Construct Validity of the Five Facet Mindfulness Questionnaire in Meditating and Nonmeditating Samples

Assessment February 29, 2008 Ruth A. Baer, Gregory T. Smith, Emily Lykins et al. 2,933 citations

Mindfulness as measured by self-report includes five component skills: observing, describing, acting with awareness, nonjudging of inner experience, and nonreactivity to inner experience, assessed with the Five Facet Mindfulness Questionnaire (FFMQ). The authors examined the construct validity of the FFMQ in experienced meditators and nonmeditating comparison groups. Most mindfulness facets were significantly related to meditation experience and to psychological symptoms and well-being. The relationship between the observing facet and psychological adjustment varied with meditation experience. Several facets independently predicted well-being and mediated the relationship between meditation experience and well-being, supporting the FFMQ's construct validity in these samples.

What defines mindfulness-based programs? The warp and the weft

Psychological Medicine December 29, 2016 Rebecca Crane, Judson A. Brewer, Christina Feldman et al. 861 citations

A framework defines essential characteristics of mindfulness-based programs (MBPs) like MBSR and MBCT, distinguishing them from other interventions. MBPs draw from contemplative traditions, science, medicine, psychology, and education; are grounded in a model addressing causes of human distress and pathways to relief; foster present-moment focus, decentering, and an approach orientation; cultivate qualities such as joy, compassion, wisdom, equanimity, and self-regulation; and involve sustained intensive meditation training, experiential inquiry, and exercises. The framework aims to support clarity for systematic research and maintain integrity as MBPs expand into healthcare, education, criminal justice, and workplaces.

Mindfulness‐Based cognitive therapy for prevention of recurrence of suicidal behavior

Journal of Clinical Psychology December 9, 2005 J. Mark G. Williams, Danielle S. Duggan, Catherine Crane et al. 235 citations

Once suicidal thoughts emerge in depression, they tend to return whenever sad mood reappears, part of a suicidal mode of mind. This article reviews how mindfulness-based cognitive therapy (MBCT) may prevent reactivation of that suicidal mode. MBCT combines mindfulness meditation with cognitive therapy, training participants to observe moment-by-moment experience with nonjudgmental acceptance. This helps people see thoughts as mental events rather than facts, a skill called metacognitive awareness. A case example illustrates how mindfulness skills develop and relate to cognitive processes fueling suicidal crises. Pilot work suggests MBCT is a promising intervention for those with past suicidal ideation; an ongoing controlled trial will provide further evidence.

Competence in Teaching Mindfulness-Based Courses: Concepts, Development and Assessment

Mindfulness September 21, 2011 Rebecca S. Crane, Willem Kuyken, J. Mark G. Williams et al. 232 citations

Interest in Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT) has grown rapidly in the UK, prompting health, education, and social work practitioners to develop competencies as mindfulness-based teachers. This has raised fundamental questions about training processes, standards, and competence assessment. The paper examines how competencies are addressed in secular mainstream contexts, presents a framework for how teaching competencies develop in trainees, and reviews current assessment methodologies. The authors argue for continued international dialogue among mindfulness-based trainers and teachers to build a robust professional context for future teachers.

Training Teachers to Deliver Mindfulness-Based Interventions: Learning from the UK Experience

Mindfulness April 26, 2010 Rebecca S. Crane, Willem Kuyken, Richard P. Hastings et al. 205 citations

Mindfulness-based approaches, supported by several randomized controlled trials, help prevent depressive relapse and recurrence, and are recommended by the UK's National Institute for Health and Clinical Excellence for use in the National Health Service. These approaches also appear helpful for anxiety disorders and chronic physical health problems, with growing interest in applying them to personality disorders, substance abuse, and eating disorders. The authors review the UK context, outline criteria for teacher competence and training steps, and discuss challenges and future directions for ensuring evidence-based mindfulness approaches are available in health care and other settings.

Efficacy and Moderators of Mindfulness-Based Cognitive Therapy in Difficult-to-Treat Depression: A Systematic Review and Individual Participant Data Meta-Analysis

Psychotherapy and Psychosomatics June 12, 2026 Thorsten Barnhofer, Maria Niemi, Johannes Michalak et al. 1 citation

For adults with difficult-to-treat depression—those who have not responded to prior treatments, have treatment-resistant depression, or have a chronic course—mindfulness-based cognitive therapy (MBCT) is likely superior to usual care, reducing depressive symptoms by a standardized mean difference of -0.40 at post-treatment and -0.41 at medium-term follow-up. There was a 92% and 85% probability, respectively, that these benefits exceeded a minimal important difference. However, MBCT did not show clear superiority over other active psychosocial interventions, and no robust moderators of outcome were identified across baseline severity, chronicity, or comorbidity.
