Abstract

Abstract: Objective: To translate the English version of Perceived Control In Health Care Questionnaire into Chinese, and to analysis the reliability and validity of Chinese Version of PCHCQ. Methods: We adapted the English version of PCHCQ into Chinese according to Brislin 's translation model, including translation, back translation and cross-cultural adjustment. Using the convenient sampling method, 315 elderly people from a nursing home in Guangzhou were selected as the participants to between June and September 2017. 20 participants were selected from those who had actively responded to the survey for the test- retest 2 weeks later. We set 27% of the participants with the total scores ≥117 as the high-score group (n = 91) and the total scores ≤90 as the low-core group (n = 88). Compared the average difference between each item of the two groups and investigated the item-total correlation by linear analys; The validity analysis was assessed by content validity, criterion-related validity and exploratory factor analysis. The Cronbach's ɑ and test-retest reliability were used for reliability analysis. Result: There were significant differences between the high-score group and the low-core group in the scores for each item ( P < 0.001). The correlation coefficient between each item and the total score of the questionnaire was 0.468–0.811 ( P < 0.001). The item-level content validity index (I-CVI) was between 0.83 and 1.00, and the scale-level CVI (S-CVI/Ave) was 0.98. The results of criterion-related validity showed that there was a positive correlation between the Chinese version PCHCQ and the Mastery Scale Chinese version (MSC) in the scores ( r = 0.670, P < 0.001). EFA showed KMO = 0.925, Banlett spherical test χ 2 = 6646.178 (df = 300, P < 0.001), and five common factors were extracted which explained the total variance of 73.884%. The Cronbach's ɑ of the total questionnaire was 0.919, and the Cronbach's ɑ of each factor was 0.746–0.897 ( P < 0.001). The test-retest reliability of the total questionnaire was 0.949, and the test-retest reliability of each factor was 0.941–0.724 ( P < 0.001). Conclusion: Chinese Version of PCHCQ showed good reliability and validity and it can be used in health-related control of the study among the elderly in China.
