It also provided support for a bifactor model corresponding to the risk and psychological scales identified by Clausen and colleagues ( Clausen et al., 2011).

A recent investigation of the EDI-3 at the item, scale, and composite levels with an American clinical sample ( Brookings et al., 2020) provided confirmatory factor analyses that supported the 12 content scales described in the 2004 manual ( Garner, 2004). Specifically, the best-fitting models were: (a) a first-order model with correlated factors corresponding to the 12 scales and (b) a second-order model with two global factors: Eating Disorder Risk and Psychological Disturbance ( Clausen et al., 2011). An item confirmatory factor analysis of the EDI-3 for adult Danish patients and non-patient controls was supportive of its purported factor structure. 117) but notes that questions remain about the EDI-3 factor structure. One reviewer ( Cumella, 2006) has praized its “… superior section on test interpretation” (p. Like its predecessors, the EDI-3 has received generally favorable reviews. Six composite scales and three response style indicators were also added ( Table 3). The analysis yielded item clusters largely conforming to the EDI-2 scale structure but changed the scale assignment for some items, included a 12th scale, and expanded the item scores from four to five points (now 0–4). The EDI-3 validation retained the 91 EDI-2 items and examined the relationships among items by applying exploratory factor analysis (EFA) to normative and eating disorder samples. A subsequent revision (EDI-3) was guided by the evolution of theoretical models in the field since the original measure was introduced ( Garner, 2004). The first revision, the EDI-2 ( Garner, 1991a), added 27 items and increased the number of scales to 11. The original EDI was comprised of 64 self-report items requiring responses on a six-point scale ranging from “Never” to “Always.” Item scores were then collapsed to a four-point scale (0–3) and the items assigned to eight non-overlapping scales that assessed individual differences in eating disorder risk (three scales) and psychological features (five scales). Over time, the EDI has gained popularity among eating disorder clinicians and researchers and has been revised twice. The EDI generates psychological profiles useful for case conceptualization and treatment planning for those with confirmed or suspected eating disorder diagnoses ( Garner et al., 1983 Garner, 2004) in contrast to the EDE-Q and the EAT-26 that are limited to measuring specific eating disorder symptoms. The EDI is a standardized, multiscale instrument designed to measure psychological traits or symptom clusters relevant to the development and maintenance of eating disorders.

In addition, the EDI-3 contains the EDI Symptom Checklist (EDI-SC), which can be used singularly. 104 The EDI-3 takes approximately 20 min to complete and is composed of 11 subscales: drive for thinness, bulimia, body dissatisfaction, ineffectiveness, perfectionism, interpersonal distrust, interoceptive awareness, maturity fears, asceticism, impulse regulation, and social insecurity. The EDI-3 is a 91-item, self-report, Likert scale measure developed to assess for the psychologic and behavioral symptoms of various EDs.
