Developing Student Evidence-Based Practice Questionnaire (S-EBPQ) for undergraduate nursing students: Reliability and validity of a Chinese adaptation.

Rationale, Aims, And Objectives: The assessment of evaluating undergraduate nursing students' evidence-based practice engagement is an important issue, yet few tools have been developed specifically in Mainland China. The purpose of this study was to adapt the Student Evidence-based Practice Questionnaire (S-EBPQ) to Mainland China's cultural context and to evaluate the psychometric properties of the newly adapted Chinese S-EBPQ.

Methods: Cross-cultural adaptation, including translation of the original S-EBPQ into Mandarin Chinese language, was performed according to published guidelines. A pilot study was conducted in Mainland China with 25 Chinese undergraduate nursing students. A subsequent validation study was conducted with 400 undergraduate nursing students from Mainland China. Construct validity was assessed by exploratory factor analysis (n = 190) and confirmatory factor analysis (n = 210). Reliability was determined using internal consistency and test-retest reliability.

Results: The split-half coefficient for the overall Chinese S-EBPQ was 0.858. A content validity index of 0.986 was achieved. Principal component analysis resulted in a 4-factor structure explaining 68.285% of the total variance. The comparative fit index was 0.927, and the root mean squared error of approximation was 0.072 from the confirmatory factor analysis. Known-group validity was supported by the significant differences according to various characteristics of participants. Internal consistency was high for the Chinese S-EBPQ reaching a Cronbach α value of 0.934. Test-retest reliability was 0.821.

Conclusion: The newly cross-culturally adapted S-EBPQ possesses adequate validity, test-retest reliability, and internal consistency and therefore may be utilized in nursing education to assess EBP of undergraduate nursing students in Mainland China.
