Note: Lo IMP = low impulsivity; Hi IMP = high impulsivity; BA = behavioral addictions.

No Risk group = Lo Imp: 0 BA; Single Risk–BA group = Lo IMP: 3+ BA; Single Risk–impulsivity group = Hi IMP: 0 BA; Combined Risk group = Hi IMP: 3+ BA.

Groups sizes = Lo IMP: 0 BA (N = 227); Lo IMP: 1 BA (N = 132); Lo IMP: 2 BA (N = 99); Lo IMP: 3+ BA (N = 146); Hi IMP: 0 BA (N = 121); Hi IMP: 1 BA (N = 76);
