Abstract
The purpose of this study was to develop a self-evaluation scale for assessing the roles of ward nurses involved in nursing clinical practicum instruction. This study consisted of 4 phases: a) item generation based on findings from qualitative research, b) assurance of the content aspect of construct validity by panel experts and a pilot study, c) item analysis and selection using a survey, and d) evaluation of the reliability and validity of the scale. A 5-point Likert scale was used, comprising 56 items classified into 8 subscales that were based on 19 concepts of behaviors of ward nurses involved in nursing clinical practicum instruction. In the first survey, forms were mailed to 910 ward nurses of 96 randomly sampled hospitals, and 415 valid datasets were analyzed. A total of 32 items were selected based on item analysis. A factor analysis of the scale of 32 items extracted 8 factors that were reflective of the 8 subscales. Chronbach’s alpha of the scale was .944 and Chronbach’s alpha of the 8 subscales ranged from .723 to .835. All hypotheses were verified using the known-groups technique. Moreover, there were significant correlations between the scores of the scale and the scores of the Educational Needs Assessment Tool for Clinical Instructors. In the second survey, forms were mailed to 178 ward nurses of 13 hospitals, and 52 valid datasets were analyzed. The test-retest reliability correlation was .917. The reliability and validity of the finalized scale comprising 32 items classified into 8 subscales were confirmed.
