The Revised version of the Fibromyalgia Impact Questionnaire (FIQR) was published in 2009. The aim of this study was to prepare a Spanish version, and to assess its psychometric properties in a sample of patients with fibromyalgia.
The FIQR was translated into Spanish and administered, along with the FIQ, the Hospital Anxiety Depression Scale (HADS), the 36-Item Short-Form Health Survey (SF-36), and the Brief Pain Inventory (BPI), to 113 Spanish fibromyalgia patients. The administration of the Spanish FIQR was repeated a week later.
The Spanish FIQR had high internal consistency (Cronbach’s α was 0.91 and 0.95 at visits 1 and 2 respectively). The test-retest reliability was good for the FIQR total score and its function and symptoms domains (intraclass correlation coefficient (ICC > 0.70), but modest for the overall impact domain (ICC = 0.51). Statistically significant correlations (p < 0.05) were also found between the FIQR and the FIQ scores, as well as between the FIQR scores and the remaining scales’ scores.
The Spanish version of the FIQR has a good internal consistency and our findings support its validity for assessing fibromyalgia patients. It might be a valid instrument to apply in clinical and investigational grounds.
纤维肌痛影响问卷（FIQR）的修订版于 2009 年发布。本研究旨在编制一份西班牙语版本，并在纤维肌痛患者样本中评估其心理测量特性。
FIQR 被翻译成西班牙语，并与 FIQ、医院焦虑抑郁量表（HADS）、36 项简短健康调查问卷（SF-36）和简明疼痛量表（BPI）一起，对 113 名西班牙纤维肌痛患者进行评估。一周后，再次进行西班牙 FIQR 的评估。
西班牙 FIQR 具有较高的内部一致性（第 1 次和第 2 次就诊时 Cronbach's α 分别为 0.91 和 0.95）。FIQR 总分及其功能和症状领域的重测信度良好（组内相关系数（ICC > 0.70），但总体影响领域的重测信度中等（ICC = 0.51）。FIQR 与 FIQ 评分之间，以及 FIQR 评分与其余量表评分之间也存在显著的相关性（p < 0.05）。
FIQR 的西班牙语版本具有良好的内部一致性，我们的研究结果支持其用于评估纤维肌痛患者的有效性。它可能是一种在临床和研究中应用的有效工具。
