A reclassification of obsessive-compulsive disorder (OCD) into a new diagnostic category spectrum of "obsessive-compulsive spectrum disorders" (OCSDs) has recently been proposed, with considerable debate, for the forthcoming Diagnostic and Statistical Manual-Fifth Edition (DSM-V). This paper provides a critical analysis of the available empirical data regarding this conceptual and nosological s...

OBJECTIVE Changes in defense mechanisms after treatment of patients with obsessive-compulsive disorder (OCD) were measured by using an established rating scale. METHOD Before and after 7-week group behavior therapy, 17 patients with DSM-III-R OCD were assessed with the Defense Style Questionnaire, Yale-Brown Obsessive Compulsive Scale, and Beck Depression Inventory. RESULTS After behavior t...

The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) is one of the most popular measures of symptom severity for childhood obsessive-compulsive disorder (OCD). This study describes the factor structure of the CY-BOCS. A total of 233 children diagnosed with OCD were evaluated with the CY-BOCS. The results indicated that 2 alternate 2-factor solutions (obsessions and compulsions; severi...

There is increasing evidence that selective basal ganglia dysfunction underlies obsessive-compulsive disorder (OCD). Recent neuroanatomical, neuropharmacological, and behavioural studies indicate a complex perceptual and cognitive role for the basal ganglia in addition to their more well-accepted motor functions. In addition, obsessive-compulsive symptoms in certain syndromes and in individual ...

Background & Aims: Metacognition is considered as an important factor in the genesis and continuation of various psychological disorders, particularly obsessive-compulsive disorder and depression. The aim of this study was comparison of Metacognitive beliefs in Major depression disorder (MDD), obsessive-compulsive disorder (OCD) and healthy groups. Methods: A total of 50 depressive patients...

OBJECTIVE The purpose of this paper is to provide evidence for the relationship between personality disorders (PDs), obsessive compulsive disorder (OCD), and other anxiety disorders different from OCD (non-OCD) symptomatology. METHOD The sample consisted of a group of 122 individuals divided into three groups (41 OCD; 40 non-OCD, and 41 controls) matched by sex, age, and educational level. Al...

Epidemiologic and neurobiologic evidence suggests that patients with comorbid obsessive-compulsive disorder (OCD) and schizophrenia may represent a special category among patients with schizophrenia. Efforts to examine the neurobiology of this group have focused on neuroimaging studies and neuropsychologic testing. Convergent evidence suggests that there may be a specific pattern of neurobiolog...

Pregnancy is a well-recognised risk factor in precipitating obsessive-compulsive disorder. We present and discuss a case with the onset of obsessive-compulsive disorder in the fourth month of gestation, which fully recovered two weeks after delivery. The phenomenology of the observed disorder was similar to earlier reports of obsessive-compulsive disorder in pregnancy, i.e. the obsessions and c...
