Objectives: This study aimed to develop a competency scale for occupational health nurses involved in health policy decision-making processes and to verify its reliability and validity. Methods: A self-administered questionnaire based on a draft scale was distributed to nurses involved in occupational health activities in the workplace. The analyses included exploratory factor analysis, confirmatory factor analysis, and Cronbach’s alpha coefficient calculations. Results: Questionnaire responses were collected from 183 nurses. The resulting scale consists of 19 items across three factors: “clear planning based on assessment,” “collaboration and coordination regarding health policies,” and “basic skills of occupational health nurses as business people.” Confirmatory factor analysis revealed GFI=.850, AGFI=.803, CFI=.945, and RMSEA=.078. Cronbach’s alpha coefficients were 0.94, 0.90, and 0.87 for the three factors, respectively, and 0.96 for the scale as a whole. Conclusion: The proposed competency scale was confirmed to have acceptable reliability and validity.

Objectives: This study aimed to identify measures by which occupational health nurses and clinical nurses can collaborate to support a balance between treatment and work. Methods: Our research involved verification using the Delphi method among 30 occupational health nurses and 37 clinical nurses experienced in supporting work–treatment balance. Results: Two surveys were conducted after deleting one of the 29 original items and adding three new items based on the suggestions of the research participants. The item deleted was limited to participation in study sessions, etc., only at the “partner” level in the first survey, but was expanded to “between both parties” in the second survey. However, the agreement rate was <80% in both surveys possibly due to the heavy workload of nurses and the novelty of the work–treatment balance support system. Moreover, two of the three items proposed by the participants did not satisfy the agreement rate criteria, but after reviewing the literature and free-form comment section. Conclusion: We deemed it appropriate to include them as measures, with 31 items identified as valid measures.
