About this study
The study will examine the efficacy of a feedback-based treatment applying eye-tracking (Gaze-Contingent Music Reward Therapy) to change attention and gaze patterns associated with angry faces relative to a response-time-based attention bias modification treatment applying the dot-probe task and a control group.
Read the detailed description
The study will recruit veterans with posttraumatic stress disorder (PTSD) due to a trauma acquired during military service. A compatibility check and initial filtering will happen via phone call, using basic symptom questionnaires for self-report and initial examination of exclusion criteria.
This study has four phases:
- Clinical Assessment - Participants who pass the initial filtering and express a desire to participate in the study will be invited to a structured clinical interview during which clinical and practical inclusion and exclusion criteria will be examined by an independent evaluator (a clinical psychologist). After an explanation about the study and provision of signed informed consent from the participant, the clinical interview (CAPS-5 and MINI) will be conducted and self-report questionnaires will be completed:
- Post-trauma Checklist (PCL) - PTSD symptoms
- Patient Health Questionnaire (PHQ) - Depression Symptoms
- Attention Bias Questionnaire (ABQ) - Attention Patterns
- Attention Control Scale (ACS) - Attention Control
- Attention bias measurement - participants will perform computerized tasks aimed to measure their attention bias prior to treatment.
- Free viewing of 30 matrices each with 16 faces (8 with neutral facial expression and 8 with angry facial expression) while monitoring gaze location with passive eye-tracking technology - duration of this assessment is about 15 minutes.
- Attention bias measurement using a dot-probe task in which two faces are presented on the screen and replaced by an arrow pointing right or left, and the participant has to indicate the arrow's direction by pressing a key - duration of the task is about 5 minutes.
- Generic Flanker attention task, in which a middle arrow is presented with additional arrows to the right and left (for example <<><< or >>>>>) and the participant is asked to identify the direction of the middle arrow by pressing a key - duration of the task is about 5 minutes.
- Attention Training - Next participants will be randomly assigned to one of three groups.
- 8 sessions of Gaze Contingent Music Reward Therapy (GC-MRT) - In every session, the participant chooses music to which to listen and is then asked to view matrices of 16 faces as described above. The music plays when the participant views neutral faces and stops when viewing angry faces - each meeting lasts about 20 minutes.
- 8 sessions of Attention Bias Modification Treatment based on a dot-probe task described above with one difference: While in the assessment task the probe location is counterbalanced at neutral and angry faces locations, in the treatment task the arrow always appears at the neutral face location - each session takes about 20 minutes.
- Control group in which participants are exposed to the same procedure as GC-MRT but the music will play continually without contingency to participant's gaze.
- Post-Training Assessment and Measurements - After the 8 treatment sessions, participants will undergo another clinical interview and the same questionnaires and attention assessment tasks similar to those conducted before the treatment. The clinical interview, questionnaires, and attention measurements will occur again after three months from the end of treatment (follow-up).
- NOTE: As a direct result of the ongoing war in Israel the study has encountered serious difficulties in veteran-patients recruitment. First, many veterans were called into active duty since October 7th, 2023, limiting their availability for treatment/research. Second, with the war, numerous new treatment options have become available for veterans with PTSD, making it extremely difficult to recruit patients into a trial.
To date (March 18, 2025), 113 (target n=150) veterans have enrolled in the study and started treatment. Blinded group sizes from stratified randomization thus far stand at 39, 38, and 36.
Given this situation, we are forced to terminate the study early on June 1st, 2025. We will enroll as many additional participants as possible until this end-date.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Gaze-Contingent Feedback TrainingBehavioural
Feedback according to participants' viewing patterns, in order to modify their attention away from threat face stimuli.
Attention Bias ModificationBehavioural
Attention training via repeated trials of a dot-probe task intended to direct attention away from threat stimuli using threat and neutral face stimuli.
Non-Contingent Feedback TrainingBehavioural
Participants listen to a musical track they chose while viewing the face matrices. The music is played throughout and is not contingent upon gaze behavior.
| Study group | Role | What they receive |
|---|---|---|
| Gaze-Contingent Feedback Training | Experimental | In the task, 30 different matrices, each consisting of 16 faces, will be presented. Each matrix includes 8 angry faces and 8 neutral, 8 women and 8 men, and the locations are counterbalanced between matrices. The participants are asked to view the matrices in any way they choose, and the eye-tracking camera records their viewing location relative to the stimuli presented on the screen. At the beginning of each training session, the veteran will choose to which music he would like to listen during the 12-minute session from a diverse list of music. After calibrating the eye-tracking technology, the veteran will be instructed to view the matrices of faces as he chooses, as described above in the assessment task. The music chosen by the veteran will play only when s/he is looking at neutral faces and it will stop when s/he looks at threatening faces. Receives: Behavioral: Gaze-Contingent Feedback Training |
| RT-Based Attention Bias Modification | Active comparator | The task consists of 160 trials. Each trial begins with a centrally-presented fixation cross (+), on which the participant is asked to focus for 500ms. When it disappears, two stimuli will be presented 1.5cm above and below the previous fixation cross for 500ms. After the stimuli disappear, a target probe (right- or left-pointing arrowhead) will appear in place of one of the stimuli, and the participant will be asked to indicate which target probe is presented by pressing the respective key. The target probe will remain on the screen until the participant's response, after which a new trial will begin.
Participants are instructed to identify the probe type as quickly and accurately as possible.
In the training task, all of the target probes will appear in the neutral face location. Thus, over multiple trials, learning occurs that the threatening face predicts the location of the target probe, thereby achieving the desiring change in attention patterns. Receives: Behavioral: Attention Bias Modification |
| Non-Contingent Feedback Training | Placebo comparator | This condition is based on the aforementioned eye-tracking task with a fundamental change - The music chosen by the veteran will play continuously without any reinforcement for looking at threat or neutral faces. Receives: Behavioral: Non-Contingent Feedback Training |

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Gaze-Contingent Feedback Training, Attention Bias Modification and Non-Contingent Feedback Training in people with Posttraumatic Stress Disorder, run by Tel Aviv University at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 8 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Due to the war that is taking place in Israel since October 7, 2023 and the high rates of active army reserve service among the population of the study.). Results are not available in the source record.
