Does the Five Facet Mindfulness Questionnaire measure what we think it does? Construct validity evidence from an active controlled randomized clinical trial.

Psychological Assessment October 13, 2015 Simon B. Goldberg, Joseph Wielgosz, Cortland J. Dahl et al. 180 citations

A randomized trial with 130 participants tested whether the Five Facet Mindfulness Questionnaire (FFMQ) validly measures dispositional mindfulness. The study included three groups: mindfulness-based stress reduction (MBSR), an active control condition (Health Enhancement Program, HEP) that did not teach mindfulness meditation, and a waitlist control. At baseline, FFMQ facets correlated with measures of psychological symptoms and well-being, providing partial evidence for convergent validity. FFMQ scores increased for MBSR relative to the waitlist, but they also increased for HEP relative to the waitlist, and MBSR and HEP did not differ from each other. The FFMQ thus failed to show discriminant validity, raising questions about its ability to specifically measure mindfulness.

Long-term mindfulness training is associated with reliable differences in resting respiration rate

Scientific Reports June 7, 2016 Joseph Wielgosz, Brianna S. Schuyler, Antoine Lutz et al. 124 citations

Long-term mindfulness meditation practitioners have slower baseline respiration rates than non-meditators, and more intensive retreat practice—but not routine daily practice—is linked to slower breathing, independent of age, gender, and body measures like height, weight, and BMI. Full days of meditation did not immediately change baseline respiration, suggesting the effects are long-term rather than acute. These findings point to stable, generalized changes in respiration from sustained mindfulness training.
