Abstract
The study aimed to investigate the reliability and validity of the Chinese version of the eating attitudes test (EAT-26) among female adolescents and young adults in Mainland China. This scale was administered to 396 female eating disorder patients and 406 noneating disorder healthy controls, in addition 35 healthy controls completed a retest after a 4-week intervals. Tests for reliability, convergent validity and receiver operating characteristic analysis were performed to detect the psychometric properties. The EAT-26 demonstrated good internal consistency (Cronbach's alpha = 0.822-0.922), test-retest reliability (interclass correlation coefficient = 0.817) and convergent validity(r = 0.450-0.750). The receiver operating characteristic analysis showed that the cut-off 14 for anorexia nervosa and 15 for bulimia nervosa represented good compromises with approximate sensitivity (0.66-0.68) and specificity (0.85-0.86). Our findings provided evidence that the Chinese version of the EAT-26 was a psychometrically reliable and valid self-rating instrument for identifying people suffering from an eating disorder in Mainland China. A clinical cut-off range between 14 and 15 could be used, but caution should be exercised because of the low sensitivity of the tool.

Highlights
Introduction and aimsEating disorders (EDs) have been found to affect young females (Hudson, Hiripi, Pope, &Kessler, 2007) and to be common in developed countries(Dolan, 1991)
A number of assessment tools for EDs have been developed to be used in clinic and research settings and some of them have been translated in order to be used in China, such as the Eating Attitudes Test 26-item version (EAT-26) (Garner, Olmsted, Bohr, & Garfinkel, 1982; Lee, Kwok, Liau, & Leung, 2002), the Eating Disorder Examination (EDE) (Tong et al, 2011), or the Eating Disorder Inventory(EDI-1)
Bonferroni post hoc tests showed that the scores of most of the groups differed significantly from one another: Patients with bulimia nervosa (BN) had the highest scores, and healthy control (HC) controls had the lowest scores
Summary
Introduction and aimsEating disorders (EDs) have been found to affect young females (Hudson, Hiripi, Pope, &Kessler, 2007) and to be common in developed countries(Dolan, 1991). In addition EDs and weigh concerns are becoming more prevalent in developing China(Huon, Qian, Oliver, & Xiao, 2002; Lee, S.,& Lee, A. The EDE and EDI-1 have demonstrated to have good validity and reliability among the Mainland Chinese EDs population(Tong et al, 2011; Zhang,& Kong, 2004), they are limited by their length. This makes them unsuitable to be used in primary care settings. The results of these studies showed differences in EDs symptomatology between people from Hong Kong and Mainland China, suggesting the need to re-establish the validity and reliability of EAT-26 in female EDs population in Mainland China
