Resilience in Nurses: The Reliability and Validity of the Resilience Scale.

The Resilience Scale (RS) RS-25 and shortened RS-14 have measured resilience but not with nurses. Our purpose was to investigate both for nurses. A random sample of 345 registered nurses from the North Carolina Board of Nursing completed an online questionnaire. Parallel analysis, factor analysis, and receiver operating characteristic analysis were performed. Previous RS factor models had poor confirmatory factor analysis fit. Exploratory factor analysis and item analyses suggested removing items. Good fit was found for an "RS-13" using a bifactor approach. Adequate internal consistency was demonstrated (omega = 0.77-0.90). The RS-13 general factor gave similar accuracy for bullying, physical and mental quality of life, stress, and intent to leave. A shortened RS is comparable in reliability, construct, and convergent validity. It measures nurse resilience well.
