Root Center and Phosphatidylethanol (PEth) Study

August 25, 2023

The Root Center is working with Dr. Sheila Alessi, from UConn Health, for the PEth study. Peth is an abbreviation for Phosphatidylethanol, which is a direct biomarker of alcohol that can detect moderate to heavy drinking with high sensitivity and specificity over three week periods.



This study evaluates the efficacy of contingency management, an evidence-based treatment that provides motivational incentives to those living with Substance Use Disorder (SUD), to help support their path to recovery.


The research team specifically focuses on the improvement of the application of this treatment, with the overall goal of a reduction in drinking alcohol for those who utilize contingency management in their care.


This will help to better the understand the impact that contingency management has on a patient’s care versus the usage of standard care.
