Clinical Trial Summary

A randomized control trial evaluating a novel smoking cessation intervention in individuals at a an inpatient clinic for clients with addiction and concurrent disorders. The intervention is based on cognitive bias modification, where participants are explicitly or implicitly trained to make avoidance movements by pushing a joystick in response to pictures of smoking, and as a result altering their cognitive biases towards smoking and tobacco dependence. Hypothesis: Participation in the experimental (tobacco-avoidance) condition will induce reduction of smoking, assessed as lower levels of carbon monoxide measured at baseline and 12 week follow-up.

Intervention

Behavioral:
TRAA intervention
The Tobacco Retraining of Automatic Approach The tobacco-RAA will be the intervention in changing approach tendencies towards tobacco. The task uses pictures of tobacco related objects (e.g, a cigarette) and pictures of non-tobacco related objects (e.g, a spoon). Patients will be presented with a joystick while pictures are presented on a computer screen. Patients will be presented with pictures, pulling pictures in a portrait format, while they push pictures in a landscape format. In the experimental condition pictures pushed will almost exclusively be smoking related pictures. In the control condition smoking pictures will be equally divided into push and pull conditions.

Outcome

Type Measure Description Time frame Safety issue
Primary Carbon monoxide levels in breath The breath carbon monoxide monitoring device will be used both before the intervention for a baseline measure and at the 12-week follow-up for comparison. These two measurements will be used to detect changes in smoking patterns that may have occurred during this interval. The method allows to objectify abstinence from smoking. baseline, 12 weeks
Secondary Fagerström test for Nicotine dependence (FTND) The FTND is a 6-item questionnaire scored to test level of nicotine dependence, and will be presented to patients prior to the intervention. Patients meeting a cut-off score of 5 or higher will be eligible to participate in the intervention portion of this study. Baseline
