急性期医療を担う中堅看護師の職場における自己の存在価値の実感と職務エンパワメント，個人的達成感の関連

Relationship between Realizing Self Worth, Nursing Work Empowerment and Personal Accomplishment of Mid-Career Nurses in an Acute Care Hospital Setting

要旨

　目的：急性期医療を担う関東圏の中堅看護師の職場における「自己の存在価値の実感」と「職務エンパワメント」，「個人的達成感」の関連を検討する．

　対象と方法：急性期医療を担う関東圏の病院に勤務する中堅看護師533名を対象に質問紙調査を実施した．「自己の存在価値の実感」はグレッグ（2005）を参考に3因子7項目にて構成し，構成概念妥当性，信頼性を確認した．さらに共分散構造分析にて「自己の存在価値の実感」と「職務エンパワメント」，「個人的達成感」の関連を検討した．

　結果：269名より回答を得た（有効回答率50.5％）．共分散構造分析の結果（n＝259），「職務エンパワメント」が「個人的達成感」に与える直接的な影響は.10であり，「自己の存在価値の実感」を介した間接的な影響は.21であった．

　結論：「職務エンパワメント」が「個人的達成感」に与える直接的な影響より，「自己の存在価値の実感」を介した間接的な影響の方が大きかった．「自己の存在価値の実感」は急性期医療を担う中堅看護師にポジティブな影響を与える要因として有用であると推察される．

　Purpose: To clarify the relationship between realizing self worth, nursing work empowerment and personal accomplishment of mid-career nurses working in an acute care hospital setting.

　Method: A questionnaire was completed by 533 mid-career nurses working in an acute care hospital setting. The concept of realizing self worth was identified by Gregg (2005). Here, we have developed a scale for realizing self worth that was composed of seven items. The reliability and construct validity of this scale were tested by confirmatory factor analysis, and the relationship between realizing self worth, nursing work empowerment and personal accomplishment was investigated using structural equation modeling.

　Results: The questionnaire was returned by a total of 270 nurses, with 269 valid responses (valid response rate: 50.5%). Structural equation modeling (n=259) showed that the direct effect of nursing work empowerment on personal accomplishment was .10, and that of the indirect effect through realizing self worth was .21.

　Conclusion: These results suggest that the indirect effect through realizing self worth was greater than that of the direct effect. Realizing self worth is therefore important for the implementation of nursing work empowerment in an acute care hospital setting.
