Predictors	ESI-100 (β)	R2	Δ R2
Step 1 (entered together)		.61**	--

Step 2 (entered individually)

PSB	−.25**	--	.04**
CSN	−.13**	--	.01**
COP	−.05†	--	<.01†

Note. N = 756–757; ESI-100 = Externalizing Spectrum Inventory, 100-item screening version. PRI = Personal Reliability Index; SWB = Sense of Well-being, PSB = Prosocial Background, CSN = Compliance with Social Norms, COP = Conventional Occupational Preferences. Step 1 = MPQ primary scale scores entered together as predictors of ESI-100 scores. Step 2 = PRB scale scores entered individually as predictors of ESI-100 scores after controlling for MPQ scores in Step 1.
