The purpose of this study was to investigate the impact of an intervention designed to support newly diagnosed primary brain tumour patients. The intervention involved a structured, one time meeting between newly diagnosed patients and trained volunteer “veteran” primary brain tumour patients. Methods Two trained volunteers met for a single, face to face meeting on an individual basis with a total of 10 newly diagnosed patients. A combination of questionnaires and interviews were used to investigate the impact of the intervention for the new patients and the volunteers. Results: The intervention appeared to be of substantial value for both groups of participants. Analysis revealed that the newly diagnosed patients experienced a range of benefits, including those related to the themes of: increased hope; valued guidance; hearing what it’s really like; overcoming aloneness; and realignment of priorities. Veteran patients experienced a sense accomplishment and decreased anxiety as a result of the intervention. Only minor adverse effects and challenges were reported. Conclusions The findings provide initial evidence that the experimental intervention has the potential to be a safe, effective means of promoting psycho-social well-being in newly diagnosed patients and may also have positive effects for veteran patients. Further investigation into the use of one to one, peer support for brain tumour patients is an important research priority.
