Abstract EN
The primary goal of this pilot feasibility study was to examine the effects of Mindfulness-Oriented Recovery Enhancement (MORE), a behavioral treatment grounded in dual-process models derived from cognitive science, on frontostriatal reward processes among cigarette smokers.
Healthy adult (N=13; mean (SD) age 49 ± 12.2) smokers provided informed consent to participate in a 10-week study testing MORE versus a comparison group (CG).
All participants underwent two fMRI scans: pre-tx and after 8-weeks of MORE.
Emotion regulation (ER), smoking cue reactivity (CR), and resting-state functional connectivity (rsFC) were assessed at each fMRI visit; smoking and mood were assessed throughout.
As compared to the CG, MORE significantly reduced smoking (d=2.06) and increased positive affect (d=2.02).
MORE participants evidenced decreased CR-BOLD response in ventral striatum (VS; d=1.57) and ventral prefrontal cortex (vPFC; d=1.7) and increased positive ER-BOLD in VS (dVS=2.13) and vPFC (dvmPFC=2.66).
Importantly, ER was correlated with smoking reduction (r’s = .68 to .91) and increased positive affect (r’s = .52 to .61).
These findings provide preliminary evidence that MORE may facilitate the restructuring of reward processes and play a role in treating the pathophysiology of nicotine addiction.
