Brief Summary

Cognitive-behavioral therapy (CBT) combined with medication is an established intervention for smoking cessation. However, long-term abstinence rates of maximum 35% are yielded. Moreover, acceptance of drug treatment is partly very low. Professional recommendation of drug treatment besides nicotine-replacement aids is restrained considering side effects and contraindications. Currently, cue exposure is highly discussed as intervention for craving reduction supporting CBT. There is evidence for benefits of cue exposure optimizing smoking cessation outcomes, as well as evidence for efficacy of exposure in virtual reality (VR) up to date. However, this is the first randomized controlled study focusing on efficacy increases by VR cue exposure supporting an established CBT smoking cessation manual. The control group receives a specific stress reduction treatment (independent of smoking cues), namely, the Progressive Muscle Relaxation (PMR, according to Jacobson) additionally to the established smoking cessation CBT.

Outcome Measures

Primary Outcomes (1)

  • Continuous (self-reported) abstinence rates from smoking 6 months after end of treatment

    6-month continuous smoking abstinence according to the Russell Standard (West et al., 2005): no cigarette smoking assessed by self-report (number of smoked cigarettes) and a negative biochemical validation (CO measurement below 9) at the final follow-up. 6-month continuous smoking abstinence ordinal scale: 0=no abstinence, 1= either subjective or biochemical validation depicts no abstinence, 2= biochemical validated abstinence at the 6 months follow-up.

    at the 6 month follow-up

Secondary Outcomes (8)

  • Changes in smoking cue event-related potentials (ERP: LPP)

    Differences from baseline to the 6 month follow-up

  • Changes in smoking cue event-related potentials (ERP:P3)

    Differences from baseline to the 6 month follow-up

  • Changes in approach tendency to smoking pictures

    Differences from baseline to the 6 month follow-up

  • Changes in smoking cue reactivity related skin conductance level

    Differences from baseline to the 6 month follow-up

  • Changes in Theta and Alpha band power during smoking cue exposure

    Differences from baseline to the 6 month follow-up

  • +3 more secondary outcomes
