Myth of the pure obsessional type in obsessive--compulsive disorder.

Background: Several studies have identified discrete symptom dimensions in obsessive-compulsive disorder (OCD), derived from factor analyses of the individual items or symptom categories of the Yale-Brown Obsessive-Compulsive Scale Symptom Checklist (YBOCS-SC). This study aims to extend previous work on the relationship between obsessions and compulsions by specifically including mental compulsions and reassurance-seeking. Because these compulsions have traditionally been omitted from prior factor analytic studies, their association to what have been called "pure obsessions" may have been overlooked.

The OCI-R: validation of the subscales in a clinical sample.

The psychometric properties of the Obsessive-Compulsive Inventory-Revised (OCI-R) subscales have not been validated in a clinical sample of individuals diagnosed with obsessive-compulsive disorder (OCD). Data were collected on 186 patients diagnosed with OCD and 17 patients diagnosed with generalized anxiety disorder (GAD) using the OCI-R and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Confirmatory factor analysis revealed an acceptable factor structure.

An evaluation of three brief programs for facilitating recovery after assault.

Ninety female recent assault survivors who met symptom criteria for posttraumatic stress disorder (PTSD) were randomized to one of three interventions: Brief Cognitive Behavioral Intervention, which focused on processing the traumatic event (B-CBT); assessment condition (AC); or supportive counseling (SC). Within 4 weeks of an assault, participants met weekly with a therapist for four 2-hr sessions. Across all interventions, participants reported decreases in PTSD symptoms, depression, and anxiety over time.

Differential response to placebo among patients with social phobia, panic disorder, and obsessive-compulsive disorder.

Objective: Placebo effects in treatment of three anxiety disorders were compared.

Method: Treatment response and patients' treatment expectancy were examined by using data from 70 patients with obsessive-compulsive disorder, social phobia, or panic disorder who received placebo in three randomized, controlled trials comparing cognitive behavior therapy, medication, and their combination to placebo.

Results: Patients with obsessive-compulsive disorder were less likely to respond to placebo than patients with generalized social phobia or panic disorder.

Impact of personality disorders on treatment outcome for female assault survivors with chronic posttraumatic stress disorder.

This study examined the impact of comorbid personality disorders on the outcome of cognitive behavioral treatment for women with chronic posttraumatic stress disorder (PTSD). Seventy-five adult women with PTSD resulting from rape or nonsexual assault in adulthood or sexual abuse in childhood were treated with prolonged exposure with or without cognitive restructuring. Assessment of personality disorders found that 39% of participants met DSM-IV criteria for some personality disorder diagnosis.

Health concerns in patients with obsessive-compulsive disorder.

In the present study, individuals with obsessive-compulsive disorder (OCD) who also had excessive health concerns (n = 56) were compared with OCD individuals without such concerns (n = 343) regarding their OCD symptom severity, types of obsessions and compulsions, insight into the irrationality of their obsessions, and prevalence of generalized anxiety disorder. While the presence of health concerns did not affect the severity of OCD symptoms, the groups differed with respect to the types of symptoms displayed: those with health concerns had more somatic and harm obsessions, and checking compulsions: whereas those without such concerns had more contamination obsessions and washing compulsions. The insight of both groups ranged from poor to excellent, yet the number of individuals with poor insight was greater among those with health concerns than those without.
