Hierarchical Logistic Regression Analysis Predicting Suicide Attempt Status at Presentation to the Emergency Department (n=157)

Variable	b	SE	Wald Statistic	Odds ratio (95% confidence interval)
Step 1a
Any depressive disorder	1.35	0.58	5.55	3.87 (1.26–11.94)*
Prior suicide attempt
No prior attempt			9.63
One prior attempt	0.82	0.52	2.50	2.27 (0.82–6.27)
Multiple prior attempts	1.35	0.44	9.60	3.84 (1.64–9.01)*
Step 2b
IAT	1.85	0.94	3.93	6.38 (1.02–39.93)*

Notes: IAT = Implicit Association Test.

^aχ²(3, n=157) = 20.20, p < .01, R² = .18.

^bχ²(1, n=157) = 4.12, p < .05, R² = .21.

^*p < .05.
