Treating tobacco dependence: Development of a smoking cessation treatment program for outpatient mental health clinics

Efficacy of a group tobacco cessation behavioral intervention among tobacco users with concomitant mental illness in Kenya: protocol for a controlled clinical trial

BACKGROUND

The rate of tobacco use among people with mental illness is nearly twice that of the general population. Psychotropic medications for tobacco cessation are relatively expensive for most Kenyans. Behavioral counseling and group therapy are effective lower cost strategies to promote tobacco cessation, yet have not been studied in Kenya among individuals with concomitant mental illness.

METHODS/DESIGN

One hundred tobacco users with mental illness who were part of an outpatient mental health program in Nairobi, Kenya were recruited and allocated into intervention and control groups of the study (50 users in intervention group and 50 users in control group). Participants allocated to the intervention group were invited to participate in 1 of 5 tobacco cessation groups. The intervention group received the 5As (Ask, Advise, Assess, Assist and Arrange) and tobacco cessation group behavioral intervention, which included strategies to manage cravings and withdrawal, stress and anxiety, and coping with depression due to withdrawal; assertiveness training and anger management; reasons to quit, benefits of quitting and different ways of quitting. Individuals allocated to the control group received usual care. The primary outcome was tobacco cessation at 24 weeks, measured through cotinine strips. Secondary outcomes included number of quit attempts and health-related quality of life.

DISCUSSION

This study will provide evidence to evaluate the efficacy and safety of a tobacco cessation group behavioral intervention among individuals with mental illness in Kenya, and to inform national and regional practice and policy.

The co-occurrence of cigarette smoking and bipolar disorder: phenomenology and treatment considerations

OBJECTIVES

  Despite recent advances in understanding the causes and treatment of nicotine dependence among individuals with psychiatric disorders, smoking among individuals with bipolar disorder (BD) has received little attention. The goal of this review is to synthesize the literature on the epidemiology, consequences, and treatment of smoking and nicotine dependence among individuals with BD and to delineate a future research agenda.

METHODS

  We conducted a PubMed search of English-language articles using the search terms bipolar disorder, mania, tobacco, nicotine, and smoking, followed by a manual search of the literature cited in the identified articles. Articles were chosen by the authors on the basis of their relevance to the topic areas covered in this selective review.

RESULTS

  Adults with BD are two to three times more likely to have started smoking and, on the basis of epidemiological data, may be less likely to initiate and/or maintain smoking abstinence than individuals without psychiatric disorders. Smoking cessation is achievable for individuals with BD, but challenges such as chronic mood dysregulation, high prevalence of alcohol and drug use, more severe nicotine dependence, and limited social support can make quitting more difficult. Effective treatments for tobacco cessation are available, but no controlled trials in smokers with BD have been conducted.

CONCLUSIONS

  Cigarette smoking is a prevalent and devastating addiction among individuals with BD and should be addressed by mental health providers. Additional research on the mechanisms of, and optimal treatment for, smoking and nicotine dependence in this population is desperately needed.

Implications of participant self-selection for generalizability: who participates in smoking laboratory research?

The generalizability of data from laboratory smoking studies using volunteer samples is debatable. We tracked potential participants from first contact with research staff through screening to study completion. We found that a minority of individuals were ultimately enrolled in the study. Failure to enroll was as often a function of participant lack of attendance at the laboratory as a function of ineligibility. With some exceptions, groups of potential participants were similar regarding demographic characteristics and substance use history. These findings support the generalizability of the sample and highlight the importance of documenting details of study eligibility and participation. The study's limitations are noted.
