Objective To develop the evaluation scale of core competence in ophthalmic nursing,and test its relia-bility and validity.Methods Based on the literature review,semi-structured interview,and group discussion,the en-try pool of the core competence evaluation scale for ophthalmic nursing was preliminarily developed.The initial scale was formed through expert letter consultation and pre-survey.A total of 210 ophthalmic nurses from 10 Class ⅢGrade A hospitals in Jiangxi province were investigated to test the reliability and validity of the scale.from and Feb-ruary to March 2023.Results There were 51 items in the evaluation scale of core competency of ophthalmology nurs-ing.Six common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 77.380%.The content validity index of total table level was 0.820,and the content validity index of item level was from 0.887 to 1.000.The total Cronbach's α coefficient of the scale was 0.982,and the split-half reliability was 0.875,and the retest reliability was 0.980.Conclusion The evaluation scale of core competence of ophthalmic nurs-ing has good reliability and validity,and can be used as an evaluation tool to evaluate the level of core competence of clinical ophthalmic nursing workers and ophthalmic nurses.
