Mindfulness and emotional distress: The role of negatively biased cognition

Mindfulness is a receptive attention to and awareness of events and experiences as they occur. A substantial body of literature supports the usefulness of mindfulness-based approaches for preventing or reducing emotional distress (e.g., depression and anxiety). However, mechanisms by which mindfulness produces these benefits are still being explored. Cognitive theories of emotional disorder implicate negatively biased cognition as a primary source of distress, and the theoretical literature on mindfulness suggests that it may reduce biased thoughts and judgments. Thus, the present research tested a mediation model in which less negatively biased cognition explains the inverse relation between mindfulness and emotional distress. Participants completed multiple standardized measures of trait mindfulness, negatively biased cognition, and emotional distress. The proposed relations between these constructs then were examined using structural equation modeling. Support was found for a partial mediation model, and possible alternative models were ruled out. These findings highlight a previously unidentified cognitive mechanism to explain the relation between mindfulness and reduced emotional distress. Specifically, mindfulness may reduce negative, maladaptive cognitive styles, which in turn may reduce predisposition to emotional disorders.

► Previous research has established that mindfulness reduces emotional distress.
► Negatively biased cognition perpetuates distress and may help explain benefits of mindfulness.
► We tested this proposed mechanism using structural equation modeling.
► Negatively biased cognition partially mediated an inverse link between mindfulness and distress.
► Mindfulness may improve well-being by affecting cognitive content, not just cognitive processes.
