The Florida Obsessive-Compulsive Inventory (FOCI) is a new self-report questionnaire that has separate scales for symptom enumeration (The Checklist) and evaluation of symptom severity (Severity Scale). The present research investigated the FOCI in a sample of 113 patients with obsessive-compulsive disorder (OCD). The results indicated that the FOCI Severity Scale is internally consistent (alph...

OBJECTIVE Although several self-report versions of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) have been developed and used widely, few psychometric studies have established the construct validity of this measure. Therefore, we developed Korean self-report version of the Y-BOCS and evaluated its factor structure, reliability, and validity. METHODS A non-clinical student sample (n=206) ...

Recently, strategies beyond pharmacological and psychological treatments have been developed for the management of obsessive-compulsive disorder (OCD). Specifically, repetitive transcranial magnetic stimulation (rTMS) has been employed as an adjunctive treatment in cases of treatment-refractory OCD. Here, we investigate six weeks of low frequency rTMS, applied bilaterally and simultaneously ove...

The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) is a widely used instrument to assess obsessive-compulsive symptomatology. The present study provides evidence that the Y-BOCS is best represented by a three-dimensional model comprising severity of obsessions (factor 1), severity of compulsions (factor 2) and resistance to symptoms (factor 3). On the basis of exploratory factor analysis, this ...

This study reports on the development and initial psychometric properties of the Children's Saving Inventory (CSI), a parent-rated measure designed to assess child hoarding behaviors. Subjects included 123 children and adolescents diagnosed with primary Obsessive-Compulsive Disorder (OCD) and their parents. Trained clinicians administered the Children's Yale-Brown Obsessive-Compulsive Scale (CY...

OBJECTIVE Serotonin reuptake inhibitors are frequently used in first-line treatments for patients with obsessive-compulsive disorder. Nevertheless, many of these patients do not respond well to initial therapy. The hypothesis of glutamatergic dysfunction in specific brain regions has been proposed in the pathophysiology of obsessive-compulsive disorder. This study was designed to evaluate the p...

OBJECTIVE The purpose of this study was to investigate whether the presence of tic disorder is negatively associated with sertraline (SRT) outcomes, but not with continued cognitive-behavioral therapy (CBT), in a sample of youth who were unresponsive to an initial full course of CBT. METHODS In the Nordic Long-Term OCD Study, children and adolescents with OCD who were rated as nonresponders t...

OBJECTIVE Our objectives were 1) to determine hemispheric asymmetry and regional differences on the EEGs of patients with obsessive-compulsive disorder (OCD); and 2) to investigate the effects of sex, treatment response, illness duration, and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) scores on quantitative electroencephalographic (QEEG) measurements. METHOD We recorded EEGs (12-channel) ...

Background: Obsessive-compulsive disorder (OCD) is associated with heterogeneous and diverse symptoms. A diagnosis challenging when patients experience psychotic This study aimed to evaluate the pattern of symptoms in OCD. Methods: Using semi-structured clinical interviews, 185 meeting DSM-IV diagnostic criteria for OCD were selected. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) Assessmen...
