Study Summary

Using a 2x2 randomized factorial design, we will conduct a statewide field trial in Missouri to compare the relative and combined effects of these two strategies for augmenting an existing, evidence-based tobacco quitline program. Among 2000 low-income smokers, half will receive standard Missouri quitline services and half will receive new Specialized Quitline services targeted to this group. In each of these groups, half also will receive calls from a trained navigator to help them address unmet Basic Needs and the accompanying psychological distress that act as barriers to smoking cessation.
