Portuguese version of the Quality of Life Enjoyment and Satisfaction Questionnaire: a validation study

Abstract

The Portuguese version of the Q-LES-Q possesses sound internal validity. The English version of the Q-LES-Q was adequately adapted to Portuguese. Inhalant users may present lower levels of satisfaction with social life and overall quality of life than crack users. The Portuguese version of the Q-LES-Q is a reliable questionnaire for future research and clinical use with substance users in Brazil.
