A contextualized reinforcer pathology approach to addiction

Area of Science:

• Behavioral economics
• Addiction science
• Psychology

Background:

• Behavioral economic models explain addiction via overvaluation of immediate rewards (delay discounting) and high drug demand.
• These models focus on within-individual motivational processes.
• Learning theory highlights environmental factors, specifically the availability of alternative reinforcers.

Purpose of the Study:

• To integrate alternative reinforcers into behavioral economic models of addiction.
• To propose the contextualized reinforcer pathology model.
• To review empirical support for this integrated model.

Main Methods:

• Review of empirical literature across the translational spectrum.
• Integration of concepts from behavioral economics and learning theory.
• Conceptual analysis of addiction as a contextualized reinforcer pathology.

Main Results:

• The contextualized reinforcer pathology model provides a framework for understanding harmful drug use.
• Lack of alternative reinforcement is identified as a significant risk factor for addiction.
• The model helps explain increases in drug-related mortality and health disparities.

Conclusions:

• Integrating environmental factors, specifically alternative reinforcers, enhances behavioral economic accounts of addiction.
• The contextualized reinforcer pathology model offers a more comprehensive understanding of addiction.
• Addressing lack of alternative reinforcement may be key to ameliorating addiction and its disparities.
