About this study

Official title: Physiologic Correlates of Perceived [Therapist] Empathy and Social-Emotional Process During Psychotherapy: Testing Oxytocin in a Cross-Over Design Pilot Study

Subjects-currently in outpatient mental health care--will participate in 2 psychotherapy sessions, one with oxytocin spray and one with placebo spray. Sessions will be videotaped, and cortisol and heart rate will be measured. We hypothesize that oxytocin will have positive benefits on nonverbal behavior in the therapy session, as well as have positive effects on subjective anxiety, cortisol and heart rate.

  • Intranasal oxytocin then placeboDrug

    Participant received a single dose of 40 IU intranasal oxytocin at the first psychotherapy session, and received a similar dose of intranasal placebo spray at the second session.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Verbal and Nonverbal Behavior in Therapy Session: Effects of Drug

    Videotapes of 2 therapy session (PBO/OT) were reviewed by blinded raters to determine differences in two treatments. There were nine aspects analyzed using the Ethological Coding System for Interviews: eye contact, affiliation, submission, prosocial, flight, assertion, displacement, relaxation, and gesture.

    Measured: videotapes of session were reviewed and scored 1-3 months after the patient completes the study

Secondary outcomes (3)
  1. Salivary Cortisol

    Salivary cortisol will be measured after the treatment, and before, during and after the therapy session.

    Measured: before drug, before session, and 20 minutes after session

  2. Heart Rate Variability (HRV)

    HRV will be measured before, during and after the therapy session.

    Measured: continuously monitored from time before drug delivery to 20 minutes after session

  3. Subjective Ratings of Anxiety and Trust of the Therapist

    Patient will fill out ratings of subjective anxiety (STAI), mood and energy (PANAS), and trust (Likert scale) in the therapist before and after the session.

    Measured: measured before drug, immediately before session, and after the session

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

What does the primary outcome measure?

Verbal and Nonverbal Behavior in Therapy Session: Effects of Drug (time frame: videotapes of session were reviewed and scored 1-3 months after the patient completes the study). 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 NCT01081249, which also lists 2 linked publications.

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.
