Summary

The investigators are examining whether conditions of ambiguity during decision-making may prime intolerance of uncertainty beliefs (i.e., difficulties coping with ambiguity, unpredictability, and the future) and lead to impaired performance when individuals with obsessive-compulsive disorder (OCD) are making uncertain decisions compared to non-psychiatric controls.

Detailed description

The primary aims of this study are to examine the extent to which individuals with OCD avoid decisions that involve ambiguity through the use of self-report and behavioral measures. Specifically, the investigators will examine how individuals with OCD minimize risk at the expense of monetary profit under conditions of ambiguity (relative to risky but unambiguous options) compared to non-psychiatric controls utilizing a series of judgment and decision-making (JDM) tasks.

Conditions

• Obsessive-Compulsive Disorder

Interventions

Type	Name	Description
BEHAVIORAL	Decision-Making Tasks	All participants will receive a structured diagnostic assessment and complete self-report questionnaires about cognitive factors, decision-making styles, and anxiety/mood symptoms. They then will be guided through three judgment and decision-making (JDM) paradigms (the Risk and Ambiguity Task, the Beads Task, and the Balloon Analogue Risk Task), each of which each has been modified to differ by whether the likelihood of potential adverse outcomes is provided (or whether it remains ambiguous).
