The frequency of experienced discrimination was reported. Scaling assumptions (confirmatory factor analysis, inter-item and item-total correlations), reliability (internal consistency) and validity (convergent validity, known groups method) were investigated in each region, and by diagnosis group.<h4>Results</h4>1195 peoplePsychological medicine1-11https://www.ebi.ac.uk/biostudies/studies/S-EPMC10317801biostudies-literatureMeasuring discrimination experienced by people with a mental illness: replication of the short-form DISCUS in six world regions.PMC10317801Thornicroft GLanfredi MOchoa SChang CCSchomerus GSportel BEKlemm PYalcınkaya-Alkar OUcok AFadipe BShanthi COexle NSebes JCastelein SBakolis ISampogna GLi JTomas CPaula CSValverde LCampbell MMRusch NEvans-Lacko SFiorillo AAlexova AOuali UReneses BLasalvia AGuimaraes PNBrohan EfalseMeasuring discrimination experienced by people with a mental illness: replication of the short-form DISCUS in six world regions.<h4>Background</h4>The Discrimination and Stigma Scale (DISC) is a patient-reported outcome measure which assesses experiences of discrimination among persons with a mental illness globally.<h4>Methods</h4>This study evaluated whether the psychometric properties of a short-form version, DISC-Ultra Short (DISCUS) (11-item), could be replicated in a sample of people with a wide range of mental disorders from 21 sites in 15 countries/territories, across six global regions.
