About this study

The study aims to examine inter-brain synchrony between patients and therapists over the course of psychotherapy. Twenty patients will undergo a 16-session course of psychotherapy for major depressive disorder. The protocol used will be supportive-expressive psychotherapy (see Luborsky et al., 1995). Participants will also undergo Hamilton depression interviews a week before treatment, before every session and a week after treatment. functional near-infrared spectroscopy (fNIRS) imaging will be used to record brain activity during every other session (sessions 1, 3, 5, 7, 9, 11, 13, 15) as well as during interviews at baseline, on session 8 and at followup. Saliva samples will be collected during the same sessions to measure hormone and cytokine levels during the same sessions. Participants completed questionnaires before and after the study, and before and after each session.

The researchers hypothesized that synchrony will gradually increase over the psychotherapy sessions, and that synchrony in the pre-treatment interview will be lower than in the post-treatment interview.

Read the detailed description

This study centers on a 16-session supportive-expressive treatment protocol for major depression (Luborsky et al., 1995).

The study will last 18 weeks. On weeks 1 and 18 participants will come in to a screening interview preformed by a research assistant. On weeks 2-17 participants will come in to therapy meetings, according to the aforementioned protocol. Every week prior to screening / treatment participants will also undergo a Hamilton depression interview. On weeks 1,2,4,6,8,9,10,12,14,16,18 the researchers will also perform functional near-infrared spectroscopy (fNIRS) imaging and take saliva samples (on weeks 1,9, and 18 - during the Hamilton interview. On other weeks - during treatment). Participants, interviewers (when interviews were assessed) and therapists (when treatment was assessed) underwent fNIRS imaging and provided saliva samples to measure Oxytocin, Cortisol and Cytokine levels. Samples will be tested for levels and subsequently destroyed.

All therapists will be licensed psychologists, and will performing a brief version of Supportive-Expressive therapy (Luborsky et al., 1995). Therapists have all undergone specific training in Supportive-Expressive therapy before being involved in the study. They will also have a group supervision meeting once every two weeks with a therapist who is highly experienced in Supportive-Expressive therapy.

Participants will also complete self-report questionnaires - for some of the questionnaires they may be given the option to complete them online outside of the weekly meeting itself.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change from baseline depression (time frame: Weeks 1,18). 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 NCT06196346, 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.

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 10 Dec 2024; AzTrials last refreshed its copy on 29 Oct 2026.
