Examining the generality and specificity of gender moderation in obsessive compulsive beliefs: Stacked prediction by correspondence analysis.

Objectives: In this study, we examined the degree of generality and specificity of OC beliefs are moderated by gender among individuals with OC disorders.

Methods: The diagnostic groups consisted of: (1) individuals with obsessive-compulsive disorder (OCD; N = 398); (2) individuals with other anxiety disorders (N = 104); and (3) undergraduate students (N = 285). To evaluate the gender moderating effect, we employed stacked prediction by correspondence analysis (CA).

The structure of obsessive compulsive symptoms and beliefs: A correspondence and biplot analysis.

Research has suggested that obsessive-compulsive (OC) beliefs are differentially predictive of OC symptom dimensions. One additional way in which beliefs and symptoms may be related is by severity; that is, the role of beliefs may vary as a function of symptom severity. In order to evaluate this possibility, correspondence analysis with biplot was applied to evaluate the association between OC beliefs and OC symptom severity across three subsamples, individuals with obsessive-compulsive disorder (OCD; N=398), individuals with anxiety disorders (N=104), and undergraduate students (N=285).

Hoarding disorder and obsessive-compulsive disorder show different patterns of neural activity during response inhibition.

Although hoarding disorder (HD) has been historically conceptualized as a subtype or dimension of obsessive-compulsive disorder (OCD), preliminary evidence suggests that these two disorders have distinct neural underpinnings. The aim of the present study was to compare the hemodynamic responses of HD patients, OCD patients, and healthy controls (HC) during response inhibition on a high-conflict Go/NoGo task that has previously proved sensitive to OCD. Participants comprised 24 HD patients, 24 OCD patients, and 24 HCs who completed a Go/NoGo task during functional magnetic resonance imaging (fMRI).
