The present research broadens the understanding of the multidimensional nature of impulsivity by investigating the validity of a German adaptation of the UPPS scale of impulsivity (Whiteside & Lynam, 2001). Two studies utilizing paper-pencil and computerized administration replicated the internal structure of the UPPS, provided evidence for convergent and discriminant validity utilizing self- and peer-reports, demonstrated incremental validity for the UPPS scale over the respective personality facets, and investigated the relationships between self-reported impulsivity and behavioral measures including perceptual speed and response latencies. Taken together, results not only confirm the reliability and validity of the German UPPS scale but also prove its benefit in predicting relevant criteria beyond well-established personality questionnaires. Significant but weak correlations with behavioral measures of cognitive aspects of impulsivity were particularly observed for (lack of) Premeditation and (lack of) Perseverance.
