- 소개/요약Mindfulness-based interventions (MBI) might improve the controllability of mind-wandering (MW), that is, the ability to decrease MW frequency, to notice MW, and to shift attention from MW. This study investigated whether such controllability of MW mediates the effect of the mindfulness-based intervention (MBI) on depression. Since the MBI, which instructs participants to be aware of the occurrence of, and their engagement in, MW, might bias self-reports of MW, a measurement method that does not rely on subjects' verbal report is needed. Therefore, we estimated MW intensity using one-second electroencephalogram (EEG) samples and a machine learning model developed previously. We recorded EEG before and after MBI, and observed fluctuations in mind-wandering during a 14-minute meditation and quantified the three types of MW trait. The magnitude of the change of depressive symptom and ability to shift attention from MW were correlated. This MW trait is a plausible mediator between MBI and depression.
