Summary: Neuropsychological assessment (NPA) feedback is believed by many to be beneficial to patients, yet there is a paucity of scientific evidence supporting this belief, and conversely there is evidence that there are risks associated with providing “bad news” in particular. We ran a randomised controlled trial to investigate the psychological benefits of NPA feedback vs "sham wait-list control" using a sample of 71 patients with multiple sclerosis (MS). The results showed that there were no significant changes in the psychological status of patients one week after feedback. Importantly, there were no significant reductions in psychological wellbeing, despite most of the patients receiving “bad news” confirming at least some degree of cognitive impairment. Satisfaction ratings of the NPA with feedback experience were high. Furthermore, one month later patients showed significant improvements in their perceived level of cognitive functioning, MS self-efficacy, and mood. These results provide evidence that NPA feedback is a relatively safe and effective psycho-educational intervention in MS.
