Sorry to inform you that on this page

Autism Spectrum Disorder Symptoms | Psych Central

you have the DSM 5 criteria for Autism spectrum disorder wrong.

What you have published is not from any DSM publication, it is the first published draft for DSM 5. The final product, published in DSM 5 differs on many items.

I hope you will replace this non-standard item with the real thing.

Thank you.
