Sensory sensitivities are common in autism spectrum disorder (ASD) and impact daily life, but research has largely focused on children, neglecting older individuals. Likewise, while there is research regarding parental concerns for their autistic children's transition to adulthood, little is known about the role of sensory sensitivities. To address this gap, 66 parents of autistic adolescents and young adults were interviewed and their responses were qualitatively analyzed. All parents believed their children's sensory sensitivities impacted their transition to adulthood, primary developmentally/psychologically, interpersonally/socially, and managerially. These beliefs did not significantly differ by child characteristics, such as age and ASD severity. Parent perceptions were modality and context specific. Given these findings, transition planning should consider individual's specific sensory sensitivities to optimize independence.
