Delusional beliefs and experiences can predict the development of mental disorders within the spectrum of psychosis. The nature, content and prevalence of delusional experiences in the general population are still disputed topics. This study investigates the latent structure of delusion proneness in the non-clinical population. Eight hundred young adults (400 from Italy and 400 from the United Kingdom) completed the Peters et al. delusions inventory, a general population measure of delusional proneness. Latent class analysis was used to explore the latent structure of delusion proneness. Four classes were identified: low delusion proneness (including 28% of the sample), grandiosity (13%), paranoid thinking (41%) and positive psychotic beliefs (18%). Latent structures of sub-clinical symptoms can be observed also in non-clinical population; paranoid thinking is the most common delusional theme.
