Reliability of Electrodermal Activity: Quantifying Sensory Processing in Children With Autism.

Objective: We established test-retest reliability of electrodermal markers used to quantify physiological response to sensation using the Sensory Challenge Protocol in children with and without autism spectrum disorder (ASD).

Method: Electrodermal activity (EDA) was measured during rest and in response to sensory inputs. Fourteen children with ASD and 18 typically developing children were tested and retested after 2-6 wk on skin conductance response, skin conductance level, nonspecific skin conductance response, and habituation.
