What is being measured
The primary outcome is the main question the study is designed to answer.
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
Secondary outcomes (13)
Changes of total scores of Aberrant Behavior Checklist
ABC is a parents' report questionnaire for aberrant behavior. The lower scores stand for less aberrant behavior.
Measured: baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
Changes of total scores of Child Behavior Checklist
CBCL is a parents' report questionnaire for behavioral and emotional problems. The lower scores stand for better behavioral and emotional regulation.
Measured: baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
Changes of total scores of Adaptive Behavior Assessment System
Adaptive Behavior Assessment System is a parents' report questionnaire for adaptive behavior. The score ranges from 9-171. The higher scores stand for better adaptive behavior.
Measured: baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
Changes of total scores of Behavior Rating Inventory of Executive Function
An advanced test for cognitive flexibility. 128 questions in total, the more correct questions stand for better cognitive flexibility.
Measured: baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
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 (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)
MRI T1
Brain structural volumes (cm²)
Measured: baseline; post TBS (4 weeks after baseline)
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 (4 weeks after baseline)
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 (4 weeks after baseline)
Electroencephalography
Resting state EEG (alpha power / frontal gamma power)
Measured: baseline; post TBS (4 weeks after baseline)

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 2 inclusion and 18 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: under way, not looking for participants, as of the sponsor's last update on 4 Jun 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 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.

This study is still under way. Results are not available in the source record yet.
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?
Changes of total scores of Social Responsiveness Scale (time frame: baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)). 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?
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 4 Jun 2025.
