Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Primary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Primary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	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 86-258. The lower scores stand for better executive function.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	Raven's Progressive Matrices	An advanced test for for executive function. 60 questions in total, the more correct questions stand for better executive function.	baseline; post TBS (4 weeks after baseline); One month follow up (4 weeks after post TBS); Two months follow up (8 weeks after post TBS)
Secondary	MRI T1	Brain structural volumes (cm²)	baseline; post TBS (4 weeks after baseline)
Secondary	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.	baseline; post TBS (4 weeks after baseline)
Secondary	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.	baseline; post TBS (4 weeks after baseline)
Secondary	Electroencephalography	Resting state EEG (alpha power / frontal gamma power)	baseline; post TBS (4 weeks after baseline)
