Data collection includes collection of BrAC measurements, as well as sur...


Manipulation of Breath Alcohol Tests: Can Specific Techniques Alter Blood Alcohol Concentration Readings?

This is a prospective cohort study. The investigators will enroll 50 healthy volunteers. In a safe environment and after signing informed consent, each participant will consume a standardized alcoholic beverage. Using a Breathalyzer, the subjects BAT will be measured. If the subject's BAT is less than 0.10 +/- 0.005, the subject will drink another alcoholic beverage. This process will continue until the subject's BAT is 0.10 +/- 0.005. The number of alcoholic beverages the subj...

Prevention of Fetal Alcohol Spectrum Disorder (FASD) by the Use of Technology

The Institute of Health Economics is conducting a study to determine how a breathalyzer linked to a cloud based alcohol monitoring system changes alcohol consumption during pregnancy in women with alcohol dependency issues. IHE posits that the ability to self-monitor blood alcohol concentration and the ability to share sobriety via email or text with loved ones and counselors may reduce alcohol consumption and thus reduce the possibility of delivering a child with FASD. ...

Remote Alcohol Monitoring to Facilitate Abstinence From Alcohol: Exp 2

Directly reinforcing abstinence from alcohol with monetary incentives is an effective treatment for alcohol dependence, but barriers in obtaining frequent, verified biochemical measures of abstinence limit the dissemination of this treatment approach. As our feasibility study demonstrates, remote breathalyzer monitoring drastically improves the practicality of delivering an alcohol contingency management intervention. In Experiment 2, we will test whether the addition of remote...

Interventions for Unemployed Hazardous Drinkers

Despite recent improvements in the US economy, unemployment remains a significant concern, and estimates indicate that one-third of unemployed persons drink at hazardous levels, adversely impacting their health and abilities to find jobs. Reinforcement interventions are highly efficacious in reducing substance use, and they can be applied to increase job-seeking activities as well. In partnership with CT United Labor Agency, this project is designed to reduce hazardous drinking...

Validation of a Specific Measure for Assessment of Compliance With Treatment in Patients With Hemophilia

InBody Validation Study

With, one in three Americans now having a body mass index (BMI) greater than 30, and the fastest growing segment of the population having a BMI greater than 40, it is paramount to conduct validation of approaches to measure body composition. Currently the dual-energy x-ray absorptiometry (iDXA) is the gold standard for measuring the body composition. But it is often difficult to perform since it is limited to specific height, weight and BMI's. InBody is a tool which uses bio el...
