Abstract Background Stigma is increasingly recognised as contributing to disability in MS. This systematic review aimed to answer the following question: To what extent is stigma associated with psychological and physical health outcomes in MS? Methods The inclusion criteria were: scientific publication of original quantitative research in adults with MS and/or Clinically Isolated Syndrome; outcome measures including a measurement of stigma and psychological and/or physical health; peer reviewed articles in the English language. Pubmed, PsycINFO and Science Direct were searched in November 2023. The Joanna Briggs Institute Critical Appraisal Tool was used to assess the methodological quality and risk of bias in all of the identified studies. The following data was extracted: (1) author and publication year, (2) country, (3) design, (4) sample size and demographics, (5) stigma measure, (6) psychological and/or physical health outcomes, 8) key findings. Results 18 Studies were identified, reporting in total 22,021 adult participants with multiple sclerosis, with individual sample sizes ranging from 33 to 6,670. The review consistently identified stigma to be significantly associated with adverse psychological and physical health outcomes in all 18 identified studies. Over half of all identified studies investigated depression and stigma and over half investigated quality of life and stigma, and a significant association was demonstrated for both of these variables with stigma in all of these studies. Discussion Limitations are that most studies were Western with primarily white participants. Only variables studied could be reported and therefore only a selective perspective of stigma in MS could be explored. A meta-analysis was not feasible, due to the variety of stigma definitions and measures employed. A model of stigma in MS is presented and possible interventions to manage stigma in MS are discussed. A need for international action to develop a consensus measure of MS stigma and determine the trajectory and causal dynamics of MS stigma is highlighted.
