A program for person-centered intervention—Pathways to Empowerment (PTE)—is indebted to the social quality approach (SQA), which has been developed as its scientific foundation. It provides comprehensive insight into all sorts of factors that have an impact on the quality of the daily lives of persons who have lost control in their lives. In this article, we describe what puzzles were encountered in this developmental process, specifically with regard to the constitutional factors of social quality, which are strongly linked to biographical development and personal agency and thus are the focal points of person-centered care. This part of the SQA seems less developed and researched. We describe how we have further developed the conceptualization of the constitutional factors and their dialectical relationships with the conditional factors into a practical structure for PTE. We make a case for the further development of the constitutional factors of the theory, specifically the concept of personal agency. A plea is made for reviewing the definition of social quality.
