SERVICE ACCESS AMONG INDIVIDUALS WITH PSYCHOTIC EXPERIENCES IN BANGKOK: RESULTS FROM THE 2023 THAI NATIONAL MENTAL HEALTH SURVEY
Keywords:
psychotic experiences, service utilisation, epidemiology, BangkokAbstract
Objectives: To investigate the lifetime and 12-month prevalence of psychotic experiences, patterns of service utilisation, and associated factors among individuals with psychotic experiences in Bangkok.
Material and Methods: Data were analysed from the 2023 Thai National Mental Health Survey, focusing on participants from Bangkok (n = 643). Data were collected between January and December 2023 using the Thai version of the World Health Organization-Composite International Diagnostic Interview version 3.0 (WHO-CIDI). Multivariate logistic regression examined the relationship between service utilisation and sociodemographic factors.
Results: The lifetime prevalence of psychotic-like experiences was 2.9% (95% CI: 1.3-4.5), while the 12-month prevalence was 0.9% (95% CI: 0.1-1.7). The service utilisation was 15.8% (95% CI: 5.5-37.6) for individuals with lifetime psychotic experiences and 16.7% (95% CI: 3.0-56.4) for those with 12-month psychotic experiences. Older adults (aged 60 and above) and individuals with an education below a bachelor's degree were significantly less likely to access services, whereas having comorbid psychiatric conditions was associated with higher service utilisation.
Conclusion: Service utilisation among individuals with psychotic experiences remains low, particularly among older adults and those with lower educational attainment. Tailored service systems must be developed to meet the specific needs of different ages and education groups.
