Development of the concentric sphere family environment model and companion tools for culturally congruent family assessment.

The article presents development of a nursing model for holistically understanding the family environment that acts on family well-being as well as of tools based on this model to assess family well-being. These were constructed by using qualitative, quantitative, and literary approaches, such as the Delphi technique, a literature review, semistructured interviews with families, and ethnographic studies in Japan, Hong Kong, and the United States. In the "Concentric Sphere Family Environment Model," a three-dimensional logical space is formed by the three assessment axes of relationships (structural distance, functional distance, and temporal distance) and five systems (supra system, macro system, micro system, family internal environment system, and chrono system) located therein. The "Family Environment Assessment Index" comprises 37 items for assessing the family well-being, and for each of their specifications useful sample questions are provided to conduct the culturally congruent family assessment.
