ABSTRACT This study replicated and extended previous research regarding utility of an inference-based approach (IBA) to the study of Obsessive-Compulsive Disorder (OCD). The IBA is a model for the development of OCD symptoms through false reasoning. One of its key features is inferential confusion-a form of processing information in which an individual accepts a remote possibility based only on subjective evidence. In a nonclinical sample, this study examined the specificity of relations between the expanded Inferential Confusion Questionnaire (ICQ-EV) and OC symptoms. Results were that the ICQ-EV significantly predicted OC symptoms after controlling for general distress, anxiety, and depression. This finding supports the unique association between inferential confusion and OCD. Further, the ICQ-EV was a stronger predictor of certain OC symptoms than scales from the Obsessive Beliefs Questionnaire, which itself has shown strong relations with OC symptoms. Thus, both inference-based and cognitive appraisal models appear useful for understanding OCD.

    ABSTRACT: This study investigates imaginative, dissociative, and schizotypal processes that are potentially relevant to obsessive-compulsive (OC) symptoms. Students (n = 377) completed questionnaires that assessed inferential confusion, absorption, schizotypal personality, and other domains. Hierarchical regression revealed that inferential confusion and absorption were the most consistent predictors of OC symptoms; other content predicted variance for specific OC symptoms. For example, schizotypal personality predicted checking and hoarding symptoms, but not cleanliness or ordering rituals. Immersive tendencies predicted cleanliness and hoarding but not checking or ordering rituals. Results are consistent with an inference-based model of OC, in which an overreliance on imagination during reasoning gives rise to experiences that are inconsistent with reality. This study suggests additional domains that may help explain why intrusive thoughts become obsessions.

    ABSTRACT: Previous research has found that a high impact of possibility based information during reasoning prevents the resolution of doubt among those with Obsessive-Compulsive Disorder (OCD). It was expected that the ability of those with OCD to resolve obsessional doubt would improve following Inference Based Treatment (IBT). The ability to resolve doubt, including the relative impact of reality and possibility based information, was measured before and after treatment with the Inference Processes Task in a group of 35 participants diagnosed with OCD. Results confirmed that IBT improved the participants' ability to resolve obsessional doubt. Those who improved their ability to resolve doubt showed a significantly better treatment outcome. Improvements appeared mostly due to a lowered impact of possibility based information following treatment. The study did not include a control condition although results clearly indicate that the ability to resolve obsessional is closely linked to the most relevant quantifiers of treatment outcome. In addition, relatively small sample sizes prevented more powerful multiple comparisons between groups. Results suggest treatment implications and the relevance of dissolving the tenacity of obsessional doubt in OCD.

    ABSTRACT: Obsessive-compulsive disorder (OCD) is associated with visuospatial working memory deficits. Intolerance of uncertainty is thought to be a core component of OCD symptoms. Recent findings argue for a possible relationship between abilities in visuospatial memory and uncertainty. However, this relationship remains unclear in both OCD patients and healthy subjects. To address this issue, we measured performance in visuospatial working memory and the propensity to express uncertainty during decision making. We assessed their relationship and the temporal direction of this relationship in both OCD patients and healthy subjects. Baseline abilities in visuospatial working memory were measured with the Corsi block-tapping test. A delayed matching-to-sample task was used to identify explicit situations of certainty, uncertainty and ignorance and to assess continuous performance in visuospatial working memory. Behavioural variables were recorded over 360 consecutive trials in both groups. Baseline scores of visuospatial working memory did not predict the number of uncertain situations in OCD patients whereas they did in healthy subjects. Uncertain trials led to reduced abilities in visuospatial working memory to 65% of usual performance in OCD patients whereas they remained stable in healthy subjects. The present findings show an opposite temporal direction in the relationship between abilities in working memory and uncertainty in OCD patients and healthy subjects. Poor working memory performance contributes to the propensity to feel uncertainty in healthy subjects whereas uncertainty contributes to decreased continuous performance in working memory in OCD patients.
