Overview
To investigate the neurobiological mechanisms underlying opioid approach bias during a pilot RCT of opioid approach bias modification. The investigators are combining novel ultra-high field MRI technology with the promising treatment of modifying cognitive bias away from detrimental prescription drug use will generate novel neural data and potentially yield a new therapeutic tool to reduce problematic opioid use.
Description
The proposed study is a pilot prospective, parallel groups, randomized, double blind, sham training-controlled, 6-session (over 2 weeks) clinical trial of opioid approach bias modification (OABM) in 20 male and female veterans with chronic pain at high risk for opioid-related adverse events at the San Francisco Veterans Affairs Health Care System, between ages 18-69. The study consists of screening, 2-week cognitive training, Week-3 post-assessment. Assessment of the neurobiological mechanisms of opioid approach bias will be administered at baseline and Week-3.
Eligibility
Inclusion Criteria:
- Male and female veterans eligible for VA services
- Ages 18-69
- Chronic pain (current pain lasting ≥ 90 days)
- Prescribed chronic opioids (≥ 90 days in past year)
- High risk for opioid-related averse outcomes (≥ 20mg morphine equivalent daily dose).
Exclusion Criteria:
- Psychotic, bipolar disorders or other psychiatric disorders judged to be unstable by the PI
- Current or past history of the following: intrinsic cerebral tumors, cerebrovascular accident/disease, brain aneurysm, arteriovenous malformations, surgical implantation of neurostimulators or cardiac pacemakers, demyelinating and neurodegenerative diseases, penetrating traumatic brain injury, and any other MRI contraindications.
- No female participant will be pregnant or actively attempting to conceive to prevent any unnecessary exposure to high magnetic fields or radio frequency energy to the unborn child.
- Concurrent participation in a treatment study
- Moderately Severe/Severe withdrawal from opioids based on a score of 25 or more on the Clinical Opiate Withdrawal Scale (COWS)
