Actually, what we see is that the children who tend to show more of those patterns of coping successfully have internal strengths—sometimes it's just the genetic lottery, if you will—but more often it's about patterns of extended family, opportunities in their communities to use their talents, recreational spaces, access to a cellphone and technology so that they can remain connected to their extended peer group, language skills, and an education system that adapts. There are a lot of factors that you can actually put in place that are well researched and that actually create the optimal conditions for children to survive well.
Of course, as your questions indicate, there are also children whose past risk exposure is so severe or so unique, or they have a constellation of risk problems, that you do need to tailor an intervention specifically for them. This is not related to refugee children, but if you look, for instance, at the Kids Help Phone, which is a national effort, you will see that it's actually overused or used disproportionately by children in rural communities and by indigenous children, largely because it's a protective factor that is very adaptable to people living in more marginalized communities and rural communities. I think that's where we get thinking about protective factors as really tailored to the risks that a child experiences, while not forgetting that most children respond really well simply to all the good things that we tend to give kids through communities that care about the newcomers who arrive.
