Mindfulness is a key component of a growing number of psychological interventions including Acceptance and Commitment Therapy (Hayes et al., 2011), Dialectical Behavior Therapy (Linehan, 1993), Mindfulness-Based Cognitive Therapy (MBCT; Segal, Williams, & Teasdale, 2001), Emotion Regulation Therapy (Mennin & Fresco, 2013), Acceptance-Based Behavior Therapy (Hayes-Skelton, Roemer, & Orsillo, 2013), and the Unified Protocol (Barlow et al., 2010), to name a few. In addition, recent meta-analyses have identified that mindfulness-based interventions (MBIs) are effective treatments for both symptoms of anxiety and depression (e.g., Hofmann et al., 2010, Piet & Hougaard, 2011). Despite the growing evidence for its efficacy, the mechanisms by which MBIs produce their salutary benefits are less well understood (Hawley et al., 2013). The papers described below attempt to tackle this important question in the context of differing samples, types of MBIs, and research methodologies. In doing so, they converge on some important conclusions regarding how MBIs exert their therapeutic effects. First, Michael Moore will present findings from a recent three-armed randomized-controlled trial (MBCT, group relaxation training, & treatment-as-usual). Several potential measures of therapeutic process in MBCT (e.g., decentering, self-compassion, nonjudgmental awareness) will be compared with regard to their specificity in predicting symptom change in MBCT. Second, Colin Bosma will present data from the same trial examining both cognitive and mood reactivity as potential mediators of outcome. Third, David Fresco will present data demonstrating associations between changes in decentering and patterns of functional connectivity in clients receiving Emotion Regulation Therapy (ERT). In a sample of clients suffering from problematic worry, increases in decentering were associated with functional connectivity in the default network, which has been shown to be involved in self-referential processing. Lastly, Joanna Arch will examine acceptance and cognitive defusion as potential session-by-session mediators of outcome in a trial of ACT for anxious cancer survivors. Finally, we are fortunate to have Gregory Feldman, a noted mindfulness and psychopathology researcher, to serve as our discussant.
