Kwon, C. Y., Lee, B. · 2025
Hwa-Byung is a Korean condition rooted in suppressed anger that shows up as physical and emotional symptoms. This review pooled nine studies of six different therapies, one of which was EFT, and found that most approaches, including tapping, meaningfully eased Hwa-Byung symptoms. The reviewers were candid that the studies generally lacked strong control groups, so the evidence is suggestive rather than airtight.
Nine studies (7 controlled trials) of six intervention types, including emotional freedom technique, were reviewed; most interventions significantly improved Hwa-Byung symptoms versus waitlist or pre-post comparison, though methodological limitations including lack of appropriate control groups were noted.
Systematic review Preliminary
Suh, H-W., Choi, E-J., Kim, S-H. et al. · 2016
This review surveys 16 studies of Korean medicine approaches to Hwa-Byung, including acupuncture, herbal medicine, and EFT alongside other therapies. It found the field still needs more and better-controlled trials, with many existing studies weakened by a lack of blinding - a fair and honest limitation to note rather than hide.
Sixteen articles on traditional Korean medicine interventions for Hwa-Byung, including emotional freedom technique among other modalities, were reviewed; most non-pharmacological studies were judged at high risk of bias mainly due to lack of blinding.

Local Rwandan community leaders were taught a tapping technique and used it in single sessions with genocide survivors still living with trauma symptoms two decades later. Compared with survivors who didn't yet receive it, the tapping group's trauma symptoms dropped significantly more. Because local leaders delivered it rather than clinicians, this also speaks to how easily the technique can be taught to non-specialists.
Community leaders trained in Thought Field Therapy delivered one-time individual trauma interventions to 164 adult genocide survivors in a randomized controlled design; the treated group showed significantly greater reduction in trauma symptoms than the untreated group.

159 pregnant women in Turkey who had previously lost a pregnancy were split into three groups: tapping, listening to music, or no special support. Both the tapping group and the music group ended up doing better on measures of psychological growth and well-being, and had lower stress-hormone (cortisol) levels, than the group that got neither.
EFT and a music intervention, delivered separately to pregnant women with a prior prenatal loss, were both associated with greater psychological growth, higher well-being, and lower cortisol levels than the control group, per the study's stated conclusions.

120 women in labor at a Turkish hospital were split into three groups: tapping (EFT), a breathing-awareness technique, or usual care. Women who tapped reported less distress during the harder parts of labor and less fear about the birth afterward, compared with both other groups. It's a solid randomized study, though it looked only at a single labor experience rather than longer-term outcomes.
In this 3-arm RCT (EFT, breathing awareness, control), SUDS scores in the active and transition labor phases were significantly lower in the EFT group, and W-DEQ fear-of-childbirth scores differed significantly between groups (p<0.001); both EFT and breathing awareness helped, but EFT was found more effective.

116 first-time pregnant women in Iran were randomly assigned to 12 weeks of daily EFT tapping or no intervention. The tapping group's fear of childbirth dropped noticeably while the control group's fear actually crept up, and the difference held after delivery too. This is a solid randomized trial, though it relies on self-report questionnaires and was conducted in one country/clinic setting.
Fear of childbirth score decreased from 49.39 to 40.42 in the EFT group (p<0.0001) while the control group's score increased (p=0.002); postpartum fear scores were also significantly lower in the EFT group (27.13 vs 45.88, p<0.0001).

Brown, G., Batra, K., et al. · 2023
72 students used either a related technique called AIT or standard EFT to reduce distress about a bad memory, and both worked about equally well overall, though AIT users were more likely to feel fully better after just one round. This head-to-head randomized trial suggests EFT and AIT are similarly effective techniques.
Both interventions led to a significant drop in SUD scores (from over 4 to about 1); no statistically significant differences in post-intervention SUD or HRV between AIT and EFT; a significantly higher proportion using AIT achieved full elimination of negative emotion with just one round (47.4% vs 14.7%, p=0.012).

Seventy-two students originally randomized to either tapping (EFT) or a related technique called Advanced Integrative Therapy for a distressing memory were followed up six months later, and 51 responded. Both groups had kept their distress scores low and roughly equivalent to each other, meaning whichever technique someone got, the relief from that one memory held up half a year on. Because there's no untreated comparison group at follow-up, this shows the two techniques perform about the same as each other long-term, not that either beats doing nothing.
At six-month follow-up of a trial originally randomizing 72 participants to AIT or EFT (51 completed follow-up), there were no significant differences in SUD scores between groups (1.3 ± 0.6 for EFT vs 1.7 ± 0.5 for AIT, p=0.1), with both therapies maintaining low distress levels long-term.

This Colombian study combined EFT tapping with a recreational art-expression program for children living in shelters after suffering abuse, all of whom had post-traumatic stress. Nearly half the children who went through the combined tapping-and-art program no longer showed PTSD symptoms afterward, compared with about a quarter of the children in the comparison group. Because tapping was combined with an art program rather than tested alone, it's not possible to say how much of the benefit came from tapping specifically versus the art activities.
Post-intervention PTSD symptom scores differed significantly between groups (p=.002); 11 of 27 children (41%) in the experimental group no longer met PTSD symptom criteria, compared with 5 of 20 (25%) in the control group.

16 abused teenage boys in a court-ordered institution were randomized to a single EFT session or a waiting list. Every single teen who got EFT dropped to a non-clinical level of traumatic memory intensity, while the waiting group showed no change. This is a small but genuinely randomized study with a striking, consistent effect across all treated participants.
No improvement occurred in the wait list; posttest scores for all experimental group subjects improved to non-clinical on the total IES score (pre=36 SD±4.74, post=3 SD±2.60, p<0.001), as well as intrusive and avoidant symptom subscales and SUD.

Parents of autistic children in Israel and the US were randomly assigned to a real Thought Field Therapy stress protocol or a control tapping-like procedure. The TFT group reported less stress and more ability to see things from others' perspectives afterward, and this held over time. It's a mixed-model dissertation study, so replication in peer-reviewed literature would strengthen confidence.
Parents receiving the TFT stress reduction protocol showed reduced general stress and increased perspective-taking versus a control-stimulation protocol; parenting stress partially mediated the effect on perspective-taking, and gains held at follow-up.

Nearly 300 lay practitioners were given a brief training in a simplified tapping protocol and then used it in a single sitting with over 1,700 people in communities affected by war and trauma. On average, people's self-rated distress fell from roughly a 7.7 to a 2.5 out of 10 in that one session, a large and statistically real drop. There was no comparison group and no follow-up on whether the relief lasted, so this shows the technique can be taught fast and produce immediate relief at scale rather than proving lasting trauma recovery.
Across 1,722 individual single-session TTT applications delivered by 287 newly trained practitioners, mean self-rated distress (SUD, 0-10 scale) dropped from 7.69 pre-session to 2.5 post-session (p<.001).

Fifty Rwandan orphans still carrying PTSD symptoms 12 years after the genocide got one session of tapping therapy. Nearly all of them had scored above the PTSD cutoff beforehand; afterward, almost none did by their caregivers' ratings, and about four in five no longer did by their own. It's a single-session, uncontrolled study, so treat it as an early signal rather than definitive proof.
After a single Thought Field Therapy session, caregiver-rated PTSD-cutoff prevalence dropped from 100% to 6% and self-rated prevalence from 72% to 18% (p < .0001 on both measures).

Stone, B., Leyden, L., Fellows, B. · 2009
Forty-eight orphans at a Rwandan residential school, all carrying diagnosable PTSD from the genocide, went through a short tapping-based program over three days. Most who completed follow-up testing improved, and roughly a fifth improved enough to fall out of the clinical PTSD range entirely. This was an uncontrolled pilot with real dropout between pre- and post-testing, so it's best read as a promising first look, not proof.
Across three days of Thought Field Therapy sessions, the 34 orphans who completed post-testing showed an average 18.8% symptom reduction (p < .001), with a subgroup dropping below the clinical PTSD cutoff showing 53.7% average reductions.

In a real UK National Health Service clinic, 39 clients started and 31 completed a course of EFT for a range of emotional issues including anxiety, depression, and anger. Their overall psychological distress dropped from a moderately severe level down into the normal range, and nearly every single client improved. This is valuable because it's real-world NHS service data, not a lab study, though there was no control group and higher-quality larger studies are still needed.
CORE-10 scores improved from a mean of 20.16 (moderate-severe) at start to 8.71 (normal) at end (p<0.001), with statistically and clinically significant improvements across all measures except one client.

Thirty-nine trauma clients were treated by nationally recognized practitioners using one of four approaches, including Thought Field Therapy, in a side-by-side demonstration. All four approaches showed some immediate benefit that appeared to last. This methodology was designed to observe outcomes, not to formally test which treatment worked best, so read it as descriptive rather than comparative proof.
Across 39 participants, Traumatic Incident Reduction, Visual-Kinesthetic Dissociation, EMDR, and Thought Field Therapy each showed some immediate and lasting impact on clients.

Thirty-seven people in inpatient treatment for substance use disorder, all carrying trauma-related distress, did one Thought Field Therapy tapping session, and every single one of them reported a real drop in distress immediately afterward. That's a striking 100% response rate for a single brief session, though there was no comparison group and no follow-up reported, so it captures an immediate effect at one facility rather than lasting recovery outcomes.
In 37 participants at an inpatient addiction rehabilitation facility, a single Thought Field Therapy session was followed by a decrease in SUD ratings in 100% of participants; the group-level pre/post change was statistically significant (p<0.001).

Thirty-one refugees and immigrants, ages 5 to 48, who rarely seek traditional therapy for cultural and financial reasons, were treated with Thought Field Therapy and tested 30 days later. Every symptom category of PTSD dropped significantly. It's an uncontrolled study, but notable for reaching a population that typically goes untreated.
In 31 refugee/immigrant clients aged 5-48, pre-test to post-test (30 days later) scores showed a significant drop in all symptom subgroupings of PTSD criteria after Thought Field Therapy.

Ten female college athletes carrying distressing memories of past sports mistakes did a single 20-minute tapping session, and their distress ratings dropped while their confidence scores rose — and those gains were still holding two months later. Their pulse rate improvement was smaller and only bordered on statistically meaningful. With just 10 athletes and no comparison group, it's a small pilot suggesting a brief tapping session can shift how athletes carry a bad memory into competition.
In 10 female college athletes given a single 20-minute EFT session, significant post-intervention improvements were found in SUD, both emotional and physical CSIR distress, and sport confidence (p=.001), with gains maintained at 60-day follow-up; change in pulse rate was only marginally significant (p=.087).

Researchers interviewed Korean patients with Hwabyung — a condition from long-suppressed anger — after they went through a group tapping program, to understand their experience in their own words. Patients described feeling less overwhelmed by negative emotions, more able to hold onto positive feelings, and more like themselves again. Because this is a qualitative study without a comparison group or numeric outcome data, it speaks to lived experience rather than measurable symptom reduction.
Qualitative analysis found that group EFT therapy reduced the frequency and intensity of negative emotions and increased the frequency and duration of positive emotions in Hwabyung patients, with participants reporting restored self-image and improved stress-coping ability.

During five trips to war-torn Kosovo in 2000, international clinicians used Thought Field Therapy to treat 105 people carrying 249 separate traumatic memories. Nearly all of them, 103 out of 105 patients, reported total relief, and it held up at a five-month check-in with no relapses reported. There was no control group, so the dramatic numbers should be read as a field report rather than a controlled trial.

Eleven women living at a center for abused females went through EFT sessions, and the researchers used in-depth case study methods rather than test scores to understand what happened. Some participants developed better emotion regulation, while factors like family estrangement got in the way of progress for others. Because this is a qualitative case study rather than a trial with outcome numbers, it's better read for its practice insights than as proof of an effect size.
In a qualitative case study of 11 childhood sexual abuse survivors receiving EFT, emotion regulation skills improved for some participants, though family estrangement and other factors sometimes hindered progress.

Six women grieving a miscarriage went through individual EFT sessions to address both their anxiety and post-traumatic stress. Across the group, anxiety and trauma symptoms improved substantially and the gains held at follow-up. With just six participants and a single-case design, this is an early signal for a population, pregnancy loss, that badly needs more attention in the tapping literature.
Trait anxiety improved 38.75% in the treatment phase and 43.06% at follow-up; state anxiety improved 47.14% and 47.91% (as reported); PTSD symptoms improved 49.92% in treatment and 50.29% at follow-up.

This master's thesis interviewed three seasoned trauma therapists about what using energy psychology, including tapping, has done for their own practice and outlook, not about patient symptom scores. All three described the work as personally transformative, changing how they think about therapeutic change and even their own sense of contentment. With only three therapists interviewed, this is a small qualitative study about clinician experience rather than a test of patient outcomes.
Interviews with three experienced psychotherapists who use energy psychology for trauma treatment produced four themes: transformation, paradigm shift, state of presence, and spiritual realization, with therapists attributing significant changes in their professional and personal outlook to the practice.

A university student dealing with the psychological aftermath of dating violence went through an EFT counseling protocol tracked with a single-case study design — measuring wellbeing before, during, and after the tapping sessions. Wellbeing improved during the tapping phase. This is a single person's case study, not a trial with a comparison group, so it demonstrates a plausible individual counseling outcome rather than generalizable proof.
Using an A-B-A single-case design, EFT counseling was associated with improved psychological wellbeing in one dating-violence victim across baseline, intervention, and withdrawal phases.

A woman who suffered a bleeding stroke started daily tapping sessions within 24 hours of the event, and by the end of a week in hospital she was walking, balanced, and had far less pain, anxiety, and depression than typically expected — she was even driving again within weeks, and a later brain scan showed little trace of the damage. This is one dramatic single case, not a trial, so it can't tell us how often stroke patients would see results like this; it's best read as a striking clinical account rather than a predictor of typical recovery.
After roughly 90 minutes of daily EFT (supplemented with guided imagery) for seven days following a hemorrhagic stroke, the patient was discharged with reduced depression, anxiety, and pain, restored mobility and coordination, passed a driving test within weeks, and follow-up CT scans showed minimal residual scarring with stable blood pressure and no medication required.

One elite golfer struggling with the 'yips' — involuntary movements that wreck a golfer's stroke — went through four two-hour tapping sessions focused on a significant past event linked to when the yips started, and improved across every measure researchers tracked, including actual putting success on the course. Because this is a single-case study, it's a proof-of-concept suggesting tapping can help this specific performance condition, not evidence it will work the same way for others.
A single elite golfer with Type I 'yips' underwent four 2-hour EFT sessions targeting a significant life event linked to the condition, and showed improvements across all dependent measures — visual yips symptoms, putting success rate, and motion analysis — that transferred to competitive play.
