We sampled 419 primary school children by using a one-stage design in Izmir, Turkey. The response rate was 99.5 % and 417 cases were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime Version and a scale to assess the impairment criterion. The results showed that 36.7 % of the sample met DSM-IV criteria independent of impairment and that 14.1 % of the population had one or more DSM-IV disorders when a measure of impairment specific to each diagnosis was considered. The most prevalent disorders were attention-deficit/hyperactivity disorder and anxiety disorders. This study provided the first estimates of the prevalence of specific DSM-IV-defined psychiatric disorders in Turkish population of children.en10.1007/s10578-015-0541-3info:eu-repo/semantics/closedAccessChildrenPsychiatric disordersEpidemiologyPrevalenceImpairmentArticle4713542WOS:00036818140000425846701Q2
