Brief summary

This study aims to translate, culturally adapt, and psychometrically validate the Persian version of the Cognitive Behavioral Questionnaire in Nonspecific Chronic Low Back Pain (CBQ-NSCLBP). The process will follow standard cross-cultural adaptation guidelines, including forward-backward translation, expert review, and pilot testing. The psychometric properties, including internal consistency, test-retest reliability, and construct validity, will be evaluated in a sample of Persian-speaking adults with nonspecific chronic low back pain.

Detailed description

Chronic low back pain (CLBP) is a common and persistent musculoskeletal condition that affects a large portion of the population and can lead to long-term disability. It is typically defined as pain in the lower back that lasts for more than 12 weeks and often impacts daily function and quality of life. In addition to physical symptoms, people with CLBP frequently experience cognitive and behavioral challenges, such as fear-avoidance beliefs, catastrophizing, and difficulty concentrating. These factors can contribute to ongoing disability and interfere with the rehabilitation process. The Cognitive Behavioral Questionnaire for Nonspecific Chronic Low Back Pain (CBQ-NSCLBP) was developed to assess these cognitive-behavioral aspects in people with nonspecific CLBP. However, it has only been validated in one population and has not yet been adapted for Persian-speaking individuals. This study aims to translate and culturally adapt the CBQ-NSCLBP into Persian and evaluate its psychometric properties in individuals with nonspecific chronic low back pain
