Estimating under- and over-reporting of drinking in national surveys of alcohol consumption: identification of consistent biases across four English-speaking countries.

ABSTRACT:

Background and aims

Questions about drinking 'yesterday' have been used to correct under-reporting of typical alcohol consumption in surveys. We use this method to explore patterns of over- and under-reporting of drinking quantity and frequency by population subgroups in four countries.

Design

Multivariate linear regression analyses comparing estimates of typical quantity and frequency of alcohol consumption with and without adjustments using the yesterday method.

Setting and participants

Survey respondents in Australia (n = 26 648), Canada (n = 43 371), USA (n = 7969) and England (n = 8610).

Measurements

Estimates of typical drinking quantities and frequencies over the past year plus quantity of alcohol consumed the previous day.

Findings

Typical freque
