About this trial
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.

Treatments tested in this trial
Mindfulness Meditation
BehavioralParticipants in the mindfulness meditation condition will listen to a 20minute guided mindfulness meditation practice that holds the breath and body as the object of meditation.
Self-hypnosis
BehavioralParticipants in self-hypnosis will listen to a 20-minute audio-guided hypnosis practice with an induction phase, followed by suggestions tailored towards shifts in affect and decentering, and then a re-alerting with post-hypnotic suggestions phase.
Attention Control
Other interventionControl participants will listen to a 20-minute natural history recording which was chosen as past research has found that individuals who listen to it report this to be a neutral, but relaxing passage, and it has been used as an effective control condition in previous research.
