SUMMARY:

Introduction: Fibromyalgia is a chronic, multifactorial condition characterized by widespread nociplastic pain and associated symptoms that affect functionality and quality of life, predominantly among women. Among the psychosocial factors that modulate chronic pain, pain catastrophizing stands out, characterized by the presence of negative thoughts and associated feelings of helplessness. Objective: To analyze pain catastrophizing in women with fibromyalgia based on contextual factors, such as pain interference with daily activities, sleep quality, monthly income, and time since diagnosis. Methods: This was a cross-sectional, quantitative, descriptive observational study conducted with 82 women at the Physical Therapy Teaching Clinic of the Federal University of Rio Grande do Norte, Brazil. Data were collected using a sociodemographic questionnaire developed by the researchers, the Brief Pain Inventory, the Pittsburgh Sleep Quality Index, and the Pain Catastrophizing Scale. Data were analyzed using descriptive statistics and multiple linear regression. Results: High levels of pain catastrophizing, significantly poor sleep quality, and moderate to severe pain were observed, with substantial interference with work and sleep. The following variables showed statistical significance as predictors of pain catastrophizing: pain interference (β = 0.292), pain catastrophizing (β = 0.396), sleep quality (β = 0.351), monthly income (β = −0.249), and time since fibromyalgia diagnosis (β = −0.176). The multiple linear regression model yielded an adjusted R² of 0.456, with satisfactory goodness-of-fit measures and no evidence of multicollinearity. Poorer sleep quality and greater pain interference were positively associated with pain catastrophizing, whereas higher income and longer time since diagnosis were negatively associated with it. Conclusions: Pain catastrophizing was prevalent among women with fibromyalgia who presented poor sleep quality and a negative impact on quality of life. Regarding protective factors associated with lower levels of pain catastrophizing, better socioeconomic conditions and a longer time since fibromyalgia diagnosis stood out.
