女性の新卒看護師のアサーティブネス尺度の開発

Development of a Female Novice Nurse Assertiveness Scale

要旨

目的：新卒看護師のアサーティブネス測定尺度を開発することを目的とした．

方法：質的先行研究と文献研究に基づき，新卒看護師のアサーティブネス尺度の原案を作成した．17病院の新卒看護師1,285人を対象に質問紙調査を実施し，妥当性と信頼性を検証した．

結果：性別によるNNAS原案の総合得点の平均値に差が認められ，女性の有効回答701人を分析対象とした．最尤法，プロマックス回転での因子分析により16項目3因子が抽出された．さらに，確証的因子分析により探索的因子分析で得られた仮説モデルの適合度が確認された．信頼係数は，クロンバックα係数は .81，再テスト法の相関係数 .60，基準関連妥当性の日本版Rathus assertiveness scheduleとの相関係数−.49であった．

結論：信頼性，妥当性は概ね良好であった．

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.
