Understanding how uncertainty affects anxiety and related disorders

Computational Modeling of Ambiguity Aversion in Internalizing Disorders: Neural and Behavioral Markers, and a Test of Target Engagement

NIH-funded research Northwestern University at Chicago · NIH-11054132

This study is looking at how people with anxiety feel and react when faced with uncertain situations, and it will involve 140 adults who experience anxiety and depression; the researchers want to see if a short activity can help them feel more comfortable with uncertainty.

What this research studies

This research investigates how individuals with anxiety-related disorders respond to uncertain situations, focusing on a concept known as ambiguity aversion. By using advanced computational modeling and brain activity measurements, the study aims to identify behavioral and neural markers associated with this aversion. The research will involve 140 adult participants who struggle with uncertainty, examining how their responses to ambiguous choices relate to their anxiety and depression levels. Additionally, a brief behavioral intervention will be tested to see if it can effectively reduce ambiguity aversion.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults aged 21 and older who experience moderate to high levels of anxiety and intolerance to uncertainty.

Not a fit: Patients who do not experience anxiety-related disorders or who have low intolerance to uncertainty may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatments for anxiety-related disorders by targeting the mechanisms of uncertainty tolerance.

How similar studies have performed: Previous research has shown promising results in understanding the role of uncertainty in anxiety, making this approach both relevant and potentially impactful.
