“…However, one longitudinal study found that rumination (brooding and reflection subscale) did not predict depressive symptoms one year later, when compared to trait mindfulness and while controlling for baseline depression symptoms (Schut & Boelen, 2017 ). Mediation analysis determined that rumination was a significant mediator between maladaptive perfectionisms (De Rosa et al, 2021 ), gratitude (Liang et al, 2020 ), non-judge mindfulness component (two years after) (Petrocchi & Ottaviani, 2016 ), emotional clarity (Vine & Marroquin, 2017 ), overgeneral autobiographical memory (Liu et al, 2017 ), and negative affect (Iqbal & Dar, 2015 ) and depression symptoms.
