Empathy is directly related to one’s satisfaction with a romantic partner, and therefore, most approaches to couples therapy explicitly address empathy as a means for creating positive relational change. Imago relationship therapy (IRT) is practiced extensively worldwide yet lacks research validating its effectiveness. Given IRT’s focus on developing empathy within the members of the romantic partnership, it is important to examine how empathy contributes to change in relationship satisfaction. This random and controlled study examined the impact of 12 weeks of IRT treatment on individual (N = 60) empathy levels. Results showed a significant interaction between time and condition and found significant increases in treatment group empathy levels at each of three assessment points. These findings begin to emphasize the impact of IRT on couple empathy levels and highlight the potential benefits of using this particular therapeutic modality to promote positive relational change within romantic relationships. The research would have benefited from greater diversity within the sample and a greater understanding of the specific therapist interventions that impact client couple empathy levels.
