PEDROSO, Rosemeri Siqueira et al. Outcome expectancy considering the use of alcohol, cannabis and tobacco. Rev. psiquiatr. Rio Gd. Sul [online]. 2006, vol.28, n.2, pp.198-206. ISSN 0101-8108.

This article aims to perform a theoretical review about the outcome expectancy construct considering the use of alcohol, cannabis and tobacco. Outcome expectancy is determined by people's belief about the effects of a drug. It is an important variable for the treatment of chemically dependent patients. Searches in the electronic databases MEDLINE, PsycINFO, ProQuest, Ovid, LILACS and Cork were carried out, using the following descriptors: belief, expectancy, expectation, drugs, psychoactive, and effect. Results showed that outcome expectancy considering the use of those substances can be generated from: exposure to conditioning stimuli, physical dependence, personal and cultural beliefs, and situational and environmental factors. In conclusion, there is the need of new researches on expectancies related to psychoactive substances and age groups in order to have a better understanding of this construct.

Keywords : Outcome expectancy; alcohol; cannabis; tobacco.
