Clinical Profile of Autism Spectrum Disorder in a Pediatric Population from Northern Mexico.

González-Cortés et al. (2019) looked at kids with autism in northern Mexico. They wrote down each child's sex, IQ, and DSM-5 level.

The team wanted to see which problems show up most at each level of autism.

Most kids were boys. Lower IQ went with higher autism level.

Level 3 kids stood out for social-communication problems. Repetitive behaviors looked the same across levels.

Vanegas (2021) also used level to predict diagnosis timing. They found talking kids get diagnosed later, but immigrant families in bilingual homes get help sooner. Tania’s paper adds that in Mexico, level is tied more to social skills than to talk.

Kamp-Becker et al. (2009) split symptoms into two factors: social-communication and anxious-compulsive. Their split matches Tania’s finding that social issues, not repetitive acts, mark severe autism.

Schaaf et al. (2015) showed higher level raises self-injury risk. Tania’s data hint that the same social-communication gap seen in Level 3 could be the pathway to that risk.

When you assess a Spanish-speaking child, probe social routines first. If the child scores Level 3, write goals that boost joint attention and turn-taking before you target stereotypy. Share this focus with parents so they see why conversation practice comes first.
