Note. EQ= Experiences Questionnaire, TMS= Toronto Mindfulness Scale, HRSD T2 = Hamilton Rating Scale for Depression, randomization session (pre-treatment). Group = Mindfulness Based Cognitive Therapy (MBCT), Medication, Placebo. Δ = standardized residualized change in mediator variable from randomization to post treatment (i.e., eight weeks). All analyses use depression severity (HRSD T3 6 months) as the outcome.
