Trial of EFT in overweight/obese adults — depression outcome (as tabulated in Nelms & Castel 2016)

Stapleton, P., et al. · 2013

Randomized trial👥 45 participants⚖️ vs. waitlist📈 Cohen's 0.37 (small)Moderate rigor📍 Australia
In plain English. In this weight-related tapping trial, depression symptoms improved modestly more in the tapping group than in the waitlist group, a smaller effect than seen in many of the other studies in this body of research.

Depression symptoms decreased by 21% (d=0.37) in this sample; the same study's anxiety outcome (analyzed N=96) is recorded separately with d=0.27.

💡 Where this could help

Think of someone whose weight struggles and low mood feed into each other in a discouraging loop. If this modest effect strengthens with more research, tapping — learnable on one's own and free to keep practicing — could become one small piece of a broader plan for people managing depression tied to body image and weight, not a stand-alone fix, but a genuine option worth having.

🔬 What to study next

Weight struggles and low mood can feed into each other through a shared stress-eating cycle, so the interesting next step is testing whether this modest depression benefit tracks objective markers implicated in that cycle — cortisol, insulin or leptin, or inflammatory markers linked to both obesity and depression. It would also be worth testing whether combining tapping with existing weight-management or nutrition programs produces a bigger combined effect than either approach alone.

Verification note. Could not identify a primary paper with N=45 matching this record. The two closest known Stapleton overweight/food-craving trials remain: (1) Stapleton et al. 2013, ISRN Obesity/'Depression symptoms improve after successful weight loss with EFT' -- N=96 randomized (4-week EFT vs waitlist, 12-month follow-up), and (2) Stapleton, Devine, Chatwin, Porter & Sheldon (2014), Current Research in Psychology 5(1):19-33, a feasibility study of EFT for Major Depressive Disorder in a general (not specifically overweight) adult population, 8-week group treatment. Neither matches N=45 or is confirmed as the source of d=0.37. This record's own citation is explicitly the Nelms & Castel 2016 secondary table (also referenced in the anxiety-outcome note, N=96), so the number is traceable to a named source even though the underlying primary paper could not be independently pinned down this pass. Left unchanged per the no-invention rule; status remains partial.
