Specifying cigarette smoking and quitting among people with serious mental illness.

People with serious mental illnesses (SMI) have a high prevalence of cigarette smoking. Details of their smoking and quitting behaviors are needed to create effective interventions. This study aims to describe the smoking and quitting histories, current behaviors, and motivations of an outpatient sample of smokers with SMI. A structured interview and Breathalyzer assessment were administered to 120 smokers from four diverse mental health settings. Participants' smoking and quitting self-report data are presented in combination with demographic and clinical variables; the results provide implications for smoking cessation, amelioration, and prevention interventions and for future research.
