Abstract:
OBJECTIVE To analyze the manager post competency evaluation scale in central sterile supply depart-ment based on the iceberg model and test its reliability and validity.METHODS A pool of items was constructed based on literature research and semi-structured interviews.The scale was further refined through expert meetings and a pilot survey.A convenience sampling method was used to select 362 managers from central sterile supply de-partments in medical institutions at various levels in Hunan Province in Jan.2024 as survey subjects.Question-naires were administered,and the reliability and validity of the scale were tested.RESULTS The final version of the scale encompassed five dimensions:personal traits,management abilities,professional abilities,other abili-ties,professional knowledge and skills,with a total of 39 items.The item-level validity coefficients of the scale ranged from 0.83 to 1.00,and the content validity index was 0.93.Exploratory factor analysis revealed a Bartlett's test value of 4 723.828(P＜0.001),a KMO test coefficient of 0.937 and a cumulative variance explanation rate of 74.34％for the five common factors.Confirmatory factor analysis results indicated that the root mean square error of approximation(RSEMA)was＜0.08,the root mean square residual(RMR)was＜0.05,and both the incre-mental fit index(IFI)and comparative fit index(CFI)were＞0.9.The Cronbach's α coefficient of the scale was 0.977,the split-half reliability was 0.955,and the test-retest reliability was 0.952.CONCLUSIONS The manager post competency evaluation scale in central sterile supply departments developed in this study demonstrates rela-tively good reliability and validity.It can effectively evaluate manager post competency and provide references for improving related evaluation systems and optimizing training programs.
