Enhanced cognitive-behavioral therapy (CBT-E) is one of the primary evidence-based treatments for adults with eating disorders (EDs). However, up to 50% of individuals do not respond to CBT-E, likely because of the high heterogeneity present even within similar diagnoses. This high heterogeneity, especially in regard to presenting pathology, makes it difficult to develop a treatment based "on averages" and for clinicians to accurately pinpoint which symptoms should be targeted in treatment. As such, new models based at both the group, and individual level, are needed to more accurately refine targets for personalized evidence-based treatments that can lead to full remission. The current study (Expected N = 120 anorexia nervosa, atypical anorexia nervosa, and bulimia nervosa) will build both group and individual longitudinal models of ED behaviors, cognitions, affect, and physiology. We will collect data for 30 days utilizing a mobile application to assess behaviors, cognition, and affect and a sensor wristband that assesses physiology (heart rate, acceleration). We will also collect outcome data at 1-and 6-month follow-ups to assess ED outcomes and remission status. These data will allow for identification of "on average" and "individual" targets that maintain ED pathology and test if these targets predict outcomes, including ED remission.

“…For these 22 items, a four-factor structure has been proposed representing eating restraint, eating concern, weight concern and shape concern. However, this factor structure could not be replicated in the literature (Heiss, Boswell, & Hormes, 2018;Rand-Giovannetti, Cicero, Mond, & Latner, 2020). Therefore, we only used the total score in the current analyses.…”

Objective: Inpatient treatment effectively increases body weight and decreases eating disorder symptoms in adolescents with anorexia nervosa (AN). However, there is a high risk of relapse within the first year after discharge, which calls for investigating long-term treatment success and its moderators. Method: Female adolescent inpatients with AN (N ¼ 142) were assessed, of which 85% participated at 1-year follow-up. Dependent variables were body mass index percentiles, eating disorder symptoms, depressive symptoms, compulsive exercise and life satisfaction. Results: On average, body weight increased and eating disorder symptoms and depressive symptoms decreased from admission to discharge and remained stable at follow-up. Compulsive exercise decreased and life satisfaction increased from admission to discharge and even improved further at follow-up. Age, duration of illness, previous inpatient treatments, length of stay and readmission after discharge moderated changes in several outcome variables. Conclusions: This study confirms the high effectiveness of inpatient treatment for adolescents with AN and demonstrates that treatment effects remain stable or even improve further within the first year after discharge. However, subgroups of patients (e.g., those with an older age, longer duration of illness, and previous inpatient treatments) require special attention during inpatient treatment and aftercare to prevent relapse. K E Y W O R D S adolescents, anorexia nervosa, inpatient treatment, moderators, treatment outcome 1 | INTRODUCTION AND AIMS Anorexia nervosa (AN) is an eating disorder marked by restriction of energy intake-which leads to a significantly low body weight-intense fear of gaining weight and body image disturbance (American Psychiatric Association, 2013). Although AN can occur at any age, the highest incidence rates can be found in adolescence (Zipfel, Giel,

“…The EDE‐Q can be used to produce a summary of both attitudinal (e.g., concerns about weight) and behavioral (e.g., binge eating) symptoms and the measure has been used in clinical and non‐clinical populations (e.g., see Carey et al, 2019, for a recent review). Although the EDE‐Q has demonstrated acceptable reliability and validity, the originally proposed factor structure for the attitudinal items has “proven difficult to replicate” (Heiss, Boswell, & Hormes, 2018, p. 419; see also Carey et al, 2019). Furthermore, the 28‐item EDE‐Q may be of limited use in epidemiology research and clinical settings in which response burden is often a concern (Gideon et al, 2016; Kliem et al, 2016).…”

Objective: Several recent studies have examined the psychometric properties of brief measures of eating disorder attitudes based on the Eating Disorder Examination Questionnaire (EDE-Q). A seven-item version (the EDE-Q7) has been proposed but, as yet, has only been investigated by looking at the items when presented as part of the longer EDE-Q (i.e., as a nested version). The current study presented the EDE-Q7 as a standalone instrument and examined factor structure fit and measurement invariance across male and female genders. Methods: University students (244 women; 155 men; 1 did not identify with either gender) completed questionnaires as part of two independent studies. All individuals completed the EDE-Q7 and measures of eating disorder behaviors. In a mixed-gender subsample (n = 286), measures of depression and eating disorder-specific quality of life were also included. Confirmatory factor analysis of the EDE-Q7 was conducted on males and females independently, in addition to estimates of internal consistency reliability and validity. Measurement invariance was assessed through multigroup confirmatory factor analysis. Results: The EDE-Q7 demonstrated good internal consistency and findings supported measurement invariance by gender. In a mixed-gender subsample, the measure showed positive associations with depression and both eating disorder behaviors and eating disorder-specific quality of life. Discussion: The present study adds to the literature supporting the psychometric properties of the EDE-Q7, extending this to use of the questionnaire as a standalone instrument. Measurement invariance suggests that the measure may be appropriate for college-age men and women, although future studies should establish psychometric properties more fully.

Confirmatory factor analysis of the Eating Disorder Examination‐Questionnaire: A comparison of five factor solutions across vegan and omnivore participants

Abstract: Our data confirm difficulties in replicating the proposed factor structure of the EDE-Q, including in vegans. More research is needed to determine the suitability of the EDE-Q for quantifying eating behaviors, including in those abstaining from animal products.
