The peer mental health stigmatization scale-revised (PMHSS-R): Psychometric properties and cross-cultural factorial invariance in university students in Ireland and Argentina.

Our findings highlight the PMHSS-R as a cross-culturally valid and reliable psychometric instrument to evaluate interventions targeting stigma. In conclusion, the PMHSS-R can be used in cross-cultural research to compare levels of mental health stigma and investigate the interplay between stigma and other psychologically relevant constructs between different countries and cultural contexts.
