Real World Example of Children’s Global Assessment Scale

Sarah, a 10-year-old girl with autism, faced significant challenges both in school and at home. To help manage her difficulties, her parents collaborated with a mental health professional who employed the Children’s Global Assessment Scale to gauge Sarah’s overall functioning. Here’s how Sarah’s journey unfolded:

  • Before treatment: Initially, Sarah’s CGAS score was 45, which highlighted moderate problems in critical areas like school performance and social interactions with peers.
  • During treatment: As Sarah began receiving therapy and additional support at school, her situation improved noticeably. Her CGAS score increased to 65, indicating that while some issues persisted, her overall functionality had enhanced significantly.
  • After treatment: With sustained support and ongoing interventions, Sarah continued to make progress. Her Children’s Global Assessment Scale score eventually rose to 85, demonstrating good functionality across various life aspects.

By addressing her unique needs at school and continuing therapy, Sarah was able to overcome many challenges and improve her quality of life. Her progress serves as a hopeful example for others in similar situations.
