Inter-Brain Synchrony in Psychotherapy for Test Anxiety

Study Overview
=================
Brief Summary
-----------------
The study aims to examine inter-brain synchrony between patients and therapists over the course of psychotherapy. Eight patients underwent a 6-session course of psychotherapy for test anxiety including Cognitive Behavioral Therapy (CBT) and imagery work, following an existing protocol (see Prinz et al., 2019), as well as a pre- and post- treatment interview (with different interviewers). The researchers used functional near-infrared spectroscopy (fNIRS) imaging to record brain activity during both interviews and sessions 1, 3, and 5, and collected saliva samples to measure hormone 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, that synchrony in the pre-treatment interview will be lower than in the post-treatment interview, and that synchrony would be correlated with increases in Oxytocin.

Detailed Description
-----------------
This study centers on a short-term 6-session imagery-based treatment protocol for Test anxiety (Developed by Prof. Eshkol Rafaeli who is a collaborator on the study, with colleagues at the University of Trier; for the full protocol, see www.osf.io/hraqd). The protocol integrates traditional cognitive behavioral and imagery techniques; each session is also followed by some homework assignment, aimed at practicing the contents of the session and/or preparing for the next one. The study lasted 8 weeks. On weeks 1 and 8 participants came in to a screening interview preformed by a research assistant. On weeks 2-7 participants came in to therapy meetings, according to the aforementioned protocol. On weeks 1,2,4,6,8 the researchers also performed functional near-infrared spectroscopy (fNIRS). imaging and took saliva samples. Participants, assessors (in assessment sessions) and therapists (in treatment sessions) underwent fNIRS imaging and provided saliva samples to measure Oxytocin and Cortisol levels. Samples were tested for hormonal levels and subsequently destroyed. The study was an exploratory study, with the same therapist, who was a licensed clinical psychologist, treating all patients. He received supervision from an experienced psychologist with long experience employing cognitive-behavioral and experiential treatment methods. Preliminary questionnaires. (a) Test Anxiety Inventory (b) Young Schema Questionnaire (YSQ-3) to assess early maladaptive schemas; (c) Ten Item Personality Inventory (TIPI) to assess Big-5 characteristics; (d) Schema Mode Inventory (SMI-2) to assess schema modes ; (e) Adult Attention Deficit Hyperactivity Disorder (ADHD) Self Report Scale; (f) Inventory of Interpersonal Problems (IIP) to assess interpersonal problems; (f) General Anxiety Disorder 7-item (GAD7) scale to assess anxiety symptoms; (g) Mindset questionnaire; (h) Patient Health Questionnaire (PHQ9) to assess depression symptoms; (i) Relationship Quality (RQ) to assess attachment; (j) demographic questionnaire; (k) Trauma questionnaires - The life event and Post Traumatic Stress Disorder checklists for the Diagnostic and Statistical Manual (DSM-5) and the Adverse Childhood Experiences Scale .

Design Details

Primary Purpose: Basic Science
Intervention Model: Single Group Assignment
Interventional Model Description: The study was designed to examine changes in inter-brain synchrony over the course of standard psychotherapy, and not treatment effectiveness. As such, a single group design was deemed adequate.
Masking: None (Open Label)

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline State Test Anxiety | A six-item self-report questionnaire designed to measure test anxiety, evaluation apprehension and low efficacy (Lawrence & Williams, 2013). Change was defined as the difference between State Test Anxiety at week 7 and at week 2, and a successful outcome would be State Test Anxiety being lower at week 7 than at week 2. The scale is comprised of 6 items scored between 0 and 6, with the scale value being the mean of the items and as such also ranging between 0 and 6, with higher values representing more anxiety (i.e., more symptoms). | Weeks 2,7 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from baseline Test Anxiety Inventory | A 20-item questionnaire measuring test anxiety (Spielberger, 1980). Change was defined as the difference between Test Anxiety Inventory values at week 1 and at week 8, and a successful outcome would be Test Anxiety Inventory being lower at week 8 than at week 1. Each item is scored between 1 and 4 and the scale value is calculated by summing the items, such that the scale ranges between 20 and 80, with high values representing more anxiety (i.e., more symptoms). | Weeks 1,8 |
