Validation of a classification system of obsessive-compulsive spectrum disorder symptoms in a non-clinical sample.

Controversy surrounds the classification of obsessive-compulsive spectrum disorder (OCSD) symptoms. In this study, we tested whether a broad OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, pathological skin picking, impulsivity, and anxiety symptoms displayed sufficient data fit. Alternatively, we tested whether a reduced OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms demonstrated superior fit. The reduced OCSD symptoms model demonstrated good data fit. However, the broader OCSD symptoms model only displayed marginal data fit. In context with other findings, results of this study support an OCSD symptoms dimension that includes obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms. Implications of these findings are discussed as they relate to proposed changes in the forthcoming edition of the Diagnostic and Statistical Manual.

When exposures go wrong: troubleshooting guidelines for managing difficult scenarios that arise in exposure-based treatment for obsessive-compulsive disorder.

Cognitive-behavioral therapy (CBT) with exposure and ritual prevention (ERP) is widely accepted as the most effective psychological treatment for obsessive compulsive disorder (OCD). However, the extant literature and treatment manuals cannot fully address all the variations in client presentation, the diversity of ERP tasks, and how to negotiate the inevitable therapeutic challenges that may occur. Within this article, we attempt to address common difficulties encountered by therapists employing exposure-based therapy in areas related to: 1) when clients fail to habituate to their anxiety, 2) when clients misjudge how much anxiety an exposure will actually cause, 3) when incidental exposures happen in session, 4) when mental or covert rituals interfere with treatment, and 5) when clients demonstrate exceptionally high sensitivities to anxiety. The goal of this paper is to bridge the gap between treatment theory and practical implementation issues encountered by therapists providing CBT for OCD.

Hairstylists' experience with chronic hair pulling.

This study examined 88 hairstylists' awareness, exposure, and perceptions about treatment for people with trichotillomania (TTM). We investigated the influence of hairstylists' obtained educational level, years of experience, and understanding of TTM in relation to their willingness to refer clients for mental health treatment. Results indicate that hairstylists notice hair loss and discussed this with their clients. Hairstylists generally reported a favorable opinion of psychotherapy and a willingness to refer clients to mental health professionals. No measured variables (e.g. experience, education, or awareness of TTM) predicted willingness to refer clients for treatment. Overall, the results from this study suggest that hairstylists may aid in the early identification of TTM symptoms, particularly for females because a greater proportion of clients seen by hairstylists are females and females more commonly present with symptoms of TTM.

Getting the hypertension Dx right: Patient positioning matters.

Taking blood pressure with the patient seated on the edge of an exam table led to misclassification of prehypertension or hypertension in 13.2% of patients.

A pilot trial of cognitive-behavioral therapy augmentation of antibiotic treatment in youth with pediatric acute-onset neuropsychiatric syndrome-related obsessive-compulsive disorder.

BACKGROUND: This study reports an open trial of family-based cognitive-behavioral therapy (CBT) in children and adolescents with obsessive-compulsive disorder (OCD) exhibiting an onset pattern consistent with pediatric acute-onset neuropsychiatric syndrome (PANS). METHODS: Eleven primarily Caucasian youth with PANS-related OCD (range=4-14 years; 6 boys) who were incomplete responders to antibiotic treatment, received family-based CBT delivered either face-to-face or via web camera. RESULTS: All participants completing treatment (8 of 8) were considered improved at posttreatment, and average obsessive-compulsive symptom severity was reduced by 49%. Significant reductions in obsessive-compulsive symptom severity and in clinician- and parent-rated OCD-related impairment were noted. Reductions in parent- and child-rated anxiety, child-rated OCD-related impairment, and comorbid neuropsychiatric symptoms were not statistically significant. CONCLUSIONS: Gains were maintained at follow-up, with 100% (6 of 6) of those assessed remaining improved. Implications for treatment and further research are discussed.

Advances in the treatment of pediatric obsessive-compulsive d-cycloserine with exposure and response prevention.

Exposure-based cognitive-behavioral therapy and serotonin reuptake inhibitor medications are efficacious treatment options for the management of pediatric obsessive-compulsive disorder. Despite established efficacy, many youths receiving either therapy remain symptomatic after acute treatment. Regardless of the rationale for persistent symptoms, a clear need emerges for treatment options that restore functioning efficiently to symptomatic youths. One innovative approach builds upon the identified role of NMDA receptors in the fear extinction process. Instead of breaking existing connections during fear extinction, new associations develop that eventually predominate over prior associations. Recent investigations have explored augmenting exposure-based cognitive-behavioral therapy with the NMDA partial agonist d-cycloserine, with preliminary results demonstrating expedited treatment gains and moderately larger effects above exposure and response prevention therapy alone. A large randomized clinical trial is underway to evaluate the efficacy and efficiency of this therapeutic combination in pediatric obsessive-compulsive disorder. Results from this trial may translate into improved management practices.

Associations between miscellaneous symptoms and symptom dimensions in adults with obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric condition with a heterogeneous array of obsessions and compulsions. Although factor analytic studies have identified symptom dimensions comprising the clinical presentation of OCD, many frequently reported miscellaneous symptoms are not considered in factor analytic studies because they do not fit conceptually within a particular symptom category, despite being functionally related. In the present study, we examined the associations between miscellaneous symptoms and OCD symptom dimensions in a sample of 111 adults with OCD. Overall, most miscellaneous symptoms were associated with one or more symptom dimensions in previously identified four- (14 of the 22 symptoms) and five-factor models (12 of the 22 symptoms). In both models, Contamination/Cleaning was the only dimension not related to any miscellaneous symptom. The present results provide information about which miscellaneous symptoms may be related to particular symptom dimensions, which will assist in clinical evaluations and help planning behavioral psychotherapy (e.g., hierarchy development).
