Reliability of a retrospective decade-based life-course alcohol consumption questionnaire administered in later life.

摘要: Background and aims Retrospective measures of alcohol intake are becoming increasingly popular; however, the reliability such remains uncertain. This study assessed a retrospective decade-based life-course consumption questionnaire, based on standardized Alcohol Use Disorder Identification Test–Consumption (AUDIT-C) administered in older age well-characterized cohort study. Design, setting, participants measurements A life-grid was to 5980 (72% male, mean 70 years) Whitehall II covering frequency drinking, number drinks typical drinking day consuming six or more single occasion teens (16–19 years) through 80s. A subsample 385 individuals completed repeat survey determine test–retest reliability. Retrospective were also compared with prospectively ascertained information used predict objectively measured systolic blood pressure test their predictive validity. Findings Across all decades life, generally good (κ range = 0.62–0.78 for frequency, 0.55–0.62 usual 0.57–0.65 occasion). The concordance between prospective consistently moderate high. method performed better than question identifying life-time abstainers. related manner anticipated. Conclusion A AUDIT-C grid provides relatively reliable measure across life-course.
