Abstract: (8 Views)
Aim and background: Fibromyalgia syndrome is a chronic musculoskeletal pain condition characterized by widespread pain, sleep disturbances, fatigue, cognitive difficulties, and emotional challenges. The aim of the present study was to investigate the role of chronic pain acceptance, pain catastrophizing, and sleep quality in predicting working memory performance in individuals with fibromyalgia.
Material and Method: The present research is applied in terms of purpose and descriptive in terms of method, of the correlational (regression) type. The statistical population consisted of patients with fibromyalgia who visited private offices, from which 100 were selected non-randomly and purposefully. Data were collected through the Chronic Pain Acceptance Questionnaire (P-CPAQ), the Pain Catastrophizing Scale (PCS), the Pittsburgh Sleep Quality Index (PSQI), and the Wechsler Working Memory Test (WAIS-IV). The data were then analyzed using SPSS software version 27 and generalized linear regression (GLM).
Results: The results of the Spearman's correlation test with a significance level of 0.05 showed no significant relationship between chronic pain acceptance (r = -0.078, p-value = 0.768), pain catastrophizing (r = -0.152, p-value = 0.289), and sleep quality (r = -0.175, p-value = 0.114) with working memory performance. The GLM model also did not confirm any significant effect of these variables on working memory performance.
Conclusion: Based on the results of the present study, it is suggested that other factors, such as neuroinflammation or mood disorders, may play a more prominent role in the cognitive impairments of these patients.
