The 34-item Barratt Impulsiveness Scale—Version 1.0 (Barratt, 1985; Patton, Stanford, & Barratt, 1995) includes questions focusing on motor impulsivity (acting without thinking), cognitive impulsivity (making quick cognitive decisions), and future-planning impulsivity (lack of concern about the future). Example items are: “I act on the spur of the moment”, and “I say things without thinking”. Items are answered on a 4-point scale (1 = rarely/never and 4 = almost always/always).
