Abstract Shared Mobility Services (SMC) is an innovative transportation alternative in urban centers. Thus, using a survey with 597 users, through a Confirmatory Factor Analysis, the determinants of SMC use in the Brazilian context was identified. Economic benefits, pleasure, and sustainability are predictors of Attitude toward SMCs and behavioral intent about SMCs. There was a negative relationship between Reputation and Attitude for the SMCs. A positive relationship was observed between Attitude and SMC and Behavioral Intent. These results contributed methodologically for validating a scale of measurement of the adherence determinants of the use of SMC in the Brazilian context.
