Is a Ruminative Thinking Style Related to Obsessive-Compulsive Symptom Severity Beyond Its Associations with Depressive and Anxiety Symptom Severity?

Previous studies suggest that a ruminative thinking style (RTS) is positively associated with the severity of obsessive-compulsive symptoms and might be involved in the maintenance of obsessive-compulsive disorder (OCD). We sought to replicate this association in a sample of individuals with OCD, controlling for depressive and anxiety symptom severity, and to extend previous studies by including an interview measure of obsessive-compulsive symptom severity. A sample of 140 individuals diagnosed with OCD participated in a cross-sectional observational study. Participants completed questionnaire measures of an RTS as well as obsessive-compulsive, depressive, and anxiety symptom severity. Obsessive-compulsive symptom severity was additionally assessed with an interview. When statistically controlling for depressive and anxiety symptom severity, an RTS continued to predict the questionnaire, but not the interview measure of obsessive-compulsive symptom severity. We discuss possible explanations for these mixed findings, emphasizing the unique aspects of each measure, and consider implications for further research on OCD.

Thought-Action Fusion as Predictors of Obsessive-Compulsive Symptom Dimensions

Objective There have been several studies investigating the relationships between dysfunctional beliefs and obsessive-compulsive (OC) symptoms in obsessive-compulsive disorder (OCD). However, studies about the relationships between dysfunctional beliefs, especially thought-action fusion (TAF), and OC symptom dimensions have been scarce. Therefore, this study examined to what extent and how TAF subcomponents account for unique variability in four OC symptom dimensions.Methods Sixty-five patients with OCD and 45 healthy controls aged between 18 and 30 years completed measures for OC symptom dimensions, OC symptoms, and dysfunctional beliefs such as TAF, trait-guilt, and inflated responsibility.Results Three facets of TAF were exclusively associated with two symptom domains, namely, responsibility for harm and unacceptable thoughts, and explained the additional but small amount of variance to predict these two domains. In particular, the likelihood-others TAF positively predicted the unacceptable thoughts domain, whereas the likelihood-self TAF negatively predicted the aforementioned domain. For OC symptoms measured by the OC Inventory, no TAF components predicted the corresponding obsessing and mental neutralizing symptoms.Conclusion This study provides supporting evidence that the three TAF subcomponents may be differently associated with certain OC symptom dimensions, and a dimensional approach may complement typical symptom-oriented OC measures.

An Obsessive-Compulsive Symptom-Related Headache in a Patient with Schizophrenia

Obsessive-compulsive symptoms are prevalent, manifold, and sometimes insidious in patients with schizophrenia. In this case study, we reported an intractable headache that bears a close relationship with obsessive-compulsive symptoms in a schizophrenia patient. In a series of treatments, the headache was miraculously susceptible to haloperidol treatment.
