Transcultural adaptation and psychometric evaluation of the mainland China version of Nursing Home Survey on Patient Safety Culture Questionnaire: a cross-sectional survey based on 50 nursing homes in China.

OBJECTIVE: To provide a validated Chinese-language measurement of the Nursing Home Survey on Patient Safety Culture (NHSOPS) in mainland China. The primary goal is to carry out a transcultural adaptation of the NHSOPS Questionnaire into Chinese and evaluate its psychometric properties.
DESIGN: A psychometric evaluation study is constructed. First, the 'translation-back-translation-cultural adaptation' and the pretesting procedure were followed to introduce the NHSOPS. Second, a cross-sectional survey was used to assess the psychometric properties for the mainland China version of the NHSOPS (M-NHSOPS), and a test-retest survey was then applied. SETTING AND PARTICIPANTS: The survey was carried out among 1397 nursing home staff from 50 nursing homes in Southwest China. OUTCOME MEASURES: Exploratory factor analysis (EFA) was used to assess the potential structure, and confirmatory factor analysis (CFA) was then applied. Reliability was assessed by the content validity index, Cronbach's α and the test-retest value.
RESULTS: Among the 1397 respondents, 1211 were included (86.7%). EFA was used, and a nine-factor structure was explored. Five factors (Cronbach's α ＞0.6) were selected into the new structure for the M-NHSOPS. Moreover, data showed that it was suitable for CFA, and convergent validity and discriminant validity were satisfactory. On the other hand, M-NHSOPS contains five dimensions and 22 items. The overall Cronbach's α value was 0.883; the values of each dimension ranged from 0.648 to 0.913. Additionally, content validity showed significant performance. Eventually, test-retest reliability was 0.892, and each dimension was 0.713, 0.809, 0.924, 0.795 and 0.859, respectively (p<0.001).
CONCLUSIONS: M-NHSOPS has acceptable reliability and satisfactory validity among staff of nursing homes in Southwest China, and further verification among samples in other regions of mainland China is required. © Author(s) (or their employer(s)) 2021.
