The purpose of this study is to examine the reliability and validity of The Japanese language version of the Oxford Hip Score (OHS). The scale has been developed to measure Quality of life (QOL) of Total Hip Arthroplasty (THA) patients. The OHS was translated into Japanese, and back translation was performed. Effective responses were obtained from 173 subjects (the collection rate: 97.5% & the valid answer rate: 86.9%) There mean age was 60.7 years (SD=12.3). The subjects were THA patients within three years. In terms of internal reliability, the results were sufficient (Cronbach's alpha was 0.91). In terms of criterion related validity , the Spearman correlation coefficient showed 0.60 and 0.69 between The Japanese language version of the OHS the SF-36v2 (PF, RP, BP). Therefore, this study suggests that the Japanese-language version of the OHS is generally an efficient tool for clinical use. 本研究では人工股関節全置換術（以下THA）患者を対象とした自己記入式疾患特異的QOL尺度Oxford Hip Score（OHS）日本語版を作成し，その信頼性，妥当性を検証した。調査はTHA後，退院後１ ヶ月以上手術後３年以内の173名（男性20名，女性153名，平均年齢60.7（SD±12.3）歳）に行った。OHS日本語版はCronbachα係数（0.91）により信頼性の内的整合性が認められた。妥当性は作成段階で逆翻訳の手法を用い，看護の専門家，翻訳の専門家，THA患者の意見を参考に改良を加えたことで，内容的妥当性が認められた。また，包括的健康尺度MOS36-Item Short-Form Survey v2（SF-36v2）の８下位尺度との相関をSpearmanの相関係数で確認し，基準関連妥当性の同時的妥当性，構成概念妥当性の収束妥当性，弁別妥当性が認められた。OHS日本語版は日本のTHA患者への看護介入効果検討評価に有用な尺度であることが示唆された。
