Dismantling Mindfulness-Based Programs: A Systematic Review to Identify Active Components of Treatment

Objectives

Elucidating the active ingredients of psychological treatments is an important step in the scientific validation of these interventions. Component studies are one way to test which aspects of psychological treatments impact outcomes, or in other words, are the active ingredients of treatment. As research and popular interest in mindfulness-based programs grows, it is important to evaluate the active ingredients of these programs and to continually refine theorized models of the mechanisms of mindfulness. Studying active ingredients may help clarify which elements of mindfulness-based programs are most important for dissemination.

Methods

We conducted a systematic review of component studies of mindfulness-based programs for adults with psychological conditions. PRISMA guidelines for systematic reviews were followed.

Results

Eight component studies were identified. These studies dismantled mindfulness-based stress reduction, mindfulness-based cognitive therapy, unified mindfulness, and core mindfulness processes. The eight studies differed with respect to types of programs and populations studied, yet similarities emerged. Notably, acceptance coupled with awareness and mindfulness meditation training may be two promising active ingredients of these different programs.

Conclusions

Future studies examining mindfulness-based programs should continue to attempt to dismantle active ingredients of treatment and use the findings to update theoretical models of mindfulness.

Mindfulness, acceptance, and emotion regulation: perspectives from Monitor and Acceptance Theory (MAT)

Experiential acceptance-an orientation of receptivity and noninterference with present-moment experiences-is described as central to mindfulness interventions, yet little experimental work has tested acceptance as a mechanism for mindfulness intervention effects. Guided by Monitor and Acceptance Theory (MAT), this review situates acceptance as an emotion regulation mechanism and reviews self-report mindfulness literature showing that attention monitoring skills are only associated with beneficial mental and physical health outcomes when accompanied by acceptance skills. New experimental dismantling work shows that removing acceptance training from mindfulness interventions reduces their efficacy for improving stress, positive emotion, and social relationship outcomes. Overall, converging evidence demonstrates that acceptance is a critical emotion regulation mechanism of mindfulness interventions. This work advances basic research, has translational value, and offers opportunities for future research.
