Study of the relationship between adherence to back school and coping with pain in patients with chronic low back pain. Back School (BS) is a treatment modality for patients with chronic low back pain with educational contents associated with other therapeutic measures such as exercise. If followed, it is effective but it is well known that it is difficult to make changes to daily habits. This study evaluated whether patients completing BS had a predominance of active strategies in coping with pain, as they adhered better to the recommendations of BS. Material and method. Prospective observational study to evaluate BS adherence in patients with chronic low back pain. Adult patients attending BS were included in the study. Patients whose educational level, concomitant pathology or personal situation prevented them from completing the study were excluded. The patients were evaluated at the beginning and after the third session of BS. The variables studied were adherence to exercises and recommendations, coping with pain, pain intensity, functional disability and other sociodemographic characteristics. Results. A total of 67.2% of the 116 included patients acknowledged that they did not perform the exercises and recommendations of BS every day. No relationship was established between patients with active strategies for coping with pain and adherence to BS. Functional capacity and pain intensity did not differ between adherent and non-adherent patients. Conclusions. This study did not demonstrate that adherence to the exercises and habits taught in BS is related to coping with pain strategies, pain intensity and functional capacity in patients with chronic low back pain.
