Validating the New Remote Hypnotic Induction Profile (rHIP)

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.

Treatment and study plan

Hypnotizability testing

Other

Hypnotizability testing in-person vs. by phone. All participants will complete both conditions.

Primary outcomes

  1. Reliability of HIP and rHIP test scores

    Time frame: Through study completion, approximately 2 months.

    Calculate the correlation between the HIP and rHIP

Secondary outcomes

  1. Hypnotizability and DES

    Time frame: Administered upon enrollment, prior to first hypnotizability test

    Investigate any correlation between hypnotizability scores and the Dissociative Experiences Scale

  2. Hypnotizability and Tellegen

    Time frame: Administered upon enrollment, prior to first hypnotizability test

    Investigate any correlation between hypnotizability scores and the Tellegen Absorption Scale

  3. Complications with phone-administered test

    Time frame: 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.
