Resilience as an attribute of the developmental system: comments on the papers of Professors Masten & Wachs.

When conceptualized within a developmental systems theoretical framework, resilience involves mutually beneficial, reciprocally influential relations between a person and his or her context. The key features of developmental systems theory, which stress the plasticity of these relations, lead to an optimistic view of the possibility of promoting positive human development (PHD) across the life span. The results of recent longitudinal research about adolescent development allow this period to serve as a sample case of how positive development is associated with the alignment of the strengths of individuals with ecological resources for healthy growth.
