A Guided Imagery Tobacco Cessation Intervention Delivered by a Quit Line and Website

Tobacco use is still the leading cause of preventable disease and death in the United States. Tobacco quit lines are effective at helping smokers to quit, but quit lines are underutilized, especially by men and racial/ethnic minorities. Guided imagery is effective at helping people quit smoking, and is appealing to males and diverse racial groups, but has limited reach. The proposed study will develop and test the feasibility and acceptability of a guided imagery tobacco cessation intervention that is delivered by a combination of quit line coaches and an interactive website. The investigators hypothesize that guided mental imagery delivered using the quit line "coaching model" combined with an interactive website could be an effective intervention strategy.

About this study

The objective of this three year R34 application is to develop and test the feasibility of a theory-driven, telephone plus web-based, guided mental imagery intervention for smoking cessation.

Aim 1. Develop a theory-based, guided mental imagery tobacco cessation intervention for quit line callers with input from expert consultants in health disparities and a Community Advisory Board representing diverse populations and tobacco control stakeholders. The intervention will include phone-based coaching, an interactive website, and optional cessation medication. It will be focus tested with 40 smokers (from diverse racial/ethnic and age groups with at least 40% males), and usability tested with 5 smokers.

Aim 2. Develop training and competency standards for, and train, four coaches in the implementation of the guided imagery and control interventions. Coaches will be assessed at 6-weeks and 6-months post-training for implementation fidelity and satisfaction.

Aim 3. Conduct a feasibility trial (N=100) to gather preliminary data on the effects of the guided mental imagery intervention on quit line callers' tobacco use, cravings, and self-efficacy to quit smoking, and to refine study procedures, including recruitment, retention, and use of intervention components. Participants will be randomly assigned to receive either the Imagery Intervention (N=50) or an attention control condition (N=50) as delivered by study coaches. Participants will be assessed at baseline, 6-weeks and 6-months post-enrollment. Primary outcomes will be self-reported point prevalence and prolonged abstinence of tobacco use. Biochemical validation will be conducted on a sub-sample to determine validity of self-reported abstinence in this population. Secondary outcomes will be self-reported cravings and self-efficacy.

Primary outcomes

  1. Number of Participants With Change in Self-reported 7-day Tobacco Abstinence From Baseline to Follow-up

    Time frame: 6 months

    Tobacco use over the past seven days is assessed by project staff at 6-months post-enrollment. Tobacco use includes cigarettes, smokeless tobacco, and other types of tobacco. The question is asked "Have you smoked, even a puff, in the last 7 days?" "Have you used any other form of tobacco in the last 7 days?" If yes to either question, the participant is asked to indicate what type of tobacco was used and how much was used (e.g., "how many cigarettes did you smoke on a typical day?").

  2. Number of Participants With Change in Self-reported Tobacco 30-day Abstinence From Baseline to Follow-up

    Time frame: 6 months

    Tobacco use over the past 30 days is assessed by project staff at 6-months post-enrollment. Tobacco use includes cigarettes, smokeless tobacco, and other types of tobacco. The question is asked "Have you smoked, even a puff, in the last 30 days?" "Have you used any other form of tobacco in the last 30 days?" If yes to either question, the participant is asked to indicate what type of tobacco was used and how much was used (e.g., "how many cigarettes did you smoke on a typical day?").

Secondary outcomes

  1. Change in Tobacco Use for Non-quitters From Baseline to Follow-up

    Time frame: 6 months

    Assessed by project staff at 6-months post-enrollment.

  2. Change in Self-efficacy for Quitting From Baseline to Follow-up

    Time frame: 6 months

    An abbreviated version of the Condiotte and Lichtenstein (1981) Confidence Questionnaire consisting of 5 items for quitters and 6 items for non-quitters. All items are scored using a 5-point Likert scale where 1 is low/less and 5 is high/more. We calculated an average score of the items (which would have a value between 1 and 5).

  3. Change in Nicotine Cravings From Baseline to Follow-up

    Time frame: 6 months

    This was assessed using 1 item adapted from the Shiffman (2004) Rating Scale ("How much have you craved tobacco today?"). Responses were coded using a 6-point Likert scale from "not at all" (code 0) to "a great deal" (code 5).
