The effects of disability status and perceived neighbourhood cohesion and safety on adverse childhood experiences among college students.

Adverse childhood experiences (ACEs) are early traumatic events that can have adverse long-term developmental effects on a person's health and well-being. Individuals with disabilities are at a greater risk of all types of ACEs. However, the impact of having a disability and neighbourhood context on ACEs is under-researched, and even less is known about whether neighbourhood cohesion and safety affect the relationship between disability status and ACEs. The purpose of this study is to examine the direct and indirect pathways between disability status, childhood neighbourhood environment and ACEs. The final study sample of this study was 2,049 college students, consisting of 494 students with disabilities and 1,555 students without disabilities from six universities in the U.S. and Canada between March 2016 and June 2017. Data analysis included Pearson correlations and structural equation modelling procedures using Stata 16 software to test a partial mediation model. Having a disability has both a direct effect and an indirect effect through the neighbourhood environment on ACEs after controlling for socio-demographic characteristics associated with neighbourhood environment or ACEs. The findings suggest that neighbourhood cohesion and safety can be a mediator between disability status and ACEs, and the potential cumulative risk and protective factors that can contribute to ACEs. To elucidate the relationship between disability status and a higher risk for ACEs fully and prevent ACEs that can negatively impact the long-term health outcomes, greater attention to environmental risk and protective factors is urgently needed.
