Hierarchical Logistic Regression testing main effects of affect; attentional control; and BPD features on prior incidence of self-harm.

	R2	Odds ratio	95% CI
	$R_a^2-R_b^2$		Lower–Upper
Step 1	0.06–0.08
Negative affect		1.05*	1.02–1.07
Positive affect		0.97*	0.94–0.99
Step 2	0.22–0.31
Negative affect		0.94*	0.91–0.98
Positive affect		1.01	0.98–1.04
BPD		5.99**	3.64–9.88
Step 3	0.34–0.47
Negative affect		0.94*	0.90–0.99
Positive affect		1.02	0.99–1.06
BPD		7.51**	4.26–13.25
Focusing		1.20**	1.11–1.30
Shifting		0.66**	0.58–0.75
Flexibility		1.04	0.93–1.18

Note: $R_a^2$ = Cox and Snell, $R_b^2$ = Nagelkerke, * p < 0.05; ** p < 0.001.
