Is bullying associated with emerging school refusal in autistic boys?

The experience of being bullied is widespread among autistic youth. Relatively little empirical work has been done on the relationship between the bullying of these youth and school refusal (SR). This study of 67 school-age autistic boys (M = 11.7 years, SD = 2.3 years) examined several factors that may contribute to SR. Data regarding boys' age, generalised anxiety disorder (GAD), major depressive disorder (MDD), key ASD diagnostic criteria, and frequency of being bullied were collected. Results indicated that, while boys displaying emerging SR also had significantly higher GAD and MDD than boys without emerging SR, only the frequency of being bullied made a significant contribution to emerging SR. Implications for prevention and treatment of SR among autistic youth are discussed.Pathways through Adolescenc

Diurnal variation in peripheral (hair) vs central (saliva) HPA axis cortisol concentrations

Cortisol concentrations in hair and saliva collected from male and female adults over a 15-hour period were compared for differences in overall level and cyclic pattern. Typical diurnal fluctuations were noted for both salivary and hair cortisol, with some individual differences that are congruent with the previous literature. Issues of the link between central and peripheral HPA axes are raised for discussion and further investigation, and hypothetical explanations for the diurnal variability shown in these two sets of cortisol secretion patterns are discussed from an evolutionary advantage perspective

An investigation of hair cortisol concentration across body sites and within hair shaft

Cortisol concentrations in hair collected from young male and female adults were assayed and compared for differences along shaft length and between body sites. No significant differences were found between hair shaft sites, supporting a model of the hair shaft as 'alive' and responsive to environmental demand in terms of cortisol production. Hair taken from forearms had significantly higher concentrations of cortisol than hair from lower legs, suggesting a localized hair cortisol response and verifying previous findings. Issues of the link between central and peripheral HPA axes are raised for discussion and further investigation
