Development of a Support Assessment Scale of On-site Nursing Instructors Based on the Perceptions of Novice Nurses

要旨

　目的：新卒看護師が認識する実地指導者のサポート評価尺度を開発する．

　方法：新卒看護師のサポートに関する文献と質的研究を基に尺度原案を作成した．首都圏内にある大学病院と国立系病院10施設の新卒看護師を対象に質問紙調査を行い，尺度の妥当性と信頼性を検証した．

　結果：有効回答は553名（72.2％）であった．性別，社会人経験の有無，最終学歴の違いによる尺度原案の総合得点の平均値に有意差はみとめず，有効回答全数を分析対象とした．項目分析後，探索的因子分析（最尤法，プロマックス回転）を行い【実践面のサポート】と【情緒面のサポート】の2因子17項目が抽出された．確証的因子分析によるモデルの適合度はGFI＝.903，AGFI＝.875，RMSEA＝.072で，基準関連妥当性の相関係数は.723，クロンバックα信頼係数は.952，再テスト法の級内相関係数は.697であった．

　結論：新卒看護師が認識する実地指導者のサポート評価尺度は許容範囲の信頼性と妥当性が検証された．

　Purpose: This study aims to develop a support assessment scale of on-site nursing instructors based on the perceptions of novice nurses.

　Methods: A draft scale was created based on the literature and qualitative studies related to the support provided for novice nurses. The validity and reliability of the scale was evaluated with a questionnaire survey administered to novice nurses working in ten university hospitals and national hospitals in the Tokyo metropolitan area.

　Results: The number of valid responses was 553 (72.2%). Since no significant differences were found in the mean total scores of the draft scale depending on the gender, working experience as a member of society, and final educational background, all the valid responses were included in the analysis.

　After performing an item analysis, we performed an exploratory factor analysis with the maximum likelihood method and promax rotation. The analysis identified 17 items in the following two factors: [practical support] and [emotional support]. The goodness of fit of the model by confirmatory factor analysis was GFI = .903, AGFI = .875, and RMSEA = .072. The correlation coefficient for the criterion-related validity was .723, the Cronbach's coefficient alpha was .952, and the intraclass correlation coefficient by a test-retest was .697.

　Conclusion: Acceptable reliability and validity of the support assessment scale of on-site nursing instructors perceived by novice nurses were verified.
