NCT02181179

Brief Summary

The primary aim of this research study is to examine the effects of an 8-week yoga program on aspects related to nicotine dependence, stress, and coping during a smoking quit attempt. Guided by initial studies reporting on the effects of yoga on putative mediators of smoking relapse (i.e., cortisol, distress intolerance, withdrawal symptoms), the proposed experiment examines the effects of an 8-week yoga practice on nicotine withdrawal intensity by way of aiding withdrawal characteristics predictive of smoking relapse. The long-term objectives of the proposed line of research are to: (1) inform theoretical models of nicotine withdrawal, (2) guide the development of effective alternative interventions for smokers susceptible to relapse during the critical withdrawal period (i.e., smokers low in distress tolerance), and (3) to help guide behavioral strategies for treating substance addictions broadly.

Outcome Measures

Primary Outcomes (2)

  • Measurement of Objective Stress through Hormonal Biomarkers (Hair & Salivary Cortisol)

    we will collect biological samples of hair and saliva to assess changes in biomarkers in response to yoga, and as a potential mechanism by which yoga may aid in smoking cessation. Saliva samples will be collected with Salivettes (Sarstedt, Rommelsdorf, Germany), plastic vials with cotton dental rolls inside. Participants will complete 2 Salivettes at each of three separate 12-hr collection periods. participants will provide two hair strand samples cut by trained personnel (Gerber et al., 2012; Suave et al., 2007; Meyer \& Novak, 2012). Hair strands are cut close to the scalp from the posterior vertex of the head using surgical scissors.

    Collected at pre-and-post intervention (Baseline and Quit day, Week 9)

  • Minnesota Nicotine Withdrawal Scale-Revised

    MNWS-R (Hughes \& Hatsukami, 1986) is a validated 15-item self-report measure of withdrawal severity rated on a 5 point Likert scale (0 "none" to 4 "severe") that will establish level of nicotine withdrawal as a major outcome assessed between groups during quit period.

    post-yoga Week 9 on Quit day and week 10 follow-up

Secondary Outcomes (11)

  • Self reported anxiety sensitivity - Anxiety Sensitivity Scale (ASI).

    Weekly from pre-to-post intervention (screen, Baseline, weeks 1-10)

  • carbon monoxide (CO)

    Screen, week 0 (baseline), week 9 Quit day, & week 10 follow up

  • Smoking point-prevalence - timeline follow back calendar

    Weeks Screen, 0 (baseline), 1-8 (intervention), 9-10 (quit period)

  • Five Facet Mindfulness Questionnaire (FFMQ).

    Weekly from baseline to post-yoga (week 9)

  • Barratt Impulsiveness Scale (BIS) of Trait Impulsivity

    Eligibility Screen

  • +6 more secondary outcomes

Study Arms (2)

Yoga

ACTIVE COMPARATOR

This will involve participating in at least two 60-minute Vinyasa yoga sessions each week for eight weeks (weeks 1-8). This will begin the week following a baseline laboratory appointment. These sessions will be conducted at a local Austin studio that has numerous locations in the area.

Behavioral: Yoga

Waitlist

NO INTERVENTION

If randomized to this group, participants will complete weekly assessments only and not yoga during their time in the study. Following full completion of the study (i.e., after week 10), participants will be compensated with a voucher for 2 free months of yoga.

Interventions

YogaBEHAVIORAL

The yoga intervention will be an 8-week program involving two 60-minute sessions each week at a local studio with three locations in Austin. Participants will be instructed to take classes deemed within a moderate-to-vigorous intensity dose. Participants will also be encouraged both by the PI and yoga instructors to complete the entire 60 minutes of yoga, urged to do only what is comfortable and not push themselves beyond their physical limits.
