State rumination predicts inhibitory control failures and dysregulation of default, salience, and cognitive control networks in youth at risk of depressive relapse: Findings from the RuMeChange trial

•We examined rumination about a bothersome unresolved problem in youth with elevated depressive rumination.•Rumination on these problems during an inhibition task predicted inhibitory failures.•Default mode network engagement increased during inhibitory failures in high ruminators.•Cognitive control network engagement increased during rumination.•Exploratory analyzes found more bothersome problems predicted higher left DLPFC activation during rumination.
