RESUMO
The aim of the present study was to test predictions derived from the habit-goal framework of depressive rumination and investigate its relevance to cognitive reactivity-another well-known vulnerability factor to depression. Formerly depressed (FD; n=20) and never depressed (ND; n=22) participants completed self-report measures of rumination, cognitive reactivity, and habitual characteristics of rumination (e.g., lack of awareness, control, intent). A standard mood-induction task was also used to measure cognitive reactivity and an outcome-devaluation task to measure general habit vs. goal-directed behavior control. Habitual characteristics of ruminative thoughts were greater in the FD group and were related to depressive brooding and cognitive reactivity, but not reflective pondering. Reliance on habit on the outcome-devaluation task was strongly correlated with number of depression episodes, although group differences were not observed in general habit vs. goal-directed control. Habitual characteristics of rumination (e.g., greater automaticity) may explain reactivity and persistence of negative thoughts in depression. Habitual behavior control may contribute to inflexible responding and vulnerability for depression episodes.
