RECRUITINGChanges 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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
Raven's Progressive Matrices
An advanced test for for executive function. 60 questions in total, the more correct questions stand for better executive function.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
MRI T1
Brain structural volumes (cm²)
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
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.
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
Electroencephalography
Resting state EEG (alpha power / frontal gamma power)
Time frame: baseline; post TBS (8 weeks after baseline); One month follow up (4 weeks after post TBS)
