Psychometric Properties of the Eating Disorder Examination Questionnaire (EDE-Q) and Norms for Rural and Urban Adolescent Males and Females in Mexico

Abstract

AimsTo contribute new evidence to the controversy about the factor structure of the Eating Disorder Examination Questionnaire (EDE-Q) and to provide, for the first time, norms based on a large adolescent Mexican community sample, regarding sex and area of residence (urban/rural). MethodsA total of 2928 schoolchildren (1544 females and 1384 males) aged 11-18 were assessed with the EDE-Q and other disordered eating questionnaire measures.ResultsConfirmatory factor analysis of the attitudinal items of the EDE-Q did not support the four theorized subscales, and a two-factor solution, Restraint and Eating-Shape-Weight concern, showed better fit than the other models examined (RMSEA = .054); measurement invariance for this two-factor model across sex and area of residence was found. Satisfactory internal consistency (ω ≥ .80) and two-week test-retest reliability (ICCa ≥ .84; κ ≥ .56), and evidence for convergent validity with external measures was obtained. The highest attitudinal EDE-Q scores were found for urban females and the lowest scores were found for rural males, whereas the occurrence of key eating disorder behavioural features and compensatory behaviours was similar in both areas of residence. ConclusionsThis study reveals satisfactory psychometric properties and provides population norms of the EDE-Q, which may help clinicians and researchers to interpret the EDE-Q scores of adolescents from urban and rural areas in Mexico.

Eating Disorder Examination–Questionnaire (EDE–Q): Norms for Clinical Sample of Female Adolescents with Anorexia Nervosa

“…Female adolescents in this study reported higher mean EDE-Q scores on the subscales and global scale compared to previously published studies of healthy female adolescents (Carter et al, 2001; Machado et al, 2014; Mond et al, 2014; Penelo et al, 2013). In other words, female adolescents in the present study reported greater severity of eating disorder psychopathology compared to healthy female adolescents.…”

“…Normative EDE-Q data are available for healthy adolescent girls in the United Kingdom (Carter, Stewart, & Fairburn, 2001) and Portugal (Machado et al, 2014), and healthy adolescent boys and girls in Australia (Mond et al, 2014), Malaysia (Musa et al, 2016), and Mexico (Penelo, Negrete, Portell, & Raich, 2013). One Swedish study (Mantilla & Birgegard, 2016) reported norms on clinical and healthy adolescents using a 14-day time frame version of the EDE-Q, which had been specifically modified for adolescents (Carter et al, 2001).…”

Confirmatory factor analysis and measurement invariance of the eating disorders examination‐questionnaire across four male samples in Argentina

“…In this regard, evidence of invariance across gender has been described for the two-factor model among Mexican teenagers (Penelo et al, 2013). In this regard, evidence of invariance across gender has been described for the two-factor model among Mexican teenagers (Penelo et al, 2013).…”

“…While one study noted support for the original four-factor model among university students in Spain (Penelo, Villarroel, Portell, & Raich, 2012), another study has rejected the four-factor model among US college athletes (Darcy, Hardy, Crosby, Lock, & Peebles, 2013) and among teenagers in Mexico (Penelo, Negrete, Portell, & Raich, 2013).

Validación Mexicana De La Escala De Actitudes Masculinas Sobre El Cuerpo en Estudiantes Universitarios Varones

“…En éste estudio se utilizó la versión adaptada y validada en población española por Peláez, Labrador & Raich (2012), con consistencia interna aceptable para las cuatro escalas (α≥.74). En población mexicana se obtuvo una consistencia interna satisfactoria (α≥.80) (Penelo, Negrete, Portell, & Raich, 2013). A mayor puntuación, mayor gravedad en la patología alimentaria.…”
