The aim of our study was to develop a Dutch version of the Foot Health Status Questionnaire (FHSQ-NL) and evaluate its measurement properties according to the COSMIN definition (COnsensus-based Standards for the selection of health Measurement INstruments). After translation of the FSHQ, a group of 119 randomly selected patient who visited the outpatient clinic for conditions affecting the foot and ankle were asked to participate, of which103 patients were included in the analysis. The FHSQ-NL, a validated Dutch FAOS and a visual analogue scale (VAS) for pain and function were used in this study as outcomes measures. Reliability was assessed by calculating intraclass correlation coefficient (ICC), internal consistency by Cronbach's alpha, and the smallest detectable change (SDC). Construct validity was evaluated by use of a priori hypotheses concerning Spearman's correlation coefficient between FHSQ subscales and FAOS and VAS. All domains of the FHSQ-NL, besides 'General health,' indicated good internal consistency with a Cronbach's alpha ranging from 0.61 to 0.91. Test-retest reliability of all FHSQ domains was poor with an ICC ranging from 0.47 to 0.77. At individual level, the SDC ranged from 35.1 to 60.6 and at a group level (n = 50) from 5.0 to 8.6. Construct validity was supported by confirmation of 75% of all a priori hypotheses. The FHSQ-NL has good internal consistency and smallest detectable change (SDC) at group level. However, reliability and SDC on individual level show suboptimal results. Therefore, the questionnaire is more suitable for evaluating foot complaints at group level instead of individual level.
我们研究的目的是开发荷兰语版的足部健康状况问卷（FHSQ-NL），并根据COSMIN定义（基于共识的健康测量工具选择标准）评估其测量属性。在翻译FSHQ之后，邀请了119名随机挑选的、因足部和踝关节疾病前往门诊就诊的患者参与研究，其中103名患者纳入分析。本研究使用FHSQ-NL、经过验证的荷兰语版FAOS以及疼痛和功能视觉模拟量表（VAS）作为结局指标。通过计算组内相关系数（ICC）评估信度，通过Cronbach's α评估内部一致性，并计算最小可检测变化（SDC）。通过使用关于FHSQ分量表与FAOS和VAS之间Spearman相关系数的先验假设来评估结构效度。FHSQ-NL除“总体健康”外的所有领域，Cronbach's α范围为0.61至0.91，表明具有良好的内部一致性。所有FHSQ领域的重测信度较差，ICC范围为0.47至0.77。在个体水平上，SDC范围为35.1至60.6，在组水平上（n = 50）为5.0至8.6。75%的先验假设得到证实，支持了结构效度。FHSQ-NL在组水平上具有良好的内部一致性和最小可检测变化（SDC）。然而，个体水平上的信度和SDC结果欠佳。因此，该问卷更适合在组水平而非个体水平上评估足部问题。
