看護学教師の「看護学実習における病態教授活動評価尺度（EPTA-NCP）」の開発—信頼性・妥当性の検証

Developing the "Evaluation Scale for Pathophysiology Teaching Activities in Nursing Clinical Practicum (EPTA-NCP)" for Nursing Faculty: Testing Reliability and Validity

要旨

　目的：看護学教師（以下，教師）の「看護学実習における病態教授活動評価尺度」（EPTA-NCP）を開発し，その信頼性と妥当性を検証する．

　方法：質的研究の結果をもとに，尺度原案37項目を作成した．看護系大学の成人看護学，老年看護学の看護専門領域に所属する教師2年目以上を対象に質問紙調査を行い，構成概念妥当性，内的整合性，基準関連妥当性を検証した．また，尺度の再現性を検証するため再テスト法を行った．

　結果：有効回答385名（有効回答率47.4％）を分析対象とした．探索的因子分析により6因子23項目を示し，確認的因子分析のモデル適合度はGFI＝.899，AGFI＝.858，CFI＝.924，RMSEA＝.063であった．外的基準との相関が認められ，Cronbach's α係数は尺度全体.911であった．さらに再テスト法では有効回答80名（有効回答率39.0％）を分析し，得点間の相関は尺度全体.911であった．

　結論：本尺度の信頼性・妥当性は概ね確保されていることを確認した．

　Objective: To develop the "Evaluation scale for Pathophysiology Teaching Activities in Nursing Clinical Practicum" (EPTA-NCP) for nursing faculty and to test its reliability and validity.

　Methods: A draft of 37 scale items was created based on the results of a qualitative study. A questionnaire survey was conducted on faculty members in their second year or more of teaching in the nursing specialty areas of adult nursing and gerontological nursing at nursing colleges, which was examined for construct validity, internal consistency, and criterion-related validity. The Testretest method was used to verify the reproducibility of the scale.

　Results: 385 valid responses (response rate 47.4％) were subject to analysis. Exploratory factor analysis yielded a 6 factor-structure with 23 items, while a confirmatory factor analysis yielded model fit indices of GFI＝.899, AGFI＝.858, CFI＝.924, and RMSEA＝.063. A significant correlation with external criteria was observed, with Cronbach's alpha coefficient for the overall scale at .911. Furthermore, in the Test-retest method, data from 80 valid responses (response rate 39.0％) were analyzed, and the correlation among scores was .911 for the overall scale.

　Conclusion: The reliability and validity of this scale were found to be generally ensured.
