PALABRAS CLAVE Impulsividad; UPPS; Análisis factorial confi rmatorio; Psicometría; Versión española Abstract Aim. Impulsivity is a multifaceted construct that has a prominent role in psychiatry and especially in addiction. The objective of the current study is to develop and validate a Spanish version of the short UPPS‐P impulsive behavior scale1, which assesses fi ve distinct impulsivity traits (positive urgency, negative urgency, lack of premeditation, lack of perseverance, and sensation seeking). Material and methods. One hundred and eighty‐nine participants were included in the study. Confi rmatory factor analyses supported the fi ve­factor model of the original scale. Results. The results indicated good internal reliability. External validity was supported by specifi c relationships with a scale assessing emotion regulation strategies. Conclusion. Accordingly, the short Spanish version of the UPPS‐P scale presents good psycho‐ metric properties and may be considered a promising instrument for both research and clinical practice. © 2012 Elsevier España, S.L. y SET.
