Abstract

Background: Psychotic symptoms, psychotic-like experiences and schizotypal signs can emerge in different socio-cultural circumstances and cause clinical or non-clinical pictures. Transient or self-limiting psychotic-like experiences are more prevalent than clinical psychotic disorders. The aim of this study is to determine the prevalence and sociodemographic correlates of psychotic symptoms in an urban area.

Methods: A cross-sectional study was conducted among the residents of two districts in the urban area of Izmir, Turkey. Among the systematically selected 1,500 residents of 85,212-study population, a total of 1,268 individuals (response rate: 84.5%) were screened for any lifetime psychotic symptoms.

Results: Composite International Diagnostic Interview (CIDI) was used to assess psychotic symptoms. CIDI (+) psychotic symptoms were found in 3.6% of the screened sample. Logistic regression analysis showed that being a female (OR=2.4, 95% CI=1.2-5.1), having a first degree family history of any mental disorders (OR=13.9, 95% CI=5.7-34.3), lack of social support (OR=4.5, 95% CI=2.3-8.6) and alcohol use (OR=4.9, 95% CI=2.3-10.6) were all related to psychotic symptoms.

Conclusion: Prevalence of any psychotic symptom is lower compared to European studies. Alcohol might be considered as a risk factor for developing psychotic symptoms in the Turkish cultural setting.
