Brief Summary

Smoking is the leading cause of morbidity and mortality in the U.S. Interventions that increase successful quit attempts among depressed smokers with chronic medical illnesses are particularly important for the VA healthcare system because rates of tobacco use, depression, and chronic medical illnesses are significantly higher among Veterans compared to the general population. Providing smoking cessation services augmented with mood management to Veterans via telephone may increase access to, and utilization of, evidence-based smoking cessation counseling and decrease rates of smoking-related complications for Veterans with chronic medical illnesses and depression. Yet, the reach of smoking cessation telephone counseling has been limited among populations with mental illness. The investigators intend to combine the potency of co-delivered mood management and reach of telephone-delivered interventions by testing the telephone delivery of behavioral mood-management for smoking cessation among smokers with depression and chronic medical illness.

Detailed Description

Purpose: Cigarette smoking is the single greatest cause of preventable deaths. In the VA health care system, patients with chronic medical illnesses represent an important population on which to focus smoking cessation efforts. Smoking cessation among patients with chronic medical illnesses can substantially decrease morbidity and mortality. Despite these benefits, many patients with chronic medical illnesses continue to smoke. There is a strong interrelationship between depression and chronic medical illness. Depression can derail sustained smoking cessation and may be an important barrier to smoking cessation for Veterans with chronic medical illness. Despite the barriers they face, smokers with depression are motivated to quit smoking. Smokers with histories of depression may respond better to smoking cessation interventions that are augmented with mood-management adjuncts such as mood-management counseling. Thus, depressed smokers are more likely to quit when behavioral mood-management is added to traditional cessation approaches. Yet, the augmentation of smoking cessation with behavioral mood management is not yet firmly established. Also these intensive interventions have limited reach when conducted in person. Telephone counseling can deliver intensive and effective treatment to people who smoke, yet its implementation has been limited among smoker with depression. There is a need to develop novel proactive telephone-delivered approaches that can broadly deliver intensive smoking cessation interventions to Veterans who may not respond to standard care, such as those with chronic medical illnesses and depressive symptoms.

Methodology: The investigators propose a randomized comparative effectiveness trial with a two-group design in which 350 Veteran smokers with depression and chronic medical illness will be randomized to either: 1) smoking cessation plus adjunctive behavioral mood management (SMK-MM group), an intervention that includes a proactive telehealth intervention that combines evidence-based smoking cessation counseling augmented with behavioral mood management and a tele-medicine clinic for accessing nicotine replacement therapy (NRT), or 2) smoking cessation telephone counseling control (SMK CONTROL), a contact-equivalent control that provides the same smoking cessation telephone counseling intervention augmented with health education (instead of mood-management) and a tele-medicine clinic for accessing NRT. Patients with chronic medical illnesses will be identified from patient intake systems of the Durham Veteran's Affairs Hospital and screened for tobacco use and depressive symptoms.

The main outcome in this trial is prolonged abstinence at 6-month and 12-month follow-up. Logistic regression will be used to test for a between-group difference in the proportion of patients with self-reported prolonged abstinence from cigarettes at 6 months. A general linear mixed model will be used to estimate changes depressive symptoms between groups. If there is a significant intervention effect on smoking cessation, mediational analysis will be conducted to examine whether changes in self-efficacy or affect mediate the impact of the mood management intervention.

Objectives: The specific aims of the study are to 1) evaluate the impact of a telephone-delivered smoking cessation intervention augmented with behavioral mood management on rates of prolonged and point prevalence abstinence from cigarettes among Veterans with chronic medical illnesses and depression; 2) monitor the impact of behavioral mood management intervention on depressive symptoms; 3) if effective, assess whether change in self-efficacy as well as positive and negative affect mediate the impact of behavioral mood management intervention on smoking cessation among Veterans; and 4) assess the cost-effectiveness if the mood-enhanced intervention.

Study Groups

Mood management enhancement

In the SMK-MM enhanced arm, behavioral mood management will be integrated into the evidence-based smoking cessation counseling.

Group Type: EXPERIMENTAL

Behavioral mood management

Intervention Type: BEHAVIORAL

The mood-management sessions are informed by CBT and emphasize psycho-educational and skills-based approaches to CBT. CBT has been used extensively to address mood management. Specifically, SMK-MM enhancement includes behavioral activation, cognitive restructuring (working with automatic thoughts, problem solving, and behavioral skills (i.e., activity scheduling, relaxation training/controlled breathing). The SMK-MM-enhanced participant manual will also include additional worksheets developed for the investigator's pilot based on Lewinsohn's self-help guide to controlling depression. The main objective of the worksheets will be to provide Veterans with an opportunity to gain mastery over selected behavioral and cognitive skills thought to facilitate mood management. As is customary in CBT, homework based on the worksheets will be discussed during counseling calls.

Health education control

In the contact-equivalent health education condition, participants will receive parallel smoking cessation content on the same schedule as in the MM-enhanced arm; however, health education content will supplant the MM content. The educational content will be based on the VA National Center on Health Promotion and Disease Prevention's "Health Living Messages" on such topics as being safe, eating wisely, getting recommended immunization and screening tests, and being involved with personal health care. Participants also will receive chronic-disease-specific self-management information.

Group Type: OTHER
