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 psychometric
properties and may be considered a promising instrument for both research and clinical
practice.
