Mindfulness, subjective, and psychological well-being: A comparative analysis of FFMQ and MAAS measures

This study investigates the relationships of mindfulness with subjective well-being and psychological well-being through the mediating role of psychological capital. It also compares the Mindful Attention Awareness Scale (MAAS) and the Five Facet Mindfulness Questionnaire (FFMQ) in relation to these outcomes. Using a randomized controlled design, 185 participants from Prolific completed a brief two-week mindfulness intervention, with one pre- and two post-intervention measures. While the intervention effects were limited, the findings reveal that mindfulness is positively and similarly associated with both SWB and PWB, with stronger indirect links to PWB via PsyCap. While both measures of mindfulness had similar relationships with all outcomes, the multidimensional FFMQ offered additional insights, identifying the "describing" facet as particularly influential for both SWB and PWB, informing new potential paths for theorizing and practice.
