This model fit the data well, χ2 (130) = 191.6, p < .001; CFI = .93, RMSEA = .034 (90% CI = .022, .044). Significant paths in the model indicated that age was positively related while working memory and reversal learning were negatively related to impulsivity. In addition, impulsivity was positively and strongly related to both risk and problem behaviors. However, problem behaviors were no longer related to risk behavior after controlling for impulsivity. That is, the path from problem to risk behavior was not significant, p = .14. Although Stroop performance (cognitive control) was highly related to working memory performance, none of the other ECF tasks was significantly related to impulsivity.
