Our purpose is to introduce a novel technique for evoking emotions associated with moments of closeness with another person (relational savoring), to describe its theoretical grounding, specifics of treatment targets and outcomes, as well as to provide the preliminary evidence for its efficacy in promoting flourishing. We rely on attachment theory, the broaden-and-build theory of positive emotions, and emotion-focused therapy as foundations for our understanding of how secure relationships are built and maintained and for proposing how relational savoring can promote flourishing through strengthening relationships. To illustrate specific mechanisms of change, we provide examples from a recently completed study of mothers of young children. Finally, we discuss how the technique can be integrated into clinical practice as well as how it might be used to augment other forms of therapy.
