PCIR summary statistics overall for pre- and postassessment Construct mean (M) ± standard error of the mean (SEM)^a

N = 797	Construct mean (M ± SEM)		Kendell’s W	Paired t test
	Pre	Post	Effect size	t(796)	p value
Recognition score	3.13 ± 0.035	3.25 ± 0.035	0.038 (small)	−4.9	1.4e-06
Interest score	4.14 ± 0.029	4.12 ± 0.030	N/A	0.83	0.41
Performance/competence score	3.76 ± 0.026	3.84 ± 0.025	0.014 (small)	−4.2	2.6e-05

^aBold values indicate significant shifts using the two-tailed paired t test. Italics indicate mean values that decreased from pre to post. For three comparisons, Bonferroni's adjustment for significance is p < 0.0167.
