Brief summary
The purpose of the study is to determine if hypnotizability can be reliably tested over the phone, without having to see or touch a patient. The scores from a new test for hypnotizability by phone will be compared to the scores from a standard in-person test, to make sure the results are similar.
Interventions
OTHERHypnotizability testing
Hypnotizability testing in-person vs. by phone. All participants will complete both conditions.

Participants not told their hypnotizability score from the first exam prior to completing the second exam. Study personnel performing the second hypnotizability test are masked to the first hypnotizability score. Two separate investigators will test each participant.
Intervention model description
Participants are randomized to first undergo phone-administered testing vs. in-person testing.
