本研究的目的是评估纤维肌痛调查问卷（FSQ）和多症状痛苦量表（PSD）在伊朗人群中的有效性。我们还试图根据 PSD 量表对纤维肌痛 (FM) 症状的严重程度进行分类。根据专家医师的诊断，参与者被分为 FM 和非 FM 慢性疼痛障碍组。两组患者均回答波斯语翻译版 FSQ、纤维肌痛影响问卷 (FIQ) 和 Short-Form-12 (SF-12)。 1990 年 ACR 标准和 FSDC 对两组参与者进行了评估。评估了内部一致性和结构效度。通过 Cronbach's alpha 测量得出的内部一致性良好（FSQ 为 0.814）。 FSQ 及其分量表与 FIQ 分数和 SF-12 分量表显着相关，表明结构效度可接受。 FSQ与1990年ACR标准和专家诊断的一致率分别为61.2和75.7（收敛效度）。 FM 组的 PSD 平均分及其组成部分显着高于对照组（区分效度）。使用较低的 PSD 分数截止值（千分之 8.5）来诊断纤维肌痛似乎是我们人群中最有效的方法。 PSD 评分的 ROC 分析显示，8.5-11.5、11.5-15 和 15 以上分别为轻度、中度和重度 FM。波斯语版本的 FSQ 是伊朗慢性疼痛疾病患者调查研究的有效工具。目前的研究表明，无论纤维肌痛诊断如何，PSD 都可以用作评估症状强度的有效工具。
The aim of this study was to assess validity of the fibromyalgia survey questionnaire (FSQ) and polysymptomatic distress scale (PSD) in an Iranian population. We also sought to classify the severity levels of fibromyalgia (FM) symptoms according to the PSD scale. Participants were divided into FM and non-FM chronic pain disorder groups according to expert physician diagnosis. Patients in both groups answered to Persian-translated version of FSQ, fibromyalgia impact questionnaire (FIQ) and Short-Form-12 (SF-12). Both 1990 ACR criteria and FSDC were assessed in participates of two groups. Internal consistency and construct validity were evaluated. There was good internal consistency measured by Cronbach's alpha (0.814 for FSQ). FSQ and its subscales correlated significantly with FIQ scores and SF-12 subscales, indicating acceptable construct validity. The concordance rates of FSQ with 1990 ACR criteria and expert diagnosis were 61.2 and 75.7, respectively (convergence validity). The mean score of PSD and its components in FM group were significantly more than in control groups (discriminative validity). Using lower PSD score cutoff (a parts per thousand yen8.5) for the diagnosis of fibromyalgia appeared to be the most effective approach in our population. ROC analysis of the PSD scores revealed 8.5-11.5, 11.5-15 and more than 15, respectively, as a mild, moderate and severe FM. Persian version of FSQ was a valid instrument for application in survey research among Iranian patients with chronic pain disorders. The current study revealed that PSD could be used as a valid tool for assessment of symptoms intensity regardless of fibromyalgia diagnosis.
