Problem drinkers (99 males, 41 females) wishing to quit or cut down wi
thout professional help received a 60-minute session during which they
were assessed and given at random one of these materials: Guidelines,
a two-page pamphlet outlining specific methods for achieving abstinen
ce or moderate drinking; Manual, a 30-page booklet describing the meth
ods in the Guidelines; or General Information, a package about alcohol
effects. At 12 months follow-up, subjects in the Guidelines and Manua
l conditions showed significantly greater reductions of heavy days (of
5+ drinks) than subjects in General Information (70% vs. 24%); in add
ition, significantly fewer subjects in the Guidelines and the Manual c
onditions expressed need for professional assistance with their drinki
ng (25% vs. 46% in General Information). No main effect of condition o
r gender was observed on rates of moderate drinkers. At 12 months foll
ow-up, 31% of the men and 43% of the women were rated as moderate drin
kers. It was concluded that drinkers intending to cut down on their ow
n derive greater benefit (in terms of their alcohol use) from material
s containing specific instructions to develop moderate drinking than f
rom those providing general information on alcohol effects. Clinical a
nd research implications of the findings are discussed
