Cognitive Bias Modification for Individuals With Opioid Use Disorder and Chronic Pain Did Not Predict Changes in...

Area of Science:

• Neuroscience
• Psychology
• Clinical Research

Background:

• Attentional bias (AB) is hypothesized to link substance use disorders and chronic pain.
• Cognitive Bias Modification (CBM) shows potential for altering ABs.
• Limited evidence exists on whether CBM-induced AB changes predict clinical symptom improvements.

Purpose of the Study:

• To investigate if CBM targeting opioid and pain cues alters AB in veterans with opioid use disorder and moderate pain.
• To determine if changes in AB correlate with improvements in pain severity, interference, catastrophizing, opioid craving, and withdrawal.

Main Methods:

• Secondary analysis of a 4-week clinical trial involving 28 veterans receiving medication for opioid use disorder (mOUD) and experiencing moderate pain.
• Comparison of CBM intervention effects against a control group.
• Assessment of pain severity, interference, catastrophizing, opioid craving, and withdrawal symptoms.

Main Results:

• CBM did not significantly alter opioid craving or pain intensity (p ≥ .111).
• No significant associations were found between CBM and other outcomes, including pain interference, pain catastrophizing, and subjective opioid withdrawal (p ≥ .125).

Conclusions:

• This pilot study found no evidence that CBM for opioid and pain cues changes pain severity or opioid craving.
• Preliminary findings suggest a potential distinction between modifying attentional biases and achieving clinically significant outcomes.
• Larger, diverse samples and advanced methodologies are needed to further explore CBM's efficacy in addiction and pain management.
