Lifetime Alcohol Exposure Measures Show Promise in Assessing Mental Health Risks

A recent study published in the Addiction journal examines the reliability and validity of self-reported measures of lifetime alcohol consumption. The research, led by investigators at the Princess Alexandra Hospital in Brisbane, Australia, aimed to assess the effectiveness of existing instruments in measuring lifetime alcohol exposure. The study's findings suggest that current measures are generally valid and reliable, but highlight the need for refinement to capture binge or episodic drinking.

Key Takeaways:

• The study reviewed 1607 unique records and identified 24 studies that met the inclusion criteria, with 9 meeting the criteria for full-text review.
• The most frequently used instrument was the Lifetime Drinking History (LDH) (67%), and most studies were conducted in North America (78%).
• The study found that test-retest reliability ranged from 0.67 to 0.92, and concurrent and construct validity with external reference measures ranged from 0.40 to 0.80, indicating generally acceptable performance.
• Existing instruments for measuring lifetime alcohol exposure appear to be valid and reliable, but lack standardization and may fail to capture binge or episodic drinking.

Statistics:

• 6010 participants (3478 male, 2532 female) with sample sizes ranging from 49 to 3255 were included in the 24 studies.
• The retest intervals in the 8 studies assessing test-retest reliability ranged from 14 days to 13 years.
• The study found that 78% of studies collected alcohol exposure data via face-to-face interview.
• The study highlighted important gaps in existing instruments for measuring lifetime alcohol exposure.
