Epidemiological Study of the Prevalence of Mental Disorders in the Population of the Slovak Republic

Examining the current prevalence of mental disorders in the Slovak population will allow for the accurate identification of population groups who, despite experiencing symptoms of mental disorders, do not utilize mental health care services. As a result, these individuals often experience reduced functionality and a diminished quality of life. According to expert estimates, this group may include 60-80% of people with symptoms of mental disorders. However, only a population-based study that comprehensively maps this issue can provide a clear and accurate picture of the situation.

This survey on the prevalence of mental disorders and their associated risk factors will be conducted as a cross-sectional study using the internationally recognized and standardized Mini International Neuropsychiatric Interview (MINI).

The MINI instrument will be administered first to 100 respondents in a pilot phase and then to a representative sample of 3,000 respondents. Participants will be selected using a multistage sampling method that covers the entire adult population of the Slovak Republic. The selection process and data collection will be conducted by a professional research agency.

The sample size has been carefully calculated to ensure that the results are generalizable to the entire adult population of Slovakia, with a 95% confidence interval and a 2% margin of error. This representative sample will make it possible to gather sufficient data even on the least common mental disorders (with a prevalence of around 1%), ensuring that the findings are both meaningful and statistically robust.

Data collection will take place through face-to-face interviews conducted by trained interviewers from the research agency, all of whom will receive specialized training in administering the MINI tool. The data will then be subject to in-depth analysis and interpretation by experts in epidemiology, clinical psychology, sociology, and psychiatry. This multidisciplinary evaluation will serve as the foundation for developing recommendations for key ministries - including those responsible for health, education, family, and social affairs - as well as for other sectors of society. The results will also be internationally comparable, as they will align with data collected using the same methodology in other countries.
