ABSTRACT

Objective : The purpose of this study was to attest the discriminant-convergent validity through the Factor Analysis of evaluation tool on SS-QOL.Methods : Evaluated the stroke patients through one to one interview by using the evaluation tool of SS-QOL. Data collection towards 130 stroke patients was conducted. In order to attest the validity, conducted Exploratory Factor Analysis and then conducted the Confirmatory Factor Analysis.Results : SS-QOL measures 9 latent variables and it is composed of 36 items by the Exploratory Factor Analysis(EFA). However, EFA tied up conceptually different areas such as the function of upper extremity and self care, mood and personality, and thinking and vision. But EFA just support the empirical aspect, doesn't support the theoretical aspect, we carried out Confirmatory Factor Analysis(CFA). As a result, the upper extremity function and self care were combined as one factor, and in the part of content validity, they were the same concepts. Thinking and vision were divided into two factors experimentally and theoretically. However, in case of mood and personality, they were regarded as one factor experimentally but they need to be divided into 2 because they are two factors in the aspect of psychological theory.Conclusion : The existing evaluation tool of SS-QOL measures 12 latent variables and it is composed of 48 items. However, the result discriminated with 11 latent variables and it is composed of 34 items and its discriminant convergent validity was attested. In the future study, the effort to evaluate the construct validity of SS-QOL evaluation tool should be made.
