Abstract

Smoking among individuals with serious mental illness (SMI) creates significant health problems. This study explored stage of change transitions over time among smokers with serious mental illness (SMI) and how dose of a brief intervention and other psychosocial variables were related to stage transitions. Participants were a subsample of 110 patients who participated in a larger controlled trial (Dixon, et al., 2009) examining whether psychiatrists in mental health clinics implementing the “5A's” (Ask, Advise, Assess, Assist, and Arrange) significantly reduced smoking among persons with SMI. Participants were classified into one of the Transtheoretical Model (TTM) Stages of Change for Smoking Cessation as well as classified into groups based upon the pattern of stage status transitions over time (i.e., Regressors, Stable, Inconsistent, Progressors with and without a successful quit). Modest quit rates for this brief intervention were found at one-year (6.4%) and the dose of the intervention was meaningfully related to positive stage transitions. Cessation outcomes from the controlled trial (Dixon, et al., 2009) indicated a small effect on smoking cessation, which is confirmed in this stage transition secondary analysis with a subset of these smokers. However, these results suggest that a brief intervention delivered by psychiatrists in a mental health treatment setting does seem to make an impact on these smokers.

Research Highlights

► Individuals with serious mental illness (SMI) continue to smoke at alarming rates. ► Cessation rates are low and interventions are under-utilized in this population. ► A psychiatrist-delivered, brief intervention can positively impact smokers with SMI. ► SMI smokers move through the process of change in similar ways to other smokers. ► As with non SMI smokers success comes after multiple attempts, relapse, and recycling.

Introduction

Individuals with serious mental illness (SMI) continue to smoke at alarming rates, with prevalence rates as high as 90% among individuals with schizophrenia (de Leon et al., 1995, Williams and Ziedonis, 2004), compared to smoking rates of only 20–25% in the general population. Moreover, Kelly and McCreadie (1999) found that more than two-thirds of smokers with schizophrenia smoked 25 or more cigarettes daily compared to only 11% in the general population. Smokers with psychiatric illnesses and substance abuse disorders are estimated to consume about 44% of cigarettes smoked in the United States (Lasser et al., 2000), which may lead to approximately 200,000 deaths per year (Williams & Ziedonis, 2004).

Cessation rates are low in this population, interventions are under-utilized, and encouragement to quit is infrequent, even by health professionals (Addington, 1998). Despite lower cessation rates, over half of the SMI smokers want to quit (Forchuk et al., 2002). Increasing motivation to quit is a key element for successful cessation (DiClemente et al., 2004, DiClemente et al., 1991) and essential to protect the health of this vulnerable population. A best-practice, brief intervention designed to increase motivation to change smoking behavior involves having health care providers Ask, Advise, Assess, Assist and Arrange for follow-up for all smokers (5A's) in healthcare settings (Fiore et al., 2008). One of the few studies to evaluate efficacy of the 5A's with SMI smokers examined physician-delivered 5A's in public mental health clinics and reported modest effects of the 5A's for reducing tobacco use and increasing cessation rates 12 months after the intervention phase (Dixon et al., 2009). Specifically, the number of individuals who reported smoking in the past seven days and the number of cigarettes typically smoked in a week differed significantly, but abstinence confirmed by CO ppm < 10 did not. These modest changes are significant since the intervention was low-impact and patients were not chosen based on readiness to change. In addition, by implementing the intervention with most of their patients who smoked, psychiatrists demonstrated the acceptability and feasibility of integrating 5A's, or at least 3A's (Ask, Advise, and Assess) into treatment.

Stages and other process of change variables from the Transtheoretical Model of Behavior Change (TTM) have predicted the likelihood of quit attempts and cessation outcomes (DiClemente et al., 1991) and could be related to progress toward cessation in SMI smokers as well. Theoretically, smokers in more advanced stages (i.e., Contemplation or Preparation) would be more likely than those in Precontemplation to quit smoking. Processes of change, engaging in appropriate coping activities at the right time, decisional considerations and both self-efficacy and temptation to smoke are also related to the probability of cessation success. Specifically, in the early stages, such as Contemplation and Preparation, experiential processes appear more salient with behavioral processes usually increasing in later action stages (DiClemente, 2003). In addition, when quitting an addictive behavior, it is generally expected that abstinence self-efficacy would increase and levels of temptation drop (Velicer, DiClemente, Rossi, & Prochaska, 1990).

This study examined how changes in stage status and how other process dimensions (coping processes of change, abstinence self-efficacy, temptation to smoke as well as the pros and cons of smoking) were associated with changes in stage transitions over time for individuals with SMI. We evaluated stage of change transitions over time among a sample of SMI smokers who had participated in a larger study examining a provider-based implementation of the 5A's for the smoking cessation intervention during their outpatient psychiatric care (Dixon et al., 2009). The study examined how stage transitions were related to process of change variables.

Study setting and sample

This study analyzed data from a subsample of the original 304 smokers who were in treatment at six community mental health centers in the greater Baltimore area, had a diagnosis of schizophrenia or other psychotic illness, and had participated in the original study. The subsample for analyses included only participants who were assessed at baseline, 6 months and 12 months and who had complete baseline data for stages of change (n = 110). A full description of the sample, methodology, and smoking

Description of sample

The analysis sample (n = 110) was balanced with respect to gender (53, 48.2% male; 57, 51.8% female) and race (49, 44% White; 54, 49% African-American; 7, 6% other) with a mean age of 44.1 (SD = 6.2) years. Three-quarters of these SMI smokers were diagnosed with schizophrenia (n = 81); the remainder (26%) with affective psychoses. Most (81%) had been smoking for over 20 years and began smoking on average at 15.3 (SD = 5.9) years of age. As required by eligibility criteria, all participants had smoked in

Discussion

Stage of change transitions for SMI smokers over the one year follow-up indicated variable patterns of movement through the stages of change as reported in prior studies of smoking (Kohler et al., 2008, Martin et al., 1996, Prochaska et al., 1991) and other behaviors (Feldman et al., 2000). Although movement into the action stage and abstinence at one year was modest (6.4%) during this low intensity intervention, it is on par with self-change success estimates (Cohen et al., 1989). Although SMI
