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: Obwohl die kognitive Verhaltenstherapie, häufig in der Form der Exposition und Reaktionsverhinderung, das in der Behandlung der Zwangsstörung am weitesten verbreitete Behandlungsverfahren darstellt, profitieren Betroffene mit bestimmten Subtypen der Zwangserkrankung (z.B. überwertigen Ideen oder ich-syntonen Zwangsgedanken) davon nur unzureichend oder gar nicht. Aufgrund der begrenzten Erfolge von auf verhaltenstherapeutischen oder kognitiv-verhaltenstherapeutischen Modellen basierenden Verfahren hat sich die Forschung vermehrt ausschließlich kognitiven Theorien und Behandlungsmodellen zugewandt. Der inferenzbasierte Ansatz zur Behandlung der Zwangsstörung geht davon aus, dass zwangstypische Kognitionen und Bewertungen von vorausgehenden Zweifeln und Inferenzen herrühren. Dieser Ansatz konzentriert sich auf die fehlerhaften Denkprozesse, die dem zwanghaften Zweifeln zugrunde liegen, welches Zwangsverhalten auslöst. Die vorliegende Arbeit fasst den gegenwärtigen Stand des inferenzbasierten Modells und die es stützenden empirischen Befunde zusammen.

    • "Yet, inferential confusion as measured by the ICQ has been found to be distinct from overestimation of threat, and is independently related to most obsessive-compulsive symptoms when controlling for overestimation of threat (Aardema et al. 2006b). In fact, multidimensional studies controlling for negative mood states and other cognitive domains have revealed inferential confusion as the strongest predictor of obsessive-compulsive symptoms (Aardema et al. 2008; Emmelkamp and Aardema 1999; Wu et al. 2009). The construct is also distinct from Thought Action Fusion, which albeit phonetically similar, refers to the belief having a thought can increase the likelihood of an event occurring, or that a thought is the moral equivalent of carrying out the event (Rachman and Shafran 1999).

    ABSTRACT: The current study represents the further development and validation of an expanded version of the Inferential Confusion Questionnaire (ICQ-EV) in non-clinical and clinical samples. Inferential confusion seems to be particularly relevant to Obsessive-Compulsive Disorder (OCD) and is defined as a failure to recognize the unrealistic nature of obsessions due to a subjective form of reasoning. Factor analysis of the item-set of the ICQ-EV indicated a one-dimensional solution in non-clinical and clinical samples. It was hypothesized that inferential confusion as measured by the ICQ-EV would be particularly relevant to participants with OCD. Results confirmed convergent validity with strong relationships between the ICQ-EV and obsessive-compulsive symptoms in all samples independent of other cognitive domains and general distress. In addition, those with OCD scored higher on the ICQ-EV than non-clinical controls and a mixed anxiety disorder group so confirming group-criterion validity. Finally, the ICQ-EV also showed clinical validity with change in ICQ-EV scores during treatment significantly related to successful treatment outcome.
