Although most cigarette smokers want to quit, only 5% succeed in doing so each year. One reason for this low success rate is that smoking-related cues stimulate strong urges to smoke. Cues include observing someone else smoking, or engaging in activities previously associated with smoking (e.g., work breaks, meals, a cup of coffee, sex). Finding ways to reduce cue-induced urges may help more people quit.
Research shows that a brain area called the posterior cingulate cortex (PCC) becomes activated whenever cigarette smokers are exposed to smoking-related cues. Research also indicates that mindfulness meditation as an intervention reduces PCC activity. Janes et al. [Neuropsychopharmacology] tested whether a smartphone mindfulness app reduced smokers’ PCC reactivity to smoking-related cues and their smoking behavior.
The researchers recruited 83 adult smokers who were interested in quitting, 67 of whom completed the study and were included in the final data analysis (average age = 44; 67% female; 91% Caucasian). PCC-reactivity to smoking cues was assessed by functional magnetic resonance imaging (fMRI) and participants were then randomly assigned to either mindfulness training or a control condition. Both conditions used smartphone apps for 4 weeks to help quit smoking. Participants’ PCC reactivity to smoking-related cues was re-assessed via fMRI after the intervention.
The mindfulness app consisted of 22 modules that offered daily training videos and on-demand exercises to teach the core elements of mindfulness. The app also helped participants identity triggers, monitor smoking habits, increase awareness of urges, and use mindfulness as a coping mechanism.
The control group used the National Cancer Institute’s QuitGuide App to help monitor motivation and triggers, as well as offer inspirational messages and tips for dealing with cravings and […]
