EFT Universe supports the evidence-based standards defined by the American Psychological Association (APA) Division 12 (Clinical Psychology) Task Force ("APA standards" for short). These define an "empirically validated treatment" as one for which there are two different controlled trials conducted by independent research teams.

For a treatment to be designated as "efficacious," the studies must demonstrate that the treatment is better than a wait list, placebo, or established efficacious treatment. To be designated as "probably efficacious," a treatment must have been shown to be better than a wait list in two studies that meet these criteria or are conducted by the same research team rather than two independent teams. 

The APA standards advocate that studies contain sufficient subjects to achieve a level of statistical significance of p < .05 or greater, which means that there is only one possibility in 20 that the results are due to chance. The status of EFT as an evidence-based practice is summarized in this statement published in the APA journal Review of General Psychology: 
 

"A literature search identified 51 peer-reviewed papers that report or investigate clinical outcomes following the tapping of acupuncture points to address psychological issues. The 18 randomized controlled trials in this sample were critically evaluated for design quality, leading to the conclusion that they consistently demonstrated strong effect sizes and other positive statistical results that far exceed chance after relatively few treatment sessions. Criteria for evidence-based treatments proposed by Division 12 of the American Psychological Association were also applied and found to be met for a number of conditions, including PTSD."
