Dismantling Mindfulness: Contributions of Attention vs. Acceptance
Study Details
Study Description
Brief Summary
This study addresses NCCAM's request for research that investigates the neuropsychological mechanisms underlying mind-body therapies, and for precise criteria and better delineation of meditation practices.
The purpose of this study is to assess the clinical efficacy and mechanism of action of 2 component practices of "mindfulness meditation", i.e. focused awareness (FA) and open monitoring (OM) in comparison to each other and to the standard package, Mindfulness-Based Cognitive Therapy (MBCT).

Detailed Description
Meditation, particularly mindfulness meditation, is one of the most popular Complementary and Alternative Medicine (CAM) therapies for alleviating emotional stress, depression and anxiety. While standardized meditation-based treatment packages like Mindfulness Based Stress Reduction (MBSR) and Mindfulness-based Cognitive Therapy (MBCT) have reliably shown sustained improvements in emotional disturbances and wellbeing, they contain so many different components and practices that the active ingredient cannot be ascertained. What is commonly called "Mindfulness" meditation is actually comprised of two separate practices: 1) focused awareness practice (FA), and 2) open-monitoring practice (OM). This project aims to create separate 8 week programs for FA and OM meditations, compare their clinical efficacy and investigate their separate mechanisms of action in individuals with clinically significant levels of persistent negative affect and depression. The clinical benefit and mechanism of action of focused awareness (FA) vs open-monitoring (OM) vs MBCT will be examined with a 3-armed randomized control trial of these 8 week interventions. Outcome variables include negative affect (depression, anxiety, stress) and wellbeing. Hypothesized mediating processes include objectively measured attention, emotion regulation and the basic wakefulness on which they depend.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Focused Attention (FA) This 8 week program consists solely of focused attention practices, i.e. selected attention to an object (breath etc) and deselection of other stimuli |
Behavioral: Focused Attention (FA)
|
| Experimental: Open-Monitoring (OM) This 8-week program consists solely of open monitoring practices, or noticing and/or labeling the contents of ongoing experience ( thoughts, body sensations, emotions, seeing, hearing etc) without focusing on or deselecting any stimuli |
Behavioral: Open- Monitoring
|
| Experimental: Mindfulness-Based Cognitive Therapy (MBCT) The 8 week MBCT program follows the 2nd Edition (2012) manual (Segal, Williams, Teasdale) and includes both focused attention and open- monitoring practices |
Behavioral: Mindfulness-Based Cognitive Therapy
