Background: Neural reactivity to dysphoric mood induction indexes the tendency for distress to promote cognitive reactivity and sensory avoidance. Linking these responses to illness prognosis following recovery from Major Depressive Disorder informs our understanding of depression vulnerability and provides engagement targets for prophylactic interventions. Objective: A prospective fMRI neuroimaging design investigated the relationship between dysphoric reactivity and relapse following prophylactic intervention. Remitted depressed outpatients (N=85) were randomized to 8 weeks of either Cognitive Therapy or Mindfulness Based Cognitive Therapy and followed for 2 years to assess future relapse status. Findings: Dysphoric mood challenge evoked prefrontal activation and sensory inhibition. Controlling for number of past episodes and concurrent symptoms, somatosensory inhibition was significantly associated with depression recurrence in a static pattern that was unaffected by prophylactic treatment (HR ·05, 95% CI 0·02โ0·17; p
