看護管理者のキーコンピテンシー尺度の開発

Development of Key Competency Scale of Nursing Manager

要旨

　目的：看護管理者のキーコンピテンシー尺度を開発する．

　方法：特定機能病院と地域医療支援病院に勤務する看護管理者4,410名を対象に質問紙調査を実施した．看護管理者のキーコンピテンシー50項目の項目分析と因子分析を行った．構成概念妥当性はモデルの適合度指標を用いて確認，併存妥当性は看護管理者のコンピテンシー評価尺度（NACAS）を用いて確認した．信頼性はCronbachのα係数で内的整合性を確認した．

　結果：看護管理者2,480名から回答が得られ（回収率56.2％），有効回答2,330名を分析対象とした．因子分析の結果，5因子30項目（状況認識，メタ認知，自己管理，キャリア支援，意思決定）が抽出された．モデルの適合度はGFI = .907，AGFI = .899，CFI = .921，RMSEA = .047であり構成概念妥当性が確認された．5因子とNACASの下位概念との相関はr = .34〜.63であり併存妥当性が確認された．5因子のα係数は .81〜.88であり内定整合性が確認された．

　結論：看護管理者のキーコンピテンシー尺度の信頼性と妥当性が検証された．

　Objective: To develop a key competency scale of nursing manager.

　Methods: A questionnaire survey was conducted on 4,410 nursing managers who work at facilities of University hospital and facilities of regional medical support hospitals. We set 50 items on key competencies of nursing manager, and performed item analysis and factor analysis. The construct validity is checked the model to validity confirm and the coexistence validity is checked using NACAS; Nursing Administrator's Competency Assessment Scale. The reliability confirmed internal consistency by Cronbach's alpha coefficient.

　Results: A total of 2,480 nursing manager were response (collection rate 56.2%) and 2,330 valid responses were analyzed. Five factors were extracted as a result of factor analysis, situation awareness, meta-cognitive, self-control, career support, decision making. The fitness of the model consisting of 5 factors and 30 items was GFI = .907, AGFI = .899, CFI = .921, RMSEA = .047, and the construct validity was confirmed. The correlation between the extracted five factors and lower-level concepts of NACAS was r = .34 to .63, confirmed coexistence validity. The alpha coefficient of each factor was .81 to .88, confirmed the internally defined consistency.

　Conclusions: The reliability and validity of the key competency scale of nursing manager; KCSNM were verified.
