Self-regulation of learning – Means and standard errors (SE) for work effort score at age 3 and for difference between age 3 and age 5, by sex of child and household income level
	Mean score age 3	Standard error (SE)	Difference age 3 to age 5	Standard error (SE)
	Work effort score
Total (n=3,711)	3.9	0.03	+0.31	0.03

Female	4.0	0.04	+0.34	0.05
Male	3.8	0.04	+0.28	0.05
Household income level
Below low income cut-off (LICO) (level 1)	3.6¹	0.08	+0.45	0.10
LICO to less than 2 times LICO (level 2)	3.9	0.04	+0.23	0.06
Two times LICO to less than 3 times LICO (level 3)	4.0	0.06	+0.34	0.07

1. Statistically significant and substantive difference between level 1 and level 3.
Notes Statistical significance: p<0.008 for differences among 4 levels of household income level (nominal significance level of p<0.05 adjusted for multiple comparisons). Substantive differences are defined as mean differences of 0.25 of a standard deviation (0.25 SD) or more, as follows: for work effort score at age 3, 0.25 SD=0.33; for difference score age 3 to age 5, 0.25 SD=0.40. LICO refers to the low income cut-off.
