Objective: This study tested the association between food insecurity and eating disorder (ED) pathology, including probable ED diagnosis, among two cohorts of university students before and during the beginning of the COVID-19 pandemic.

Method: Students (n = 579) from a large Midwestern American university completed self-report questionnaires assessing frequency of ED behaviors, ED-related impairment, and individual food insecurity as measured by the Eating Disorder Diagnostic Scale 5, Clinical Impairment Assessment, and Radimer/Cornell, respectively. Chi-square tests and MANOVA with post-hoc corrections were conducted to compare demographic characteristics, ED pathology, and probable ED diagnosis prevalence between students with and without individual food insecurity.

Results: Partially supporting hypotheses, MANOVA indicated significantly greater frequency of objective binge eating, compensatory fasting, and ED-related impairment for students with food insecurity compared with individuals without food insecurity. Chi-squared tests showed higher prevalence of ED diagnoses among individuals with food insecurity compared with those without food security (47.6 vs. 31.1%, respectively, pā€‰<ā€‰.01, NNT = 6.06), specifically bulimia nervosa and other specified feeding and eating disorder. There were no differences in food insecurity before or during the beginning of the COVID-19 pandemic.

Discussion: Consistent with prior literature, food insecurity was associated with elevated ED psychopathology in this sample. Findings emphasize the importance of proper ED screening for college students vulnerable to food insecurity and EDs.

Development and initial validation of the Eating Pathology Symptoms Inventory-Clinician-Rated Version (EPSI-CRV).

Proper assessment and diagnosis of eating disorders (EDs) are critical to determine to whom prevention and treatment efforts should be targeted, the extent to which treatment is working, and when an individual has recovered. Although existing ED diagnostic interviews have numerous strengths, they also have certain limitations, including poor internal consistency, low discriminant validity, and poor factor-structure replicability. The purpose of the current study was to address problems of past ED diagnostic interviews through the creation of a new clinician-rated interview-the Eating Pathology Symptoms Inventory-Clinician-Rated Version (EPSI-CRV). The EPSI-CRV was designed to measure dimensional constructs assessed in the self-report version of the EPSI and generate current Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013) diagnoses. Participants were community-recruited adults with a DSM-5 ED (N = 257). Participants completed self-report and interview-based measures of eating, mood, and anxiety disorders and self-report measures of psychiatric impairment. The EPSI-CRV demonstrated evidence for interrater reliability, convergent and discriminant validity, and a good-fitting factor structure. EPSI-CRV dimensions showed concurrent validity for distinguishing among ED diagnoses. Baseline EPSI-CRV dimensions significantly predicted psychiatric impairment at baseline but not at 1-year follow-up. Although some scales had lower internal consistency than ideal, internal consistency values were similar to those of other established diagnostic measures. The EPSI-CRV appears to represent a promising new interview that can be used across a variety of clinical and research settings.
