The sample (n = 102) consisted of participants at a weekend workshop taught by Gary Craig, the originator of EFT. Rowe found significant improvements in psychological symptoms from pre- to post-workshop assessments, with significant participant gains maintained on follow-up. The current study examined whether the improvements were attributable to Gary Craig alone or whether similar effects are noted when EFT is delivered by others. This study examined samples of participants at 4 different conferences, in which EFT was taught by others (n = 102).
In all 4 conferences, there were significant improvements in the severity and breadth of symptoms pre- and post-workshop (p < 0.001), and following 3 of the 4 conferences there were significant long- term gains (p < 0.001). The results indicate that EFT may be effective at reducing psychological symptoms when delivered by individuals other than the method’s founder and that EFT may reliably improve long-term mental health when delivered in brief group treatments.
