Adaptation and validation of the Brazilian DASE and TUD scales for cocaine/crack users

Abstract

Self-efficacy for abstinence and temptation to use illicit drugs are demonstrably key elements of changing addictive behaviors. This study’s aim was to analyze the psychometric evidence for the Brazilian adaptation of the scales Drug Abstinence Self-efficacy Scale (DASE) and Temptation to Use Drugs Scale (TUD). The sample was composed of 300 men treated for cocaine and crack addiction. Análise Factorial Exploratory and internal consistency demonstrated the existence of four factors in the DASE that explained 54% of the total variation in the 24 items, and four factors in the TUD that explained 56% of the total change in the variation. The Cronbach’s alpha coefficient was at DSE .920 and TUD .927. The Brazilian adaptation of the scales showed appropriate evidence of validity in the sample of hospitalized individuals addicted to cocaine and crack.
