The UPPS-P scale is widely used to assess impulsivity. For this reason, the psychometric properties of the extensive version of UPPS-P were analyzed from the Rasch polytomous model. Eight hundred Argentine adolescents aged 12 to 18 years participated in the study. As a result, it was found that the dimensions of the UPPS-P presented an adequate fit to the Rasch model, adequate levels in the Person Separation Index (PSI), some items with local dependence and an adequate level of unidimensionality. It is concluded that the scale is a valid instrument to assess impulsivity in adolescents; therefore, a conversion table with interval scores is presented to increase the measurement precision of the instrument.

Background: Antisocial behavior refers to a set of acts that violate the rules established for the coexistence of society. One of the self-report measures to assess this type of behavior is the normative deviance scale (NDS). Objective: Considering that in the Argentine context no studies on the psychometric properties of the scale were found, the present study aimed to analyze the psychometric properties of the scale in a sample of Argentine youths. Method: To this end, a sample of 794 participants aged between 18 and 25 years was collected. A confirmatory factor analysis was performed; the composite reliability was calculated; and the convergent, discriminant and concurrent validity was assessed (using a self-control scale). In addition, the invariance of the factorial structure of the scale was analyzed. Results: The results confirmed the original factorial structure of the scale with...
