Aims:

People with severe mental disorders have much higher rates of smoking and other cancer risk factors compared to the general community. To our knowledge, this is the first randomised controlled trial to evaluate the effectiveness of a multi-component intervention addressing smoking as well as multiple health behaviours among people with a severe mental disorder. The Healthy Lifestyles Project was a randomized control trial aimed at addressing multiple behavioural health risk factors and this paper reports smoking outcomes.

Methods:

Participants diagnosed with psychotic disorders residing in the community who were smoking 15 or more cigarettes per day (CPD) were randomly assigned to either a multi-component face-to-face intervention addressing multiple health risk behaviours or to a telephone intervention addressing smoking only. There were 8 weekly, 3 fortnightly and 6 monthly sessions scheduled, of approximately 60 minutes duration in the face-to-face condition and 10 minutes in the telephone condition. Nicotine replacement therapy was provided.

Preliminary Results:

At baseline, participants (N=236, Mean age=41.68, 59% male) were smoking on average 28.2 (SD= 14.65) CPD. Point prevalence abstinence (last 28 days) was 11% at 15 weeks and 12% at 12-months for the face-to-face condition and 12% and 9% respectively for the telephone condition. At 15 weeks and 12-months, participants significantly reduced their CPD for both the face-to-face (M=13.72, SD=12.38; M=18.87, SD =14.93) and brief telephone interventions (M=14.26, SD=11.67; M=17.32, SD =14.93), p<.001.

Conclusions:

Face-to-face (focused on multiple health risk behaviours) and telephone-delivered interventions (focused on smoking) are feasible among people with severe mental disorders.
