Interpersonal forgiving was conceptualized in the context of a 2-factor motivational system that governs people's responses to interpersonal offenses. Four studies were conducted to examine the extent to which forgiving could be predicted with relationship-level variables such as satisfaction, commitment, and closeness; offense-level variables such as apology and impact of the offense; and social-cognitive variables such as offunder-focused empathy and rumination about the offense. Also described is the development of the transgression-related interpersonal motivations inventory--a self-report measure designed to assess the 2-component motivational system (Avoidance and Revenge) posited to underlie forgiving. The measure demonstrated a variety of desirable psychometric properties, commending its use for future research. As predicted, empathy, apology, rumination, and several indexes of relationship closeness were associated with self-reported forgiving.The concept of forgiving, although not a traditional focus of personality and social psychology, has been of passing theoretical and empirical interest to the discipline for 40 years. In a chapter on benefit and harm in The Psychology oflnterpersonal Relations, Heider (1958) outlined a variety of attributional principles that underlie the quest for revenge after one has incurred an interpersonal transgression. In this context, Heider described forgiving as the forgoing of vengeful behavior, which he posited to be an implicit expression of the victim's self-worth. However,
