This chapter defines and describes different types of relationship infidelities and discusses existing research on understanding and treating infidelity. Studies examining the etiology, maintenance, and impact of infidelity in a relationship are reviewed and considered. The chapter then describes and critiques current empirically supported therapeutic approaches for treating infidelity, including a forgiveness-based intervention, traditional behavioral couple therapy, integrative behavioral couple therapy, and emotionally focused couple therapy. Important clinical considerations regarding cultural factors in conceptualizing and treating infidelity are addressed throughout the chapter and newer types of relationships and affairs (e.g., cyber affairs) also are discussed.
