- Public TitleA smoking cessation intervention: online cognitive bias training
- Scientific TitleSmoking cognitive bias training online: A randomized control trial
- ACRONYMS-CBM online
- hypothesis1. Participants in the CBM training condition have weaker smoking related cognitive biases than those in the placebo condition
2. Improvement in smoking cessation outcomes in participants in the CBT training condition compared to those in the placebo condition.
3. The effect of the CBT training is moderated by executive functioning
4. The effect of CBT training is moderated by impulsivity related constructs
5. The effect of CBT training is moderated by personality characteristics

- Target number of participants300
- InterventionsThe online sessions start out with an automatized motivational interview followed by Cognitive bias modification (CBM) to reduce attentional bias (AB) and approach-avoidance bias (AAT) toward smoking-related cues and increase smoking cessation.
Condition 1: Both AB + AAT training
Condition 2: AB training + placebo AAT
Condition 3: AAT training + placebo AB
Condition 4: placebo AB and placebo AAT
- Primary outcomeSmoking cessation outcomes include seven-day end-of-treatment, and three-month follow-up, point prevalence abstinence

- Brief summaryThere is a need for effective smoking cessation interventions. The aims of this intervention study are to examine the effectiveness of an online cognitive bias training (approach and attentional bias) in reducing approach and attentional bias for smoking-related cues, as well as increasing smoking cessation outcomes. Participants are randomly assigned to one of four conditions: (1) both attentional bias + approach bias training; (2) attentional bias + placebo approach bias training, (3) approach bias + placebo attentional bias training, (4) placebo attentional bias + placebo approach bias training. Main study parameters and outcomes are: smoking cessation, craving, decrease in cognitive biases, impulsivity-related constructs, executive functioning and motivation to quit smoking.
