This study tests for measurement invariance of impulsivity assessed by the Barratt Impulsiveness Scale (BIS) across Black and White adults with cocaine use disorder and examines the association of BIS impulsivity with treatment retention and outcomes. Data from four clinical trials were combined providing a total sample of 302 participants with cocaine abuse/dependence (42% Black, 58% White, 44% female, agemean = 40.22, SD = 9.26). We used multi-group confirmatory factor analyses to test for measurement invariance across race and examined bivariate correlations between BIS impulsivity and treatment retention and outcomes by race. Factor analyses indicated a 22-item, two-factor (motor impulsiveness and nonplanning impulsiveness) brief BIS fit the data best (RMSEA = 0.073 [90% CI: 0.065-0.080]; CFI = 0.904; TLI = 0.893; SRMR = 0.073) and was configural, metric, and scalar invariant across race. Higher motor impulsiveness was associated with higher percentage cocaine negative urines in the overall sample (r = -0.15, p = .01), but this association only remained in the Black subsample when examined across race (r = 0.28, p < .001). Higher motor impulsiveness was also associated with increased days abstinent from cocaine in the Black subsample only (r = 0.28, p < .001). Nonplanning impulsiveness was associated with lower percentage of treatment days abstinent from cocaine in the White subsample only (r = -0.16, p = .045). These findings 1) provide evidence for a 21-item, two-factor brief BIS that is invariant across Black and White adults with cocaine use disorder, and 2) suggest that BIS impulsivity may be associated with poorer cocaine treatment outcomes among White but not Black adults.
