The present study aims to evaluate the factorial structure and measurement invariance according to sex of the Assertiveness Inventory of Gambrill and Richey (1975) in Peruvian adolescents composed of two subscales of Degree of Discomfort and Response Index, using a non-probabilistic sample of 639 Peruvian adolescents aged 14 to 20 years (ME= 15.84, SD= 0.86). Evidence of validity was obtained based on the criterion of judges as part of the contextual and linguistic adaptation process for the evaluated population. Confirmatory factor analysis was performed on 3 models of the degree of discomfort (GI) subscale and 3 models on the Response Rate (RP) subscale. Subsequently, the equivalence of measurement of both subscales was evaluated, showing that this measure is invariant according to sex in Peruvian adolescents.
