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.
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.
The survey was carried out among 1397 nursing home staff from 50 nursing homes in Southwest China.
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.
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).
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.
提供一份经中国大陆验证的《养老机构患者安全文化调查量表》（NHSOPS）简体中文版本，旨在对 NHSOPS 问卷进行跨文化调适，并评估其心理计量学特性。
构建了一项心理计量学评估研究。首先，采用“翻译-回译-文化调适-预测试”程序引入 NHSOPS。其次，采用横断面调查评估中国大陆版 NHSOPS（M-NHSOPS）的心理计量学特性，然后进行了测试-再测试调查。
该调查在中国西南部的 50 家养老院中，对 1397 名养老院工作人员进行。
采用探索性因子分析（EFA）评估潜在结构，然后进行验证性因子分析（CFA）。采用内容效度指数、克朗巴赫 α 系数和测试-再测试值评估信度。
在 1397 名应答者中，有 1211 名（86.7%）被纳入分析。采用 EFA 探索了一个九因素结构，五个因子（克朗巴赫 α＞0.6）被选入 M-NHSOPS 的新结构。此外，数据表明该量表适合 CFA，且收敛效度和判别效度令人满意。另一方面，M-NHSOPS 包含五个维度和 22 个项目。总体克朗巴赫 α 值为 0.883；各维度值范围为 0.648 至 0.913。此外，内容效度表现良好。最终，测试-再测试信度为 0.892，各维度分别为 0.713、0.809、0.924、0.795 和 0.859（p＜0.001）。
M-NHSOPS 在中国西南部养老院工作人员中具有可接受的信度和令人满意的效度，需要在中国大陆其他地区的样本中进一步验证。
