Network intervention analysis of ACT processes in cocaine use disorder

Area of Science:

• Psychology
• Clinical Psychology
• Addiction Medicine

Background:

• Cocaine Use Disorder (CUD) presents significant treatment challenges with frequent relapse.
• Current treatments for CUD have limited long-term efficacy.
• Identifying modifiable mechanisms is crucial for improving CUD recovery outcomes.

Purpose of the Study:

• To identify cognitive-affective processes that support recovery from CUD.
• To investigate mechanisms targeted by Acceptance and Commitment Therapy (ACT) in CUD treatment.

Main Methods:

• Secondary analysis of a randomized controlled trial (RCT) involving 110 participants with moderate to severe CUD.
• Comparison of ACT combined with Contingency Management versus Drug Counseling combined with Contingency Management.
• Network intervention analysis to assess dynamic interaction changes pre- and post-treatment.

Main Results:

• Experiential avoidance was identified as a primary treatment target with the highest centrality.
• Alignment with personal values directly correlated with successful cocaine abstinence.
• Network analysis revealed specific pathways influenced by ACT.

Conclusions:

• Experiential avoidance and value-based living are key mechanisms in ACT for CUD treatment.
• Findings support the development of personalized ACT-based interventions for CUD.
• This research elucidates how ACT promotes cocaine cessation.
