Opioid Approach Bias Modification (OABM)
June 9, 2023 updated by: University of California, San Francisco
The Neural Basis of Approach Bias Modification in Opioid Users With Chronic Pain
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.

Detailed 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: opioid approach bias training
Immediately following screening, patients will be randomly assigned to receive 6 sessions of opioid approach bias modification taking place over two weeks.
|
The investigators will use a training version of the Approach-Avoidance Task (AAT), in which patients are asked to respond to the format of presented pictures, irrespective of the pictures' content.
Pushing a presented picture away will decrease picture size, whereas pulling a picture closer will increase size.
There are 2 categories of pictures; 20 different opioid and 20 different non-medication alternative pain managing activities.
Training effect is achieved by presenting opioid pictures in push format only and non-opioid pictures in pull format only.
Two hundred training trials are presented per session.
|
Sham Comparator: sham training
Immediately following screening, patients will be randomly assigned to receive 6 sessions of sham training taking place over two weeks.
|
Sham training is identical to opioid approach bias training, except pictures are presented randomly in both formats.

Measure Description |
Time Frame |
---|---|---|
Change in reaction time on an opioid approach-avoidance task across time, baseline to end of treatment, week 3
Time Frame: baseline to end of treatment, week 3
|
millisecond reaction time of (opioid push - opioid pull) - (non-opioid push - opioid pull) on an opioid approach-avoidance task where participants are asked to respond to the format of presented pictures, irregardless of the content.
There are two categories of pictures; 20 different opioid pictures and 20 different non-opioid pictures, with two-hundred trials.
Millisecond reaction time will be measured at baseline, prior to each training session during the 2-week training period, and at week 3 post training assessment.
Primary outcome is change in reaction time across time in active vs. sham condition.
