Introduction
A number of systematic reviews consider the evidence for Emotional Freedom Techniques (EFT) as an “evidence-based” practice.
1–3 Studies are typically evaluated using criteria published by the American Psychological Association’s (APA’s) Division 12 Task Force on Empirically Validated Treatments, hereafter abridged as “APA standards.”
4–6 The APA standards amalgamate current scientific consensus to identify 7 “essential” criteria that must be present for a study to qualify: randomization, sample size sufficient to establish statistical significance, a clear definition of the treatment population, valid and reliable assessments, blind interview assignments, a treatment manual, and sufficient data to allow the study’s statistical methods to be assessed for appropriateness.
1–3 A minimum of 2 randomized controlled trials (RCTs) are required for a therapeutic method to be deemed “efficacious.”
When proposing its own standards, the US Food and Drug Administration contemporaneously set a similar standard of 2 RCTs for drug trials.
7 A systematic review searching the scientific literature until April 2012 found 51 studies of EFT and allied methods collectively referred to as energy psychology. It found that “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.”
1A systematic review and meta-analysis of 7 studies of EFT for posttraumatic stress disorder (PTSD) was recently reported.
8 It used the Cohen difference, an appropriate effect size for the comparison between 2 means, in which 0.2 indicates a treatment effect, 0.5 indicates a moderate treatment effect, and 0.8 indicates a large treatment effect. The meta-analysis found a large treatment effect, with a
d of 2.96 when EFT was compared with normal care. Compared with eye movement desensitization and reprocessing (EMDR) and cognitive behavior therapy (CBT), no significant treatment difference was found, indicating similarities in efficacy between the 3 treatments. Two other systematic reviews with meta-analyses, 1 for anxiety (14 RCTs) and 1 for depression (20 RCTs and within-subjects studies), found “large” treatment effect sizes of 1.23 and 1.31, respectively.
9,10 Authors of all 3 meta-analyses used the APA standards as their quality-control criteria when selecting studies for inclusion. An online database of EFT research lists more than 100 clinical trials (
www.Research.EFTuniverse.com).
A psychophysiologic intervention, EFT draws from 2 established therapies: CBT and exposure therapy. It adds the novel component of somatic stimulation using acupuncture points (“acupoints”). Developed in the early 1990s, EFT is described in subsequent editions of a standardized manual.
11,12 Clients are asked to assess the intensity of traumatic events before and after EFT using the Wolpe Subjective Units of Distress (SUD) measure,
13 an 11-point Likert scale ranging from 0 (no distress) to 10 (maximum distress). During a typical treatment session, clients recall a traumatic event and pair it with a statement of self-acceptance, such as “Even though I experienced [name of the event] I deeply and completely accept myself.” They stimulate 7 acupuncture points with their fingertips (acupressure) by tapping on them or rubbing them while repeating the name of the event. If their SUD score is still high, they might describe the event in detail. An optional supplemental technique is called the 9 Gamut procedure and uses eye movements similar to those employed in EMDR. Often EFT is taught by therapists, physicians, nurses, and life coaches to patients as a method of self-care to use between treatment sessions. The method and typical applications are fully described elsewhere in the literature.
2,3To differentiate the acupressure component from the cognitive and exposure elements that EFT shares with other therapies, a meta-analysis examined six dismantling studies.
14 While retaining the cognitive and exposure parts of EFT, these six studies used control groups that either substituted an active treatment such as diaphragmatic breathing for acupressure or used pressure on sham acupoints. The meta-analysis found a large treatment difference between the groups that used authentic acupoints vs controls, indicating that acupressure is an active treatment ingredient in EFT’s protocol and not merely an inert component.
Many studies conducted by independent research teams using a variety of different population samples, including veterans, adolescents, refugees, and disaster survivors, demonstrate the efficacy of acupressure stimulation as a treatment of PTSD.
15–23 In a typical RCT of veterans who met clinical criteria for PTSD (N
= 59) and were assessed against a control group receiving treatment as usual (TAU), 86% of participants no longer met the criteria for PTSD after 6 sessions of EFT (p < 0.0001).
15 The military version of the Posttraumatic Stress Disorder Checklist (PCL-M),
24 a valid and reliable 17-item tool on which a score of 50 indicates the likelihood of a PTSD diagnosis, was used to assess symptoms. Mean PCL-M scores were 61.4 before treatment and 34.6 on posttreatment test. A replication of this study by an independent research team demonstrated similar results.
18A hospital in the United Kingdom’s National Health Service conducted a study of a PTSD-positive outpatient population (N = 46) comparing EFT with EMDR and a waiting list with usual care.
17 They found both EFT and EMDR to remediate PTSD in a mean of 4 sessions (p < 0.001). An RCT of abused male adolescents (N = 16) used the Impact of Events Scale
25 to evaluate participant distress. Scores declined from 36 to 3 (p < 0.001) after a single EFT session.
16 Another RCT (N = 21) examined the impact of EFT on resiliency in veterans at risk of PTSD.
26 Six sessions produced a reduction in symptoms comparable to the results noted in a clinical population (p < 0.0001). Gains were maintained on follow-up in all 4 studies, whereas the wait-list participants did not improve.
16–18,26A systematic review of the literature includes 12 studies in which EFT demonstrated efficacy for a range of psychological conditions, such as PTSD, depression, and anxiety when delivered in the form of group therapy.
2 A written protocol called Borrowing Benefits, describing how to use EFT in groups, has been tested in both RCTs and outcomes studies.
12 In an uncontrolled study with veterans and their spouses, 218 participants were evaluated for PTSD symptoms before and after a 7-day retreat in which they used Borrowing Benefits and other EFT techniques.
27 Of the veterans, 83% exhibited clinical symptom levels on pretest, as did 29% of their spouses. On follow-up, only 28% of veterans and 4% of spouses still met the clinical cutoff (p < 0.001).
27 The Borrowing Benefits technique is described in detail in the EFT manual.
12 In a group, the practitioner works with one individual while witnesses self-apply EFT to their own personal issues. Studies of Borrowing Benefits find it efficacious for a wide variety of psychological conditions.
2Clinicians widely practice EFT and similar techniques. A recent survey critical of the method solicited responses from licensed psychotherapists using Listservs such as Acceptance and Commitment Therapy, the Society for a Science of Clinical Psychology, and the Association for Behavioral and Cognitive Therapies.
28 It found that 42% of therapists were using these modalities.
The Veterans Stress Project
29 is a charitable program of the National Institute for Integrative Healthcare that has served as a recruitment vehicle for several studies. Its Web site (
www.StressProject.org) serves as a clearinghouse, allowing veterans to locate practitioners. The Veterans Stress Project also hosts an interactive virtual EFT coaching software program called Battle Tap and archives numerous testimonials from veterans who have used Battle Tap, individual therapy, and group EFT therapy to support their recovery from PTSD. These and other private and public initiatives pair veterans seeking treatment with practitioners offering EFT and similar therapeutic methods.
The objective of the current research was to develop clinical best practice guidelines for the use of EFT to treat PTSD. Toward that end, we evaluated practitioner experience and the published literature to arrive at a consensus statement.
Methods
We undertook a survey of practitioners using EFT to treat PTSD (
www.surveymonkey.com/s/GTZXD2B; SurveyMonkey, Palo Alto, CA). The goals of the survey were to develop a demographic profile of practitioners, to evaluate how EFT is used in professional settings, and to determine current practices for PTSD treatment. Drawing on the results, the evidence base, and case histories, we formulated clinical guidelines for the use of EFT in the treatment of veterans and military personnel, with the “stepped care” model used by the National Institute for Health and Clinical Excellence (NICE) in the United Kingdom as our framework.
The invitation to complete the survey was extended in February 2014 by several US and United Kingdom organizations: the National Institute for Integrative Healthcare, the Association for Comprehensive Energy Psychology, and the Association for Meridian and Energy Therapies, as well as informal networks of practitioners. We received responses from 448 practitioners. The number of those responding to each question is indicated in
Tables 1 to
5. Some survey questions allowed practitioners to select more than 1 option. For example, a practitioner could select both “nurse” and “retired” or for professional settings both “private practice” and “medical center”; thus; the number of responses to these questions exceeded 448.
One item asked practitioners to estimate how many sessions were required to treat complex PTSD (C-PTSD). Although C-PTSD does not appear as a diagnosis separate from PTSD in current diagnostic manuals, C-PTSD has been the subject of a great deal of debate in the clinical community. It is scheduled to appear in the upcoming edition of the World Health Organization’s (WHO)
International Statistical Classification of Diseases and Related Health Problems.30 Usually, C-PTSD is defined as repetitive and prolonged trauma, such as that which can occur in a war zone, in cases of child abuse, or in domestic violence situations. It is regarded as more difficult to treat than single-incident PTSD.
Results
Table 1 summarizes the demographic characteristics of the 448 respondents. Most respondents were either licensed mental health professionals (37.7%) or alternative medicine practitioners (31.6%). More than 62% held a master’s degree or higher, and 84.5% reported practicing in a private practice setting. The percentage of practitioners with 10 or fewer years of experience was 32.8%, 11 to 20 years was 26.8%, 21 to 30 years was 18.2%, 31 to 40 years was 15.9%, and 41 or more years in practice was 6.2%. Respondents had a mean age of 58 years, with a range of 22 to 85 years, and 72.4% were women.
Table 2 profiles the course of treatment for PTSD-positive clients. The PTSD clients constituted more than 20% of the practice for 37.0% of practitioners and less than 10% for 39.9% of respondents. Nearly half the respondents (45.2%) reported having worked with more than 50 clients with PTSD, and 41.4% said they spend more than 5 hours per week treating PTSD. Estimates of the average number of sessions needed to successfully treat complex PTSD were in the 1 to 5 range for 25.7% of the practitioners and 6 to 10 sessions for an additional 37.3% of practitioners. These estimates of sessions required align with those in the published literature.
15–23 Table 3 summarizes responses regarding the perceived prevalence of PTSD, the use of diagnostic scales, and referrals. According to the US National Institutes of Health, the prevalence of PTSD in the general adult population is 3.5%,
31 but 91.7% of our survey respondents believed that this estimate is too low; only 7.6% assessed it as accurate. When asked to estimate the true prevalence, answers varied widely, but the most common answers were 6% to 10% (24.1%), 11% to 15% (19.7%), and 16% to 20% (18.2%).
Validated instruments to track client progress were used by 29.3% of respondents, which is consistent with other surveys of mental health professionals.
32 Of the 448 respondents, 153 reported which assessments they use. The PTSD Checklist (PCL) was the most common, used by 56.9%, followed by the Life Events Checklist (36.6%) and the PTSD Symptom Scale (30.7%).
Practitioners rarely terminated work with a client and referred that client to another practitioner. For 91.8% of respondents, this occurred with 10% or fewer of clients. Continuing treatment in conjunction with another professional was more common.
Table 4 summarizes the most used therapy techniques, both EFT and non-EFT. Regarding use of EFT, 43.6% indicated they use it 51% or more of the time during their therapy sessions, and 27.4% said they use EFT 21% to 50% of the time. The 3 most common non-EFT methods used are cognitive therapy (45.7% of practitioners surveyed), life coaching (39.8%), and EMDR (31%). In an open-ended question, the non-EFT techniques that respondents listed as most beneficial for treating PTSD were cognitive therapy (12.0%), EMDR (10.2%), and meditation (7.7%).
Table 5 summarizes respondents’ evaluations of PTSD therapy outcomes. Full rehabilitation in more than 60% of their clients was reported by 64.7% of respondents, with full rehabilitation in 90% of their clients being reported by 22.1% of respondents. Clinical trials of EFT in treating PTSD
15–23 show higher success rates than those most frequently reported by the respondents. Most respondents (89.8%) reported that less than 10% of their clients make little or no progress with EFT. This is reflected in the low dropout rates typical of EFT treatment programs; in the 7 studies reported in the meta-analysis of EFT for PTSD, the mean dropout rate was under 10%.
8 We now present two typical case studies of veterans who presented for treatment at Veterans Affairs facilities and exhibited positive outcomes.
Case Study 1: Vietnam Combat Memories
More than four decades after returning from service in Vietnam, a male veteran presented for treatment. His issues included complex medical problems, multiple addictions, broken relationships, intolerable mental and emotional symptoms, nightmares, and homelessness. As one component of a multidisciplinary evidence-based treatment regimen at the Veterans Affairs Medical Center, he chose to learn and practice EFT as an adjunct to individual psychotherapy and group therapy.
During one appointment, he chose to use EFT on three persistent Vietnam combat memories that induced hyperarousal, reexperiencing, and avoidance. In the first, he was faced with an approaching enemy unit. In the second, his unit was attacked and most of his “battle buddies” were killed. In the third, he witnessed another adolescent warrior’s life-threatening wounds and emotional suffering.
He provided an SUD score of 10 of 10 for the first 2 memories at the start of an hourlong appointment. After EFT, this fell to 0. He commented, “It’s over. I’m home now. I’m safe.” By the time he felt ready to apply EFT to the third memory, he reported distress already reduced to 3 and, after EFT, 0. He appeared animated and chose to retell the stories, sharing graphic details without any evidence or report of emotional distress. He demonstrated positive cognitive shifts, reframing his perception to reflect that his quick actions under fire did not reflect cowardice, as he had believed since the incident, but rather that he had quickly done exactly what he was trained to do; this saved his own life and the lives of others. He smiled and laughed and reported immense relief, energy, and joy. By the following appointment, he reported that he had not had a single nightmare about Vietnam that week, for the first time in more than 40 years.
He continues to experience sustained symptom relief. He now has spent three years in recovery from substance abuse, the longest period yet. Veterans Affairs clinicians are gradually weaning him off his psychotropic medications. He uses EFT independently between appointments for sustained smoking cessation, ongoing healthy weight loss, and stress management. He has found stable housing and renewed healthy relationships with his family. He wants clinicians and other veterans to know this: “I was in a fight for my life. Don’t give up. Keep trying. EFT helped me to cope with life. It relaxes me and puts me in a place where I want to be: from the inside looking out, not the outside looking in. It’s given me a positive perspective on life. I have my family back, my mind got clearer, and I have more confidence. It’s lovely.”
Case Study 2: Military Sexual Trauma
When he came for treatment, this veteran was experiencing intolerable emotional, mental, and physical symptoms. He had been numbing these by self-medicating with multiple illicit substances for more than 30 years. He was homeless, with broken relationships and medical problems. Although skeptical about EFT “because it gave me the impression of being silly,” he decided to try it. He states, “After a few sessions, with practice, I began to notice how I was able to release the distress and fears caused by old and new painful emotions. … One of its advantages [is] that I can and would utilize it at home, in school, or on the job as a form of relaxation.”
Initially, he was reluctant to address his experience with military sexual trauma using any psychotherapeutic modality. He had already dropped out of other evidence-based modalities before trying EFT, stating that sessions were like “experiencing it all over again.” During one appointment, he chose to use EFT on his military sexual trauma experience, stating that it was blocking him from moving forward in his life. During the next four EFT appointments, he achieved resolution of his distressful symptoms. The positive effect persisted for the following year as he was weaned from his psychotropic medications.
During an EFT session, a defining moment occurred when he was stuck at a persistent level of emotional distress, a 5 to 6 on the SUD scale. He used EFT on a particular aspect of his sexual trauma experience, “the look on their faces.” (For a discussion of “Aspects,” see
The EFT Manual, p 100
12). Once his SUD score fell to 0, he stated: “It doesn’t matter now. I don’t have to live my life this way anymore. It’s over. I know it happened, but I can think about it now without feeling those symptoms or wanting to go out and use [illegal substances]. I’m at peace now. I feel as if the weight of the world has been lifted off my shoulders.” The clinician observed positive cognitive shifts, relaxed facial and body posture, and smiles in support of his comments.
This veteran has now achieved more than five years in recovery from substance abuse, his longest time ever. His PTSD symptoms are resolved. He is enjoying healthy relationships with family and friends. He is independent, living in his own apartment, attending classes with the goal of employment, and experiencing a positive quality of life. He continues to use acupuncture, meditation, and EFT. He wants clinicians and other veterans to know this: “These techniques have given me a new outlook on life and to see new possibilities in the hope of setting goals and to visualize stability in my life, free of tension. Most of all it has helped me to accept my faults, forgive myself and others, to make amends, and change my negative feelings and behaviors into positive ones, giving me a sense of peace, lots of joy, and much love and compassion for others.”
