Predictors and course of daily living skills development in toddlers with autism spectrum disorders.

Laugeson et al. (2014) watched toddlers with autism for two years. They tracked daily living skills, IQ, and autism severity. They also asked parents how stressed they felt.

The team wanted to know which kids gain daily living skills fastest. They also asked if skill gains lower parent stress.

Younger age, higher IQ, and milder autism signs predicted faster daily living skill gains. When skills grew, parenting stress dropped.

Kids who started with lower IQ or more severe symptoms still improved, just at a slower pace.

Clarke et al. (2025) followed the same idea into adulthood. They show that for autistic adults with IQ under 70, childhood personal skills like tooth brushing predict life success. For adults with IQ over 70, community skills like ordering food matter more. Together, the papers say start early, then shift goals as IQ changes.

Hodge et al. (2021) studied preschoolers and also found higher IQ boosts adaptive skills. They added that richer families see even bigger gains. The toddler and preschool data line up: cognition drives daily living skills.

Kilincaslan et al. (2019) looked at older Turkish children with both autism and ID. They found these kids score lower on daily living skills than kids with ID alone. This seems opposite to the toddler study, but the kids were older and IQ-matched. The toddler paper shows growth is possible; the Turkish paper shows gaps widen if we wait.

Start daily living skills as soon as you get an autism diagnosis. Kids under three with lower IQ or more severe symptoms still make gains, and every gain cuts parent stress. Build personal care first, then move to community skills when IQ tops 70. Track progress monthly and celebrate small wins with families.
