Abstract:

objective: To develop a Clinic Readiness to Evidencebased Nursing Assessment（CREBNA）scale and test its reliability and validity. Methods: According to the qualitative interviews, scoping review of promoting action on research implemrntation in health severice (PARIHS) model results obtained primary item pool of CREBNA. After two rounds of experts evaluation，the CREBNA item pool of EBNP readiness was established, the questionnaire was formed based on item pool, the test version of CREBNA was identified by experts, judgment of the relevance between the item and dimensions in the expected structure, and the content validity of questionnaire. Convenience sampling was used in the research, clinical nurses who were participants in training course of Fudan University School of Nursing in 2016 were selected as investigators. The dimensions, reliability and validity of this scale were tested by exploratory factor analysis and reliability analysis. Results: The CREBNA item pool included 3 dimensions,36 items. CREBNA questionnaire of 36 entries was formed based on item pool, the S-CVI of scale was 0.976. 256 questionnaires were included in the final analysis，the correlations between items and the scale total score ranged from 0.482-0.781（P＜0.01），3 factors were extracted by exploratory factor analysis and labeled as Evidence, Context, Facilitation, 62.524% of total variance were explained. The formal scale contained 31 items, The Cronbach α coefficients were 0.959 for the total scale and 0.915-0.940 for the subscales. The testretest reliability was 0.917 and splithalf reliability coefficient was 0.978 for the total questionnaire. Conclusion: It suggested that the CREBNA scale was reliable and valid enough to be applicable to evaluate the evidencebased practice process.
