Development of the Japanese version of Derriford Appearance Scale DAS59: A QOL index for the people who have problems of appearance

Derriford Appearance Scale 59 (DAS 59) is a new self-report scale to measure psychological well-being for the people who have problems of appearance. We made the Japanese version of the DAS59 and discussed the reliability and validity of the scale. The Japanese version was administered to 292 patients (male=107, female=185) in the field of the plastic surgery and dental surgery and to 320 general population samples (male=119, female=201). The reliability of this scale was enough also in both alpha coefficient and test-retest reliability. We could confirm the validity of the scale from analysis of correlation with other related scales and differences of score between each group, for example, sex and generation. By using the Japanese version in the field of plastic surgery, we will be able to expect not only that clinical decision-making and research are progressed, but also that the people who have problems of appearance are supported appropriately.
