The 3-5-7 Model® was first developed by Darla Henry as a compilation of her extensive work and experience in child welfare. The tasks of the model (clarification, integration, and actualization) were first described by Darla’s colleague Kay Donley-Zeigler. Darla’s doctoral research on resiliency in children in 1999 was the basis for the development of the five questions of the model. The seven skills have been identified as an important set of strategies that workers can use to promote the work of grieving losses and rebuilding relationships.
