Outcome Measures

Primary Outcomes (8)

  • Change in nicotine consumption from pre-intervention to post-intervention

    self-report

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in nicotine consumption from pre-intervention to follow-up

    self-report

    Pre-intervention and follow-up (12 weeks after intervention end)

  • Change in BOLD during cue reactivity task (fMRI) from pre-intervention to post-intervention

    Blood Oxygen Level Dependent especially within the ventral striatum, the ventral medial prefrontal cortex and the amygdala during a cue reactivity task with neutral, tobacco, alternative reward images and warning images depicting aversive consequences of smoking

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in BOLD during down-regulation of craving task (fMRI) from pre-intervention to post-intervention

    Blood Oxygen Level Dependent especially within the ventral striatum, the amygdala and the dorsolateral prefrontal cortex during a cognitive down-regulation of craving task with tobacco and alternative reward stimuli

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in BOLD during stop-signal task (fMRI) from pre-intervention to post-intervention

    Blood Oxygen Level Dependent especially within the dorsolateral prefrontal cortex during a stop signal task

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in craving ratings (behavioral) from pre-intervention to post-intervention

    The participants' answers to the question "how strong is your desire to consume the item shown" on a scale of 1 - 8 is averaged over a total of 144 pictures of nicotine and alternative reward stimuli. The change in average ratings between pre-intervention and post-intervention is computed.

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in down-regulation of craving (behavioral) from pre-intervention to post-intervention

    The down-regulation of craving task is carried out as described in Kober et al., 2010. As described there, the down-regulation of craving is calculated as the difference in craving ratings between the now and later condition (20 nicotine and alternative reward stimuli are shown in the now and later condition). The change in the down-regulation of craving between pre- and post-intervention is then calculated.

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

  • Change in stop-signal reaction time (behavioral) from pre-intervention to post-intervention

    Stop-signal reaction time in the stop-signal task

    Pre-intervention and post-intervention (up to 2 weeks after intervention end)

Behavioral: Exercise trainingBehavioral: Smoking cessation group program

Smoking cessation group program

ACTIVE COMPARATOR
Behavioral: Smoking cessation group program

Interventions

The moderate-intense aerobic exercise training will involve supervised aerobicycle ergometer training for 30 min with 60-80% HRmax three times per week for 12 weeks.

Exercise training plus smoking cessation group program

Participants of both groups will receive a 6-week standard cognitive behavioral therapy-oriented smoking cessation group program (SCP, one 60 min session per week).
