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

Abstract

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 factorstructure 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 ϭ 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.

Public Significance StatementIt is important to properly assess and diagnose eating disorders (EDs) to determine to whom prevention and treatment efforts should be targeted, the extent to which treatment is working, and when an individual has recovered. However, most ED diagnostic assessments have problems that limit their usefulness in clinical practice and research. Our results showed that our new diagnostic assessment-the Eating Pathology Symptoms Inventory-Clinician-Rated Version (EPSI-CRV)performed as well as, or better than, past ED diagnostic assessments. Thus, the EPSI-CRV represents a promising new diagnostic tool for use by clinicians and researchers.

Validity and utility of Hierarchical Taxonomy of Psychopathology (HiTOP): III. Emotional dysfunction superspectrum

“…The Interview for Mood and Anxiety Symptoms targets dimensions similar to the IDAS-II, but with an interview format to capture the strengths of clinician-based assessment 80,471,490 . These instruments can be supplemented with the self-rated 90 and clinician-rated 491 versions of the Eating Pathology Symptoms Inventory, which provide comprehensive assessment of eating disorder symptoms. Widely used measures of sexual functioning are problematic 492 , indicating a need for better assessment.…”

Hyper‐palatable food consumption during binge‐eating episodes: A comparison of intake during binge eating and restricting

“…Participants in the parent study were recruited from two midwestern universities and surrounding communities by email, flyers, and community advertisements between 2012 and 2018. Inclusion criteria for the current study were (1) diagnosis of sub‐threshold or full‐threshold BN, and (2) endorsement of both binge‐eating and restricting episodes as measured in the Eating Pathology Symptoms Inventory‐Clinician Rated Version (EPSI‐CRV; Forbush et al, 2020). Sub‐ and full‐threshold diagnoses were included because research has shown that they do not differ in demographic features, comorbid psychopathology, or clinical impairment (Chapa, Bohrer, & Forbush, 2018; Fairweather‐Schmidt & Wade, 2014; Johnson, Forbush, Swanson, & Christensen, 2021; Wade & O'Shea, 2015).…”

“…The EPSI-CRV (Forbush et al, 2020) is a semi-structured interview based on the Eating Pathology Symptoms Inventory (EPSI) self-report measure, which assesses eight dimensions of eating pathology (Forbush et al, 2013). The EPSI-CRV assesses ED psychopathology over the past 3 months via the following modules: body dissatisfaction, objective binge eating, cognitive restraint, excessive exercise, restricting, purging, muscle building, and negative attitudes towards obesity.…”

“…The EPSI-CRV includes additional modules (low weight, overvaluation of weight and shape, and fear of weight gain) to determine ED diagnosis based on the DSM-5 criteria. The EPSI-CRV demonstrated a high degree of interrater reliability for binge eating and restricting modules (intraclass correlation coefficients 0.97 and 0.99, respectively; Forbush et al, 2020). OBE and restricting episodes were determined by consensus among a group of trained graduate students and a doctoral-level clinical psychologist during a weekly group consensus meeting.…”

Are the Criterion B binge‐eating symptoms interchangeable in understanding binge‐eating severity? An item response theory analysis

“…Participants completed the Eating Pathology Symptoms Inventory‐Clinician Rated Version (EPSI‐CRV), a semi‐structured interview that assesses ED psychopathology and behaviors over the previous 3 months (EPSI‐CRV; Forbush et al, 2020). The EPSI‐CRV collects information necessary to make current ED diagnoses.…”
