訪問看護管理者のリーダーシップ行動尺度の開発

Development of a Leadership Behavior Scale for Visiting Nurse Managers

要旨

　目的：訪問看護管理者のリーダーシップ行動尺度の開発を行うこと．

　方法：全国の訪問看護師3,000名を対象に，管理者のリーダーシップの行動に関する他者評価尺度39項目を含むインターネット調査または質問紙郵送調査を実施し，尺度の信頼性および妥当性の検討をした．

　結果：577名（回収率19.3％）から回答が得られ，探索的因子分析の結果，2因子16項目が抽出された．モデル適合度はGFI＝.936，AGFI＝.909，CFI＝.973，RMSEA＝.062で，外的基準との相関係数はr＝.768〜.818であった．尺度全体のクロンバックα係数は.959，再テスト法による相関係数はr＝.716であった．

　結論：一定の信頼性および妥当性を有すること，良好なモデル適合度を示したことから，本尺度は訪問看護管理者のリーダーシップの行動を評価する指標として活用可能である．

　Objective: This study aimed to develop a scale for measuring the leadership behaviors of visiting nurse managers.

　Methods: A nationwide survey was conducted using internet-based or mailed questionnaires targeting 3,000 visiting nurses across Japan. The survey included a 39-item scale designed to evaluate managers' leadership behavior from the perspectives of their subordinates. The reliability and validity of the scale were also assessed.

　Results: In total, 577 responses were received (response rate: 19.3%). Exploratory factor analysis identified 16 items organized into two factors. The model fit indices were as follows: GFI=.936, AGFI=.909, CFI=.973, and RMSEA=.062. Correlation coefficients with external criteria ranged from r=.768 to .818. Cronbach's alpha for the complete scale was .959, and the test-retest correlation coefficient was r=.716.

　Conclusions: The scale demonstrated strong reliability and validity, as well as favorable model fit indices. This suggests that it is a robust tool for evaluating visiting nurse managers' leadership behavior.
