Positive Mental Training in patients with Multiple Sclerosis experiencing psychological distress: A Preliminary Randomised Controlled Trial

IntroductionPsychological distress is a major issue in multiple sclerosis (MS), having a significant impact on quality of life. Antidepressants are generally unhelpful for subsyndromal symptomatology, and psychological treatment approaches often not accessible or too cognitively demanding for some patients. There is an urgent need for low-cost interventions to improve wellbeing in MS. MethodsThis was a pilot randomised controlled trial (RCT) of Positive Mental Training (PosMT), a low intensity intervention providing training in positivity, optimism and resilience previously shown to improve anxious and depressive symptomotology. 28 patients with MS were randomised to the intervention and 30 to the control group. ResultsFollow-up data was obtained from 39 patents. The majority of participants receiving PosMT reported that they had used the intervention, with few reporting side effects. The intervention group reported a significant improvement in self-rated health as measured by the EuroQual visual analogue scale, F(4,34) = 3.204, p = 0.025, R2 = 0.274. DiscussionThis preliminary RCT found that PosMT in its current form could be used by patients with MS with little difficulty. Despite the small size of the study, allocation to the intervention was found to be associated with a significant improvement in self-rated health. Given the low cost of PosMT and its easy availability (it can simply be downloaded from a website), this pilot RCT suggests it could be a useful tool for MS patients. We believe this intervention warrants further study, ideally in a large multi-centre RCT.
