The State- and Trait-Level Effects and Candidate Mechanisms of Four Mindfulness-Based Cognitive Therapy (MBCT) Practices: Two Exploratory Studies.
Study Goal
The researchers aimed to explore state- and trait-level effects and potential mechanisms of four Mindfulness-Based Cognitive Therapy (MBCT) practices in a general population.
Results Summary
The study found state-level improvements in self-compassion, mindfulness, and pleasantness of thoughts/emotions/body sensations, but no between-group differences. Trait-level improvements were seen in psychological quality of life and some mechanisms, though again no between-group effects were observed. Changes in mindfulness and self-compassion were linked to better psychological quality of life.

| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | increase | state-level self-compassion, mindfulness, pleasantness of thoughts, emotions, and body sensations | one hundred sixty adults self-selected from the general population | d = 0.27 to 0.86 | state-level effects were demonstrated | #1 |
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | no change | state-level self-compassion, mindfulness, decentering, pleasantness of thoughts, emotions, and body sensations | one hundred sixty adults self-selected from the general population | p = 0.050 to 0.973 | no between-group effects were found | #2 |
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | increase | psychological quality of life and most candidate mechanisms (self-compassion, mindfulness, decentering, interoceptive awareness, attentional control) | one hundred sixty adults self-selected from the general population | d = 0.26 to 0.64 | trait-level effects were demonstrated | #3 |
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | no change | trait-level self-compassion, mindfulness, decentering, interoceptive awareness, attentional control, anxiety, depression, and psychological quality of life | one hundred sixty adults self-selected from the general population | p = 0.080 to 0.805 | no between-group effects were found | #4 |
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | increase | psychological quality of life | one hundred sixty adults self-selected from the general population | r = 0.23 to 0.40 | changes were associated with improvements | #5 |
four mindfulness practices (body scan, mindful movement, breath and body, and befriending) | increase | self-led mindfulness practice | one hundred sixty adults self-selected from the general population | r = 0.18 to 0.23 | changes were associated with improvements | #6 |
OBJECTIVES: The primary aim was to explore state- and trait-level effects and candidate mechanisms of four Mindfulness-Based Cognitive Therapy (MBCT) practices. METHOD: One hundred sixty adults self-selected from the general population were randomized to one of four mindfulness practices: body scan, mindful movement, breath and body, and befriending. Study 1 explored state-level self-compassion, mindfulness, decentering (mechanisms), and pleasantness of thoughts, emotions, and body sensations at multiple time points using two single mindfulness sessions. Study 2 explored trait-level self-compassion, mindfulness, decentering, interoceptive awareness, attentional control (mechanisms), anxiety, depression, and psychological quality of life pre-post 2 weeks of daily practice. RESULTS: In study 1, state-level effects were demonstrated in all candidate mechanisms and outcomes within the whole sample across time points (d = 0.27 to 0.86), except for state decentering. After controlling for pre-scores and additional covariates, no between-group effects were found (p = 0.050 to 0.973). In study 2, trait-level effects were demonstrated in psychological quality of life and most candidate mechanisms within the whole sample (d = 0.26 to 0.64) but no between-group effects were found (p = 0.080 to 0.805). Within the whole sample, after controlling for pre-scores, changes in mindfulness, self-compassion, decentering, and interoceptive awareness (i.e. body listening) were associated with improvements in psychological quality of life (r = 0.23 to 0.40) and self-led mindfulness practice (r = 0.18 to 0.23). CONCLUSIONS: Future research should test the generated hypotheses using well-designed, adequately powered, and theory-driven studies that address universal and specific mechanisms in different populations and contexts.
