Abstract
Before/after survey data were used to investigate the effect that a sudden and dramatic wine and spirits availability increase in Iowa might have had on heavy and problem drinker rates. Three state surveys representing the age 18+ non-institutionalized population of Iowa were conducted in 1985, 1986 and 1989. Neither previous sales analyses nor this survey data analysis support the Distribution of Consumption Prevention Model prediction that increased wine and spirits availability would produce significant and lasting consumption increases and, in turn, heavy drinker and problem drinker prevalence rate increases.
