The This study aimed to build and provide evidence of validity and accuracy of a psychological measure called Escala de Estressores do Trânsito (ESET). The study included 472 subjects who responded to the scale originally comprised 72 items. The result after factor analysis enabled us to construct validity remaining 37 items, explaining 62.17% of the variance, with factor loadings above 0.40 and reliability of 0.96. The ESET presented four factors: vehicle (19 items with α = 0.96); Driver (seven items and with α = 0.87); Routes (seven items and with α = 0.80) and Environment (four items and α = 0.83). It discusses about the importance of building instruments focused on the area of Traffic Psychology, considering the scarcity of instruments that measure stressors to the context of the Brazilian traffic.
