Understanding characteristics associated with burden in caregivers of children with autism spectrum disorder (ASD) is critical due to negative health consequences. We explored the association between child sensory subtype, sensory dimension scores, and caregiver burden. A national survey of caregivers of children with ASD aged 5-13 years was conducted (n = 367). The relationship between variables of interest and indicators of caregiver burden, including health-related quality of life (HRQOL) and caregiver strain, was examined with canonical correlation analyses. Caregiver strain was, but caregiver HRQOL was not, significantly associated with child sensory subtype and sensory dimension scores. Caregiver age, child age, and household income were also associated with caregiver strain. Potential explanatory mechanisms for these findings, derived from published qualitative studies, are discussed.
