The Effects and Mechanisms of Brief Mindfulness Meditation and Hypnosis for Pain

The aim of this study is to determine the effects and mechanisms of 1 x 20-min training in mindfulness meditation and self-hypnosis relative to an inert control. Participants will be randomly assigned to condition. The dual primary outcomes will be pre- to post-training changes in current pain intensity and pain unpleasantness. The active treatments are hypothesized to produce greater reductions in pain outcomes than the control. It is also hypothesized that change in mindfulness will be a mediator specific to mindfulness meditation, while change in affect and decentering will be mediators of the hypnosis condition. Moderators of response will also be explored.
