Testing the Hypnotizability of Healthy VolunteersNCT04058483
Validating the New Remote Hypnotic Induction Profile (rHIP)
A study testing Hypnotizability testing in people with Testing the Hypnotizability of Healthy Volunteers, run by Stanford University at 1 site in United States.
Trial 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. Read more about this study

About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hypnotizability testingOther
Hypnotizability testing in-person vs. by phone. All participants will complete both conditions.
| Study group | Role | What they receive |
|---|---|---|
| HIP First | Active comparator | 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. Receives: Other: Hypnotizability testing |
| rHIP First | Active comparator | 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. Receives: Other: Hypnotizability testing |
What is being measured
The primary outcome is the main question the study is designed to answer.
Reliability of HIP and rHIP test scores
Calculate the correlation between the HIP and rHIP
Measured: Through study completion, approximately 2 months.
Secondary outcomes (3)
Hypnotizability and DES
Investigate any correlation between hypnotizability scores and the Dissociative Experiences Scale
Measured: Administered upon enrollment, prior to first hypnotizability test
Hypnotizability and Tellegen
Investigate any correlation between hypnotizability scores and the Tellegen Absorption Scale
Measured: Administered upon enrollment, prior to first hypnotizability test
Complications with phone-administered test
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.
Measured: Through study completion, approximately 2 months.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Reliability of HIP and rHIP test scores (time frame: Through study completion, approximately 2 months.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04058483, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2019.
