Recent Study Uncovers the Association Between Nociplastic Pain and Pain-Motivated Drinking in Alcohol Use Disorder
Individuals with alcohol use disorder (AUD) often report experiencing pain, which influences them to drink as a form of self-medication. A groundbreaking study published in The Journal of Pain on January 12, 2024, by researchers from The Ohio State University and the University of Michigan, highlights the presence of nociplastic pain as a significant factor in pain-motivated drinking among this population. This novel research, identified by the DOI: 10.1016/j.jpain.2024.01.332, offers a profound understanding of the complex relationship between chronic pain and AUD.
Nociplastic pain, a type of pain caused by alterations in the way the nervous system processes pain signals, is commonly associated with conditions like fibromyalgia. It is characterized by a heightened sensitivity to pain due to neurochemical and neuroplastic changes in the central nervous system. The research leverages the American College of Rheumatology Fibromyalgia Survey, traditionally used in fibromyalgia, as a surrogate measure for nociplastic pain among individuals with AUD.
The cross-sectional observational study involved 138 participants, consecutively recruited from an academic addiction treatment facility’s patient pool, who were diagnosed with AUD. The researchers developed a new empirical tool, namely the Pain-Motivated Drinking Scale (PMDS), to quantitatively measure the frequency at which individuals with AUD consume alcohol to alleviate physical pain.
Key Findings and Implications
An overwhelming 72% of participants revealed that they consumed alcohol to gain relief from physical pain at least occasionally. More strikingly, over 42% indicated that seeking pain relief was a primary motivator for their drinking behaviors more than half of the time. Clearly, the bond between experiencing pain and the compulsion to drink is undeniable.
The PMDS showcased robust psychometric properties—it exhibited a single-factor structure and demonstrated strong internal consistency reliability and construct validity. These attributes make it a reliable instrument in assessing pain-driven alcohol consumption, adding an invaluable asset to both research and clinical practice.
The hierarchical linear regression analysis, carried out while adjusting for potential confounders and pain severity, presented a robust association between nociplastic pain and scores on the PMDS. This relationship remained significant, indicating that nociplastic pain has a unique contribution to the motivation behind drinking due to pain in individuals living with AUD.
Perspective and Clinical Significance
This research not only paves the way for targeted interventions aimed at mitigating pain-motivated drinking but also underpins the need for pain management strategies tailored to the unique challenges faced by individuals with AUD. The implementation of the PMDS in clinical settings could potentially guide healthcare professionals in recognizing pain-motivated alcohol use and designing comprehensive treatment regimes that address both pain and addiction.
In conditions where nociplastic pain is established, adequate pain management must be considered as part of the treatment protocol. Clinicians should be vigilant in assessing the risk factors contributing to AUD, integrating pain assessment tools such as the PMDS into their routine evaluations of patients presenting with symptoms of chronic pain and alcohol dependency.
Furthermore, by highlighting nociplastic pain as a significant factor, treatments that focus on desensitization of the central nervous system could become an integral component in managing AUD. Behavioral therapies, medications, and non-pharmacological interventions that address central sensitization might provide relief from both pain and the compulsion to drink, leading to better health outcomes and quality of life for this population.
Conclusions and Future Directions
The study undertaken by Hall Orman Trent and colleagues is a monumental stride in understanding the intricacies of alcohol use and pain. It elucidates the often-overlooked [phenomenon of pain-motivated drinking and introduces a validated instrument for its assessment](https://). These breakthroughs set the stage for continued exploration into the nature of pain in AUD, fostering a future where the vicious cycle of pain and alcohol dependence is effectively disrupted.
The findings also invite further investigation into the biological underpinnings and potential treatments for nociplastic pain within the context of AUD. Future studies could revolve around the efficacy of multimodal treatment strategies that simultaneously address nociplastic pain and AUD, potentially transforming the approaches adopted for individuals grappling with these co-existing conditions.

By employing the PMDS and delving into the relationship between nociplastic pain and AUD, this research not only fills a critical gap in the literature but also creates a foundation for interventions that holistically address the intertwined nexus of pain and alcohol use. As we continue to disseminate these findings across the field of addiction medicine, there is hope that improved understanding and management of pain among individuals with AUD can become a reality, significantly enhancing their recovery trajectory and broadening the scope of effective treatments available.
