Decision Making in Chronic Pain & Alcohol Use Disorder

Status Not yet recruiting

Clinical Trial Summary

The objective of this within-subject study is to test the effects of Episodic Future Thinking (EFT) and Low-intensity Focused Ultrasound (LIFU) interventions on the pain of subjects who have chronic pain and alcohol use disorder(s).

Clinical Trial Description

This study will have a within-subject design. Participants will complete a baseline session (S1) and three intervention sessions. Specifically, participants will complete one intervention session consisting of episodic future thinking (EFT) and low-intensity focused ultrasound (LIFU), a second intervention session consisting of EFT and a control condition for LIFU ("sham-LIFU"), and an intervention session consisting of a control condition for EFT, called control episodic thinking (CET) and LIFU. Measures of chronic pain, alcohol valuation, alcohol craving, and delay discounting will be collected before and after each intervention session. The EFT intervention has participants generate positive events and related cues through a researcher-administered interview-based questionnaire. Participants will be asked to think about and describe positive events that could occur at each of the 6 delays in the future (i.e., 1 week, 1 month, 3 months, 1 year, 5 years, and 25 years). During the LIFU condition, participants will have an ultrasound transducer placed on their head, where brief ultrasound pulses are delivered to the desired brain area. CET requires participants to think about and describe positive events that occurred at each of 6 delays in the past (e.g., last night, yesterday in the afternoon, yesterday in the evening, yesterday in the morning, yesterday in the night, and the night before). After generating these cues participants will be asked to read and consider their cues as they complete the measures again that were collected prior to the cue generation. The sham LIFU condition may be active with ultrasound blocking, or inactive so that it would not deliver stimulation. All participants will complete all three intervention sessions. The first day will be the consent, MRI, and CT scans required for the LIFU intervention. The remaining three intervention sessions will occur in a counterbalanced order. The first and second sessions will be separated by 2-3 weeks, and the remaining sessions will be separated by approximately 1 week. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
