Profiling Autism Symptomatology: An Exploration of the Q-ASC Parental Report Scale in Capturing Sex Differences in Autism.

Mae Simcoe et al. (2018) asked parents to fill out the new Q-ASC scale. The scale lists autism traits that parents notice at home.

The team looked for patterns in the answers. They wanted to see if girls and boys scored differently.

Eight clear groupings of items showed up again and again. Parents of girls often marked different items than parents of boys.

Age also changed the pattern. The scale picked up these girl-boy gaps better than older checklists.

Two earlier parent surveys seemed to clash. Sutherland et al. (2017) said parents see "almost no core sex gaps." Eussen et al. (2016) said carers notice "very different early red flags in girls." The Q-ASC solves the fight by giving parents finer items to rate.

Ros-Demarize et al. (2020) warned that common screeners miss girls because they lump all social items together. The Q-ASC keeps social pieces separate, so girls who mask still get flagged.

Rodriguez-Seijas et al. (2020) showed preschool girls have milder social affect. The Q-ASC now lets parents report that exact mild gap at home, closing the loop.

If you assess girls with autism, add the Q-ASC parent form to your kit. It gives you sex-specific item clusters you can trust. The scale may catch girls who score just under cutoff on older tools, saving months of wait time.
