Using a cross-sectional design study, they were assessed for psychiatric disorders by the Self Rating Questionnaire (SRQ), the Clinical Interview Schedule/revised (CIS-R), and the W.H.O Audit Instrument for Alcohol abuse.

The findings were that the overall prevalence rate of psychiatric disorder was 0.43% with an incidence of 0.43% per 1000 persons.
