ABSTRACT
Ob­jec­ti­ve: In recent years, interest on prevalence and comorbidity of impulse control disorders is constantly increasing. The aim of this study was to investigate the prevalence of impulse control disorders and its association with the existence of comorbid axis I disorders in young adult university exam preparatory course students. Met­hods: Two hundred and twenty-six preparatory course students aged 18-27 (mean age: 19.2) years were included in this study. Axis I diagnoses were evaluated using the Structured Clinical Interview for DSM-IV (SCID-I). Lifetime impulse control disorders were investigated using the modified version of Minnesota Impulsive Disorders Interview. Impulsivity was measured with the Barratt Impulsiveness Scale Version 11(BIS-11).Re­sults: The prevalence rate of all impulse control disorders in our sample was 23.4% (n=55). The most common impulse control disorder subtype was impulse control disorder not otherwise specified ICD-NOS (%16.8), followed by trichotillomania and intermittent explosive disorder. The most common ICD-NOS subtype was compulsive buying. There was no statistically significant difference between the diagnoses of axis I disorders in students with and without impulse control disorders. A statistically significant difference was found between groups with and without impulse control disorders in terms of total impulsivity and non-planning scores determined by the BIS-11. Conc­lu­si­on: Considering early age onset and decreasing prevalence with progressive aging, impulse control disorders are expected to be common in the young adult population. Prevalence rates determined at the end of this study were found to be higher in comparison with the peer group in literature. However, the prevalence rates obtained in our study may not be generalized tothe society because of the statistical limitation concerning our sample size. Large-scale, epidemiologic studies are required to be performed on this topic. (Arc­hi­ves of Neu­ropsy­chi­atry 2011;48: 238-42)
