Investigation of the Reliability and Validity of a Scale to Reflect on Nursing Support in Patients' Treatment Decisions: Focusing on Nurses Who Provide Nursing Support for Patients' Treatment Decisions on a Daily Basis

要旨

　目的：日常的に治療決定の看護支援を行う看護師を対象とした患者の治療決定における看護支援の振り返り尺度の信頼性と妥当性を検討する．

　方法：対象者に，自記式質問紙を配布し郵送法にて回収した．調査内容は，対象者の属性，患者の治療決定における看護支援の背景，患者の治療決定における看護支援の振り返り，社会的クリティカルシンキング志向性，臨床看護師の道徳的感性である．

　結果：有効回答は539部（39.7％）であった．項目分析と探索的因子分析により21項目5因子構造を確認した．確認的因子分析によるモデル適合を行い，外的基準との相関が認められ，Cronbachのα係数は項目全体では.935，因子別では.875〜.696であった．

　考察：本尺度は一定の信頼性と妥当性があることが確認されたため，看護師が臨床で治療決定の支援をする場面での判断力の自己評価として用いることが可能である．

　Aim: To investigate the reliability and validity of a scale to reflect on nursing support in patients' treatment decisions by nurses who provide nursing support for treatment decisions on a daily basis.

　Methods: A self-administered questionnaire was distributed to nurses, and were collected by mail. The contents of the survey include the attributes of the subjects, the background of nursing support in the treatment decision for the patient, the scale that reflects the nursing support in patients' treatment decisions, their orientation toward social critical thinking scale, and a moral sensitivity test for clinical nurses.

　Results: We received 539 (39.7%) effective responses. The items and exploratory factors were analyzed, and the structure of 21 items and 5 factors was confirmed. Model fit by confirmatory factor analysis, and the correlation with external criteria is Admitted. Cronbach's α coefficient was .935 for all items and .875 to .696 for each factor.

　Conclusions: This scale has a certain reliability and validity, making it is possible for nurses to do self-evaluation of their judgment in giving support of treatment decisions in clinical settings.
