The Effect of Emotional Freedom Techniques on Stress Biochemistry: A Randomized Controlled Trial
Church, Dawson PhD*; Yount, Garret PhD†; Brooks, Audrey J. PhD‡
Abstract
Abstract: This study examined the changes in cortisol levels and psychological distress symptoms of 83 nonclinical subjects receiving a single hourlong intervention. Subjects were randomly assigned to either an emotional freedom technique (EFT) group, a psychotherapy group receiving a supportive interviews (SI), or a no treatment (NT) group. Salivary cortisol assays were performed immediately before and 30 minutes after the intervention. Psychological distress symptoms were assessed using the symptom assessment-45. The EFT group showed statistically significant improvements in anxiety (−58.34%, p < 0.05), depression (−49.33%, p < 0.002), the overall severity of symptoms (−50.5%, p < 0.001), and symptom breadth (−41.93%, p < 0.001). The EFT group experienced a significant decrease in cortisol level (−24.39%; SE, 2.62) compared with the decrease observed in the SI (−14.25%; SE, 2.61) and NT (−14.44%; SE, 2.67) groups (p < 0.03). The decrease in cortisol levels in the EFT group mirrored the observed improvement in psychological distress.

Abstract
Cortisol is a physiological marker for stress. Elevated cortisol levels are associated with accelerated aging, many organic diseases, and psychological conditions such as depression and anxiety. This study examined the changes in cortisol levels and psychological symptoms of 83 non-clinical subjects receiving a single hour-long intervention. Subjects were randomly assigned to either an EFT group, a psychotherapy group receiving a supportive interview (SI), or a no treatment (NT) group. Salivary cortisol assays were performed immediately before, and thirty minutes after the intervention. Psychological conditions were assessed using the SA-45. The EFT group showed clinically and statistically significant improvements in anxiety (-58.34%, p < .05), depression (-49.33%, p < .002), the overall severity of symptoms, (-50.5%, p < .001), and symptom breadth across conditions (-41.93%, p < .001). There were no significant changes in cortisol levels between SI (-14.25%, SE 2.61) and NT (-14.44%, SE 2.67); however cortisol in the EFT group dropped significantly (-24.39%, SE 2.62) compared to SI and NT (p < .01). The reduced cortisol levels in the EFT group correlated with decreased severity in psychological symptoms as measured by the SA-45. These results suggest that salivary cortisol tests may be useful not only for assessing stress physiology, but also as an objective indicator of the impact of mental health treatments in reducing psychological symptoms. In the current study, EFT was shown to significantly improve both cortisol-related stress levels and self-reported psychological symptoms after a single treatment session.

The Effect of a Brief EFT (Emotional Freedom Techniques) Self-Intervention on Anxiety, Depression, Pain and Cravings in Healthcare Workers
Dawson Church, PhD & Audrey J. Brooks, PhD
Integrative Medicine: A Clinician’s Journal, (2010), Oct/Nov.
Abstract
This study examined whether self-intervention with Emotional Freedom Techniques (EFT), a brief exposure therapy that combines a cognitive and a somatic element, had an effect on healthcare workers’ psychological distress symptoms. Participants were 216 attendees at 5 professional conferences. Psychological distress, as measured by the SA-45, and self-rated pain, emotional distress, and craving were assessed before and after 2-hours of self-applied EFT, utilizing a within-subjects design. A 90-day follow-up was completed by 53% of the sample with 61% reporting using EFT subsequent to the workshop. Significant improvements were found on all distress subscales and ratings of pain, emotional distress, and cravings at posttest (all p<.001). Gains were maintained at follow-up for most SA-45 scales. The severity of psychological symptoms was reduced (-45%, p<.001) as well as the breadth (-40%, p<.001), with significant gains maintained at follow-up. Greater subsequent EFT use correlated with a greater decrease in symptom severity at follow-up (p<.034, r=.199), but not in breadth of symptoms (p<.0117, r=.148). EFT provided an immediate effect on psychological distress, pain, and cravings that was replicated across multiple conferences and healthcare provider samples.

Psychological Symptom Change in Veterans After Six Sessions of Emotional Freedom Techniques (EFT); An Observational Study
Dawson Church, PhD, Linda Geronilla, PhD, & Ingrid Dinter
International Journal of Healing and Caring, (2009, January), 9(1).
Abstract
Protocols to treat veterans with brief courses of therapy are required, in light of the large numbers returning from Iraq and Afghanistan with depression, anxiety, PTSD and other psychological problems. This observational study examined the effects of six sessions of EFT on seven veterans, using a within-subjects, time-series, repeated measures design. Participants were assessed using a well-validated instrument, the SA-45, which has general scales measuring the depth and severity of psychological symptoms. It also contains subscales for anxiety, depression, obsessive-compulsive behavior, phobic anxiety, hostility, interpersonal sensitivity, paranoia, psychosis, and somatization. Participants were assessed before and after treatment, and again after 90 days. Interventions were done by two different practitioners using a standardized form of EFT to address traumatic combat memories. Symptom severity decreased significantly by 40% (p<.001), anxiety decreased 46% (p<.001), depression 49% (p<.001), and PTSD 50% (p<.016). These gains were maintained at the 90-day follow-up.

Daniel J. Benor, Karen Ledger, Loren Toussaint, Greg Hett, & David Zaccaro.
Explore: The Journal of Science and Healing, (2009, November) 5(6), 338-340.
Objective: This study explored test anxiety benefits of Wholistic Hybrid derived from EMDR (WHEE), Emotional Freedom Techniques (EFT), and Cognitive Behavioral Therapy.
Participants: Canadian university students with severe or moderate test anxiety participated.
Methods: A double-blind, controlled trial of WHEE (n = 5), EFT (n =5), and CBT (n = 5) was conducted. Standardized anxiety measures included: the Test Anxiety Inventory (TAI) and Hopkins Symptom Checklist (HSCL-21).
Results: Despite small sample size, significant reductions on the TAI and HSCL-21 were found for WHEE; on the TAI for EFT; and on the HSCL-21 for CBT. There were no significant differences between the scores for the three treatments. In only two sessions WHEE and EFT achieved the equivalent benefits to those achieved by CBT in five sessions. Participants reported high satisfaction with all treatments. EFT and WHEE students successfully transferred their self-treatment skills to other stressful areas of their lives.
Conclusions: WHEE and EFT show promise as effective treatments for test anxiety.

Energy Psychology: Theory, Research & Treatment, (2008), (1)1, 23-30/
Abstract
This study investigated the effect of Emotional Freedom Techniques (EFT) and Progressive Muscular Relaxation (PMR) on test anxiety. A group of 312 high school students enrolled at a private academy were evaluated using the Test Anxiety Inventory (TAI), which contains Worry and Emotionality subscales. Scores for 70 students demonstrated high levels of test anxiety; these students were randomized into control and experimental groups. During a single treatment session, the control group received instruction in PMR and the experimental group in EFT, which was followed by self-treatment at home. After 2 months, subjects were retested using the TAI. Repeated covariance analysis was performed to determine the effects of EFT and PMR on the mean TAI score, as well as the 2 subscale scores. Each group completed a sample examination at the beginning and end of the study, and their mean scores were computed. Thirty-two of the initial 70 subjects completed all the study’s requirements, and all statistical analyses were done on this group. A statistically significant decrease occurred in the test anxiety scores of both the experimental and control groups. The EFT group had a significantly greater decrease than the PMR group (p < .05). The scores of the EFT group were lower on the Emotionality and Worry subscales (p < .05). Both groups scored higher on the test examinations after treatment. Although the improvement was greater for the EFT group, the difference was not statistically significant.

Self-administered EFT (Emotional Freedom Techniques) in Individuals with Fibromyalgia: A Randomized Trial
Gunilla Brattberg, MD, School of Medicine, Lund University, Sweden
Integrative Medicine: A Clinician’s Journal, (2008), Aug/Sep, 30-35.
Abstract
The aim of this study was to examine if self-administered EFT (Emotional Freedom Techniques) leads to reduced pain perception, increased acceptance, coping ability and health-related quality of life in individuals with fibromyalgia. 86 women, diagnosed with fibromyalgia and on sick leave for at least 3 months, were randomly assigned to a treatment group or a waiting list group. An eight-week EFT treatment program was administered via the Internet.
Upon completion of the program, statistically significant improvements were observed in the intervention group (n=26) in comparison with the waiting list group (n=36) for variables such as pain, anxiety, depression, vitality, social function, mental health, performance problems involving work or other activities due to physical as well as emotional reasons, and stress symptoms. Pain catastrophizing measures, such as rumination, magnification and helplessness, were significantly reduced, and the activity level was significantly increased. The number needed to treat (NNT) regarding recovering from anxiety was 3. NNT for depression was 4.
Self-administered EFT seems to be a good complement to other treatments and rehabilitation programs. The sample size was small and the dropout rate was high. Therefore the surprisingly good results have to be interpreted with caution. However, it would be of interest to further study this simple and easily accessible self-administered treatment method, which can even be taught over the Internet.
The Effects of EFT on Long-term Psychological Symptoms
Rowe, J.
Counseling and Clinical Psychology Journal, 2(3):104. (2005)
Abstract
Previous research (Salas, 2000; Wells, et al., 2003), theoretical writings (Arenson, 2001, Callahan, 1985, Durlacher, 1994, Flint, 1999, Gallo, 2002, Hover-Kramer, 2002, Lake & Wells, 2003, Lambrou & Pratt, 2000, and Rowe, 2003), and many case reports have suggested that energy psychology is an effective psychotherapy treatment that improves psychological functioning. The purpose of the present study was to measure any changes in psychological functioning that might result from participation in an experiential Emotional Freedom Techniques (EFT) workshop and to examine the long-term effects. Using a time-series, within-subjects repeated measures design, 102 participants were tested with a short-form of the SCL-90-R (SA-45) 1 month before, at the beginning of the workshop, at the end of the workshop, 1 month after the workshop, and 6 months after the workshop. There was a statistically significant decrease (p < .0005) in all measures of psychological distress as measured by the SA-45 from pre-workshop to post-workshop which held up at the 6 month follow-up.
Emotional Freedom Techniques (EFT) as an Effective Adjunctive Treatment in the Neurotherapeutic Treatment of Seizure Disorders
Paul Swingle, PhD.
Energy Psychology: Theory, Research, & Treatment, (2010), 2(1), 29-38.
Abstract
Neurotherapy, including brainwave biofeedback, has been found to be an effective treatment for seizure disorders. A principal component of this treatment is an increase in the amplitude of the Sensory Motor Rhythm (SMR) over the sensory motor cortex in the brain. Electroencephalographic (QEEG) assessment of brainwave activity indicated that Emotional Freedom Techniques (EFT) increased SMR amplitude. The present article reviews the research on the effects of components of the EFT procedure on brainwave functioning that have been found to be beneficial in the treatment of seizure disorders.

Neurophysiological Indicators of EFT Treatment Of Post-Traumatic Stress
Swingle, P., Pulos, L., & Swingle, M. K.
Journal of Subtle Energies & Energy Medicine, (2005), 15, 75-86.
Description of Study:
This research study, conducted by Dr. Paul Swingle and his colleagues (Swingle, Pulos & Swingle, 2005), studied the effects of EFT on auto accident victims suffering from post traumatic stress disorder – an extremely disabling conditioning that involves unreasonable fears and often panic attacks, physiological symptoms of stress, nightmares, flashbacks, and other disabling symptoms. These researchers found that three months after they had learned EFT (in two sessions) those auto accident victims who reported continued significant symptom relief also showed significant positive changes in their brain waves. It was assumed that the clients showing the continued positive benefits were those who continued with home practice of self-administered EFT.
Abstract
Clients previously involved in a motor vehicle accident who reported traumatic stress associated with the accident received two sessions of Emotional Freedom Techniques (EFT) treatments. All clients reported improvement immediately following treatment. Brainwave assessments before and after EFT treatment indicated that clients who sustained the benefit of the EFT treatments had increased 13-15 Hz amplitude over the sensory motor cortex, decreased right frontal cortex arousal and an increased 3-7 Hz / 16-25 Hz ratio in the occiput. The benefits of psychoneurological research to reveal the processes of subtle energy healing are discussed.

A Re-Examination of Church’s (2009) Study into the Effects of Emotional Freedom Techniques (EFT) on Basketball Free-Throw Performance
A. Harvey Baker, PhD. Queens College, City University of New York.
Energy Psychology: Theory, Research, & Treatment, (2010), 2(1), 39-44.
Abstract
Church (2009) studied basketball free-throw performance of college varsity athletes, comparing (a) a brief treatment of Emotional Freedom Techniques (EFT) with (b) an encouraging talk. A re-examination of Church’s data supported his conclusion that the EFT treatment led to relatively better performance compared with the control group. In addition, we found (a) the reported improvement within the EFT condition was not significant, whereas the control condition decrement was significant and robust; (b) the positive effect of EFT thus took the form of an avoidance of the strong performance decrement seen in the control group; and (c) men and women contributed about equally to these findings. To avoid an apparent ceiling effect, future researchers should use a more difficult free-throw task. Because this apparent ceiling effect may have caused the distribution of scores to deviate from normality, we confirmed the above reported findings from parametric analyses using nonparametric tests.

The Effect of EFT (Emotional Freedom Techniques) on Athletic Performance: A Randomized Controlled Blind Trial
Dawson Church, PhD
Open Sports Sciences journal, (2009), 2, 94-99.
Abstract
The present study investigates the effect of a psychophysiological intervention, Emotional Freedom Techniques (EFT), on athletic performance. It evaluates whether a single EFT treatment can produce an improvement in high-performance men’s and women’s PAC-10 college basketball team members (n = 26). The treatment group received a 15 minute EFT session while a performance-matched attention control group received a placebo intervention of similar duration. Performance was measured on free throws and vertical jump height. The time frame of data collection and treatment simulated an actual basketball game. A statistically significant difference between the two groups was found for free throws (p<.03). On post-test, players who received the EFT intervention improved an average of 20.8%, while the attention control group decreased an average of 16.6%. There was no difference between treatment groups in jump height. When performance was analyzed separately by gender, trends toward significance were found for the women’s team on both performance measures with better results for the EFT intervention group. This indicates that EFT performed as an intervention during the course of an athletic event may improve free throw performance.
