Observational StudyAcceptability/Feasibility of IU Intervention

Participants will complete baseline questionnaires, followed by seven days of baseline EMA. After seven days of baseline EMA, they will have a meeting with a clinician and be given the CLUE intervention targeting intolerance of uncertainty. Following this intervention, participants will be given 14 days of EMA, which will include EMI prompts that they come up with at the end of the CLUE intervention (framed as "key takeaways"). After the two week period of EMA/EMI, participants will complete a post-intervention questionnaires. In addition to similar questionnaires to those administered at baseline, acceptability and feasibility of the intervention will be assessed at post-intervention. One month after post-intervention, participants will complete a one-month follow up questionnaire battery, that will again ask about acceptability and feasibility of the intervention, as well as parallel questions from baseline and post-intervention.

Participants will complete baseline questionnaires, followed by seven days of baseline EMA. After seven days of baseline EMA, participants will be assigned 14 days of EMA. After the two week period of EMA, participants will complete a post-intervention questionnaires. In addition to similar questionnaires to those administered at baseline. One month after the post-intervention questionnaires, participants will complete a one-month follow up questionnaire battery, that will include parallel questions from baseline and post-intervention. As these participants did not receive the intervention following their baseline EMA, they will be given the opportunity to schedule an appointment for the intervention after they have completed their one-month follow up questionnaire.

Following the intervention, participants will receive personalized prompts whenever they report elevated stress or anxiety. These prompts will be generated at the end of the intervention session, and will only be sent to individuals in the EMI condition.

CLUE consists of an hour long intervention, followed by a 2-week long EMI. During the hour long intervention session, participants will receive psychoeducation (i.e., defining uncertainty), discuss myths associated with uncertainty (e.g., if I do not plan things, they will go poorly), and discuss behavioral experiments that can be done to challenge uncertainty beliefs.
