Introduction. The Manchester Foot Pain and Disability Index (MFPDI) is a 19-item questionnaire for the assessment of disability caused by foot pain. The aim was to develop a Danish language version of the MFPDI (MFPDI-DK) and evaluate its reproducibility and construct validity. Methods. A Danish version was created, following a forward-backward translation procedure. A sample of 84 adult patients with foot pain was recruited. Participants completed two copies of the MFPDI-DK within a 24- to 48-hour interval, along with the Medical Outcomes Study Short Form 36 (SF-36), and a pain Visual Analog Scale (VAS). Reproducibility was assessed using the intraclass correlation coefficient (ICC) and 95% limits of agreement (Bland-Altman plot). Construct validity was evaluated with Pearson's Rho, using a priori hypothesized correlations with SF-36 subscales and VASmean. Results. The MFPDI-DK showed very good reliability with an ICC of 0.92 (0.88-0.95). The 95% limits of agreement ranged from -6.03 to 6.03 points. Construct validity was supported by moderate to very strong correlations with the SF-36 physical subscales and VASmean. Conclusion. The MFPDI-DK appears to be a valid and reproducible instrument in evaluating foot-pain-related disability in Danish adult patients in cross-sectional samples. Further research is needed to test the responsiveness of the MFPDI-DK.
引言。曼彻斯特足部疼痛与残疾指数（MFPDI）是一份包含19个条目的问卷，用于评估足部疼痛所致的残疾情况。本研究旨在开发丹麦语版的MFPDI（MFPDI-DK），并评估其重测信度和结构效度。方法。按照正反翻译程序创建丹麦语版。招募了84例足部疼痛的成年患者。参与者在24至48小时内完成两份MFPDI-DK问卷，同时完成医学结局研究简明健康调查36项量表（SF-36）和疼痛视觉模拟量表（VAS）。使用组内相关系数（ICC）和95%一致性界限（Bland-Altman图）评估重测信度。使用Pearson相关系数Rho评估结构效度，采用与SF-36分量表和VAS均值的先验假设相关性。结果。MFPDI-DK显示出非常好的信度，ICC为0.92（0.88 - 0.95）。95%一致性界限范围为 - 6.03至6.03分。与SF-36身体分量表和VAS均值的中度至非常强的相关性支持了结构效度。结论。在横断面样本中，MFPDI-DK似乎是评估丹麦成年患者足部疼痛相关残疾的有效且可重复的工具。需要进一步研究来测试MFPDI-DK的反应度。
