What is being measured

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

  1. Changes of total scores of Social Responsiveness Scale

    Social Responsiveness Scale can measure the autism clinical severity with the range from 65-260. The lower scores stand for better social responsiveness.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  2. Changes of total scores of Repetitive Behavior Scale-Revised

    Repetitive Behavior Scale-Revised is a questionnaire that focuses on repetitive behavior. The score ranges from 0-129. The lower scores stand for lower repetitive behavior.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

Secondary outcomes (12)
  1. Changes of total scores of Emotional Dysregulation Inventory

    Emotional Dysregulation Inventory is a parents' report questionnaire for emotional dysregulation. The score ranges from 0-120. The lower scores stand for better emotional regulation.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  2. Changes of total scores of Adaptive Behavior Assessment System

    Adaptive Behavior Assessment System is a parents' report questionnaire for adaptive behavior. The scores ranges from 9-171. The higher scores stand for better adaptive behavior.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  3. Changes in accuracy of Frith-Happe animation

    A quick and objective test of Theory of Mind. 8 questions in total, the more correct questions stand for better Social Cognition.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  4. Changes in accuracy of Eyes task

    An advanced test for Theory of Mind. 43 questions in total, the more correct questions stand for better social skills.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  5. Changes in accuracy of Wisconsin Card Sorting Test

    An advanced test for cognitive flexibility. 128 questions in total, the more correct questions stand for better cognitive flexibility.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  6. Changes of total scores of Behavior Rating Inventory of Executive Function

    Behavior Rating Inventory of Executive Function is a parents' report questionnaire for executive function. The score ranges from 75-225. The lower scores stand for better executive function.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  7. Raven's Progressive Matrices

    An advanced test for for executive function. 60 questions in total, the more correct questions stand for better executive function.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  8. Autism Diagnostic Observation Schedule - Generic

    The Autism Diagnostic Observation Schedule is a semi-structured assessment of communication, social interaction, and play (or imaginative use of materials) for individuals suspected of having autism spectrum disorders. The social affect domain includes the social and communication items ranging from 0 to 20. The higher scores stand for more clinical severity of autism spectrum disorder.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  9. MRI T1

    Brain structural volumes (cm²)

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  10. functional MRI (resting-state/biological motion task) - BOLD signal

    Blood-oxygen-level-dependent (BOLD) signal is a measurement used in fMRI, which reflects the neural activity.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  11. Diffusion Tensor Imaging (DTI) - FA

    Fractional anisotropy (FA) is a measurement used in DTI, which reflects the movement of water molecules. FA ranges from 0 to 1, the higher FA value may represent more intact axons.

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

  12. Electroencephalography

    Resting state EEG (alpha power / frontal gamma power)

    Measured: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)

Questions about this trial

What is this clinical trial studying?

A study testing intermittent theta burst stimulation in people with Autism Spectrum Disorder, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

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 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 8 Jul 2022. 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 Taiwan. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hsing-Chang Ni (88633281200 ext. 3815, alanni0918@yahoo.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes of total scores of Social Responsiveness Scale (time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)). 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 NCT04987749, which also lists 1 linked publication.

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.
