Prevalence of DSM-III-R and ICD-10 psychiatric disorders in a Spanish population of 18-year-olds

Abstract

The aim of this study was to estimate the current prevalence of DSM-III-R and ICD-10 psychiatric disorders in Spanish 18-year-old members of the general population. Subjects were assessed using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Nearly 30% of the study subjects reported at least one current disorder according to ICD-10 criteria, and almost 21% reported at least one current disorder according to DSM-III-R criteria. Women had a significantly higher probability of suffering from any psychiatric disorder than men. The most common disorders were insomnia, dysthymia, major depression and simple phobia. Nearly 40% of the diagnosed subjects had one or more comorbid disorders. Comorbidity was found to be higher among female subjects. Consistent with previous risk factor research, it was found that women had higher rates of mood, anxiety and sleep disorders than men. Good communication between parents and their offspring was found to be a protecting factor for all disorders.
