Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos
Age-Related Differences In The Association Between Stereotypic Behaviour And Salivary Cortisol In Young Males With An Autism Spectrum Disorder, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos
Vicki Bitsika
To identify if age influenced the relationship between one of the central symptoms of Autism Spectrum Disorder (ASD) and physiological stress, the association between stereotypic behaviour (SB) and stress-related cortisol concentrations was examined in a sample of 150 young males with an ASD. Parent-rated SB was significantly correlated with cortisol concentrations for boys aged 6 years to 12 years but not for adolescents aged 13 years to 18 years. This age-related difference in this association was not a function of cortisol concentrations but was related to differences in SB across these two age groups. IQ did not have a significant …
Eight-Month Test-Retest Agreement In Morning Salivary Cortisol, Self- And Parent-Rated Anxiety In Boys With An Autism Spectrum Disorder, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Nicholas Andronicos
Eight-Month Test-Retest Agreement In Morning Salivary Cortisol, Self- And Parent-Rated Anxiety In Boys With An Autism Spectrum Disorder, Christopher Sharpley, Vicki Bitsika, Linda Agnew, Nicholas Andronicos

The agreement over time in morning salivary cortisol concentrations and also self- and parent-rated anxiety was investigated in a sample of 16 boys with an ASD. Cortisol and anxiety data were collected eight months apart. Results indicated that there were significant correlations between each pair of measures from the two occasions, suggesting that cortisol concentrations and anxiety did not vary much at all over that time, challenging the assumption that cortisol needs to be measured over multiple days to obtain reliable data from children with an ASD. Implications for research into the ways these children respond to chronic stressors are …
