Outcome Measures

Primary Outcomes (2)

  • 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 (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.

    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

    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

    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

    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

    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

    baseline; post TBS (4 weeks after baseline); One month follow up (8 weeks after baseline); Two months follow up (12 weeks after baseline)

  • +8 more secondary outcomes
