근로자 업무그릿 측정도구 개발 및 타당화 연구

The purpose of this study was to develop and validate a measurement tool that can measure grit for employees. For this purpose, preliminary items were developed based on the concept of grit, existing tools, and the results of previous studies. Delphi surveys and interviews were conducted to refine the preliminary items. After that, we collected data through a survey, and confirmed the factor structure, final items, and reliability and validity of the measurement tool. For the analysis, CVR values, expert opinions, factor structure, internal/external fit by Rasch model, item difficulty, correlation and structural model were examined. Research results show that, first of all, work grit is an employees’ effort to pursue what he/she has to do and to deal with difficulties in order to achieve a work related goal based on positivity. The final measurement tool consists of 20 items, 3 factors, and a 7-point scale. The three factors were consistency of effort, active learning, and positive thinking. Second, measurement tool’s level of difficulty is suitable for measuring employee’s grit. There are some limitations to measure high work grit employees. In addition, it was found that the work grit tool is suitable for measuring on a 7-point scale. A 7-point scale was found to be appropriate as the step parameter values ​​were varied sequentially. Third, it was confirmed that work grit has concurrent validity with existing grit measurement tools, and appeared as a distinct concept from similar concepts. Fourth, work grit was confirmed to have a statistically significant effect on innovative work behavior, and career satisfaction. It means work grit predict important outcome variables in the field of human resource development. Suggestions were presented based on these research results.
