Studies in REST. I. Reduced Environmental Stimulation Therapy (REST) and reduced alcohol consumption

Reduced Environmental Stimulation Therapy (REST), formerly known as "sensory deprivation," was used in conjunction with pre-recorded anti-alcohol messages to reduce alcohol consumption. Subjects were college students of both sexes who were "heavy social drinkers," that is, early prodromal alcoholics. There were two studies. In the pilot study experimental subjects had two and a half hours of REST, during which they heard one of two differently worded anti-alcohol messages. After two weeks their alcohol intake dropped significantly from baseline levels (33% and 29%); control subjects showed no significant changes. In a replication and follow-up study experimental subjects had two and a half hours of REST, during which they heard a revised version of the most effective anti-alcohol message used in the pilot study. Two weeks later their alcohol consumption dropped 55% from baseline levels. These reductions in alcohol intake were fully sustained on follow-up three months and six months later. Untreated control subjects showed increased alcohol intake on follow-up.
