The Factor Structure and Psychometric Properties of the Greek Version of the Eating Disorders Examination Questionnaire (EDE-Q)

Abstract

This study investigates the latent structure and the psychometric characteristics of the attitudinal subscales of the Greek translation of the EDE-Q (G-EDE-Q) using two samples. The first sample consisted of 500 university female students and tested the latent structure of the G-EDE-Q. The second sample consisted of 164 female psychology students and examined the internal consistency as well as the concurrent, convergent, and discriminant validity of the G-EDE-Q. The results from confirmatory factor analysis (CFA) showed that a three-factor solution fit the data better than the other models examined, providing evidence to contradict the originally proposed structure of the instrument. The results support both, the internal consistency as well as the concurrent, convergent, and discriminant validity of the G-EDE-Q global scale and its subscales. The discussion focuses on the critical review of previous statistical procedures employed and the clinical and research implications of the present findings.

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

“…The pattern found was similar to that for Spanish young adult college students [18,20] and Turkish primary and high school students [21], with higher correlation values for females than males. As in previous research, correlation coefficients with EAT scores were in the range of .20-.60 [9,21,23] and the lowest values involved Restraint [13,14,21] and EDI-2 bulimia scores [18,20,24]. We also obtained satisfactory reliability indices for the EDE-Q scores, similar to or slightly higher than those in previous studies, both in terms of internal consistency [4,7,9-11,13-21] and two-week temporal stability [15,19,21,23].…”

“…CFA has also supported this 3-factor model [6,8,9], despite the high correlation values of .90 [5] and .84 [6] found between Eating concern and Shape-Weight concern may suggest only a distinct Restraint subscale vs. "concern" items (2-factor model) [7] or even the use of the EDE-Q global summary score as a unitary dimensional construct (1-factor model) [4,7] (also Pennings & Wojciechowski, as cited in Allen et al) [5]. …”

“…However, clinicians and researchers are often in need of more cost-effective assessment methods. Normative data have been published from various settings in England, USA, Australia, Germany, Mexico, Greece, Turkey, Sweden and Norway (Carter, Aime, & Mills, 2001;Giovazolias, Tsaousis, & Vallianatou, 2013;Hilbert, de Zwaan, & Braehler, 2012;Luce, Crowther, & Pole, 2008;Mond, Hay, Rodgers, & Owen, 2006;Penelo, Negrete, Portell, & Raich, 2013;Welch, Birgegard, Parling, & Ghaderi, 2011;Yucel et al, 2011). The psychometric properties of this instrument are well established (Berg, Peterson, Frazier, & Crow, 2011;Berg, Peterson, Frazier, & Crow, 2012) with regard to internal consistency (Peterson et al, 2007), temporal stability (Mond, Hay, Rodgers, Owen, & Beumont, 2004a;Reas, Grilo, & Masheb, 2006), convergent validity (Mond, Hay, Rodgers, Owen, & Beumont, 2004b;Reas, Wisting, Kapstad, & Lask, 2011) and sensitivity to change (Sysko, Walsh, & Fairburn, 2005).…”

“…Based on original and clinically derived recommendations from the EDE interview (Fairburn & Beglin, 1994), a mean global score of 4.0 has been used as a threshold of ED psychopathology in community studies of the EDE-Q (Giovazolias et al, 2013;Kelly, Cotter, & Mazzeo, 2012;Penelo et al, 2013). However, there is evidence from clinical settings showing that nearly half of patients diagnosed with an ED obtain a mean global score of less than 4.0 (Aardoom, Dingemans, Slof Op't Landt, & Van Furth, 2012;Welch et al, 2011).…”

The Patient’s Perspective: Exploring Factors that Contribute to Recovery from Eating Disorders

“…When appropriate, respondents are requested to provide a frequency count. In a recent study by Giovazolias et al [31], the validity of the Greek version of EDE-Q was investigated. The authors concluded that the results supported both the internal consistency, as well as the concurrent, convergent and discriminant validity of the EDE-Q global scale and its subscales.…”
