title: Carbon monoxide feedback in a motivational decision support system for nicotine dependence among smokers with severe mental illnesses.
abstract: Health concerns are common reasons for wanting to quit smoking among smokers with mental illnesses. Motivational interventions have used feedback from a carbon monoxide monitor to increase awareness of health concerns, but this device is not commonly available. Whether brief motivational interventions can be effective without this feedback is unknown. Using a randomized controlled trial, this study tested the effect of carbon monoxide feedback within a brief, multi-component, computerized motivational intervention among 124 smokers with schizophrenia or mood disorders. The main outcome was initiating cessation treatment over two months. Although participants in the carbon monoxide group increased their knowledge about the carbon monoxide, (χ(2)=6.97, df=1, p=.008), the main and secondary outcomes did not differ significantly between groups. Overall, 32% of participants initiated treatment. This study suggests that a computerized motivational decision support system can lead users to initiate cessation treatment, and that carbon monoxide feedback is not a necessary component.
