自傷行為に対する反感態度尺度の日本語版の信頼性と妥当性

Reliability and Validity of the Self-Harm Antipathy Scale-Japanese Version (SHAS-J)

要旨

目的：本研究の目的は，日本語版自傷行為に対する反感の態度尺度（SHAS-J）の信頼性と妥当性を検討することであった．

方法：全国の救命救急センターに勤務する看護師764名を対象に無記名自記式質問紙調査を実施し，302名（39.5％）の有効回答を分析対象とした．質問紙は，対象者の基本情報，SHAS-J，看護師の感情労働尺度，共感的コーピング尺度を用いた．分析は，探索的因子分析，確認的因子分析，相関分析を行った．

結果：探索的因子分析の結果，SHAS-Jは4因子から構成されていた．4因子は「共感的実践力の低さ」，「ケアの反感」，「積極的理解の欠如」，「権利と責任に関する無知」であった．4因子についてCronbach α係数は0.83〜0.54であった．併存妥当性の基準とした共感的コーピング尺度および看護師の感情労働尺度とは有意な相関が認められた．

結論：SHAS-Jは，Cronbach α係数により信頼性が概ね確認された．また，共感的コーピング尺度や看護師の感情労働尺度との関連により妥当性が概ね確認された．

Aim: This study aimed to determine the reliability and validity of the Self-Harm Antipathy Scale-Japanese Version (SHAS-J).

Methods: A self-administered questionnaire was distributed to 764 nurses working in 32 emergency departments across Japan, and 302 (39.5%) of them responded effectively. The questionnaires collected demographic data about the nurses, the SHAS-J, the Emotional Labor Inventory for Nurses (ELIN) and the Empathic Coping Scale. Data were evaluated with Cronbach's alpha along with exploratory factor, confirmatory factor, and correlation analyses.

Results: Factor analysis of the SHAS-J resulted in extraction of four factors. The four factors comprised “low empathic practice competence”, “care futility”, “lack of active understanding” and “ignorance about rights and responsibilities”. Cronbach's alpha for the four factors were 0.83-0.54. The SHAS-J score correlated with ELIN and Empathic Coping Scale scores.

Conclusion: The reliability of the SHAS-J was approximately verified using Cronbach's alpha. Validity of the SHAS-J was approximately confirmed based on its relationships with the ELIN and the Empathic Coping Scale.
