| Summary: | Abstract
BackgroundMindfulness-based interventions (MBIs) are widely used in mental health promotion and treatment. Despite widespread evidence of effectiveness with different populations and delivery modes, there are sparse findings concerning the mechanisms of action in MBIs.
ObjectiveThe objective of this paper was to understand the mediators of the Mindfulness Virtual Community (MVC) intervention, an 8-week, multicomponent, online mindfulness and cognitive-behavioral therapy (M-CBT) intervention, based on a secondary evaluation of 2 randomized controlled trials (RCTs) with student participants.
MethodsMediation analysis, using structural equation modeling, was used to assess direct and indirect relationships between study group (ie, intervention or wait list control) and outcomes. Consistent with the intervention’s theoretical perspective and direct effects paths, a model was specified to evaluate whether mindful nonreactivity, as evaluated by the 5-factor mindfulness questionnaire, mediated the effect of MVC intervention on anxiety and depression (as symptom-driven outcomes), and perceived stress and quality of life (as functional outcomes). The model included additional mediating paths for perceived stress through anxiety and depression, and for quality of life through anxiety, depression, and perceived stress. The model was thereafter extended, adjusting for pre-intervention differences in mindfulness (ie, observing, describing, activity with awareness, nonjudgment, and nonreactivity) facets.
ResultsDirect (nonmediated) effects indicated statistically significant differences at 8 weeks between the MVC and waitlist control (WLC) groups on depression (−1.72; PPPPP
ConclusionsThis research underscores the importance of mindful nonreactivity, depression, and anxiety as key mediators of MVC intervention benefits. |
