Emotionally Focused Therapy (EFT) is an approach for working with couples that focuses on the negative interaction cycles perpetuated by deep-seated emotional vulnerabilities. This therapy attempts to alleviate distress by intervening on an emotional level in order to promote more caring interactions that can enhance relationships. Proponents state that this is one of the most effective forms of couples' therapy. In this review, EFT is described and the empirical literature on EFT is evaluated as to whether it supports this claim. The review did support the notion that EFT is a valid and effective form of marital therapy, and also strongly supported the efficacy of this treatment to promote positive change in distressed couples.
