COVID-19-related stigmatization of affected people or people at risk of infection has been shown to enhance the reluctance of affected individuals to use health services and reduce their mental health. It is thus highly important to gain a thorough understanding of COVID-19-related stigmatization. The present study’s first aim was to explore stigmatization profiles of experienced stigmatization (anticipated stigmatization, internalized stigmatization, enacted stigmatization, disclosure concerns) and stigmatization practices in 371 German people at high risk of infection using latent class analyses. The second aim was to investigate the relationship between stigmatization profiles and psychological distress via multiple regression analysis taking into account other possible negative and positive risk factors. Our results showed two stigmatization profiles: "high stigmatization group" and "low stigmatization group". Belonging to the "high stigmatization group" was significantly correlated with higher levels of psychological distress. Other risk factors significantly related to psychological distress were mental health disorders in the past, exposure to COVID-19, fear related to COVID-19, perceived risk of being infected, lower perceived self-efficacy, and lower subjective knowledge about COVID-19.
