Abstract：
Brain fog is a condition that is characterized by poor concentration, memory loss, decreased cognitive function, and mental fatigue. Although it is generally known as a long-term COVID-19 symptom, brain fog has also been reported to be caused by many other diseases. Thus, it is necessary to assess this condition in certain populations. This study aimed to evaluate the reliability and validity of the Brain Fog Scale in a Turkish population. We conducted the study in two phases. In a pilot study including 125 participants, we confirmed the suitability of the scale for validity analyses and then conducted exploratory (n = 230) and confirmatory factor analyses (n = 343). The Cronbach\'s alpha value of the 23-item Brain Fog Scale was 0.966. In addition, the 23-item and three-factor structure was confirmed as a result of the analyses. These three factors are mental fatigue, impaired cognitive acuity, and confusion. We also found that participants previously diagnosed with COVID-19 had higher brain fog scores. This finding indicates that brain fog is an important condition that can accompany COVID-19. Furthermore, this validated construct has an acceptable fit and is a valid and useful tool for the Turkish population.
摘要：
脑雾是一种以注意力不集中为特征的疾病，记忆丧失,认知功能下降，和精神疲劳。虽然它通常被称为一种长期的COVID-19症状，据报道，脑雾也是由许多其他疾病引起的。因此，有必要在某些人群中评估这种情况。这项研究旨在评估土耳其人群脑雾量表的信度和效度。我们分两个阶段进行了研究。在一项包括125名参与者的试点研究中，我们确认量表适用于有效性分析,然后进行探索性(n=230)和验证性因素分析(n=343).23项脑雾量表的Cronbachα值为0.966。此外,分析结果证实了23项和三因素结构.这三个因素是精神疲劳，认知敏锐度受损，和困惑。我们还发现，先前被诊断患有COVID-19的参与者的脑雾评分更高。这一发现表明，脑雾是可能伴随COVID-19的重要疾病。此外，这个经过验证的结构具有可接受的拟合度,是土耳其人口的有效和有用的工具.
