Outcome Measures
Primary Outcomes (3)
Pain unpleasantness
Numerical rating scale in response to exposure to a cold pressor task.
Change from Experimental Session 1 (Day 1) to Experimental Session 5 (Day 5)
Pain intensity
Numerical rating scale in response to exposure to a cold pressor task.
Change from Experimental Session 1 (Day 1) to Experimental Session 5 (Day 5)
Pain tolerance

Study Arms (2)
Mindfulness Meditation
EXPERIMENTALParticipants in this arm will complete five, 20-minute mindfulness meditation sessions delivered over consecutive days.
Clinical Hypnosis
ACTIVE COMPARATORParticipants in this arm will complete five, 20-minute clinical hypnosis sessions delivered over consecutive days.
Interventions
Participants in the mindfulness meditation condition will practice a breath and body focused meditation.
Participants in clinical hypnosis will be guided in a hypnosis practice with suggestions tailored towards shifting pain appraisals.

We will make available to interested researchers a data file containing the de-identified data used for each published article at the time that the article is accepted for publication. The data will be de-identified to remove any variables from which it would be possible to identify any individual participants. Specifically, we will create a data file that includes all of the variables used in any published article and a list of the variables in the data file (along with their variable labels) and email to investigators who request the data a copy of: (1) the published article (which will describe the source of the data); (2) the variable list/variable labels; and (3) a copy of the data set (as an SPSS.sav file).
