The goal of this observational cross-sectional study is to learn about the intensity of anxiety symptoms among Polish people suffering from chronic lower back pain. The main question it aims to answer is: What is the severity of anxiety symptoms among the Polish population of patients suffering from chronic lower back pain?

Chronic low back pain (CLBP) is among the most prevalent musculoskeletal disorders and is one of the leading causes of disability worldwide. Epidemiological data indicate that while most individuals will experience low back pain at some point in their lives, approximately 10-20% of these cases evolve into chronic conditions lasting longer than three months. The burden of CLBP extends beyond physical symptoms, as it is frequently associated with psychological comorbidities, most notably anxiety disorders. The biopsychosocial model of pain highlights the interrelated role of biological, psychological, and social factors in shaping the patient's pain experience and functional outcomes. Anxiety symptoms have been consistently identified as amplifiers of pain perception, contributors to disability, and predictors of poor treatment response. Despite international evidence documenting high rates of anxiety in CLBP populations, there is a paucity of data from Poland. This study therefore aims to evaluate the severity of generalized anxiety symptoms in a Polish cohort of patients with CLBP and to investigate sociodemographic and clinical factors potentially associated with anxiety severity. The study was designed as a cross-sectional observational investigation, conducted at the NZOZ REHABMED-I rehabilitation clinic in Katowice, Poland. Participants were adults aged 18 years or older, with CLBP persisting longer than three months, fluent in Polish, and willing to provide informed consent. Exclusion criteria included recent spinal trauma or surgery, severe psychiatric illness, and pregnancy in the past year. A total of 202 participants were recruited, surpassing the required minimum calculated sample size (n = 196). Data collection involved completion of the Generalized Anxiety Disorder 7-item scale (GAD-7), supplemented with questions on demographics, pain duration, and comorbidities. Statistical analyses included descriptive summaries, Pearson correlations, independent-sample t-tests, and one-way ANOVA to evaluate associations between anxiety severity and age, gender, education, work type, pain duration, and comorbidities. Preliminary results demonstrated that nearly half of participants reported clinically relevant anxiety (mild to severe). Comorbidities emerged as the most robust correlate of higher anxiety scores, while gender, education, work type, and pain duration did not show significant associations. These findings highlight the importance of integrating psychological screening into the management of CLBP, particularly for patients with comorbid conditions. The study contributes to growing international evidence that CLBP should be addressed through a biopsychosocial approach, where both physical and psychological dimensions are routinely assessed and treated. Implementation of targeted interventions such as cognitive-behavioral therapy and acceptance-based strategies may improve outcomes, reduce disability, and enhance quality of life in this patient population.
