Abstract
BACKGROUND AND OBJECTIVES
Previous research has highlighted the role of dysfunctional reasoning processes (i.e. "inferential confusion") in the development and maintenance of Obsessive-Compulsive Disorder (OCD). Inferential confusion has previously been found to be a unique predictor of OC symptoms and has shown specificity for OCD. However, these findings have primarily relied on a single self-report questionnaire, and only a limited number of experimentations have been conducted to establish the specificity of inferential confusion to OCD with alternate measures. The current paper demonstrates the relationship of inferential confusion with OCD symptoms in clinical samples by using a task-based measure of inferential confusion.
METHODS
Sixty-four OCD participants, as well as thirty anxious and thirty-four healthy controls completed the recently developed Dysfunctional Reasoning Processes Task (DRPT) and related measures. Thirty-five OCD participants then completed sixteen sessions of cognitive-behavioural therapy (CBT) and completed the same measures post-treatment.
RESULTS
As predicted, dysfunctional reasoning was significantly more elevated for those with OCD relative to control groups. Reduced levels of dysfunctional reasoning during CBT were significantly associated with successful treatment outcome.
LIMITATIONS
Clinical implications should be interpreted with caution due to the relatively small sample size.
CONCLUSIONS
Our findings support the notion that inferential confusion is an important cognitive factor particularly relevant to OCD that needs to be directly addressed as a mechanism of change in CBT.
