Subclaims¶

q3 i3 The experimental group's pre-to-post reduction in compression rate deviation substantially exceeded the control group's change (Cohen's d = −1.52), and gains transferred to an unscaffolded one-minute post-test. → Yibo Meng 2026

q3 · i3 · causal · r2

Randomised controlled study (T1 pre-test, T2 10-minute intervention, T3 post-test) with 40 lay community members in Tibet; experimental n=20, control n=20. The between-group change-score contrast gave "Cohen's𝑑=− 1.52"; an ANCOVA controlling for T1 mirrored it (F(1,37)=54.64, partial η²=.596).

"A direct between-group comparison of the change scores ( Δ=𝑇 3−𝑇 1) confirmed that the experimental gain substantially exceeded any change observed in control,𝑡( 38)=− 4.80,𝑝<. 001, Cohen's𝑑=− 1.52"

Discussion¶

Related Claims¶

• In one experiment with 256 undergraduates, computer-based lesson versions that included practice produced significantly higher posttest scores than versions without practice — the general claim this finding bears on, with the studies behind it
• TibetCPR training produced depth-accuracy gains that substantially exceeded unguided practice and transferred to an unscaffolded post-test — related
• Depth accuracy rose progressively during the intervention, with the experimental group improving roughly three percentage points per minute faster than the control group — related
• Experimental-group participants rated TibetCPR highly usable (SUS = 84.3, an Excellent rating), with the highest items on voluntary engagement and independent use — related
