Validating the New Remote Hypnotic Induction Profile (rHIP)

Not Applicable

Completed

• Conditions: Testing the Hypnotizability of Healthy Volunteers
• Interventions: Other: Hypnotizability testing

• Registration Number: NCT04058483
• Lead Sponsor: Stanford University

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.

Arm && Interventions

Group	Intervention	Description
HIP First	Hypnotizability testing	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.
rHIP First	Hypnotizability testing	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.

Primary Outcome Measures

Name	Time	Method
Reliability of HIP and rHIP test scores	Through study completion, approximately 2 months.	Calculate the correlation between the HIP and rHIP

Secondary Outcome Measures

Name	Time	Method
Hypnotizability and DES	Administered upon enrollment, prior to first hypnotizability test	Investigate any correlation between hypnotizability scores and the Dissociative Experiences Scale
Complications with phone-administered test	Through study completion, approximately 2 months.	Researchers will recored the % of participants who reported technical or practical difficulties with the phone-administered test including difficulty hearing, understanding the instructions, getting interrupted during the test, or others.
Hypnotizability and Tellegen	Administered upon enrollment, prior to first hypnotizability test	Investigate any correlation between hypnotizability scores and the Tellegen Absorption Scale
