Abstract
OBJECTIVE: Out-of-class mindfulness meditation practice is a health behavior that is considered to be a crucial ingredient in mindfulness-based interventions (MBIs), yet participant adherence to practice recommendations is often inconsistent. Furthermore, MBIs may enhance factors that lead to greater adherence to medical regimens in other contexts. This study examined baseline factors previously found to relate to adherence to medical regimen, MBI-related changes in these baseline factors, and treatment-related factors as predictors of meditation adherence in an 8-week MBI. METHODS: Baseline traits (personality, depressive symptoms, and executive function) were entered into regression models (n = 96) to predict intervention and postintervention out-of-class meditation adherence. Trait changes and treatment-related factors were entered into models to predict postintervention meditation adherence. RESULTS: Baseline conscientiousness (β = 0.33, p = .002), openness (β = 0.23, p = .019), and depressive symptoms (β = 0.19, p = .042) predicted intervention meditation adherence, whereas conscientiousness (β = 0.21, p = .044) and depressive symptoms (β = 0.22, p = .020) predicted postintervention meditation adherence. Although all trait variables except for agreeableness changed significantly pre-to-post intervention, these changes did not predict postintervention meditation adherence. Retreat attendance (β = 0.38, p = .029) and instructor/group-related therapeutic factors collectively predicted postintervention meditation adherence (R2 = 0.21, p = .019). CONCLUSIONS: The identified baseline trait factors could be used to increase adherence in these interventions as a method of increasing their effectiveness. An emphasis on the MBI retreat and social factors during the intervention may be important for participant out-of-class practice postintervention.Trial Registration:ClinicalTrials.govNCT01831362.
