SMART Design Used by Stanger and colleagues (2019)

Adaptive Intervention	$A_1$	$A_2$	Stage 1	Response Status	Stage 2	Cells (Fig. 1)
Enhanced working memory training	1	1	WMT+CM	Responder	Continue	D,E
				Nonresponder	Add EI
Working memory training alone	1	−1	WMT+CM	Responder	Continue	D,F
				Nonresponder	Continue
Enhanced incentives alone	−1	1	CM	Responder	Continue	A,B
				Nonresponder	Add EI
Standard contingency management	−1	−1	CM	Responder	Continue	A,C
				Nonresponder	Continue

Note: WMT = working memory training, CM = contingency management, EI = enhanced incentives.
