Background: Heart failure (HF) dyadic self-care science is advancing rapidly, as evidenced by recent theoretical work, literature reviews, and multiple empiric studies. Typologies, once considered archaic, are now viewed as person-oriented classification systems that allow a whole-system view of information patterns. This whole-system view is particularly needed to understand complex tasks like dyadic HF self-care. Purpose: The purpose of this article is to review the initial conceptualization of an HF care dyadic typology and the present advances in our thinking and suggest future directions for this clinically relevant classification system.
