as "being conscious of the risk of the behavior but acting anyway" The questionnaire was constructed through factor analysis to contain items that most highly loaded on impulsiveness and venturesomeness. The EIS is a widely used and well-validated measure. Dickman Impulsivity Inventory The Dickman Impulsivity Inventory was first developed in 1990 by Scott J. Dickman. This scale is based on Dickman's proposal that there are two types of impulsivity that are significantly different from one another. This includes functional impulsivity which is characterized by quick decision making when it is optimal, a trait that is often considered to be a source of pride. The scale also includes dysfunctional impulsivity which is characterized by making quick decisions when it is not optimal. This type of impulsivity is most often associated with life difficulties including substance abuse problems and other negative outcomes. This scale includes 63 items of which 23 are related to dysfunctional impulsivity, 17 are related to functional impulsivity, and 23 are filler questions that relate to neither construct. This scale has been developed into a version for use with children as well as into several languages. Dickman showed there is no correlation between these two tendencies across individuals, and they also have different cognitive correlates. UPPS Impulsive Behavior Scale The UPPS Impulsive Behavior Scale is a 45-item self-report questionnaire that was designed to measure impulsivity across dimensions of the Five Factor Model of personality. The UPPS includes 4 sub-scales: lack of premeditation, urgency, lack of perseverance, and sensation-seeking. UPPS-P Impulsive Behavior Scale (UPPS-P) is a revised version of the UPPS, including 59 items. It assesses an additional personality pathway to impulsive behavior, Positive Urgency, in addition to the four pathways assessed in the original version of the scale: Urgency (now Negative Urgency), (lack of) Premeditation, (lack of) Perseverance, and Sensation Seeking UPPS-P short version (UPPS-Ps) is 20-item scale that evaluates five different impulsivity facets (4 items per dimension). UPPS-R Interview is a semi-structured interview that measures the degree to which individuals exhibit the various components of impulsivity assessed by the UPPS-P. Lifetime History of Impulsive Behaviors Lifetime History of Impulsive Behaviors (LHIB) is a 53-item questionnaire designed to assess lifetime history of impulsive behavior (as opposed to impulsive tendencies) as well as the level of distress and impairment associated with these behaviors. The assessment battery was designed to measure the following six dimensions: (a) impulsivity, (b) sensation seeking, (c)
