Objectives：The aim of this study was to investigate the lifetime prevalence of psychotic experiences (PEs) and the association of PEs with a range of psychiatric disorders in the Korean general population.
Methods：Multi-stage cluster sampling was adopted in this study. Interviews were conducted face-to-face with 18-year-old and older people living in the community from June to November 2016. Korean version of Composite International Diagnostic Interview (K-CIDI) was applied to assess the prevalence of psychiatric disorders. Psychotic experiences were assessed with 21 items (15 items for hallucinations and 6 items for delusions) in the CIDI psychosis module.
Results：Mean lifetime prevalence (standard error) of ever having a PEs was 3.3% (0.3) with 2.2% (0.2) of hallucinatory experiences and 1.7% (0.2) of delusional experiences. The lifetime prevalence of PEs was higher in young people and in persons with unemployment or part-time-job. PEs were associated with an increase in the lifetime prevalence of anxiety disorders [Adjusted odd ratio (AOR)=6.3 ; p<0.001], mood disorders (AOR=4.9 ; p<0.001), alcohol use disorders (AOR=2.4 ; p<0.001), and nicotine use disorders (AOR=2.4 ; p<0.001) after controlling for sociodemographic variables.
Conclusion：PEs are related to various non-psychotic disorders as well as psychotic disorders. Clinicians should pay more attention to the mental health of individuals with PEs.
