Registry summary

Text and fields below are the sponsor's entries at ClinicalTrials.gov, shown as posted.

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.

Primary outcomes1

Outcomes the sponsor listed as primary.

  1. 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

    Registry description

    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.

Secondary outcomes(3)
  1. Salivary Cortisol

    Time frame · before drug, before session, and 20 minutes after session

    Registry description

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

  2. Heart Rate Variability (HRV)

    Time frame · continuously monitored from time before drug delivery to 20 minutes after session

    Registry description

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

  3. Subjective Ratings of Anxiety and Trust of the Therapist

    Time frame · measured before drug, immediately before session, and after the session

    Registry description

    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.
