Figure 2. Correlation between Change in Stroop effect and Treatment Engagement and Outcome.

Figure 2

Rank-order whole brain correlations between change in Stroop effect-related activity at post-treatment versus beginning-of-treatment ((post incongruent- post congruent)-(pre incongruent- pre congruent)) and (A) number of cognitive behavioral therapy (CBT) sessions attended (N=26); (B) number of contingency management (CM) prizes received, within group randomized to CM (N=14); (C) percent days of self-reported days of cocaine abstinence during treatment. Blue regions indicate inverse correlations showing lower Stroop-related activity at post- vs. beginning-of-treatment associated with more treatment engagement. Red regions indicate positive correlations showing higher Stroop-related activity at post- versus beginning-of-treatment associated with more cocaine abstinence. Scatter plots show extracted rank order correlations from each significant cluster (see Table 3B). fMRI results are family-wise-error-corrected for multiple comparisons at pFWE<.05.
