Abstract
Objectives: To establish a valid and reliable translated version of Derriford Appearance Scale (DAS 59) for Nepali population. Methods: A standard translation-back-translation procedure was used followed by evaluation of semantic, conceptual and society equivalence by the committee and changes were made according to recommendations. This corrected version was pretested and a final version was developed. A validation study was performed using the final version on 424 patients including 212 patients with clinical appearance problems and similar number of young adults who had no concern for facial appearance. Reliability was assessed by cronbach’s alpha value and test-retest correlation coefficient. Discriminate and convergent validity were assessed by comparison between clinical and normal population and correlation with Beck’s Anxiety Inventory(BAI), Beck’s Depression Inventory(BDI)and General Health questionnaire (GHQ) Results: The results indicated excellent internal consistency (Cronbach’s alpha = 0.98) and good test –retest reliability (0.91 for clinical population, 0.86 for normal population). The Discriminate validity was good with statistically significant differences between clinical and normal population .The convergent validity was confirmed by good correlation with other related psychometric tools. Conclusion: A valid and reliable Nepali DAS59 version was developed which can be used for research and clinical assessment of patients with appearance problems and concerns.

Summary
Attractiveness is a visual cue that people use to make assumptions and conclusions about the personality and behavior of others in once-off encounters and it can influence how we treat other. Physical beauty is perceived as a personal characteristic and is valued as such in its own right, independent of other traits [1]. The general consensus is that attractiveness does impact upon how others perceive individuals, such that attractive individuals are associated with more positive social attributes and characteristics. It appears from the literature that society judges an individual’s personal characteristics from their outward appearance at a very young age. An individual’s physical appearance is associated with their inward character so that what is beautiful on the outside is perceived to be beautiful on the inside. The “beautiful equals good” stereotype prevails [2,3,4,5,6,7]
