We published a meta-analysis of studies that examined the various components of an evidence-based therapy called emotional freedom techniques (EFTs). EFT uses elements of conventional therapies such ...as exposure and cognitive processing but includes the unique ingredient of acupoint stimulation using fingertip tapping. Six studies were identified, and three of these met the quality control criteria of the American Psychological Association's Division 12 Task Force for Empirically Validated Therapies. Meta-analysis found that the acupoint component of EFT was not an inert ingredient or inactive placebo but made an active contribution to the therapeutic effects noted in a research literature that now numbers over 100 clinical trials of EFT. Subsequent to publication, errors in the original analysis were identified, primarily incorrect standard deviations. A new analysis was performed by an independent statistician and found slightly greater effects than the original investigation. The results were published as a corrigendum, which was subsequently challenged by Spielmans. Here we examine the critiques of the corrigendum and original article. We find that although they may be of academic interest, they are irrelevant to the central research question of whether the acupoint component of EFT is inert or active. We reaffirm that the evidence clearly validates the contribution made by acupoint tapping to EFT's observed clinical effects.
In a prior article (Spielmans, Rosen, Spence-Sing J Nerv Ment Dis 208:628-631, 2020), we demonstrated that Church, Stapleton, Yang, and Gallo's (J Nerv Ment Dis 206:783-793, 2018) meta-analytic ...finding that acupoint tapping had specific therapeutic benefit was highly flawed, both statistically and methodologically. Our analysis based on corrected effect sizes found no significant benefit for acupoint tapping at study endpoint. Church, Stapleton, Kip, and Gallo (J Nerv Ment Dis 208:632-635, 2020) issued a corrigendum in which they reported a new post hoc analysis using follow-up (rather than study endpoint) measures. Shifting to a post hoc outcome while pooling highly disparate follow-up endpoints is problematic; it ignored the nonsignificant result of the a priori analysis. Here, we clarify these issues and address Church, Stapleton, Kip, and Gallo's (J Nerv Ment Dis 208:632-635, 2020) often irrelevant or confusing responses to our methodological concerns. Considering this recent exchange of articles, and absent meaningful correction to the original incorrect findings, we remain concerned that emotional freedom technique proponents will continue to advance unfounded claims regarding the purported benefits of acupoint tapping.
•Bifocal emotion regulation successfully mitigates aversive reactions to phobic stimuli.•Acupoint tapping increases amygdala activation and decreases hippocampus activation.•Responses to phobia and ...fear differ during picture viewing but not acupoint tapping.•A one-time bifocal-multisensory intervention decreases measures of fear of flying.•Fewer individuals meet the criteria for fear of flying after the intervention.
Very few studies have investigated the neural underpinnings of bifocal-multisensory interventions such as acupoint tapping (tapping) despite their well-documented efficacy. The present study aims to investigate the neural and behavioral responses to tapping during the perception of phobic and generally fear-inducing stimulation in a group of participants with fear of flying. We studied 29 flight-phobic participants who were exposed to phobia-related, fear-inducing and neutral stimulation while undergoing fMRI and a bifocal-multisensory intervention session consisting of tapping plus cognitive restructuring in a within-subject design. During tapping we found an up-regulation of neural activation in the amygdala, and a down-regulation in the hippocampus and temporal pole. These effects were different from automatic emotion regulatory processes which entailed down-regulation in the amygdala, hippocampus, and temporal pole. Mean scores (±SD) on the Fear of Flying scale dropped from 2.51(±0.65) before the intervention to 1.27(±0.68) after the intervention (p <.001). The proportion of participants meeting the criteria for fear of flying also dropped from 89.7 percent before the intervention to 24.0 percent after the intervention (p <.001). Taken together, our results lend support to the effectiveness of tapping as a means of emotion regulation across multiple contexts and add to previous findings of increased amygdala activation during tapping, as opposed to amygdala down-regulation found in other emotion regulation techniques. They expand on previous knowledge by suggesting that tapping might modulate the processing of complex visual scene representations and their binding with visceral emotional reponses, reflected by the down-regulation of activation in the hippocampus and temporal pole. Bifocal emotion regulation was useful in ameliorating aversive reactions to phobic stimuli in people with fear of flying.
