The Barratt Impulsiveness Scale—Version 11 (BIS-11) [72], a 30-item self-administered questionnaire, was used to assess impulsivity. The BIS has excellent psychometric properties [73], and contains three factor scores, viz., motor impulsivity (BIS_MI), non-planning (BIS_NP), and attentional impulsivity (BIS_AI), and a total score (BIS_Tot).
