Does rumination function as a longitudinal mediator between mindfulness and depressive symptoms?
<p>The present study was designed to longitudinally examine the relationships among dispositional mindfulness, rumination, and depressive symptoms in adults and determine whether rumination mediated the expected negative association between mindfulness and depressive symptoms across time. A community sample of 483 New Zealand adults completed self-report measures of mindfulness, rumination and depressive symptoms initially and again after three months and a third time a further three months later. The predicted cross-lag associations were found, and in consequence, the predicted longitudinal mediation was supported in the data as well. That is, rumination mediated the negative association between mindfulness and depressive symptoms. In addition, three of the five facets of mindfulness (acting with awareness, non-judging, and non-reacting) exhibited the longitudinal mediation through rumination to depressive symptoms. The findings of this research suggest that certain aspects of mindfulness function to reduce rumination, which then serve to diminish depressive symptoms.</p>
