Development of a Japanese Version of the Mental Health-Related Self-Care Agency Scale

要旨

　Mental Health-Related Self-Care Agency Scale日本語版（MH-SCA-Japanese：以下MHSCA-J）の開発とその信頼性，妥当性を検証することを目的とした．

　MH-SCAの翻訳を行い，内容妥当性・表面妥当性を検討し，MH-SCA-Jを作成した．地域で生活しているうつ症状のある精神障がい者73名を対象に調査を行った．結果は，MH-SCA-JのCronbachα係数は0.93であり，一定の内的一貫性が確認された．MH-SCA-Jとセルフケア行動の得点の相関係数は－0.690（p＜0.01），MH-SCA-JとCES-Dの得点の相関係数は－0.834（p＜0.01）と統計的に有意な相関がみられ，併存的妥当性が確認された．また，“抑うつ症状なし群”は“抑うつ症状あり群”と比較してt値は－7.51（p＜0.01）であり，有意にMH-SCA-J得点が高く，臨床的妥当性が確認された．以上より，MH-SCA-Jは一定の信頼性と妥当性が得られ，精神症状に関連するセルフケア能力を測定する尺度として使用可能と考え

Abstract

　Aim：The purpose of this study is to develop the Japanese version of the Mental Health- Related Self-Care Agency Scale（MH-SCA） and to establish its validity and reliability.

　Method：Using the committee approach, the MH-SCA was translated from English into Japanese. To ensure the semantic, conceptual, and normative equivalence with the original instrument, the committee included five translators：one adjudicator, two translation reviewers, one self-care specialist, and one experienced researcher in questionnaire design and pretesting. The steps were：prepare, translate, pretest, revise, and document. The finalized MH-SCA-Japanese version（MH-SCA-J） was conducted on 73 Japanese outpatients with depression to address reliability and construct validity for the MH-SCA-J.

　Result：The Cronbach's alpha for the MH-SCA-J was 0.93, supporting reliability by determining internal consistency. The total score of the MH-SCA-J was significantly correlated to the scores of CES-D, -0.834（p＜0.01）, and to the scores of daily activities, -0.690（p＜0.01）. Therefore, concurrent validity was confirmed. Additionally, as a result of having compared a group of depressed people with a group of nondepressed people, the depressed people were clearly differentiated from the nondepressed people by this instrument. These mean scores of MH-SCA-J, 97.16 for the depressed and 131.83 for the nondepressed, were significantly different, t＝-7.51（p＜0.01）, therefore, clinical validity was confirmed.

　Conclusion：In conclusion, the MH-SCA-Japanese version was developed and its validity and reliability were confirmed. These results show that the MH-SCA-Japanese version can be used to measure the self-care agency of people with mental disability.
