Validity and Reliability of Arabic Version of Extended Aberdeen Spine Pain Scale

The goal of this observational study is to determine whether the Arabic version of the Extended Aberdeen Spine Pain Scale (EASPS) is a valid and reliable tool for assessing spine-related pain and functional disability in Arabic-speaking adults with nonspecific spinal pain. The main questions it aims to answer are: * Is the Arabic version of the EASPS a valid instrument for evaluating spine-related pain and disability among Arabic-speaking patients? * Is the Arabic version of the EASPS a reliable instrument with acceptable internal consistency and test-retest reliability? Participants will: * Complete the Arabic version of the Extended Aberdeen Spine Pain Scale (EASPS). * Complete the Arabic version of the Short Form-36 (SF-36) questionnaire to assess construct validity. * Participate in the cultural adaptation and validation process of the Arabic EASPS. * A subgroup of participants will complete the Arabic EASPS again after 7 days to assess test-retest reliability.
