Social Cognition in Opioid Use Disorder

Area of Science:

• Neuroscience
• Psychology
• Social Cognition

Background:

• Opioid use disorder (OUD) is linked to cognitive impairments.
• Social cognition, including facial emotion recognition and theory of mind (ToM), is understudied in OUD.
• Understanding these deficits is crucial for addressing functional impairments in OUD.

Purpose of the Study:

• To investigate facial emotion recognition and ToM in individuals with recovered OUD on Buprenorphine+Naloxone (B/N) maintenance treatment.
• To compare social cognitive abilities between individuals with OUD on B/N treatment and healthy controls.
• To explore the relationship between duration of opioid use and social cognitive deficits.

Main Methods:

• 32 individuals with recovered OUD on B/N treatment and 32 healthy controls participated.
• Assessed facial emotion recognition, faux pas recognition (ToM-decoding), and reading the mind from the eyes (ToM-reasoning).
• Included standard neurocognitive tasks for comprehensive assessment.

Main Results:

• Individuals on B/N treatment showed significant deficits in facial emotion recognition and both aspects of ToM compared to controls.
• Specific deficits included reduced accuracy in recognizing anger and fear, with a bias towards identifying emotions as sad.
• Longer duration of opioid use correlated with greater difficulty in recognizing anger.

Conclusions:

• Individuals on B/N maintenance treatment experience notable difficulties in recognizing others' emotions and mental states.
• Impaired social cognition may underlie interpersonal and social functioning challenges in people with OUD.
• Findings highlight the importance of addressing social cognitive deficits in OUD treatment and recovery.
