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: 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.

    ABSTRACT: Obsessions – particularly those directly relating to causing harm – often contain or imply evaluative dimensions about the self, reflecting a fear as to who the person might be – or might become. Following from research indicating that such beliefs are relevant to OCD, and the wider literature in social psychology regarding ‘feared’ or ‘undesired’ self-guides, the current study describes the development and validation of a new questionnaire—the Fear of Self Questionnaire, in 8- and 20-item versions. The questionnaire was piloted in two non-clinical samples (n=258; n=292). Exploratory and confirmatory factor analyses supported the unidimensionality of the measure. The questionnaire showed a strong internal inconsistency, and good divergent and convergent validity, including strong relationships to obsessional symptoms and with other processes implicated in cognitive models of OCD (e.g. obsessive beliefs, inferential confusion). Implications are discussed.
