The present study explores initial levels and trajectories of sensory features in ASD as well as, for comparison, typical development. Method Growth mixture modelling was used to explore classes of autistic and typically-developing participants based on caregiver-reported total sensory behaviours on the Short Sensory Profile (SSP) at two time points, when children were aged 2-5 and 4-10 years of age, respectively. Results Three classes are described: a mixed class of autistic and typically-developing participants with few problematic sensory behaviours (“Stable Mild”), a mostly-autistic class with more problematic sensory features (“Stable Intense”), and a small class of autistic participants whose sensory features reportedly worsened (“Increasingly Intense”). Autistic participants in the Stable Intense class exhibited high anxiety, while autistic participants in the Increasingly Intense class appeared to obtain high scores on cognitive assessments. Conclusions The heterogeneity of sensory features and challenges found in the present study may suggest that practitioners should conduct individualized assessments of sensory features in ASD. Furthermore, practitioners should be aware of links between sensory features and anxiety in ASD, which may imply that sensory accommodations and supports could protect against anxiety. Finally, the worsening of sensory features over time in the Increasingly Intense subgroup may indicate a need for continued monitoring of changes in sensory features, perhaps especially as sensory environments change during periods of transition.
