Validating the New Remote Hypnotic Induction Profile (rHIP)

October 30, 2019 updated by: Jessie Kittle, Stanford University

A Randomized Trial Validating the New Remote Hypnotic Induction Profile (rHIP) Against the Existing Hypnotic Induction Profile (HIP)

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: HIP First
Participants randomized to perform the in-person hypnotizability test first. This will be followed within 1 week with the by-phone rHIP test performed by a second, randomly-assigned investigator.
Other: Hypnotizability testing
Hypnotizability testing in-person vs. by phone. All participants will complete both conditions.
Active Comparator: rHIP First
Participants randomized to perform the by-phone hypnotizability test first. This will be followed within 1 week with the in-peron HIP test performed by a second, randomly-assigned investigator.
Other: Hypnotizability testing
Hypnotizability testing in-person vs. by phone. All participants will complete both conditions.
