Note. For sex D1, female/other = 0, male = 1. For sex D2, female/male = 0, other = 1. For race, 0 = non-White, 1 = White. Age is calculated in years. SCT = sluggish cognitive tempo; ADHD = attention deficit/hyperactivity disorder; I = inattention; H/I = hyperactive/impulsive. A bonferroni correction was used based on the total number of regressions used. *p = (.05/5) = .01. Overall model statistics are presented from the original data set which included a planned missingness design. The following are the range of F values across the 40 imputed data sets (p < .0xx for all models across all imputations): Reward valuation: F(8, 4676) = 47.53 – 87.96; Reward expectancy: F(8, 4676) = 75.33 – 96.11; Willingness to work: F(8, 4676) = 47.66 – 48.13; Initial response: F(8, 4676) = 200.32 – 207.47; Sustained response: F(8, 4676) = 57.33 – 70.71.
