Mindfulness-based cognitive therapy (MBCT) plus treatment as usual (TAU) did not significantly reduce the risk of relapse to major depressive disorder over 12 months compared with cognitive psychological education (CPE) plus TAU or TAU alone among people with at least three previous episodes. The hazard ratio for MBCT versus CPE was 0.88, and for MBCT versus TAU was 0.69, both with confidence intervals crossing 1.0. However, severity of childhood trauma influenced relapse risk: each one-standard-deviation increase in trauma severity raised the hazard ratio to 1.26. Among participants with above-average childhood trauma, MBCT offered significant protection compared with TAU (hazard ratio 0.43) and a non-significant advantage over CPE. For those with below-average trauma, no differences between treatments appeared.
