Objective:
To determine whether the stigma associated with schizophrenia has also been directed towards people at ultra-high risk of psychosis (UHR), the present review aimed to synthetize the literature to update and extend our understanding of this topic.
Methods:
A systematic review compliant with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted in the PubMed, EMBASE, Cochrane, and Web of Science databases for articles published until April 30, 2023, using a combination of search terms describing at-risk mental states for psychosis, stigma, and related terms.
Results:
Thirty-eight studies were included. Twenty-nine addressed individuals with UHR directly, and nine conducted interviews with non-patients regarding UHR. A total of 2,560 individuals with UHR were assessed, with a mean sample size of 88.3 participants. Most were quantitative non-randomized/observational studies with young adults, 71.4% used the Structured Interview for Psychosis-Risk Syndromes, and 25% used the Comprehensive Assessment of At-Risk Mental States. Overall, the studies mainly involved patients of UHR clinics from high-income Western countries. The described stigma can be grouped into five forms, the most frequently explored of which was perceived public stigma, followed by public stigma, self-stigma/internalized stigma, stigma stress, and associative stigma. Quantitative nonrandomized studies predominated: only one was an interventional study. Most of the results confirmed the presence of stigma toward individuals with UHR.
Conclusion:
Despite the knowledge gaps and scarcity of research on UHR-related stigma, the results suggest that stigma toward people with UHR exists and that it is already present at early stages of psychosis.
