Psychometric Properties of a Spanish Version of the UPPS-P Impulsive Behavior Scale: Reliability, Validity and Association With Trait and Cognitive Impulsivity

Impulsivity is a multifaceted construct central to several forms of psychopathology. Recently, Lynam, Smith, Whiteside, and Cyders (2006) developed the UPPS-P scale, a multidimensional inventory that assesses 5 personality pathways contributing to impulsive behavior: negative urgency, lack of perseverance, lack of premeditation, sensation seeking, and positive urgency. In this study, we aimed (a) to analyze the psychometric properties of a Spanish version of the UPPS-P scale and (b) to explore the relationship between the different dimensions of the UPPS-P scale and conceptually related constructs including trait measures derived from different models of impulsive personality (the Gray's [1987] and Plutchik's [1984] models) and a state measure of cognitive impulsivity, the Delay-Discounting Test ( Kirby, Petry, & Bickel, 1999 ). We administered the UPPS-P scale along with the Sensitivity to Punishment and Sensitivity to Reward Questionnaire ( Torrubia, Avila, Molto, & Caseras, 2001 ), the Plutchik Impulsivity Scale ( Plutchik & Van Praag, 1989 ), and the Delay-Discounting Test to a sample of 150 undergraduate students. Results showed that the Spanish adaptation of the UPPS-P scale have appropriate psychometric properties. Different dimensions of the UPPS-P were differentially associated with predicted conceptually related constructs. We conclude that the Spanish adaptation of the UPPS-P scale is a useful instrument for fine-grained assessment of impulsivity in Spanish-speaking adult population.
