Input: Two small studies (enrolling a total of 105 participants) met the inclusion criteria. One was a standard cognitive behavioural treatment (CBT) programme for 61 people with pain from spinal cord injury, followed up for three months, and compared with a waiting list. The other was weekly group psychotherapy for 44 people with burning mouth syndrome, compared with a daily placebo tablet. The overall risk of bias was high in both trials. The CBT study assessed participants for pain, disability, mood, and quality of life, with improvement in treatment and control groups. However, there was no more improvement in the treatment group than in the control for any outcome, either post-treatment or at follow-up. The group psychotherapy study only assessed pain, classifying participants by pain severity. There is a lack of evidence on the efficacy and safety of psychological interventions for people with neuropathic pain. There is insufficient evidence of the efficacy and safety of psychological interventions for chronic neuropathic pain. The two available studies show no benefit of treatment over either waiting list or placebo control groups.
Output:

Our confidence in the results of the individual trials was limited by several potential biases in how they were conducted. We were not able to analyse the results of the two trials together because the experiences of people with spinal cord injury or burning mouth are too different from each other. On their own, the trials were too small for us to undertake any statistical analysis. However, neither trial found any clear benefit of treatment. We conclude that there is currently no evidence that will help practitioners and patients to decide whether to use these treatments. We discuss what studies are needed.
