Objective: The purpose of this study was to test the reliability of the Sensory Challenge Protocol (SCP), a laboratory procedural tool that has been used to discriminate differences in sensory processing between typically developing (TD) children and children with Autism Spectrum Disorder (ASD).

Method: Electrodermal activity (EDA) during rest and in response to

sensation was measured using skin conductance. Skin conductance

measures were used to calculate ICC (Intraclass Correlation Coefficient)

reliability in 14 children with ASD and 18 TD children.

Results: ICC reliability during rest phase (tonic) for both groups was good to moderate (.65 - .73). ICC reliability during response to sensation (phasic) was good to moderate for amplitude (.60 - .81) and magnitude (.50 - .75) of response measures. In addition, high to moderate reliability (.51 - .93) for Non-specific response (NSR) measures were found.

Conclusion: This study supports the SCP as a reliable tool to measure response to sensation in TD children and children with ASD.
