Tipping the Scales: The Predictive Utility of the PCE–ACE Ratio
This study examined how the balance between adverse childhood experiences (ACEs) and positive childhood experiences (PCEs) is associated with adult outcomes in Northern Ireland.
Using data from a representative sample of 1,203 adults, the research found that a higher PCE:ACE ratio was linked to better outcomes across a range of areas, including lower likelihood of arrest, incarceration, school exclusion, substance use and mental health diagnosis. Those with lower ratios experienced the highest levels of adversity.
The findings suggest that ratio-based approaches may offer a useful population-level way of understanding risk and protection, with important implications for prevention and early intervention.
Childhood Adversity, Community Violence and Adult Outcomes in Northern Ireland
This research explored the prevalence and impact of both adverse childhood experiences (ACEs) and extrafamilial violence (EFV) in Northern Ireland.
Drawing on a representative adult sample, the study found that while ACEs remain strongly associated with poorer outcomes in adulthood, experiences of violence beyond the family also make an important independent contribution. EFV was linked to poorer mental health outcomes, including post-traumatic stress and anxiety, even after adjusting for age, gender and deprivation.
The study highlights the need to look beyond household adversity alone when understanding long-term harm and planning prevention strategies.
How Ready Are Organisations to Recognise, Respond to and Reduce Child Criminal Exploitation?
Commissioned by the Safeguarding Board for Northern Ireland, this review examined how prepared public bodies are to respond to child criminal exploitation (CCE).
Using an implementation framework, the review found a mixed picture. While awareness of CCE has increased, important challenges remain around information sharing, data systems, confidence in responding, and the consistency of training and support available to professionals.
The review recommends stronger multi-agency data-sharing protocols, clearer operational processes, and more consistent training and supervision to improve responses to children at risk.
