weight and Shape Concerns" subscale. The total scale comprised 15 items for girls and 18 items for boys. Test-retest reliability and internal consistency were satisfactory for the girls' and boys' scales (Cronbach's alpha = .91 for both) and their comprising subscales (alpha s >= .80). Concurrent validity was established through medium-high significant correlations with measures of body image and internalization of appearance ideals. Combining items common to both versions of the scale led to a psychometrically acceptable model which was largely invariant across both genders, thus facilitating gendered comparison. Discussion Findings indicate the reliability and validity of the EDE-Q among English-speaking urban Indian adolescents. This will facilitate further research examining the prevalence and nature of eating pathology among adolescents in India.
