“…The EFA and CFA with the EDE-Q items revealed a 12-item, 4-factor structure that did not replicate the original EDE-Q subscales. In fact, the four extracted factors were more comparable to those found by Peterson et al (19) with data from a community sample of women with bulimic symptoms. Both the current authors and Peterson et al (19) identified a similar body dissatisfaction/discomfort factor (which consisted of both Shape Concern and Weight Concern items), while both studies found that overvaluation of shape and weight loaded separately rather than with appearance concernrelated items.…”

Objective-Despite increasing use of the Eating Disorder Examination-Questionnaire (EDE-Q) in bariatric surgery patients, little is known about the utility and psychometric performance of this self-report measure in this clinical group. The primary purpose of the current study was to evaluate the factor structure and construct validity of the EDE-Q in a large series of bariatric surgery candidates.Methods and Procedures-Participants were 337 obese bariatric surgery candidates. Participants completed the EDE-Q and a battery of behavioral and psychological measures.Results-Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) produced a 12-item, 4-factor structure of the EDE-Q. The four factors, interpreted as Dietary Restraint, Eating Disturbance, Appearance Concerns, and Shape/Weight Overvaluation, were found to be internally consistent and converged with other relevant measures of psychopathology.Discussion-Factor analysis of the EDE-Q in bariatric surgery candidates did not replicate the original subscales but revealed an alternative factor structure. Future research must further evaluate the psychometric properties, including the factor structure, of the EDE-Q in this and other diverse populations and consider means of improving this measure's ability to best assess eatingrelated pathology in bariatric surgery patients.

“…Body dissatisfaction was operationalized by combining the Weight Concern and Shape Concern subscales (12 items total) to capture multiple aspects of body dissatisfaction. Furthermore, factor analytic work supports the items from these two subscales generally loading on one factor (Peterson et al, 2007). The EDE-Q subscales have good internal consistency (α=.78-.…”

The current study tested a psychosocial interactive model of perfectionism, self-efficacy, and weight/ shape concern within a sample of women with clinically significant bulimic symptoms, examining how different dimensions of perfectionism operated in the model. Individuals with bulimia nervosa (full diagnostic criteria or subthreshold) completed measures of bulimic symptoms, multidimensional perfectionism, self-efficacy, and weight/shape concern. Among those who were actively binge eating (n = 180), weight/shape concern was associated with binge eating frequency in the context of high perfectionism (either maladaptive or adaptive) and low self-efficacy. Among those who were actively vomiting (n = 169), weight/shape concern was associated with vomiting frequency only in the context of high adaptive perfectionism and low self-efficacy. These findings provide support for the value of this psychosocial interactive model among actively binge eating and purging samples and for the importance of considering different dimensions of perfectionism in research and treatment related to bulimia nervosa.

“…Respondants rate 22 items using a 7-point frequency (0 = never; 6 = daily) and severity (0 = not at all; 6 = markedly) scale. The internal reliability of the measure is high (Cronbach's alpha = 0.90; see Peterson et al, 2007). The EDE-Q is widely with adults with eating disorders and has demonstrated validity in the assessment of adolescents with eating disorders (Binford and LeGrange, 2005).…”

Direct and indirect forms of non-suicidal self-injury: Evidence for a distinction

Non-suicidal self-injury (NSSI) involves deliberate acts (such as cutting) that directly damage the body but occur without suicidal intent. However, other non-suicidal behaviors that involve people mistreating or abusing themselves but that do not deliberately and directly damage bodily tissue may have much in common with NSSI. Such 'indirect' methods of self-injury might include involvement in abusive relationships, substance abuse, risky or reckless behavior, or eating disordered behavior. Using a community sample (N=156) we compared individuals engaging in NSSI (n=50), indirect (non-suicidal) self-injurers (n=38), and healthy controls (n=68) on a range of clinical and personality characteristics. As predicted, non-suicidal selfinjurers and indirect self-injurers showed more pathology than healthy controls on all measures.Comparisons of the NSSI and the Indirect self-injury groups revealed no significant differences on measures of dissociation, aggression, impulsivity, self-esteem, negative temperament, depressive symptoms, and borderline personality disorder. However, compared to people who engaged only in indirect forms of self-injury, those who engaged in NSSI were more self-critical, had higher scores on a measure of suicide proneness, and had a history of more suicide attempts.The findings suggest that NSSI and indirect self-injury are best viewed as separate and distinct clinical phenomena.Key Words = DSM-5, non-suicidal self-injury (NSSI), deliberate self-harm, suicide, borderline personality disorder, self-criticism.NSSI and Indirect Self--Injury 3 3

Psychometric properties of the eating disorder examination‐questionnaire: Factor structure and internal consistency

Abstract: The results of this study provide support for the internal consistency of the EDE-Q and indicate a need for further examination of the factor structure of this instrument.
