Prediction rules for best performing models

	Complex model (Table 2, Model 4)		Individual model (Table 1, Model 5)
	AUC = 0.91		AUC = 0.80
Quantity (χ)	Estimate ($\hat{\beta }$)	SE	Estimate ($\hat{\beta }$)	SE
Intercept	19.90	11.74	2.59	2.05
Mean Hopelessness	−3.19	2.24
Variance Hopelessness	−2.87	7.89
Mean Self-Efficacy	−2.06	1.11	−0.60	0.30
Variance Self-Efficacy	−0.18	0.72
Mean Duration of Suicidal Ideation	2.15	1.16
Variance Duration of Suicidal Ideation	−1.54	2.12
Prediction Rules	IF $\frac{e^{X\widehat{\beta }}}{1+e{}^{X\hat{\beta }}}\ge 0.462$ THEN   Flag person as at-risk of suicidal crisis.		IF $\frac{e{}^{X\hat{\beta }}}{1+e{}^{X\hat{\beta }}}\ge 0.197$THEN   Flag person as at-risk of suicidal crisis. Equivalently, IF Mean self efficacy ≤ 6.66 THEN   Flag person as at-risk of suicidal crisis.

Note. AUC = Area Under the Receiver Operating Characteristic Curve. χ is a design matrix having number of rows equal to the number of study participants. For Table 2, Model 4 the columns of χ have values corresponding to 1’s, mean hopelessness, variance hopelessness, mean self-efficacy, variance of self-efficacy, mean duration of suicidal ideation, and variance of duration of suicidal ideation. For Table 1, Model 5 the columns of χ have values corresponding to 1’s, and mean self-efficacy.
