In this study, 54 patients suffering from chronic cervicobrachialgia (mean pain duration 7 years) were treated with radiofrequency lesioning of the cervical spinal dorsal root ganglion (RF‐DRG). The aim of the study was to investigate whether psychological variables would be predictive for the changes in pain intensity after medical treatment. The following psychological aspects were measured: pain cognitions, negative self‐efficacy and catastrophizing, physical and psychosocial dysfunction, and overall distress. The level of catastrophizing before treatment appeared to predict 10% of the changes in pain intensity after treatment. Changes in pain intensity after RF‐DRG were positively correlated with changes in psychosocial dysfunction and negative self‐efficacy.
