Abstract
The Substance Use Risk Profile Scale (SURPS) was developed to screen four types of personality risk types related to substance use disorders (hopelessness, anxiety sensitivity, impulsivity, and sensation seeking). In this study, we evaluated the psychometric proprieties and reliability of the Brazilian Portuguese adaptation of the SURPS. It was also explored in this study whether the four personality types measured by the SURPS would differentially associate with motivation for specific psychoactive substance use. A cross-sectional design study was adopted in which 325 Brazilian participants took part (mean age of 27.82, SD = 5.65). Internal consistency and factor model evaluation of the scale were carried out. Results indicated the SURPS Brazilian version has good internal consistency and is a valid instrument for measuring four distinct personality dimensions within the Brazilian population (RMSEA = .05; SRMR = .07; CFI = .90). Additionally, results suggested that the hopelessness, anxiety sensitivity and sensation seeking subscales were associated with preferential substances of use.
