Craving & Decision-Making

United States160 participantsStarted 2024-06-18

Plain-language summary

Craving is the strong desire for something, such as for substances in drug addiction and food or other activities in everyday life. Recent work suggests craving can influence how people make decisions and assign value to choice options available to them, yet the neural mechanisms underlying these interactions between craving and valuation remain unknown. To address this, this study uses cognitive decision-making tasks that measure how much individuals will pay (from a study endowment) to have everyday consumer items or snack foods when they crave something specific (opioids or a specific snack, respectively). First, the study will identify the neural mechanisms for how drug craving (craving for opioids) interacts with valuation for consumer items that have associations with drug use or not in people receiving treatment for opioid use disorder (OUD). This will be evaluated in the activity patterns and interactions among brain regions involved in craving and value assignment during decision-making. Then, the study will examine for parallel mechanisms for how food craving (craving for a specific snack) interacts with valuation for snack food items that have similar features to the craved snack or not in people receiving treatment for OUD and non-psychiatric community control participants.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
