Abstract:
Objective To develop the Quality of Life Scale for Patients with Aplastic Anemia(QLS-AA)and to test its reliability and validity.Methods According to the concept category and the four-dimensional model of quality of life,the scale item pool was initially constructed through literature review and qualitative interview.The draft of the QLS-AA was formed through expert inquiry,cognitive interviews and expert consultation.A questionnaire survey was conducted on 429 patients with aplastic anemia from the hematology departments of a tertiary general hospital in Zhejiang Province and a tertiary hematology hospital in Tianjin with the convenient sampling method from December 2021 to November 2022,and the item analysis and reliability,validity test of the pre-test scale were carried out.Results 422 valid questionnaires were collected,and the effective questionnaire recovery rate was 98.37％.3 common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 66.113％.The scale level consensus content validity index was 0.821,the scale level average content validity index was 0.970,the item level content validity index was 0.833～1.000,and the correlation coefficient with SF-36 was 0.719.The Cronbach's α was 0.944,and the split half reliability was 0.882,and retest reliability was 0.931.The final QLS-AA includes 3 dimensions with 39 items.Conclusion The process of developing QLS-AA in this study is scientifically standardized,and the scale has good reliability and validity,which can effectively evaluate the quality of life for patients with aplastic anemia.
