To validate a translated version of the Fibromyalgia Impact Questionnaire (FIQ) to be used by Hebrew speaking populations.
We administered the FIQ to 100 women with fibromyalgia (FM). The FIQ measures physical functioning, work status, depression, anxiety, sleep, pain, stiffness, fatigue, and well being. All patients were asked about the presence and severity (assessed by visual analog scale) of relevant FM symptoms (pain, fatigue, anxiety, etc.); a count of 18 tender points was conducted by thumb palpation, and tenderness thresholds were assessed by dolorimetry. Test-retest reliability was assessed using Spearman correlations. Internal consistency was evaluated with Cronbach's alpha coefficient of reliability. To assess content validity a cutoff criterion of > or = 25% impairment responses was set to indicate a valid item. Construct validity of the FIQ was evaluated by correlating the physical functioning score as well as the separate items with measures of symptom severity, count of tender points, and tenderness thresholds.
Test-retest reliability was r = 0.96 for physical functioning, and 0.80-0.96 for other items of FIQ. Internal consistency was alpha = 0.93 at Time 1 and 0.86 at Time 2. Seventeen of 19 items of the FIQ met the > or = 25% criterion. Significant moderate to high correlations were obtained between the FIQ items and severity symptoms, point count, and tenderness threshold.
The FIQ is a reliable and valid instrument for measuring functional disability and health status in Israeli women with FM.
验证供说希伯来语人群使用的纤维肌痛影响问卷（FIQ）的翻译版本。
我们对100名纤维肌痛（FM）女性患者进行了FIQ问卷调查。FIQ评估身体功能、工作状态、抑郁、焦虑、睡眠、疼痛、僵硬、疲劳和幸福感。所有患者均被询问相关FM症状（疼痛、疲劳、焦虑等）的存在情况及严重程度（通过视觉模拟量表评估）；通过拇指触诊计数18个压痛点，并使用痛觉计评估压痛阈值。采用Spearman相关性评估重测信度。用Cronbach's α信度系数评估内部一致性。为评估内容效度，设定≥25%损伤反应的截断标准以表明项目有效。通过将身体功能得分以及各个项目与症状严重程度测量值、压痛点计数和压痛阈值进行相关性分析，评估FIQ的结构效度。
身体功能的重测信度r = 0.96，FIQ其他项目的重测信度为0.80 - 0.96。内部一致性在第一次测量时α = 0.93，第二次测量时α = 0.86。FIQ的19个项目中有17个符合≥25%的标准。FIQ项目与症状严重程度、点数计数和压痛阈值之间存在显著的中度到高度相关性。
FIQ是测量以色列FM女性功能残疾和健康状况的可靠且有效的工具。
