There is growing evidence showing that smoking reduction increases the probability of future cessation among samples without psychiatric disorders (Asfar, Ebbert, Klesges, & Relyea,2011; Hughes & Carpenter, 2006). For smokers with psychiatric disorders, Hitsman, Moss, Montoya, and George (2009) suggest to include smoking reduction as an initial goal for improving treatment efficacy. For individuals with schizo
phrenia, three different areas may reduce smoking behavior: limiting access to cigarettes, use of nicotine-replacement therapy (NRT) drug and behavior change (McChargue, Gulliver, & Hits- man, 2002). In this context, the “oxygen group” (OG) intervention endeavours to initiate a behavior change based on counseling and exercise.
