Difference in pretest-posttest measures directly after completing a session with the app.^a

Outcome measure	Experiment 1—single sessions				Experiment 2—repeated measures
	Effect size	Magnitude	P value	Effect size		Magnitude	P value
Intensity of the emotion	−0.87	Large	<.001	−0.67		Large	<.001
Strength of the struggle	−0.83	Large	<.001	−0.66		Large	<.001
Strength of maladaptive belief	−0.82	Large	<.001	−0.60		Large	<.001
Strength of adaptive belief	0.27	Small	<.001	0.28		Small	<.001
Likelihood of unwanted action	−0.79	Large	<.001	—b		—	—
Likelihood of valued action	0.68	Large	<.001	—		—	—

^aThe common interpretation for effect size values for paired Wilcoxon tests in published literature is small effect (0.10 to <0.3), moderate effect (0.30 to <0.5), and large effect (≥0.5) [33].

^bIn experiment 2, pretest-posttest changes in participants likelihood of unwanted and valued action were not measured.
