Table 3.

NTR versus Dutch population (2003-2017). Mean item scores (SD) and Pearson’s correlations (r) of social competence and behavioral control per SES variable category in unweighted sample.

	Dutch population	NTR	Δ	:	Social competence ¹	Behavioral control ²	r
Mother education (%)
Lower education	26.7	30.8	4.1	1.15	1.82 (0.21)^a	1.56 (0.38)^a	0.65
Middle education	44.3	35.0	−9.3	0.79	1.83 (0.20)^a	1.61 (0.35)^b	0.63
Higher education	29.0	34.2	5.2	1.18	1.85 (0.18)^b	1.67 (0.32)^c	0.61
Father education (%)
Lower education	23.6	31.8	8.2	1.35	1.82 (0.21)^a	1.57 (0.38)^a	0.65
Middle education	42.7	30.8	−11.9	0.72	1.83 (0.20)^a	1.61 (0.35)^b	0.63
Higher education	33.7	37.4	3.7	1.11	1.85 (0.19)^b	1.66 (0.32)^c	0.62

Parameters with different superscripts differ significantly from each other at the p < .05 level.

Δ = difference in percent points between NTR and Dutch population = NTR – Dutch population.

: = ratio of NTR to Dutch population = NTR ÷ Dutch population.
