Session Abstract: Impulsivity is the tendency to act with little forethought, and has a close association with substance use disorders (SUDs), especially among military veterans. However, the nature and effects of Impulsivity differs across groups of veterans. This may be a function of military cohort, which differ not only in terms of age but also in terms of the wars and other military conflicts with which the veterans were engaged. However, there is little empirical research on this. In this study, we examined the invariance of a multifaceted scale of Impulsivity, the Urgency, Premeditation, Perseverance, Sensation Seeking and Positive Urgency (UPPS-P) scale, across three adult male veteran cohorts (Vietnam-era, post-Vietnam-era, and Operation Enduring Freedom/Operation Iraqi Freedom) seeking treatment for SUDs (N = 321) using multigroup confirmatory analysis with the alignment method. Results suggest that the UPPS-P is non-invariant, with Sensation Seeking and Perseverance in particular differing across cohorts. These findings do not support clinical comparisons of impulsivity across veteran cohorts with SUDs where impulsivity is clinically relevant, at least when measured by the UPPS-P.
