This article critically reviews the foundational studies carried out by Felitti in the US and Bellis in the UK and their colleagues examining the relationship between Adverse Childhood Experiences (ACEs) and adult health and morbidity. These studies have paved the way for much research on childhood adversity and its impact on child development and brain functioning at a family level. ACEs have gained traction in the UK in terms of policy targeting dysfunctional families through early intervention to stop the intergenerational effects of adverse childhood experiences. This article questions the foundational research that argues for family-level, parent-based intervention, especially in light of substantial evidence about the biological embedding of poverty and the direct links between disadvantage and child development. It also hopes to raise awareness about the contested nature of ACEs and their growing influence on family policy.

Childhood sexual abuse (CSA) and physical abuse (CPA) are well-established risk-factors for a wide of range of proximal and distal outcomes. The lack of availability of an optimal design for examining abuse and its consequences has resulted in the use of various approaches, each having its own limitations. We describe the Childhood Trauma Study, which ascertained families from a large young adult Australian twin cohort on the basis of twins' responses to screening questions assessing CSA and CPA. We report data from 3407 participants including twins, non-twin siblings, and their parents. Our data demonstrate the feasibility of using a comprehensive assessment to evaluate retrospective history of childhood abuse in an adult sample. We observed that risk for each form of abuse increased incrementally with the number of parents with alcohol problems. Psychometric properties of our measures of CSA and CPA including reasonable long-term stability, construct validity, and evidence of familial corroboration compare favorably with those of other reports in which samples were considerably younger and assessments were repeated over shorter intervals.
