Abstract: The current study proposed an expansion model of Emotionally Focused Therapy (EFT). This model explored forgiveness as key therapeutic process in EFT and suggested it be integrated into Step 5, the most intrapsychic in EFT. The expansion model weighed the benefits of intrapsychic forgiveness over interpersonal forgiveness in EFT. It discussed possible threats to the integrity of the therapeutic alliance resulting from interpersonal forgiveness and how the alliance might be protected. It was suggested that interpersonal forgiveness in EFT might give rise to a dyadic power struggle, the occupation of a moral high ground by a wounded individual, and the possibility of re-injury by a partner who conforms to the Principle of Least Interest. The expansion model examined the specificity of language in EFT, in particular reference to the words forgiveness, reconciliation, and trust. Vocabulary and labeling in EFT were discussed, and it was proposed that words like offender, offended, victim, and transgressor be banished from the EFT lexicon, as the careless use of vocabulary by therapists might impair the forgiveness process in EFT. Forgiveness is one way of unhooking from attachment injuries, and as part of the forgiveness process in EFT, this expansion model proposed an amplification of family-of-origin issues in EFT. A definition of forgiveness was suggested, which included an unconditional letting go, an absence of labeling individuals, and that while forgiveness may not be contingent upon emotional readiness, it plays an integral role somewhere in the process. Two case examples and three disquisitions were included. In the expansion model, it was suggested that in the context of forgiveness in EFT, a continuum of trust be established. The limitations of the extension model were discussed, as were suggestions for future research.
