The predictive relationship between sensory reactivity and depressive symptoms in young autistic children with few to no words
Depression, much like other mental health conditions, is common in autism, with autistic individuals much more likely to be diagnosed than their non-autistic peers. Sensory reactivity differences are also commonly experienced by autistic individuals and have been associated with depressive symptoms. However, there is little understanding of the predictive relationship between sensory reactivity and depressive symptoms, or the nature of this relationship in autistic children who speak few to no words. This study set out to explore the longitudinal relationship between sensory reactivity and depressive symptoms in 33 young autistic children who speak few to no words over two timepoints. We found positive correlations between depressive symptoms and hyper-reactivity and sensory seeking at both timepoints. We further found a bidirectional predictive relationship between depressive symptoms and sensory seeking. These results implicate sensory seeking in the development of depressive symptoms in young autistic children who use few to no words. Our findings have important implications for preventative mental health interventions, especially for those with a developmental language delay.Key words: autism; sensory reactivity; depression; children; language delay
