Analysis on reliability and validity of adaptation OSSIQ in measuring life quality of populatios with different types of subjective skin / 吉林大学学报(医学版)

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 (P1.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.
