Aim: This study aims to develop a novice nurse assertiveness scale to enable the provision of support of assertiveness.
Methods: We created a draft novice nurse assertiveness scale based on qualitative, previous studies and literature review, and examined the validity and reliability by administering a questionnaire survey to 1,285 novice nurses working in seventeen hospitals.
Results: Because there was a difference in the mean total scores of the draft NNAS between male and female, we determined to analyze 701 female novice nurses. Sixteen items and three factors were extracted using factor analysis that uses the maximum likelihood technique with promax rotation.
Further, we performed a confirmatory factor analysis to test the fitness of the hypothetical model obtained from an explanatory factor analysis, and obtained the following confidence coefficients: a Cronbach’s alpha of .81, a correlation coefficient of .60 from a test-retest, and a correlation coefficient of –.49 with the J-RAS (Japanese version of the Rathus assertiveness schedule).
Conclusion: The validity and reliability of the scale developed in this study was on the whole excellent.
