Objective. To examine psychometric properties and investigate factor structures of the Mandarin Chinese version of the Eating Disorder Inventory (C-EDI). Method. The Mandarin C-EDI and other self-administered questionnaires were completed by a group of female eating disorder (ED) patients (n = 551) and a group of female nursing students (n = 751). Internal consistency, and convergent and discriminant validities were evaluated. Exploratory and confirmatory factor analyses were conducted to examine the construct validity of the Mandarin C-EDI. Results. The Mandarin C-EDI had good internal consistency and convergent and discriminant validities. With a few exceptions, the original clinically derived eight EDI subscales were clearly identified and the factorial validity of the first-order eight-factor structure and the second-order two-factor structure showed an acceptable degree of fit to our empirical data in clinical patients. Discussion. The findings suggest that the Mandarin C-EDI is a valid tool for clinical use in Taiwan.

    ABSTRACT: Insofar as the factor structure of the Eating Disorders Inventory (EDI) among nonclinical participants is unclear (despite very wide use), the present study addressed the factor structure of five EDI subscales (Drive for Thinness, Bulimia, Perfectionism, Interpersonal Distrust, and Maturity Fears). Relatively large samples of non-patient women who participated in a cohort study of behavior and diet in 1982 (N = 617) and 1992 (N = 545) completed the five EDI subscales. Results are the first to clearly support the intended factor structure of the EDI among nonclinical participants.

    ABSTRACT: To develop a reliable and valid psychiatric self-rating scale for use in medical practice, the authors modified Derogatis' Symptom Check List-90-R (SCL-90-R) and designed a shorter form, named Brief Symptom Rating Scale (BSRS). The BSRS comprises 50 items, which best reflect the original ten symptom dimensions and three indices of psychopathology from the SCL-90-R. The BSRS has been proven in different populations to have an excellent split-half reliability as well as good internal structure according to factor analysis. In addition, BSRS scores are highly correlated with the parental form SCL-90-R among medical populations for each symptom dimension and the three indices. The rate of accurate classification for BSRS between psychiatric and nonpsychiatric cases was 75.8%, with a sensitivity of 66.7% and a specificity of 86.7% by discriminant analysis based on 10 dimensional scores obtained from 1,638 subjects, randomly selected from the Psychiatric Outpatient Clinic, the Family Medicine Clinic and nonpsychiatric medical inpatients. Therefore, the BSRS is a satisfactory global measure and case-finding screening instrument for psychopathology in both psychiatric and nonpsychiatric medical settings.

    ABSTRACT: To investigate the characteristics and prevalence of binge eating among overweight Taiwanese and to determine the effect of binge eating on outcome of weight loss treatment. One hundred and eighty-nine participants in a 12-week traditional weight-reduction program were classified on the basis of the Bulimic Investigation Test, Edinburgh (BITE) scores into binge eaters (>/=20), subthreshold binge eaters (10-19), and nonbinge eaters (0-9). This study found a 15.9% prevalence of binge eating. The binge-eating groups (binge eaters and subthreshold binge eaters) were younger, had an earlier onset of obesity, and more psychological distress than nonbinge eaters. Differences in obesity treatment weight loss among binge eaters, subthreshold binge eaters, or nonbingers by last observation carried forward (LOCF) method were not significant. At the end of treatment, the subthreshold binge eaters had the greatest weight loss. Although their binge eating and mood significantly improved, binge eaters and subthreshold binge eaters still had significant pathology in eating behaviors at completion of the program. Alternative treatment strategies focusing on disordered eating behaviors are needed to supplement standard dietary management of overweight treatment-seeking binge eaters.
