Reliability and validity assessment of Chinese version of nursing home survey on patient safety culture

Objective To translate the English version of nursing home survey on patient safety culture (NHSPSC) into Chinese one, and to test the reliability and validity of Chinese version of NHSPSC. Methods The items of NHSPSC were translated into Chinese version using a standard procedure of double-back translation and cross-culture adapted. A total of 237 staff members of nursing home were recruited to examine the reliability and validity of Chinese version of NHSPSC. Results The Chinese version of NHSPSC consisted of 36 items. The Cronbach′s α coefficient was 0.847 for the total scale and Cronbach′s α of each factors ranged from 0.632 to 0.832. The test-retest reliability was 0.822. The correlation coefficient between each dimension score ranged from 0.151 to 0.728 and the correlation coefficient between each dimension and the total score ranged from 0.294 to 0.779. The content validity index was 0.873. Twelve factors were extracted by factor analysis which could explain 63.156% of the total variance. Conclusions The Chinese version of NHSPSC is reliable and valid, which can be used to evaluate the patient safety culture in nursing homes.
