It's very good and useful. There are more tools in the Roadmap. Also, the Roadmap advises cross-sector collaboration a bit more than the UK version, in that no one organization "owns" the process. The entire community does.
And, what we've observed is very important, is that people who understand the "unified science" of human development are more successful in implementing trauma-informed and resilience-building practices, and institutionalizing them in organizations.
The "unified science" includes the epidemiology of ACEs (ACE Study and the dozens of ACE surveys that have followed, including on that England did); the neurobiology of toxic stress; the long-term biomedical and epigenetic consequences of toxic stress; and resilience research.
For example, you can give parents all sorts of advice and training in how to be healthier parents, and it falls apart the moment they're triggered when, for example, their two-year-old hits them and they, automatically responding to having been hit in their own childhood, hit their child. (A trigger is the amygdala's response that activates before the prefrontal cortex can decide if the action is useful or not.) The parents then feel guilty that they're not able to comply with being a "good" parent.
But if they learn about ACEs and why they respond the way they do, they have a clearer idea about how to learn how to self-regulate, and why it's important. In parenting classes that integrate ACEs, the parents are much more engaged in learning how to do healthy parenting, and have been shown to be more empathetic toward their children because they understand their kids' behavior is not intentional to anger them.
