A confirmatory factor analysis of the novice nurse practitioner role transition scale.

Abstract

As interest in supporting new nurse practitioners' (NPs) transition to practice increases, those interested in measuring the concept will need an instrument with evidence of reliability and validity. The Novice NP Role Transition (NNPRT) Scale is the first instrument to measure the concept. The preliminary exploratory factor analysis revealed a five-factor structure: organizational alignment, mentorship, sense of purpose, perceived competence and self-confidence, and compensation. Using a cross-sectional design and data from 210 novice NPs, the purpose of this study was to confirm the NNPRT Scale's internal factor structure via confirmatory factor analysis (CFA). The sample was primarily female (97.5%), White (75.9%), and certified in primary care (53.5%). The CFA confirmed the five-factor structure, and model fit was improved by moving and omitting items (χ2 [619] = 1277.799, p < 0.001; Root Mean Square Error of Approximation = 0.071 [0.066-0.077]). The final NNPRT Scale includes 37-items, and internal consistency reliability was calculated at 0.95. Convergent validity evidence was supported by a positive, significant correlation with receiving a formal orientation in the first NP position; a negative, significant correlation with turnover intention; and a lack of a relationship with years of prior registered nurse experience. The NNPRT Scale is an instrument with sound evidence of reliability and validity. The NNPRT Scale will be useful for researchers, administrators, and clinicians looking to explore factors that affect NNPRT, as well as by clinicians and administrators implementing programs to support novice NPs' transition to practice.
