I grew up a military brat, so I'm always interested in research that discusses the impact on children from frequent mobility or "rootlessness". Most of it tends to be quite positive. I also conducted a number of studies in school that revealed strong resilience factors in children of mobile families. These results echoed research conducted back in 1972 by Phillip Mann that showed college students from mobile families actually displayed more cognitive complexity, flexibility, autonomy AND less anxiety. So, for all of you parents out there that are worried that a move might disrupt your children's lives and scar them forever, please consider the benefits. They just might thrive and discover internal adaptive strengths (resilience) they might not otherwise have developed.
