要旨

目的：中堅前期看護師の自己イメージ評価表を作成し，その信頼性と妥当性を検討することである．

対象と方法：臨床経験3年以上20歳代看護師1,458名を対象に無記名自記式質問紙調査を実施した．項目分析，因子分析を用いた構成概念妥当性の検討により評価表を構築し，内的整合性，併存妥当性の検討を行った．

結果：分析対象は569名であった．分析の結果，16項目5因子構造【疲れている私】【孤独な私】【迷っている私】【未熟な私】【頑張っている私】の「中堅前期看護師の自己イメージ評価表」が完成した．評価表全体のCronbach's α係数は.872，下位因子の係数は.544 から.816 であり内的整合性が得られた．併存妥当性は自尊感情尺度（Self-Esteem Scale）と有意な正の相関，抑うつ自己評価尺度（CES-D）と有意な負の相関が認められた．

結論：信頼性と妥当性が確保された16項目5因子構造の中堅前期看護師の自己イメージ評価表を作成できた．

Objective: To develop a self-evaluation questionnaire to measure the self-image of nurses in the early stages of their mid-careers.

Subjects and Methods: Nurses in their twenties with more than three years of clinical experience were selected as subjects of this study. A self-evaluation questionnaire to evaluate their self-image was developed, and its adequacy was reviewed by use of article analysis, exploratory factor analysis, and its reliability and criterion-related validity.

Results: The number of subjects was 569. As a result of the analysis, a model with 5 items containing and 16 factors was developed and called “Self-evaluation questionnaire of self-image of nurses in the early stages of their mid-careers.” The 5 items included “My tired self,” “My isolated self,” “My lost or worried self,” “My unskilled self,” and “My striving self.” The trust factor obtained for the entire measure was .872, and the subscale for internal consistency was .544 to .816. Concurrent validity, significant positive correlation with the self-esteem scale, CES-D and significant negative correlation were then observed.

Conclusion: The self-evaluation questionnaire of the self-image of nurses in the early stages of their mid-careers, reliability and validity has been confirmed.
