Abstract
BACKGROUND: Conscientious objection poses ethical dilemmas frequently encountered by nurses, allowing them to prioritize personal beliefs in caregiving. However, it may also be viewed as a stance jeopardizing patients' healthcare access. There is no measurement tool to measure conscientious objection in nurses. This study aimed to develop a measurement tool for nurses' conscientious objection attitudes. METHODS: This research is a methodological study conducted with a total of 261 nurses in Turkiye. Following content validity assessments by ten experts, a 29-item draft scale was developed. Exploratory and confirmatory factor analyses examined the factor structure, and reliability was assessed via the Spearman-Brown coefficient, intraclass correlation coefficient (ICC), and Bland Altman plot. Cronbach's alpha estimated internal consistency and discrimination, which were evaluated by comparing lower and upper 27% groups. RESULTS: The Nurses' Conscientious Objection Attitude Scale (COAS-N) comprises 29 items and three sub-dimensions (prioritizing professional values, prioritizing personal values, and requesting the right to conscientious objection). Cronbach's alpha for the entire scale is 0.81. CONCLUSION: Validity and reliability were established for the newly developed scale measuring nurses' conscientious objection attitudes.
