ABSTRACT
Infidelity is a serious relationship betrayal that can bring significant negative consequences, including the end of the relationship. Yet many couples seek professional help for reconciliation and healing. Given the severe individual and relational distress accompanying infidelity, it is one of the most difficult problems to treat in couples therapy. In this chapter, the authors present an integrative framework for treating infidelity based on the Intersystem Approach, a metatheory that integrates theory and techniques from both individual and relational therapy. The Intersystem Approach to treating infidelity is grounded in a systemic perspective and addresses four interconnected domains: individual factors, couple relational factors, intergenerational factors, and sociocultural factors. Treatment includes five flexible and interrelated phases: (a) managing the initial crisis; (b) assessment of individual, systemic, intergenerational, and contextual factors; (c) identifying unifying factors, rebuilding trust, and facilitating forgiveness; (d) identifying and treating factors that contributed to the infidelity; and (e) revitalizing the relationship and promoting intimacy through communication. Identifying and enhancing unifying factors is particularly important to facilitate healing, unite couples, and decrease vulnerability to future betrayals. Therapists apply the treatment in a flexible manner in order to meet the unique needs of each couple.
