The cost of being absent: Is meta-awareness of mind-wandering related to depression symptom severity, rumination tendencies and trauma intrusions?
Abstract
Deng, Li and Tang (2014) reported that depression symptom severity is negatively associated with dispositional mindfulness and importantly, positively associated with zone-outs (mind-wandering without meta-awareness). We replicated and extended their study by exploring possible explanations for these relationships, and by also investigating whether mind-wandering is related to (1) trait rumination subtype-brooding, depressive or reflective, and (2) trauma intrusions-a hallmark PTSD symptom, since both rumination and trauma intrusions strongly correlate with depression. We also explored if dispositional mindfulness-the opposing construct of mind-wandering-mediated these relationships. Two hundred participants completed mindfulness tendency and depression severity measures, counterbalanced with the Sustained Attention to Response Task (SART)-including thought probes to index behavioral mind-wandering (target-error frequency), subjective mind-wandering and meta-awareness-then the rumination style and trauma intrusion frequency measures. Depression scores positively correlated with mind-wandering with and without meta-awareness and with SART target-error rates, and negatively correlated with dispositional mindfulness. Further, trai...Continue Reading
