Validation of the Spanish version of the brief UPPS-P impulsivity scale for children and adolescents (BUPPS-P NA)

Abstract

The Scale of Impulsivity for Children and Adolescents (UPPS-P NA) is a self-report instrument that assesses the impulsivity trait in children and adolescents. However, the UPPS-P NA does not have a short version in Spanish. The present study aimed to develop and validate a short Spanish version of the UPPS-P NA (BUPPS-P NA). First, the UPPS-P NA questionnaire was adapted to Spanish and validated in a sample of 257 children and adolescents (M age = 12.87, SD = 5.64; 61.9% female). Then, the BUPPS-P NA was developed and validated in a sample of 1777 children and adolescents (M age = 12.59, SD = 1.37; 54.2% women). The invariance of the BUPPS-P NA as to biological sex was evaluated also. The UPPS-P NA and BUPPS-P NA scales showed an adequate fit to the data. Also, the BUPPS-P NA Scale was invariant across sex. In summary, the BUPPS-P NA Scale presents adequate psychometric properties to measure the impulsivity trait in children and adolescents.
