The purpose of this study was to examine the utility of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) in detecting OCD in African Americans when used by well-trained, culturally competent clinicians. METHODS Seventy-four Af...

This study investigated the neurocognitive correlates of childhood OCD and TS, which are purported to share frontal-striatal dysfunction. Neurocognitive measures tapping frontal-striatal functions such as executive, attention/memory, and visuomotor abilities were administered to three groups of participants, OCD without comorbid TS (OCD), TS without comorbid OCD (TS), and normal controls. Resul...

INTRODUCTION Major depressive disorder (MDD) is the most frequent comorbid psychiatric condition associated with obsessive-compulsive disorder (OCD). This study aimed to evaluate the prevalence of current depression in OCD, differences in socio-demographic and clinical characteristics, and obsessive-compulsive symptoms between OCD patients with and without depression. Additionally, factors asso...

Patients with obsessive-compulsive disorder (OCD) have increased rates of neurological soft signs (NSS) when compared to healthy controls. However, previous findings have been confounded by the presence of co-morbidity with disorders themselves associated with increased NSS, such as schizophrenia. Moreover, it remains unclear whether NSS in OCD reflect a vulnerability to this disorder. This stu...

OBJECTIVE The error-related negativity (ERN) is a negative deflection in the event-related potential after an incorrect response, which is often increased in patients with obsessive-compulsive disorder (OCD). However, the relation of the ERN to comorbid tic disorders has not been examined in patients with OCD. This study compared ERN amplitudes in patients with tic-related OCD, patients with no...

OBJECTIVE To investigate the incidence, transition probabilities, and risk factors for obsessive-compulsive disorder (OCD) and subclinical OCD in adolescents. METHOD A two-stage epidemiological study originally designed to investigate depression was conducted between 1987 and 1989 in the southeastern United States. For the screening, a self-report depressive symptom questionnaire was administ...

Cognitive Behavioural Therapy (CBT) for preadolescent children with obsessive compulsive disorder (OCD) is typically derived from adult cognitive behavioural models of OCD; however, it unknown whether these apply to children.
