“…It is a 30-item questionnaire that measures three different components of impulsiveness: motor impulsiveness (BIS-M), which reflects the tendency to act without thinking; cognitive impulsiveness (BIS-C), characterised by making quick cognitive decisions on the spur of the moment; and non-planning impulsiveness (BIS-NP), which reflects a present orientation and a lack of planning for the future. The reliability and validity of the BIS have been repeatedly demonstrated in a variety of languages (Fossati, Di Ceglie, Acquarini, & Barratt, 2001;Oquendo et al, 2001;Patton, Stanford, & Barratt, 1995;Someya et al, 2001). …”
