Abstract: Objective: To evaluate the reliability and validity of the adaptation OSSIQ in measuring the life quality of the populations with different types of subjective skin. Methods: A stratified samplings strategy was adopted to select 140 college students, workers, personnel of enterprises and institutions aged 18-60 years old.The reliability and validity of adaptation OSSIQ were evealuated using internal consistency validity, split half reliability, and construct validity. Results: The adaptation OSSIQ had a Cronbach's α efficient of 0.924 and 0.902. Split half reliability, the Spearman-Brown before and after skin care were 0.877 and the Guttman Split-Half coefficients were 0.876 and 0.874 respectively.Contentvalidity, the Item-scale correlation coefficients exceed 0.5 (P<0.001) before and after skin care.Satisfactory (100%) convergent validity and discriminant validity were found.The contract validity was checked by factor analysis; after quartimax rotation, the researcher extracted the factors by the default principle of eigenvalue>1.Each factor consisted of the items with factor loading≥0.6;the load factor value belonged to high level (≥0.6) by factor analysis. Conclusion: Adaptation OSSIQ has good reliability and validity for the evaluation on life quality of the populations with different types of subjective skin.It can be used to evaluate the influence of different types of skin in the life quality.

Key words: adaptation OSSIQ, reliability, subjective skin types, life quality, validity
