“…A large and varied empirical literature addresses the etiology of problem behaviors and the factors thought to contribute to resilience in at-risk populations from an ecological perspective. For example, it is commonly believed that in Western countries populated by peoples of European descent, where the bulk of these studies have been conducted, the greatest risks to the health of high-risk youth originate from delinquent behaviors such as drug and alcohol abuse, dangerous driving, and self-injurious behaviors (suicide, high-risk sexual activity) or social factors that include intrafamilial and extrafamilial violence, school failure, poor parenting, divorce or separation, and threats to family economic stability (Jaffe & Baker, 1999;Johnson, 1993;King, Boyce, & King, 1999;Lane & Murakami, 1987;Madigan, 2000;Prilleltensky & Nelson, 2000;Robinson, 1994;Vanier Institute of the Family, 2000). Though this list is comprehensive, leaders in the field of risk and resilience research acknowledge their inability to narrow down the causal or "keystone" (Fraser & Galinsky, 1997) factors that predict unhealthy and healthy outcomes among at-risk individuals or those factors that protect and divert children and youth from these problem behaviors (Kaplan, 1999;Loeber & Farrington, 2000;Masten, 2001).…”
