Therapists can benefit from a more nuanced understanding of underlying processes associated with romantic partners forgiving one another. Greater understanding of the processes linked with forgiveness has the potential to improve therapists' facilitation of forgiveness between partners. Departing from the status quo, the purpose of this investigation was to explore benign attributions and empathy as mechanisms linking attachment with forgiveness. After conducting a longitudinal structural equation model with a sample of young adults in romantic relationships (N = 171), the results showed that benign attributions mediated the association between anxious attachment and forgiveness, and empathy mediated the association between avoidant attachment and forgiveness. Clinically, targeting working models of attachment that underlie benign attributions and empathy may facilitate forgiveness.
