Experimental studies of the impact of mindfulness on stress reactivity

Study	SUD/addictive behavior (sample size)	MBI	Control condition	Results
Carroll & Lustyk113	Polysubstance use (N=34)	MBRP: 8 weekly, 2-hour group sessions	Relapse prevention: 8 weekly, 2-hour group sessions TAU	Participation in MBRP was associated with higher cardiac vagal control and lower stress/anxious reactivity.
Kober et al114	Tobacco use disorder (N=23)	Mindfulness training	Freedom from Smoking	Participants in mindfulness training demonstrated lower stress-reactivity compared to the control group.
Paz et al115	Tobacco use disorder (N=104)	Present moment attention and awareness training	Cope-as-usual control condition	Present moment attention and awareness training was associated with reductions in psycho-physiological dysregulation in response to an axiogenic stressor.

Abbreviations: SUD, substance use disorder; MBI, mindfulness-based interventions; MBRP, mindfulness-based relapse prevention; TAU, treatment-as-usual.
