A growing body of research suggesting a negative association between basal levels of cortisol and persistent antisocial behavior has emerged. The present study examined relations between awakening cortisol levels and antisocial trajectories from ages 5 to 15 years among individuals in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Antisocial behavior was defined by semiparametric group modeling techniques, which revealed antisocial patterns parallel to Moffitt's (1993) taxonomy of antisocial trajectories.

The Mental Health Surveillance Study (MHSS) is an ongoing initiative by the Substance Abuse and Mental Health Services Administration to develop and implement methods for measuring the prevalence of serious mental illness (SMI) among adults in the USA. The 2008 MHSS used data from clinical interviews administered to a sub-sample of respondents to calibrate mental health screening scale data from the National Survey on Drug Use and Health (NSDUH) for estimating the prevalence of SMI in the full NSDUH sample. The mental health scales included the K6 screening scale of psychological distress (administered to all respondents) along with two measures of functional impairment (each administered to a random half-sample of respondents): the World Health Organization Disability Assessment Schedule (WHODAS) and the Sheehan Disability Scale (SDS).

This study examined early observed parenting and child-care experiences in relation to functioning of the hypothalamic-pituitary-adrenocortical axis over the long term. Consistent with the attenuation hypothesis, individuals (n = 863) who experienced: (a) higher levels of maternal insensitivity and (b) more time in child-care centers in the first 3 years of life had lower awakening cortisol levels at age 15. Associations were small in magnitude.
