. Selected aspects of the epidemiology of psychoses in Croatia, Yugoslavia. II. Pilot studies of communities. Amer J Epidem 94: 118125, 1971.The second in a three-part series reports the methodology and results of surveys on the prevalence of psychoses in four Croatian communities in Yugoslavia: Trogir, Sinj, Popova
a-Kutina, and Labin. The first three communities lie in the postulated "control" area while Labin is in the "study" area, hypothesized to have high prevalence rates. The rate in Labin is higher than the rate in Trogir and Sinj to a statistically significant extent. The difference remains significant when age is controlled and is primarily due to the "functional" psychoses (ICD codes 300303, Vllth revision). Since there is no evidence that Trogir, Sinj, and Popova
a-Kutina are typical of the whole of Croatia, and none that Labin is like the whole of the study area, these data are not represented as supporting the hypothesis of a higher prevalence of psychoses in the study area. A probability sample of Croatia, including both the study and control areas, is proposed as necessary to confirm that Croatia contains an area which has high prevalence rates for psychosis and to define the limits of the high rate area, if proven to exist.
