The purpose of this study is to evaluate the influence of coping strategies and catastrophizing thoughts on disability and the prognosis of back and neck pain in patients treated within the Spanish National Health Service. Patients will be given a visual analog scale (VAS) to rate intensity of pain, the Roland Morris Questionnaire (RMQ) or the Neck Disability Index (NDI) to rate the degree of disability, and the Coping Strategies Questionnaire (CSQ) to rate coping strategies and catastrophizing. Questionnaires will be given at baseline and three months later.
