Ordinal logistic regression model.

	Parameter	B (SE)	OR	p
Threshold	Early dropout to partial completion	−0.16 (0.77)
	Partial to successful completion	1.50 (0.79)
Prior addiction rehab	No (vs. yes)	0.92 (0.45)	2.52	0.039*
Current substance use comorbidity		−1.14 (0.45)	0.32	0.012*
Current depressive disorder		1.58 (0.78)	4.87	0.041*

This model was built from a base model by progressively removing the non-significant variables (first to last: current personality disorder, sex, expecting parents, current attention-deficit hyperactivity disorder, age). N = 84 with complete data on all variables. ${\text{X}}_{(3)}^2$ = 11.452, p = 0.010, Nagelkerke pseudo R² = 14.6%.
