	Boys	Girls		Boys	Girls	Boys	Girls
Ideation	Fixed	1.249^***	4.785^***	.265^***	−.008^ns	−.019^ns	−.165^***	τ₁ = 2.601^*** (.184)
	at 0	(.216)	(.600)	(.043)	(.040)	(.023)	(.024)	τ₂ = 4.217^*** (.216)
Plans	Fixed	.976 ^***	6.991^***	.186^***	−.021^ns	−.041^ns	−.211^***	τ₁ = 4.390^*** (.308)
	at 0	(.297)	(1.109)	(.048)	(.053)	(.033)	(.038)	τ₂ = 6.149^*** (.364)
Attempts	Fixed	1.029^**	5.700^***	.131^**	.018^ns	−.121^***	−.116^**	τ₁ = 5.628^*** (.512)

Note: Coefficients are the unstandardized logits; SE = standard error; τ = threshold. Age was centered at 16. All models controlled for family structure.
