Chambers et al. (2008) also wrote that "in order to further explore the association between changes in self-rated mindfulness and changes in other measures of affect and executive cognition from T1 to T2, we examined the correlation between change scores on these measures. Of the nine correlations explored, six were found to be significant. Across all cases increases in mindfulness (as assessed by the MAAS) between the two time points were found to significantly correlate with decreased scores on the BDI (r = .49), BAI (r = .28), RRS reflection (r = .36), and increased scores in DSB (r = .31) and PANAS positive affect (r = .37)."

2. What do those correlations mean?
