Abstract
Background Since the turn of the century, Emotional Freedom Techniques (EFT) has come into widespread use in medical and psychological treatment settings. It is also used as self-help by tens of millions of people each year. Clinical EFT, the manualized form of the method, has been validated as an "evidence-based" practice using criteria published by the American Psychological Association (APA) Division 12 Task Force on Empirically Validated Therapies. Its three essential ingredients are exposure, cognitive framing, and acupressure. Objectives In 2013 we published a paper defining Clinical EFT and reviewing published research. It has been viewed or downloaded over 36,000 times, indicating widespread interest in this treatment modality. Here we update our findings based on subsequently published literature and propose directions for future research. Method We performed a systematic review of the literature to identify randomized controlled trials (RCTs) and meta-analyses. Retrieval of 4,167 results resulted in the identification of 56 RCTs (n = 2,013), 41 of which were published subsequent to our earlier review, as well as eight meta-analyses. Results RCTs have found EFT treatment to be effective for (a) psychological conditions such as anxiety, depression, phobias, and posttraumatic stress disorder (PTSD); (b) physiological issues such as pain, insomnia, and autoimmune conditions; (c) professional and sports performance; and (d) biological markers of stress. Meta-analyses evaluating the effect of EFT treatment have found it to be "moderate" to "large." Successful independent replication studies have been carried out for anxiety, depression, PTSD, phobias, sports performance, and cortisol levels. We outline the next steps in EFT research. These include determining its impact on cancer, heart disease, diabetes, and cognitive impairment; analysis of the large-scale datasets made possible by mobile apps; and delivery through channels such as virtual practitioner sessions, artificial intelligence agents, online courses, apps, virtual reality platforms, and standardized group therapy. Conclusions Subsequent research has confirmed the conclusions of earlier studies. These find Clinical EFT to be efficacious for a range of psychological and physiological conditions. Comparatively few treatment sessions are required, treatment is effective whether delivered in person or virtually, and symptom improvements persist over time. Treatment is associated with measurable biological effects in the dimensions of gene expression, brain synchrony, hormonal synthesis, and a wide range of biomarkers. Clinical EFT is a stable and mature method with an extensive evidence base. Its use in primary care settings as a safe, rapid, reliable, and effective treatment for both psychological and medical diagnoses continues to grow.

J Evid Based Integr Med 2019; 24:2515690X18823691. [PMID: 30777453 PMCID: PMC6381429 DOI: 10.1177/2515690x18823691] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 11/05/2018] [Accepted: 12/17/2018] [Indexed: 11/17/2022] Open
Abstract
Emotional Freedom Technique (EFT) is an evidence-based self-help therapeutic method and over 100 studies demonstrate its efficacy. However, information about the physiological effects of EFT is limited. The current study sought to elucidate EFTs mechanisms of action across the central nervous system (CNS) by measuring heart rate variability (HRV) and heart coherence (HC); the circulatory system using resting heart rate (RHR) and blood pressure (BP); the endocrine system using cortisol, and the immune system using salivary immunoglobulin A (SigA). The second aim was to measure psychological symptoms. Participants (N = 203) were enrolled in a 4-day training workshop held in different locations. At one workshop (n = 31), participants also received comprehensive physiological testing. Posttest, significant declines were found in anxiety (-40%), depression (-35%), posttraumatic stress disorder (-32%), pain (-57%), and cravings (-74%), all P < .000. Happiness increased (+31%, P = .000) as did SigA (+113%, P = .017). Significant improvements were found in RHR (-8%, P = .001), cortisol (-37%, P < .000), systolic BP (-6%, P = .001), and diastolic BP (-8%, P < .000). Positive trends were observed for HRV and HC and gains were maintained on follow-up, indicating EFT results in positive health effects as well as increased mental well-being.

Abstract
Metabolomics is used to assess the compliance and bioavailability of food components, as well as to evaluate the metabolic changes associated with food consumption. This study aimed to analyze the effect of consuming ready-to-eat meals containing a cocoa extract, within an energy restricted diet on urinary metabolomic changes. Fifty middle-aged volunteers [30.6 (2.3) kg m(-2)] participated in a 4-week randomised, parallel and double-blind study. Half consumed meals supplemented with 1.4 g of cocoa extract (645 mg polyphenols) while the remaining subjects received meals without cocoa supplementation. Ready-to-eat meals were included within a 15% energy restricted diet. Urine samples (24 h) were collected at baseline and after 4 weeks and were analyzed by high-performance-liquid chromatography-time-of-flight-mass-spectrometry (HPLC-TOF-MS) in negative and positive ionization modes followed by multivariate analysis. The relationship between urinary metabolites was evaluated by the Spearman correlation test. Interestingly, the principal component analysis discriminated among the baseline group, control group at the endpoint and cocoa group at the endpoint (p < 0.01), although in the positive ionization mode the baseline and control groups were not well distinguished. Metabolites were related to theobromine metabolism (3-methylxanthine and 3-methyluric acid), food processing (L-beta-aspartyl-L-phenylalanine), flavonoids (2,5,7,3',4'-pentahydroxyflavanone-5-O-glucoside and 7,4'-dimethoxy-6-C-methylflavanone), catecholamine (3-methoxy-4-hydroxyphenylglycol-sulphate) and endogenous metabolism (uridine monophosphate). These metabolites were present in higher (p < 0.001) amounts in the cocoa group. 3-Methylxanthine and l-beta-aspartyl-L-phenylalanine were confirmed with standards. Interestingly, 3-methoxy-4-hydroxyphenylglycol-sulphate was positively correlated with 3-methylxanthine (rho = 0.552; p < 0.001) and 7,4'-dimethoxy-6-C-methylflavanone (rho = 447; p = 0.002). In conclusion, the metabolomic approach supported the compliance of the volunteers with the intervention and suggested the bioavailability of cocoa compounds within the meals.

Abstract
Prior research indicates elevated but subclinical posttraumatic stress disorder (PTSD) symptoms as a risk factor for a later diagnosis of PTSD. This study examined the progression of symptoms in 21 subclinical veterans. Participants were randomized into a treatment as usual (TAU) wait-list group and an experimental group, which received TAU plus six sessions of clinical emotional freedom techniques (EFT). Symptoms were assessed using the PCL-M (Posttraumatic Checklist-Military) on which a score of 35 or higher indicates increased risk for PTSD. The mean pretreatment score of participants was 39 ± 8.7, with no significant difference between groups. No change was found in the TAU group during the wait period. Afterward, the TAU group received an identical clinical EFT protocol. Posttreatment groups were combined for analysis. Scores declined to a mean of 25 (-64%, P < .0001). Participants maintained their gains, with mean three-month and six-month follow-up PCL-M scores of 27 (P < .0001). Similar reductions were noted in the depth and breadth of psychological conditions such as anxiety. A Cohen's d = 1.99 indicates a large treatment effect. Reductions in traumatic brain injury symptoms (P = .045) and insomnia (P = .004) were also noted. Symptom improvements were similar to those assessed in studies of PTSD-positive veterans. EFT may thus be protective against an increase in symptoms and a later PTSD diagnosis. As a simple and quickly learned self-help method, EFT may be a clinically useful element of a resiliency program for veterans and active-duty warriors.

Abstract
The Emotional Freedom Technique (EFT) is defined and described as a clinical procedure for the relief of psychological and physical distress that patients often bring to the attention of nurses. Frequently referred to as "tapping," this technique combines the cognitive reprocessing benefits of exposure and acceptance therapy with the energetic disturbance releases associated with acupuncture and other energy therapies. More than 60 research articles in peer-reviewed journals report a staggering 98% efficacy rate with the use of this procedure from psychological distress (posttraumatic stress disorder, phobias, anxiety, depression, etc.) to physical conditions (asthma, fibromyalgia, pain, seizure disorders, etc.) to performance issues (athletic, academic). Perhaps because of this, this technique has encountered a fair degree of skepticism within the health care community. Easily taught as a self-help aid that patients can administer to themselves, EFT becomes an efficacious tool in the hands of nurses who are seeking whole person approaches for the healing of a wide variety of psychological and physical conditions. A conceptual framework, mechanisms of action, evidence of safety, literature review, and case studies are also included.

An Increase in Plasma Homovanillic Acid with Cocoa Extract Consumption Is Associated with the Alleviation of Depressive Symptoms in Overweight or Obese Adults on an Energy Restricted Diet in a Randomized Controlled Trial. J Nutr 2015; 146:897S-904S. [PMID: 26962189 DOI: 10.3945/jn.115.222828] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Revised: 10/08/2015] [Accepted: 12/08/2015] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Obesity has been associated with various health disorders, including psychological alterations. Cocoa consumption and weight management may produce a beneficial effect on these problems. OBJECTIVE The purpose of this study was to investigate the effect of cocoa extract supplementation as part of an energy-restricted diet on psychological status and peripheral dopaminergic activity in overweight or obese middle-aged subjects. METHODS In a 4-wk, double-blind, randomized, placebo-controlled parallel nutritional intervention, 22 men and 25 women [mean ± SD age: 57 ± 5 y; body mass index (kg/m2): 30.6 ± 2.3] were studied. After a 1-wk run-in period, volunteers consumed 15% energy-restricted diets; one-half of the volunteers were randomly assigned to receive ready-to-eat meals supplemented with 1.4 g cocoa extract/d (645 mg total polyphenols/d), whereas the rest of the volunteers received the same meals without cocoa supplementation. Plasma monoamines [dopamine, dopac, and homovanillic acid (HVA)], monoamine oxidase (MAO), and psychological status (anxiety and depressive symptoms) were analyzed in fasting participants at baseline and endpoint. Data were analyzed over time, and regression and correlation analyses were conducted to determine the relation between variables. RESULTS Depressive symptoms decreased in both groups after the intervention (control: -9.4%, P < 0.001; cocoa: -6.3%, P = 0.008), but anxiety symptoms did not. The increase in plasma HVA was 11.5% greater in the cocoa group than in the control group (P = 0.016), but plasma dopamine, dopac, and MAO changes did not differ between groups. A negative relation between changes in depressive symptoms and changes in plasma HVA was observed in the cocoa group (β = -0.39, P = 0.029). Moreover, the change in plasma dopamine was positively associated with the change in methyl-catechin-O-glucoronide in the cocoa-supplemented group (r = 0.69, P = 0.019). CONCLUSION The intake of cocoa extract by participants consuming a 15% energy-restricted diet contributed to an increase in plasma HVA concentrations. This change was associated with a reduction in depressive symptoms, suggesting a potential effect of cocoa extract intake on this relation. The present results are secondary analyses of a clinical trial that was registered at www.clinicaltrials.gov as NCT01596309.
