There was no significant correlation between BDI-II scores and memory decay for the story free-recall test ( r = −0.05, p = 0.7), but the (negative) correlation between these variables approached significance for the paired associates task ( r = −0.26, p = 0.052).
However, this correlation did not reach statistical significance ( r = −0.21, p = 0.31).
16 , 17 We observed that the correlations between memory strength and TST and % SWS generally held across the entire sample, even if the separate analyses for low- and elevated BDI groups often failed to reach statistical significance, likely due to the small sample sizes.
