Resilience, the capacity to cope with stress and adversity, is universally regarded as a positive and valued trait (LeBuffe & Naglieri, 2012). The purpose of this study was to explore the potential for nature preschools to support the development of initiative, self-regulation, and attachment, which are key protective factors that can offset or moderate the effects of stress and adversity and allow a child to thrive or even by transformed by adversity. The Deveraux Early Childhood Assessment for Preschoolers, Second Edition (DECA-P2) was used in a pretest and posttest of a sample of 78 children who attended nature preschools, as well as in a baseline group of 14 children who attended a non-nature preschool. Results suggest a significant strengthening of these protective factors over the course of a school year in preschool participants who attended a nature preschool. Implications are discussed in the context of the study's limitations.
