Test of Target Engagement of Ambiguity Aversion

Description

In this trial, participants will be randomized to one of two single session interventions (SSI). They will complete a decision making task before and after the SSI to measure their behavioral and brain responses to ambiguity, all on the same day. They will also complete a brief measure of hopelessness before and after the SSI. The main analysis will compare changes in ambiguity aversion before and after the interventions. Participants will also be asked to complete questionnaires before completing the task and SSI. The questionnaires will be about the participant’s emotions and symptoms of depression and anxiety, personality, and avoidance/tolerance of uncertainty.
