BACKGROUND AND PURPOSE
A questionnaire was introduced by the New Zealand Arthroplasty Registry for use when evaluating the outcome of total ankle replacement surgery. We evaluated the reliability, validity, and responsiveness of the modified Swedish version of the questionnaire (SEFAS) in patients with osteoarthritis or inflammatory arthritis before and/or after their ankle was replaced or fused.
PATIENTS AND METHODS
The questionnaire was translated into Swedish and cross-culturally adapted according to a standardized procedure. It was sent to 135 patients with ankle arthritis who were scheduled for or had undergone surgery, together with the foot and ankle outcome score (FAOS), the short form 36 (SF-36) score, and the EuroQol (EQ-5D) score. Construct validity was evaluated with Spearman's correlation coefficient when comparing SEFAS with FAOS, SF-36, and EQ-5D, content validity by calculating floor and ceiling effects, test-retest reliability with intraclass correlation coefficient (ICC), internal consistency with Cronbach's alpha (n = 62), agreement by Bland-Altman plot, and responsiveness by effect size and standardized response mean (n = 37).
RESULTS
For construct validity, we correlated SEFAS with the other scores and 70% or more of our predefined hypotheses concerning correlations could be confirmed. There were no floor or ceiling effects. ICC was 0.92 (CI 95%: 0.88-0.95), Cronbach's alpha 0.96, effect size was 1.44, and the standardized response mean was 1.00.
INTERPRETATION
SEFAS is a self-reported foot and ankle score with good validity, reliability and responsiveness, indicating that the score can be used to evaluate patients with osteoarthritis or inflammatory arthritis of the ankle and outcome of surgery.
背景与目的
新西兰关节置换登记处引入了一份问卷，用于评估全踝关节置换手术后的结果。我们评估了改良的瑞典版问卷（SEFAS）在踝关节置换或融合前后患有骨关节炎或炎症性关节炎的患者中的可靠性、有效性和反应性。
患者与方法
该问卷被翻译成瑞典语，并按照标准化程序进行跨文化适应性调整。它被发送给 135 名计划接受或已经接受踝关节手术的关节炎患者，同时还发送了足踝结局评分（FAOS）、简明 36 项健康调查（SF-36）评分和欧洲五维健康量表（EQ-5D）评分。通过 Spearman 相关系数评估结构效度，当 SEFAS 与 FAOS、SF-36 和 EQ-5D 进行比较时；内容效度通过计算地板和天花板效应来评估；通过组内相关系数（ICC）评估测试-重测可靠性（n = 62）；通过 Bland-Altman 图评估内部一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）；通过 Bland-Altman 图评估一致性和 Cronbach's alpha（n = 62）。
