看護師長を対象としたワーク・ライフ・バランス実現度尺度の開発

Development of a Work-Life Balance Achievement Scale for Head Nurse

要旨

　目的：看護師長を対象としたワーク・ライフ・バランス実現度尺度を開発し，尺度の妥当性と信頼性を検討する．

　方法：国内の100床以上の病院に勤務する看護師長786名を対象に，尺度原案43項目の質問紙調査を実施し，尺度の妥当性と信頼性を検討した．

　結果：回収数571名（回収率72.6％）のうち有効回答479名（有効回答率83.9％）を分析の対象とした．探索的因子分析の結果，6因子27項目が抽出された．確認的因子分析の結果，仮説モデルの適合度が確認された．基準関連妥当性は，看護職の仕事と生活の調和実現度尺度との相関により確認された．尺度全体のCronbachのα係数は .911，各因子で .710〜.902であった．再テスト法による尺度全体の信頼性係数 .862であった．

　結論：看護師長を対象としたワーク・ライフ・バランス実現度尺度の妥当性と信頼性が確認された．

　Objective: To develop a work-life balance achievement scale for head nurses and to examine the validity and reliability of the scale.

　Methods: A questionnaire survey consisting of 43 items was administered to 786 head nurses working in hospitals with 100 or more beds in Japan. We examined the validity and reliability of the scale.

　Results: We received 571 responses (72.6% response rate), of which 479 valid responses (83.9% valid response rate) were included in the analysis. Six factors and 27 items were extracted from an exploratory factor analysis. Confirmatory factor analysis confirmed the goodness of fit of the hypothesized model. Criterion-related validity was confirmed by correlation with the Work-Life Balance Scale for Nurses. Cronbach's alpha coefficient for the overall scale was .911 (range of each factor, .710 to .902). The overall reliability coefficient of the scale using the retest method was .862.

　Conclusion: The validity and reliability of the Work-Life Balance Achievement Scale for Head Nurse were confirmed.
