Interaction: Area and Private Insurance*			<.001

^*Post-hoc pairwise comparisons were limited to urban and suburban practices as there were only n=3 pediatricians who worked in rural areas and reported ≥80% of patients had private insurance, and none of them reported on-site child/adolescent MH providers
