【方法】まず，同一性地位判定尺度12項目（ISS：加藤，1983）を参照し，原案12項目6 件法を作成した．次に，看護学生A群313名を対象に，本原案を用いて質問紙調査を実施し因子分析を行った．最後に，看護学生B群79名を対象に，因子分析後の尺度を用いて，その信頼性と妥当性の検討を行った． 質問紙には， 属性， 身体的健康感， ストレス感， 多次元自我同一性尺度（MEIS）を加えた．
【結果】A群の有効回答者は284名であり，B群の有効回答者は78名であった．因子分析の結果，8 項目2 因子が抽出され，第Ⅰ因子4 項目を「達成志向」と命名し，第Ⅱ因子4 項目を「寄与志向」と命名した．「達成志向」と「寄与志向」の因子間相関係数は0.63であった．これをSEINSとした．累積寄与率は39.50％であった．信頼性については， α=0.77 とr =0.82 で確認された．
妥当性については，r =0.58 で確認された．SEINS と身体的健康感には，V=0.28 が確認された．
【考察】SEINS と正の相関を認めたMEIS の下位尺度には「心理社会的同一性（社会との適応的な結びつきの感覚）」や「対自的同一性（自己意識の明確さの感覚）」などがあることとSEINS の下位尺度の項目内容から，「達成志向」は「看護の方向性を見定め達成しようとする自己意識」と定義し，「寄与志向」については「看護に積極的に寄与しようとする自己意識」と定義した．SEINS の指標判定については，「23点以下：アイデンティティ拡散傾向」「24－32点：モラトリアム」「33点以上：アイデンティティ確立傾向」と定めた．また，SEINS と身体的健康感との連関係数値から，アイデンティティ状態（拡散－確立）と身体的健康感（悪い－良い）の相互関連性が示唆された．以上の信頼性と妥当性の検討より，開発したSEINS は実用可能な尺度であると判断した．
［Aim］We developed a Scale of Ego-Identity for Nursing Student（SEINS）to measure individual students’ identity（coherent sense of self aspired for by nurses）as nurses, and investigated its reliability and validity.
［Methods］First, with reference to the 12-item Identity Status Scale（ISS）, we created a draft 12-item, 6- Likert scale. Next, using this draft we conducted a questionnaire survey and factor analysis with 313 subjects in nursing student Group A. Finally, using the post-factor analysis scale, we investigated its reliability and validity in 79 subjects in nursing student Group B. Attributes, one item on sense of physical health, one item on sense of strength, and a 4-factor, 20-item identity scale（MEIS）were added to the questionnaire.
［Results］Valid responses were received from 284 subjects in nursing student Group A, and from 78 subjects in nursing student Group B. The results of a factor analysis by unweighted least squares-promax rotation identified 8 items and 2 factors. Factor I with four items was called “achievement orientation,” and Factor II with four items was called “contribution or ientation." The between-factors correlation coefficient for Achievement orientation and Contribution orientation was 0.63. A scale consisting of these 8 items was taken to be SEINS.
The cumulative contribution ratio after factor extraction was 39.50％.
［Discussion］The reliability of SEINS was confirmed with a Cronbach coefficient of =0.77 and reliability coefficient of r=0.82 by test-retest method. The validity of SEINS was confirmed with a correlation coefficient of r=0.58（p<0.01）with MEIS as a reference scale. A Cramer association coefficient of V=0.28（p<0.05）was confirmed for SEINS and sense of physical health. The reliability of SEINS was ensured from the value of Cronbach’s coefficient and the value of the reliability coefficient with a test-retest method. The validity of SEINS was ensured from the value of the correlation coefficient with MEIS, which has a common concept with SEINS. Here, since the subscales of MEIS, which is positively correlated with SEINS, include “psychosocial identity（sense of adaptive links with society）” and “for oneself identity”（sense of clarity of self-awareness）, and considering the content of the sub scales of SEINS , Achievement orientation is defined as “self-awareness in which one attempts to discern and the direction of nursing and achieve its aims,” and Contribution orientation is defined as “self-awareness in which one attempts to actively contribute to nursing.” It was possible to show the indices of SEINS with the total score of 2 factors（8-48）from the between-factors correlation and score distribution of Achievement orientation and Contribution orientation. Consequently, identity status was determined as follows:≤23 points: tendency to diffuse identity; 24-32 points: moratorium;≥33 points: tendency to establish identity. The value of the association coefficient between SEINS and sense of physical health suggests interconnectedness between identity status （diffusionestablishment） and sense of physical health（bad-good）. From the above investigation of reliability and validity, the SEINS scale developed in this study is judged to be a practicable scale., Article, 富山大学看護学会誌, 第14巻1号, 2014.06., page 49-58},
