ASD Traits Checklist
So, I’ve been researching ASD for nearly two and a half years for self-diagnosis purposes, and I’ve decided to make a checklist for ASD traits. I included as much as I could find from several different sources, including “atypical” and lesser-known traits.
These are traits, not symptoms, but they are associated with autism when enough of them are present. If you find that you display a lot of these traits, it’s likely that you are on the autism spectrum. I grouped them into categories for easier reading.
I hope this helps people who are suspecting they are on the autism spectrum or are in the journey of self-diagnosis.
