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.
