EFT has been extensively researched over the last 25 years with outstanding outcomes.
A substantial body of research supporting the effectiveness of EFT for couples now exists. To date, the research on EFT has been conducted with couples; mostly cis-gender and monogamous, but research is beginning to explore the effectiveness of EFT across a broader range of relationships, including queer couples, throuples and polyamorous relationships. Research studies find that 70-75% of relationships move from distress to recovery and approximately 90% show significant improvements in relationship satisfaction.
EFT can assist by improving attachment security in many different kinds of relationships; couples and relationships of other configurations as well as families, friendships and work relationships.
