Testing the reliability and validity of a newly graduated nurses' teaching experience scale

Guideline-based education provided to newly graduated nurses (NGNs) involves nurse instructors who may be inexperienced, leading to increased burden and anxiety related to teaching NGNs. To support these nurses, this study aimed to test the reliability and validity of a scale measuring the teaching experiences of NGNs. A cross-sectional survey of the original draft of the scale consisting of 72 items, developed based on previous research, was conducted among nurses in their third to fifth years of working in Japanese hospitals with 400 or more beds. Exploratory factor analysis and factor-item consistency were assessed. Responses were obtained from 163 participants, and data from 157 participants were included in the analysis. Exploratory factor analysis revealed 27 items comprising five factors (Factor 1: Experience of receiving cooperation from others, Factor 2: Experience of being there for the NGNs, Factor 3: Experience of feeling positive about teaching, Factor 4: Experience of struggling with teaching, and Factor 5: Experience of teaching according to level of achievement). Cronbach's alpha coefficients ranged from.849 to.923 for each factor and Cronbach's alpha was.924 overall. Factor-item consistency revealed the following: χ2(314) = 637.117 (p < .001), CFI = .871, RMSEA = .081. Each factor in the scale reflects the characteristics of the experience of teaching NGNs, and was found to be reliable and valid. This scale will help managers understand the teaching experiences of novice nurses and provide support based on individualized learning experiences.
