Study Overview
The E-Risk Longitudinal Study aims to build knowledge about children's behavioral development and mental health, including disruptive behaviors such as oppositional conduct, hyperactive and inattentive behaviors, depression, and anxiety. It addresses: a) which specific environmental risk factors contribute to the early emergence of mental health problems; b) whether environmental risk factors interact with genetic risk to influence mental health problems; c) whether and how child-specific parenting experiences explain differences in behavioral outcomes between children in the same family; d) how the effects of risk are mediated through children's neuropsychological executive functions, social-information processing, and verbal skills. Data were collected at age 5, 7, 10, and 12 to investigate specific environmental risk factors that contribute to the early emergence of mental health problems. Data collected included: interview and observational data from parents (typically, mothers) and children; survey data from teachers; cognitive assessments; grades; and other key data.
