About this study

Official title: An Interventional Study to Improve Social Attention in Autistic Spectrum Disorder (ASD): A Brain Computer Interface (BCI) Approach

This study aims to demonstrate that improvements in identification of social clues (and improvement of overall social behaviour) in subjects with ASD can be achieved using social games together with a BCI setup.

The primary goal is to ensure increased rate of responses to joint attention cues.

Intervention Type is a Device (brain computer interface using EEG). Structure: (1) initial eligibility screening (within 1 week after admission), (2) pre-intervention (first week of study, baseline outcome measures and additional evaluations), (3) intervention process (16 weeks), (4) post-intervention (outcome measures and additional evaluations), and (5) follow-up (outcome measures at 6 months).

Read the detailed description

Clinical research has demonstrated that ASD children have deficits in the interpretation of others intentions from gaze-direction or other social attention cues (Baron-Cohen, Baldwin, \& Crowson, 1997).

The purpose of the study is to investigate whether a brain computer interface (BCI) using electroencephalographic (EEG) signals can be used to train social cognition skills (in particular interpretation of gaze direction pointing to objects of interest) in ASD patients and whether this improves clinical symptoms.

The intervention comprehends seven BCI sessions spread over four months. The first four sessions are planned to occur weekly, and the rest monthly. In each session, the subject is asked to identify objects of interest based on the gaze direction of an avatar. The subject response is interpreted from the EEG signal (using the P300 component, as established in our previous work).

What is being measured

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

  1. JAAT_NoFace

    Number of fixations on the target object of the joint attention animation of an avatar after the animation starts (e.g. looking at, pointing at) in the Joint-attention assesment task - JAAT_NoFace with no previous fixation on avatar face.. We will use a new task/realistic game that will challenge the detection of initiation of joint attention cues (from avatars - gaze or pointing). The number of correct responses (to particular objects and not to non-object parts of the scene) will be recorded. We will also record incorrect responses to non-pointing body gestures.

    Measured: 16 weeks, and 6 months after intervention

  2. JAAT_Face

    Number of fixations on the target object of the joint attention animation of an avatar after the animation starts (e.g. looking at, pointing at) in the Joint-attention assesment task - JAAT_NoFace with previous fixation on avatar face.. We will use a new task/realistic game that will challenge the detection of initiation of joint attention cues (from avatars - gaze or pointing). The number of correct responses (to particular objects and not to non-object parts of the scene) will be recorded. We will also record incorrect responses to non-pointing body gestures.

    Measured: 16 weeks, and 6 months after intervention

Secondary outcomes (2)
  1. ATEC - Autism Treatment Evaluation Checklist

    Autism Treatment Evaluation Checklist (ATEC) evaluates the effectiveness of autism treatments - a 1-page form designed to be completed by parents or caretakers. It consists of 4 subtests: I. Speech/Language Communication (14 items, min.0-max.28); II. Sociability (20 items, min.0-max.40); III. Sensory/Cognitive Awareness (18 items, min.0-max.36); and IV. Health/Phys./Behavior (25 items, min.0-max.75). Total score (sum) ranges from min.0-max.179.

    The results reported here correspond to the total ATEC score to be used for comparison at a later date. The lower the score, the fewer the problems.

    Measured: 16 weeks, and Follow-Up (6 months after intervention)

  2. VABS - Vineland Adaptive Behaviour Scale

    The Vineland Adaptive Behaviour Scale (VABS) is a semi-structured interview designed to assess global adaptive functioning, composed by 3 main domains: Communication COM, Daily Living Skills DLS and Socialization SOC. The Adaptive Behaviour Composite ABC (total score) is the sum of the raw scores from the main domains. These are transformed in standard scores (m.=100;std.=15). The higher the score, better is the adaptive behavior. Sparrow, S., Balla, D., \& Cicchetti, D. (1984). Vineland Adaptative Behaviour Scales: Interview edition, Survey form. Circle Pines, MN: American Guidance Service.

    Measured: 16 weeks, and Follow-Up (6 months after intervention)

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?

Yes. Results are posted in the registry (first posted 18 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

JAAT_NoFace (time frame: 16 weeks, and 6 months after intervention). The study lists 2 primary outcomes in all. 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 NCT02445625, 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 18 Feb 2019.
