Objective: To translate and validate the DES-10 into Chinese and adapt the DES-10 among Chinese prostate cancer patients. To explore the impact of demographic data on the SDM of Chinese prostate cancer patients.
Methods: Data were collected from December 2019 to January 2020 from four hospitals among prostatic cancer patients in Henan Province, by convenience sampling method. A demographic questionnaire, DES-10, and 9-item Shared Decision Making Questionnaire (SDM-Q-9) were administered. The exploratory and confirmatory factor analysis was carried out to test the content, construct, reliability, and concurrent validity of the translated DES-10. Then, Pearson’s correlation, t-test, and analysis of variance were used to test the demographic difference of DES-10.
Results: A total of 380 prostatic cancer patients completed the survey (96% response rate). The total score of DES-10 was 71.16± 17.14. The Cronbach’s ɑ coefficient was 0.87. Single factor structure was confirmed by exploratory factor analysis (explaining 50.14% of the variance). Model fitting indexes (RMSEA=0.07, CMIN/DF=2.92) were acceptable. The DES-10 scale showed good validity with the SDM-Q-9 as the criterion. Age, marital status, homeplace, and household monthly income could affect the shared decision-making of prostatic cancer patients.
Conclusion: The DES-10 was demonstrated to be a valid and reliable scale to assess the prostatic cancer patient’s engagement in health care decision-making. And it is culturally appropriate for use in China. The influence of age, marital status, homeplace, and household monthly income should be considered in promoting patients’ participation in shared decision-making.
