This book is a companion to Behavioral, Humanistic-Existential, and Psychodynamic Approaches to Couples Counseling (Reiter & Chenail, 2017) and focuses on the constructivist, critical, and integrative approaches to working with couples. Regardless of approach, couples counselors need to understand the various dynamics of couples, such as formation, history, and diversity (see Reiter, 2017). These dynamics filter into the case conceptualization, to provide a more encompassing view of the couple, why they are currently having difficulties, and potential pathways toward change.
