Abstract

BACKGROUND: Eating disorder, which is prevalent among young women and adolescents, is a disease with a high mortality rate. KEAT-26(The Korean Version of Eating Attitudes Test-26) is screening tool for eating disorder commonly used in Korea. The Korean Version of SCOFF questionnaires(K-SCOFF) which is more usable for outpatients than KEAT-26 was assessed for its reliability.
METHODS
Five hundreds college women from a women university in Seoul were studied using a self-recorded questionnaires. Contents of questionnaires included demo-graphic characteristics, The Korean version of SCOFF (K-SCOFF), and Korean version EAT-26(KEAT-26). K-SCOFF questionnaires was readministered to forty women 14 days after answering the first in order to evaluate the questionnaire's test-retest reliability.
RESULTS
Total number of respondent were 417, the response rate was 83.4%, and mean age was 20.73+/-2.02. Weight, height, and BMI is 52.61+/-6.99kg, 162.95+/- 4.45cm, and 19.81+/-2.03kg/m2, respectively. The preva-lence of obesity is 2.0%. The internal consistency relia- bility of each scale score, estimated by Cronbach's alpha coefficients, was 0.40. The test-retest reliability by Spear-man correlation coefficient was 0.58
CONCLUSION
K-SCOFF questionnaires were inappro- priate for improving screening of eating disorders due to low internal consistency reliability according to our study.
