Abstract:Objective: The main aim was to perform a systematic literature review of studies investigating the factor structure of the Eating Disorder Examination-Questionnaire (EDE-Q), a widely used measure of eating pathology. Secondary aims were to summarize the quality of reporting of latent variable (factor) analyses in these studies and review support for different factor solutions.Method: Literature was identified through Scopus, Medline, PsycInfo, and ProQuest databases published up to February 23, 2022 and outrea… Show more
“…The EDE-Q has been shown to have good internal consistency and other psychometric properties [ 55 ]. Yet, a short version known as the EDE-Q7 [ 56 , 57 ] is described as offering more robust psychometric properties than the original version [ 58 ].…”
Background
Psychotic disorders and eating disorders are complex mental illnesses associated with increased mortality and functional impairment. This study aimed to investigate the co-occurrence and relationships between eating disorders and psychotic disorders and assess the mediation effect of mood instability.
Methods
This study used data from the Adult Psychiatric Morbidity Survey (APMS) 2014, a general population-based survey in England. Participants (total N = 7546, female N = 4488, male N = 3058, mean age = 52.3 years) were categorised based on psychotic disorder status into the groups of probable psychosis, diagnosed psychosis, and healthy controls without psychosis. The dependent variable of this study was the presence or absence of an eating disorder, with mood instability as the mediator. Logistic regression and mediation analyses were conducted to assess the relationships between these variables.
Results
Both probable and diagnosed psychoses were significantly related to the presence of an eating disorder, and mood instability was found to be a mediating variable with moderate effect.
Conclusion
The present study demonstrates a significant relationship between eating disorders and psychotic disorders in the English general population, indicating higher levels of co-occurrence between these two groups of disorders than when compared with healthy controls. The findings also suggest the relationship between eating and psychotic disorders is mediated, to an extent, by the presence of mood instability traits. Future research could extend the present study’s findings through assessing whether specific eating disorders are more significantly related to psychotic disorders than others.

“…Gender differences in ED pathology may play a central role in lowered recognition and underrepresentation of men in ED research, as standard assessments were developed based on ED presentation in adolescents and young women [ 17 , 18 ]. Consequently, there have already been initial attempts to develop men-specific assessment instruments [ 19 – 21 ] as well as to validate existing ED assessments in men [ 22 – 24 ]. For example, the widely used Eating Disorder Examination-Questionnaire (EDE-Q; [ 25 ]), designed to capture the variation and severity in eating-related psychopathology [ 26 ], is based on common cognitive behavioral models of ED.…”

“…These and similar findings question the validity of using the EDE-Q subscales for measuring ED pathology in men. Indeed, several studies have shown difficulties reproducing the original EDE-Q factor structure, including in cohorts of men [ 24 , 33 ]. This indicates that the original factor model may not be sensitive to different ED manifestations in adult men [ 23 , 24 ].…”

“…Indeed, several studies have shown difficulties reproducing the original EDE-Q factor structure, including in cohorts of men [ 24 , 33 ]. This indicates that the original factor model may not be sensitive to different ED manifestations in adult men [ 23 , 24 ]. For example, Klimek et al [ 34 ] showed that in men who identify as gay, bisexual, or otherwise non-heterosexual ( n = 479), the original four-factor solution could not be applied, similar to a male Argentine sample consisting of university students and athletes ( n = 986; [ 35 ]).…”

“…Thus far, however, previous investigations on EDE-Q factor structures in men have been limited to non-clinical settings [ 36 , 37 ], severely limiting conclusions about the EDE-Q’s factorial validity among men with diagnosed ED. For example, it is currently unknown whether and which subscale scores should be reported for men with ED, or which subscale could be used to compare men with ED to other samples, or for tracking treatment response [ 24 ]. Hence, analysis and, if necessary, adaptation of the factor structure to specific patient groups are elementary for valid ED assessment.…”
Background
Previous investigations on the Eating Disorder Examination-Questionnaire (EDE-Q) factor structures in men have been restricted to non-clinical settings, limiting conclusions about the factorial validity in men with eating disorders (ED). This study aimed to examine the factor structure of the German EDE-Q in a clinical group of adult men with diagnosed ED.
Methods
ED symptoms were assessed using the validated German version of the EDE-Q. Exploratory factor analysis (EFA) using principal-axis factoring based on polychoric correlations was conducted for the full sample (N = 188) using Varimax-Rotation with Kaiser-Normalization.
Results
Horn’s parallel analysis suggested a five-factor solution with an explained variance of 68%. The EFA factors were labeled “Restraint” (items 1, 3–6), “Body Dissatisfaction” (items 25–28), “Weight Concern” (items 10–12, 20), “Preoccupation” (items 7 and 8), and “Importance” (items 22 and 23). Items 2, 9, 19, 21, and 24 were excluded due to low communalities.
Conclusions
Factors associated with body concerns and body dissatisfaction in adult men with ED are not fully represented in the EDE-Q. This could be due to differences in body ideals in men, e.g., the underestimation of the role of concerns about musculature. Consequently, it may be useful to apply the 17-item five-factor structure of the EDE-Q presented here to adult men with diagnosed ED.
The role of therapeutic alliance within psychological treatments for eating disorders (EDs), including those delivered remotely, is well established. However, few studies have investigated alliance in guided self‐help, a widely recommended first‐line treatment for EDs characterised by regular binge eating. Using data from a randomised controlled trial, the current study examined both facilitator and patient assessments of alliance within e‐mail‐assisted and face‐to‐face guided self‐help and looked at associations between alliance, ED symptoms and ED‐related impairment. One hundred thirteen patients and 11 facilitators completed measures of alliance during and following a course of guided self‐help. Whilst ratings were reliable across patients and facilitators, alliance scores were higher both in the patient sample and in the face‐to‐face condition. Ratings of alliance showed no correlations with ED symptoms at post‐treatment, and early alliance was not significantly associated with outcome, which could inform how early symptom change is encouraged in guided self‐help.
