Measurement invariance of the Barratt Impulsiveness Scale across black and white adults with cocaine use disorder.

ABSTRACT: 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, age_mean = 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:
