Abstract

Objective: One of the most widely used assessment tools for disordered eating attitudes and behaviors, the Eating Disorder Examination Questionnaire (EDE-Q), has not yet been evaluated in Brazilian cisgender gay and bisexual men-an at-risk population given the extent of minority stressors in Brazilian culture. The present study aimed to assess the psychometric properties of the EDE-Q among Brazilian cisgender gay and bisexual adult men.

Method: The Brazilian EDE-Q was administered to a sample of 1409 gay and bisexual adult men, along with measures of self-objectification, body-ideal internalization, drive for muscularity, muscle dysmorphia symptoms, and body appreciation. The factor structure of the Brazilian EDE-Q was assessed using a two-step, split-sample exploratory (EFA; n = 704) and confirmatory factor analytic approach (CFA; n = 705). Additionally, convergent validity, internal consistency, and 2-week test-retest reliability were assessed.

Results: Findings from an EFA and CFA revealed a one-factor structure with 22 items and adequate internal consistency (ω = .92, 95% CI = [.91, .93]). Moreover, the scale demonstrated good 2-week test-retest reliability (ICC = .86, 95% CI = [.82, .88], p < .001). The EDE-Q scores showed positive associations with self-objectification, body-ideal internalization, muscle dysmorphia symptoms, and drive for muscularity, as well as a negative association with body appreciation.

Discussion: Results provide support for the use of the EDE-Q using a one-factor structure in Brazilian cisgender gay and bisexual adult men and give insights for future studies on eating disorders in sexual minorities in Latin America.

Public significance: The Eating Disorder Examination Questionnaire (EDE-Q) is one of the most widely used self-report measures of eating disorder symptoms. However, there is a lack of research on the validity and reliability of the EDE-Q in Latin American countries. This study evaluated the validity and reliability of the EDE-Q in Brazilian cisgender gay and bisexual adult men. Our findings give insights for future studies on eating disorders in sexual minorities in Latin America.

Keywords: Brazil; EDE-Q; Latin America; eating pathology; measurement; psychometrics; sexual and gender minorities.
