The Reliability and Validity of the Japanese Version of the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC) for Patients with Total Hip Arthroplasty
Bibliographic record
Abstract
本研究の目的は，人工股関節患者における主観的な身体的健康状態の測定するために，Western Ontario and McMaster Universities Osteoarthritis Index（WOMAC）（日本語翻訳版）の信頼性・妥当性を検討することである．術後1年以上の220名を分析した結果，WOMAC下位項目の「痛み」項目で床効果があったが，内的整合性はWOMACの3つの下位尺度内でのCronbach's α係数が0.74～0.95で，29名の再調査によるSpearman相関係数，各項目の一致率が高く，信頼性が示された．SF-36との比較による基準関連妥当性と弁別的妥当性は認められたが，構成妥当性についてはWOMAC（英語原版）と尺度構造が異なる股関節術後患者の身体的な特徴に即した4因子構造の解釈が妥当と考える．日本人股関節術患者において，WOMAC（日本語翻訳版）の信頼性・妥当性が示され，評価指標として有用なことが示唆された．

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
