Sweat-patch testing detects inaccurate self-reports of alcohol consumption

|January 1, 1984
Summary
Many alcohol drinkers inaccurately report their intake, with over half underreporting consumption. Objective sweat-patch tests reveal discrepancies, suggesting skepticism towards self-reported alcohol data for diagnosing alcohol abuse.
Area of Science:
- Clinical Biochemistry
- Addiction Medicine
- Forensic Toxicology
Background:
- Accurate self-reporting of alcohol consumption is crucial for clinical assessment and diagnosis of alcohol use disorders.
- Previous studies indicate potential discrepancies between self-reported alcohol intake and actual consumption.
Purpose of the Study:
- To quantitatively assess the accuracy of self-reported alcohol consumption in a cohort of social drinkers.
- To compare self-reported data with objective measures of alcohol intake.
Main Methods:
- Twenty-two volunteers maintained a written log of all alcoholic beverages consumed over one week.
- Actual alcohol intake was concurrently monitored using the transdermal ethanol (sweat-patch) test.
- Self-reported data was compared against objective sweat-patch test results.
Main Results:
- Only 40.9% of subjects accurately reported their alcohol consumption.
- A significant proportion (50%) underreported their intake, with some falsely reporting complete abstinence.
- Objective sweat-patch tests identified alcohol consumption in individuals who claimed to have abstained.
Conclusions:
- Self-reported alcohol consumption data is often unreliable and should be critically evaluated.
- Objective laboratory methods, such as the sweat-patch test, are valuable for verifying alcohol intake.
- Increased reliance on objective testing is recommended for accurate diagnosis of alcohol abuse and monitoring treatment efficacy.
