Reliability and Validity of the Chinese Version of the Nurses' Cancer Pain Management Competency Scale

Background: The Nurses' Cancer Pain Management Competency Scale (NCPMCS) is a tool to explore nurses' competencies and subjective experiences in cancer pain management, and to help nurses understand their current shortcomings in cancer pain management. The scale, currently available only in English and translated into Chinese for wider adoption abroad, provides a tool for Chinese nurses to assess their level of cancer pain management. Furthermore, based on the scale's specific score, they can evaluate their lack of understanding about cancer pain management, advance research into this area, and enhance their capacity to control cancer pain while providing patient care. Objective: The purpose of this study was to translate and localize the new scale, and to measure its reliability and validity. The study was also to provide a way to quickly and accurately measure the competency of cancer pain management among nursing staff in China. Methods: The Bristling translation approach was used to translate, translate back, and culturally modify the English version of the cancer pain management competency scale for nurses to create the Chinese version. A convenience sample was used for the study, 220 clinical nurses from three Grade III hospitals in Zhengzhou, Henan Province, China, were chosen by convenience sampling. The Chinese version of the scale was used for this investigation. Results: The Cancer Pain Management Competency Scale for Nurses has 14 items over 4 dimensions in its Chinese form. From the exploratory factor analysis, four common components were recovered; the cumulative variance rate was 81.994%, the scale's Cronbach's alpha coefficient was 0.902, and the Cronbach's alpha coefficient for each dimension ranged from 0.800 to 0.938. Retest reliability was 0.915, scale content validity was 0.865, and Spearman-Brown's broken half reliability was 0.808. Conclusion: Nurses' cancer pain management competency in clinics can be assessed using the Chinese version of the Nurses' Cancer Pain Management Competency Scale, which has strong validity and reliability.
