Cognitive dysfunction is one of the criteria for the diagnosis of fibromyalgia (FM) and is typically based on self-report questionnaires such as the Symptom Severity Scale. However, recent studies have shown that there is no correlation between these subjective measures of cognitive dysfunction and more lengthy objective measures of cognitive functioning. This points to the need for a briefer valid evaluation tool for cognitive dysfunction in FM. The aim of this study is to examine whether the Montreal Cognitive Assessment (MoCA) test is a valid measure of cognitive assessment in FM patients, by comparing it to a comprehensive computerised cognitive assessment battery.
Sixty-two FM patients (55 women, 7 men, mean age = 46.17 years, sd=12.56) were administered the MoCA and a computerised cognitive assessment battery. FM symptoms were assessed on the Fibromyalgia Impact Questionnaire (FIQ), the Widespread Pain Index (WPI), the Symptom Severity Scale (SSS), and the Beck Depression Inventory (BDI-2). Patient effort was controlled on the TOMM (Test of Memory Malingering).
Moderate positive correlations were found between the MoCA and the computerised cognitive scores as follows: Global Cognitive Score (r=0.493**, p=0.00), Memory Index Score (r= 0.384**, p=0.002), Executive Function Index Score (r=0.461**, p=0.00), Attention Index Score (r=0.310*, p=0.016), Information Processing Speed Index Score (r=0.435**, p=0.001), and Motor Skills (r=0.406**, p=0.002).
The MoCA is an acceptable cognitive screening test for the cognitive evaluation of FM patients.
认知功能障碍是纤维肌痛 (FM) 诊断标准之一，通常基于症状严重程度量表等自我报告问卷进行评估。然而，最近的研究表明，这些认知功能障碍的主观测量与更冗长的认知功能客观测量之间没有相关性。这表明需要一种更简短的纤维肌痛患者认知功能障碍的有效评估工具。本研究旨在通过与综合计算机认知评估电池进行比较，检验蒙特利尔认知评估 (MoCA) 测试是否是纤维肌痛患者认知评估的有效测量工具。
对 62 名纤维肌痛患者（55 名女性，7 名男性，平均年龄=46.17 岁，标准差=12.56）进行 MoCA 和计算机认知评估电池测试。纤维肌痛症状通过纤维肌痛影响问卷 (FIQ)、广泛性疼痛指数 (WPI)、症状严重程度量表 (SSS) 和贝克抑郁量表 (BDI-2) 进行评估。使用 TOMM（记忆错觉测试）控制患者的努力程度。
MoCA 与计算机认知评分之间存在中度正相关，如下所示：总体认知评分（r=0.493**，p=0.00）、记忆指数评分（r=0.384**，p=0.002）、执行功能指数评分（r=0.461**，p=0.00）、注意力指数评分（r=0.310*，p=0.016）、信息处理速度指数评分（r=0.435**，p=0.001）和运动技能（r=0.406**，p=0.002）。
MoCA 是纤维肌痛患者认知评估的一种可接受的认知筛查测试。
