These can manifest as physical health issues, mental health challenges, behavioral patterns or social challenges. ![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXfKPi-CdcmYiJrCLF5SDLGcaZAOEV_jiXbhK5AYYfN4UsalqHQFnMeDiH0ymfYJlGV0LVDNy94P_fyUBlQ1YLBwW_vkZpoo6mDgN2bW4D7kwyJJoswYOHTZnpcG0JXzQTSPbLjhoPywVsvzb9mwB_I?key=d86n1pHjOs0Oq0USwvByelTd) *Source:* [*CDC*](https://www.cdc.gov/aces/communication-resources/index.html) ACEs are typically not isolated events. Rather, they often occur in clusters, creating layers of trauma that can have lasting, complex effects into adulthood. There is also a generational risk for the children of parents who have themselves experienced ACEs. Because of these possible long-term impacts, it is important to have an accurate, effective ACEs screening tool.    Assessing ACEs “Unfortunately, the initial Adverse Childhood Experiences Scale (ACES) is a rather crude scale with multipart questions and no indication of whether a given event reoccurred,” says Dr. Norman Hoffmann, clinical psychologist and expert in clinical assessment of mental health and substance use disorders. “To remedy some of the problems \[with ACES\], I developed a revision dubbed the [ACES-R4](https://evincediagnostics.com/assets/images/ACES-R4-web.pdf). The ‘R’ refers to dividing the multipart items into independent questions. An item about a family member being arrested was added as a more prevalent issue than one going to prison. The ‘4’ refers to replacing the yes/no reporting option with a four-option Likert scale to document reoccurrence.”  Hoffmann adds that, “Initial research indicates that the individual questions provide a more precise association with conditions such as PTSD and major depressive episodes. For clinicians, the ACES-R4 provides a clearer indication of specific events that might underlie identified conditions.” By understanding ACEs, using an effective assessment tool and adopting a [trauma-sensitive approach](https://blog.changecompanies.net/trauma-informed-practices-for-group-facilitation), you can empower clients to explore their past, build resilience and move toward healing.
