Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes of total scores of Social Responsiveness Scale | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | Social Responsiveness Scale can measure the autism clinical severity with the range from 65-260. The lower scores stand for better social responsiveness. |
| Changes of total scores of Repetitive Behavior Scale-Revised | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes of total scores of Emotional Dysregulation Inventory | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | 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. |
| Changes of total scores of Adaptive Behavior Assessment System | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | 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. |
| Changes in accuracy of Frith-Happe animation | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | A quick and objective test of Theory of Mind. 8 questions in total, the more correct questions stand for better Social Cognition. |
| Changes in accuracy of Eyes task | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | An advanced test for Theory of Mind. 43 questions in total, the more correct questions stand for better social skills. |
| Changes in accuracy of Wisconsin Card Sorting Test | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | An advanced test for cognitive flexibility. 128 questions in total, the more correct questions stand for better cognitive flexibility. |
| Changes of total scores of Child Behavior Checklist | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | CBCL is a parents' report questionnaire for behavioral and emotional problems. The lower scores stand for better behavioral and emotional regulation. |
| Raven's Progressive Matrices | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | An advanced test for for executive function. 60 questions in total, the more correct questions stand for better executive function. |
| MRI T1 | baseline; post TBS (4 weeks after baseline) | Brain structural volumes (cm²) |
| functional MRI (resting-state/biological motion task) - BOLD signal | baseline; post TBS (4 weeks after baseline) | Blood-oxygen-level-dependent (BOLD) signal is a measurement used in fMRI, which reflects the neural activity. |
| Diffusion Tensor Imaging (DTI) - FA | baseline; post TBS (4 weeks after baseline) | 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. |
| Electroencephalography | baseline; post TBS (4 weeks after baseline) | Resting state EEG (alpha power / frontal gamma power) |
| Changes of total scores of Behavior Rating Inventory of Executive Function | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | An advanced test for cognitive flexibility. 128 questions in total, the more correct questions stand for better cognitive flexibility. |
| Changes of total scores of Aberrant Behavior Checklist | baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline) | ABC is a parents' report questionnaire for aberrant behavior. The lower scores stand for less aberrant behavior. |
