Study Details

Brief summary:

The goal of this pilot study is to assess whether 4-weeks of verified smoking abstinence following financial incentive treatment for smoking cessation improves physiological markers of chronic pain risk in adult Native American smokers.

The main aims to answer are:

1. Determine study feasibility.
2. Obtain effect sizes for changes in pain amplification and pain inhibition in abstinent vs non-abstinent Native Americans.
3. Obtain effect sizes for variables in the conceptual model of the Native American smoking-pain relationship.

experimental: Smoking Cessation

Interventions

Smoking Cessation

Investigators will provide financial incentives for biochemically verified abstinence at 4 weeks following treatment. This incentive is consistent with recent research using macro-level financial incentives and incorporates both short-term and long-term incentives to shape behavior.

Primary outcome measure

  • Pain inhibition [ Time Frame: Baseline (1 day prior to smoking cessation treatment allocation) and Post-Treatment (following 4 weeks of treatment + 4 weeks of verified smoking abstinence) ]
  • Inhibition of pain-related spinal reflex [ Time Frame: Baseline (1 day prior to smoking cessation treatment allocation) and Post-Treatment (following 4 weeks of treatment + 4 weeks of verified smoking abstinence) ]
  • Allostatic load [ Time Frame: Baseline (1 day prior to smoking cessation treatment allocation) and Post-Treatment (following 4 weeks of treatment + 4 weeks of verified smoking abstinence) ]
  • Pain amplification [ Time Frame: Baseline (1 day prior to smoking cessation treatment allocation) and Post-Treatment (following 4 weeks of treatment + 4 weeks of verified smoking abstinence) ]
