ABSTRACT
PURPOSE: The purpose of this study was to verify the validity and applicability of the Clinical Ladder System(CLS) Model for nurses and to suggest a model for nurses in general hospitals as well as tertiary hospitals. METHODS: After refining questionnaires through focus group participation, a survey was carried out with 50 nurse managers and 500 staff nurses from 6 tertiary hospitals and 4 general hospitals. S-CVI and i-CVI for validity and applicability were calculated. Differences in validity and applicability by the type of hospitals and characteristics of respondents were analyzed using t-test and ANOVA. RESULTS: S-CVI for validity and applicability of the CLS model were over 0.8 in two types of hospitals and the validity and applicability of the CLS model were confirmed. No differences were found in the total score for validity between the 2 types of hospitals, but in applicability, general hospitals had significantly lower applicability than tertiary hospitals. Some items showed difference according to characteristics of the respondents. CLS models were postulated based on the study results. CONCLUSION: The CLS model refined through this study can be used for nurses. In application, modifications are needed according to the conditions of each hospital.
