Validating the New Remote Hypnotic Induction Profile (rHIP)

Study Overview
=================
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.

Official Title

Conditions

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |

| Active Comparator: HIP First<br>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<br>* Hypnotizability testing in-person vs. by phone.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Reliability of HIP and rHIP test scores | Calculate the correlation between the HIP and rHIP | Through study completion, approximately 2 months. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Hypnotizability and DES | Investigate any correlation between hypnotizability scores and the Dissociative Experiences Scale | Administered upon enrollment, prior to first hypnotizability test | 
| Hypnotizability and Tellegen | Investigate any correlation between hypnotizability scores and the Tellegen Absorption Scale | 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. | Through study completion, approximately 2 months. |
