Examining Trajectories of Daily Living Skills over the Preschool Years for Children with Autism Spectrum Disorder.
Daily living skills in preschoolers with ASD do improve over time, but kids with lower ASD symptom severity improve faster.
01Research in Context
What this study did
Leezenbaum et al. (2019) followed preschoolers with autism for several years. They tracked daily living skills every few months with the Vineland Adaptive Behavior Scales.
The team wanted to see if these skills grew over time and whether initial autism severity changed the speed of that growth.
What they found
Daily living skills scores went up year after year. Kids who started with milder autism symptoms improved faster. Children with more severe symptoms still gained skills, just at a slower pace.
How this fits with other research
Matson et al. (2013) saw the same link in a single-time snapshot: preschoolers with an autism label scored lower on practical daily skills than kids without the label.
Dellapiazza et al. (2024) later showed that autism symptoms themselves can shift well past preschool. Together these studies tell a two-part story: daily living skills keep climbing, but social-communication symptoms may still move up or down.
Golos et al. (2022) compared participation levels and found ASD preschoolers joined structured self-care tasks often, yet still lagged behind typical peers. B et al. now show that, given time, those same tasks can improve if we keep teaching them.
Why it matters
You can reassure families that dressing, toileting, and brushing teeth usually get better between ages 3 and 6. Start goals earlier for children with higher baseline severity; they need more repetitions to reach the same endpoint. Track Vineland raw or growth-scale scores each quarter so small gains are visible even when standard scores creep up slowly.

03Original abstract
Preschool children with autism spectrum disorder (ASD) experience slower development of daily living skills (DLS) that are essential for independent functioning compared to typically developing children. Few studies have examined the trajectories of DLS in preschoolers with ASD and the existing literature has reported conflicting results. This study examined DLS trajectories and potential covariates for preschoolers with ASD from a multi-site longitudinal study following children from diagnosis to the end of grade 1. Multi-level modeling was conducted with DLS domain scores from the Vineland Adaptive Behavior Scales-2. The results demonstrated a positive trajectory of increasing scores over time, associations of age of diagnosis, developmental level, stereotypy, and language skills with the mean score at T4 or age 6 years, whereas rate of change was only associated with ASD symptom severity, such that an improvement in DLS trajectory was associated with lower and improving ASD symptom severity.
