Note.

^**p < .01

^*p < .05; MSSD = mean squared successive difference of MIS scores; MIS = aggregate MIS scores (averaged across 10 days of assessment); NU = UPPS-P negative urgency; PU = UPPS-P positive urgency; SS = UPPS-P sensation seeking; LPer = UPPS-P lack of perseverance; LPlan = UPPS-P lack of planning. Correlations from Sample 1 (daily diary sample) are included below the diagonal, whereas correlations from Sample 2 (EMA sample) are included above the diagonal. UPPS-P perseverance (per) and UPPS-P planning (plan) were scored such that higher scores reflect higher perseverance and planning in Sample 2, as opposed to (lack of) perseverance and planning. Ninety-five percent confidence intervals are contained in brackets.

^aCorrelations with MSSD of MIS scores reflect partial correlations after accounting for aggregate MIS scores consistent with Dejonckheere et al. (2019). Sample 1 Level-2 n = 74–76; Sample 2 Level-2 n = 126–147.
