OBJECTIVE To compare obsessive-compulsive (OC) symptoms in patients with Prader-Willi syndrome (PWS) and symptoms in a group of patients presenting with "Prader-Willi-like" features but without the genetic abnormalities associated with PWS. METHOD 16 patients aged 4 through 20 years were evaluated in a clinic specializing in the assessment and management of behavioral and food-related problem...

BACKGROUND Recent statistical approaches based on factor analysis of obsessive compulsive (OC) symptoms in adult patients have identified dimensions that seem more effective in symptom-based taxonomies and appear to be more stable over time. Although a phenotypic continuum from childhood to adulthood has been hypothesized, no factor analytic studies have been performed in juvenile patients, and...

A growing body of research has linked poor distress tolerance (DT) to obsessions, but not other OC symptom domains. However, limited research has been conducted with clinical samples. Further, there is a dearth of research regarding the moderating influence of DT on the contribution of stress to OC symptoms. In Study 1, we sought to test the specificity of the link between poor DT and greater o...

OBJECTIVE The aim of this study was to determine the childhood clinical predictors of early adult outcomes in pediatric-onset obsessive-compulsive disorder (OCD) and to assess whether dimensional subtypes of OCD and the presence of comorbid tic symptoms influence long-term outcomes. METHODS We conducted a longitudinal cohort study in which 45 of 62 eligible children with OCD were reassessed a...

BACKGROUND Overcommitment (OC) is a pattern of excessive striving that has been associated with alterations in the hypothalamus-pituitary-adrenal (HPA) system. To investigate whether overcommitment is associated with alterations in HPA system function we measured cortisol and adrenocorticotropin (ACTH) release in response to the combined dexamethasone/CRH test. METHODS We recruited 92 men and...

Previous research has shown strong connections of anger experience and expression with obsessive-compulsive (OC) symptoms. Additionally, studies have demonstrated links between family environment variables and obsessive-compulsive disorder (OCD). Our study aims to integrate the perspectives from these two literatures by exploring the moderating roles of family cohesion and family adaptability i...

Emotion regulation deficits may contribute to the maintenance of anxiety and distress for individuals with generalized anxiety disorder and other emotional disorders. Recent work suggests a similar model for obsessive-compulsive disorder (OCD); however, the associations between obsessive-compulsive (OC) symptoms and emotion regulation deficits require further empirical support. The present stud...

The relationship of bronchitic symptoms to ambient particulate matter and to particulate elemental and organic carbon (OC), nitrogen dioxide (NO2), and other gaseous pollutants was examined in a cohort of children with asthma in 12 Southern California communities. Symptoms, assessed yearly by questionnaire from 1996 to 1999, were associated with the yearly variability of particulate matter with...

Individuals who are not clinically diagnosed with obsessive-compulsive disorder (OCD) but still display obsessive-compulsive (OC) tendencies may show cognitive impairments. The present study investigated whether there are subgroups within a healthy group showing characteristic cognitive and emotional performance levels similar to those found in OCD patients and whether they differ from OCD subg...

OBJECTIVES The systemic and cognitive side effects of hepatitis C virus (HCV) therapy may be incapacitating, necessitating dose reductions or abandonment of therapy. Oral cannabinoid-containing medications (OCs) ameliorate chemotherapy-induced nausea and vomiting, as well as AIDS wasting syndrome. The efficacy of OCs in managing HCV treatment-related side effects is unknown. METHODS All patie...
