Reduced number of cigarettes smoked[ Time Frame: First assessment on Day 1, second on Day 8 ]
Smoking habits will be assessed via interview at the beginning of the study and after a follow-up period of three days. Number of cigarettes smoked will be compared longitudinally and between groups.

  • Reduced Carving[ Time Frame: First assessment on Day 1, second on Day 5, third on Day 8 ]
    Craving will be assessed using visual analog scales on the first and fifth day of the study as well as in the follow-up interview. Ratings will be compared longitudinally and between groups..
  • Increased inhibitory control[ Time Frame: First and second testing on Day 1, third testing on Day 5 ]
    Inhibitory control will be assessed in neuropsychological tests (Go / No-Go, Stop-Signal Task) before and after the first stimulation session and after the fifth session. Results will be compared longitudinally and between groups.
 
Transcranial Direct Current Stimulation - Tobacco Use Disorder
Transcranial Direct Current Stimulation as an Intervention in Tobacco Use Disorder: Effects on Consumption and Craving

This study aims to detect how transcranial direct current stimulation (tDCS) affects smokers' inhibitory control, craving and consumption of tobacco goods.

Participating smokers are to receive anodal transcranial direct current stimulation of the right dorsolateral prefrontal cortex (rDLPFC) for 20 minutes on five consecutive days. Neuropsychological tests on inhibitory control and interviews on smoking habits and craving will be applied before and after the first stimulation as well as after the fifth stimulation. After a follow-up period of three days, smoking behaviour will be assessed in a telephone interview. Changes in inhibitory control and smoking behaviour will be compared between an active and a sham stimulation group.This way the effects of transcranial direct current stimulation on tobacco use disorder are to be clarified.

N/A
分配: Randomized
干预模型: Parallel Assignment
干预模型描述: Half of the participants will receive transcranial direct current stimulation, while the others will receive sham stimulation.
盲法: Interventional
盲法描述:Participants will be blinded as to their assigned study arm.
主要目的: Treatment
  • Device: tDCS
    The participants will receive anodal tDCS (transcranial direct current stimulation) of the right dorsolateral prefrontal cortex for 20 minutes on five consecutive days.
  • Device: Sham tDCS
    The participants will receive sham tDCS (transcranial direct current stimulation) of the dorsolateral prefrontal cortex for 20 minutes on five consecutive days.
  • Active Comparator: anodal tDCS over rDLPFC
    Participants will receive anodal tDCS (transcranial direct current stimulation) of the right dorsolateral prefrontal Cortex (DLPFC).
  • Sham Comparator: sham tDCS
    Participants will receive sham tDCS (transcranial direct current stimulation) of the DLPFC.
