Meta-analysis Higher rigor
Zheng, D., Lin, X., Gao, X. et al. · 2025
This review pooled results from 10 separate studies of tapping in cancer patients, covering 774 people total. Combined, the evidence shows tapping meaningfully eases depression, anxiety, and sleep problems in people with cancer. For the harder-to-treat experience of anticipatory grief — fear and sadness about the future — tapping helped with some pieces (like sadness, anger, and feeling supported) but not others (like adjusting to the disease or overall psychological distress), which the researchers are honest about rather than glossing over.
Pooling 10 RCTs (774 patients: 388 EFT, 386 control), EFT significantly reduced depression (MD=-7.41, 95% CI -9.32 to -5.51, p<.001) and anxiety (MD=-7.92, 95% CI -11.01 to -4.83, p<.001) and improved sleep quality (MD=-1.96, 95% CI -2.80 to -1.13, p<.001); for anticipatory grief, EFT improved sadness, anger, death attitude, somatic symptoms, religious comfort, and perceived social support, but showed no significant effect on disease adjustment, self-awareness, or psychological distress.
Systematic review Preliminary
Hasibuan, S.H., Said, F.M., Rashid, N.A. et al. · 2025
Researchers reviewed published studies on tapping (EFT) and its spiritual variant (SEFT) for breast cancer patients' mental health. Across the studies they found, both approaches reduced stress, anxiety, and depression, with the spiritual version potentially helping elderly patients more. As a literature review rather than new data collection, its conclusions are only as strong as the underlying studies, many of which are small and uncontrolled.
A systematic literature review of PubMed and Google Scholar articles (2019-2024) found EFT and SEFT effective for reducing stress, anxiety, and depression in breast cancer patients, with SEFT's spiritual component offering additional benefit especially for elderly patients.

SEFT (related method)
Hamidah, H., Rauf, S., Arifuddin, S. et al. · 2024
This review pulled together studies on spiritual tapping (SEFT) for cervical cancer patients who'd finished chemoradiation and concluded it helps with pain, stress, and depression. As a narrative review of small studies rather than new controlled data, the conclusions are only as reliable as the underlying (mostly small) studies it summarizes.
A systematic review of studies from 2003-2023 found SEFT beneficial for lowering pain, stress, and depression among post-chemoradiation cervical cancer patients.
Randomized trial Higher rigor
Tack, L., Lefebvre, T., Lycke, M. et al. · 2021
121 cancer survivors dealing with "chemo brain" — foggy thinking and memory problems after treatment — either started tapping right away or were put on an 8-week waiting list first. After 8 weeks, most of the waiting group still had cognitive complaints (87%), while far fewer of the tapping group did (41%) — and once the waiting group got their turn to tap, they caught up to the same improvement. Distress, depression, tiredness, and quality of life all improved too. This is one of the largest and best-designed tapping trials in cancer survivors to date.
121 cancer survivors with self-reported cognitive impairment (CFQ≥43) were randomized to immediate EFT treatment or an 8-week wait-list; at 8 weeks, 40.8% of the immediate-treatment group still screened positive for cognitive impairment versus 87.3% of the wait-list group (p<0.01), and the wait-list group caught up to a similar level of improvement after their own 8 weeks of EFT; distress, depressive symptoms, fatigue, and quality of life also improved significantly.
Randomized trial Moderate rigor
Kaplan, M., Çelik, H. · 2025
Seventy people being treated for cancer were split into a group that got four half-hour tapping sessions over two weeks and a group that received usual hospital care. The tapping group's pain ratings dropped by roughly half and their depression scores dropped by more than a third, while the usual-care group barely improved on pain and actually got slightly more depressed over the same two weeks. It's a single-hospital study, so it's a strong early result that would benefit from replication elsewhere.
70 cancer patients were randomized to 4 EFT sessions over two weeks (n=35) or routine care (n=35); pain (VAS) fell from 4.82 to 2.44 in the EFT group versus 5.36 to 4.25 in controls (EFT p<0.05, control not significant), and depression (BDI) fell from 31.44 to 18.44 in the EFT group while it rose slightly in controls (27.94 to 31.42).
Randomized trial Moderate rigor Critical finding
Lazarov, A., Church, D., Shidlo, N. et al. · 2025
Fifty-three melanoma survivors — people who'd finished treatment at least six months earlier — were split into three groups: tapping together in a group, tapping one-on-one with an instructor, or a waiting list. Both tapping formats helped people feel calmer during sessions and better understand how to reduce their cancer-recurrence risk, and over 80% said they were satisfied with real, positive changes. However, on measures like ongoing fear of the cancer coming back, the tapping groups didn't significantly outperform the waiting list — an honest result worth noting. Group tapping worked about as well as one-on-one sessions, which matters for making it more accessible and affordable.
53 melanoma survivors were randomized to Group EFT (n=16), Individual EFT (n=18), or a waiting-list control (n=19), with weekly sessions for 4 weeks; both EFT formats significantly improved participants' understanding of how to prevent recurrence and spiritual wellbeing, and produced significant decreases in within-session distress (SUDs), though fear of recurrence and general affect did not significantly differ from control; over 80% of EFT participants reported positive changes and satisfaction, with group and individual formats performing similarly.
Controlled trial Moderate rigor
Kalroozi, F., et al. · 2022
Women recovering from breast cancer surgery — some from military families, some not — were taught tapping and compared against similar women who didn't receive it. In both groups, the women who learned tapping slept better and reported more happiness right after and a month later, and it worked equally well regardless of military-family background. This was a quasi-experimental study, meaning participants weren't randomly assigned, so it carries a bit more risk of hidden differences between groups than a full RCT.
Sleep quality and happiness scores improved significantly immediately after and one month after the EFT intervention in both military and nonmilitary intervention groups compared to their respective control groups, with no significant difference between the military and nonmilitary intervention groups.
Controlled trial Moderate rigor
SEFT (related method)
Desmaniarti, Z., Avianti, N. · 2017
This is the Indonesian SEFT variant, which combines tapping with prayer and spiritual surrender rather than the standard secular EFT protocol. 68 women with cervical cancer going through chemotherapy in Indonesia were split into a SEFT group and a no-treatment group. The women who did three short SEFT sessions reported feeling less stressed than those who didn't. It's described using language suggestive of randomization, but the exact allocation method wasn't detailed, so it's treated cautiously here as a controlled (not confirmed randomized) trial.
After three 30-minute SEFT sessions, patients' stress scores were significantly lower than the control group, per the study's paired and independent t-test analysis.
Controlled trial Moderate rigor
Zheng, D., Xiao, W., Duan, D. et al. · 2025
Fifty-eight people being treated for cancer — many grappling with the fear and sadness of an uncertain future, on top of anxiety and poor sleep — either added four weeks of short guided tapping sessions to their usual care or just continued usual care. The tapping group felt less anticipatory grief, less anxious, and slept better than the comparison group by the end of the month. It's a fairly small trial from a single research group, so a larger follow-up would help confirm the size of the benefit.
58 cancer patients were allocated by ward (not individually randomized, though the paper labels itself an RCT) to 4 weeks of EFT plus routine care (n=30) or routine care alone (n=28); the EFT group had significantly lower anticipatory grief (p<.01), greater anxiety reduction (p=.04), and improved sleep quality (p<.01) after 4 weeks.
Controlled trial Preliminary Indonesian
Ningsih, S., Karim, D., Sabrian, F. · 2015
Thirty women with stage II or III breast cancer in Indonesia tried EFT to help with the anxiety that comes with a serious cancer diagnosis. Those who did EFT saw a significant drop in anxiety compared to a similar group that didn't. It's a modest-sized quasi-experimental study, so a fully randomized trial would strengthen the evidence.
The experimental group showed a significant reduction in anxiety (p = 0.005) compared to the non-equivalent control group.
Outcome study Preliminary
Mohamed, A.F., Hamed, A.E.M., Mohamed, S.S.A. · 2025
Mastectomy patients in Egypt did six weeks of EFT sessions and reported large drops in stress along with large gains in resilience and sexual satisfaction. The effect sizes reported are unusually large, which is common in single-group pre/post designs without a comparison group to rule out other explanations like time passing or extra nursing attention.
Perceived stress dropped from 32.42 to 17.27, resilience rose from 11.53 to 31.46, and sexual satisfaction rose from 17.03 to 31.00 after six EFT sessions (all p < 0.001), with strong correlations between stress, resilience, and sexual satisfaction.

Women struggling with the mood and physical side effects of hormone therapy for breast cancer did a 3-week EFT course, then kept practicing on their own. Their mood, anxiety, depression, and fatigue scores all improved, holding up through 12 weeks. This was a service evaluation without a control group, so some of the improvement could reflect other factors like time or extra clinical attention.
Statistically significant improvements in Total Mood Disturbance (p=0.005/0.008), anxiety (p=0.003/0.028), depression (p=0.006/0.020), and fatigue (p=0.008/0.033) occurred at both 6 and 12 weeks compared to baseline; hot flush frequency also decreased.

Hamidah, H., Rauf, S., Arifuddin, S. et al. · 2025
Cervical cancer patients undergoing chemoradiation practiced Spiritual EFT and had their pain, stress hormone (cortisol), and an inflammation marker (IL-6) measured before and after. All three dropped substantially. Because this was a one-group pre/post design with no control group, some of the change could reflect the chemoradiation treatment itself rather than SEFT alone.
Average pain severity fell from 4.5 to 1.6, cortisol from 632.9 to 305.3, and IL-6 from 260.1 to 106.7 after SEFT (p < 0.001 for cortisol; significant correlations between pain, cortisol, and IL-6, p<0.001).

Hasal, D. M., Muriyati, Alfira, N. · 2021
Fifteen cancer patients at an Indonesian clinic tried a spiritually-oriented form of EFT for their anxiety about the disease. Afterward, the share reporting only mild anxiety jumped to over 93%, a statistically significant shift. It's a very small, uncontrolled single-group study, so it should be read as an early signal.
The proportion of respondents with average anxiety fell and lightweight/mild anxiety rose to 93.3% after SEFT therapy, with a Wilcoxon test showing a significant effect (p = 0.002).
Case series Preliminary

Sukesi, N., Wahyuningsih, W., Prasetyorini, H. · 2020
This is a very small case study — just four cancer patients in Indonesia — looking at whether SEFT (the Indonesian spiritual variant of tapping, which includes Islamic prayer) helped with pain. The researchers described the patients as experiencing less pain afterward, based on interviews rather than a formal before-and-after measurement with a statistical test. With only four people and no comparison group, this counts as a very early, exploratory observation rather than solid evidence.
In this four-patient case series, SEFT was described as having a meaningful influence in reducing cancer pain, based on qualitative interview and observation data rather than a formal statistical test.
Case series Preliminary
TFT (related method)
Callahan, J. · 2004
A single case report describes a woman with advanced lymphoma who used Thought Field Therapy alongside her medical cancer treatment and was cancer-free 18 months later. As a single case study, this cannot show that TFT contributed to the cancer outcome versus the medical treatment itself.
A patient treated with TFT alongside medical cancer treatment to address trauma, anxiety, and medication side effects was reported cancer-free after a year and a half.
