Traumatic events are associated with actual or threatened risk to life, serious injury or sexual violence. The prevalence of traumatic events is particularly high among people with intellectual disability. Trauma-informed care is an important yet unresearched area in intellectual disability services. This article outlines the principles of trauma-informed care and considers how these can be applied in practice to people with an intellectual disability. The authors discuss the limited literature on the implementation of trauma-informed care in intellectual disability services, which is primarily drawn from case studies or non-empirical research. The article includes two examples of trauma-informed care implemented in intellectual disability settings and outlines areas for future research.
