Impulsivity was assessed using the Barratt Impulsiveness Scale—Version 11 (BIS-11) [67], which is a 30-item self-administered tool with excellent psychometric properties [68]. The impulsivity scores consisted of three factors: motor impulsivity (BIS_MI), non-planning (BIS_NP), and attentional impulsivity (BIS_AI), and a total score (BIS_Tot).
