Enhanced E-cigarette Coaching Intervention for Dual Users of Cigarettes and E-cigarettes

In Phase 2, average treatment satisfaction and acceptability rating will be compared for EEC and TAU participants. Full 1-6 scale description: 1 - very satisfied; 2 - satisfied; 3 - somewhat satisfied; 4 - somewhat dissatisfied; 5 - dissatisfied; 6 - very dissatisfied. Participants can also respond "I don't know" or "I prefer not to answer". On scale 1-6, 1 is the best outcome.

In Phase 2, call completion (captured via standard quitline data systems) will be compared for EEC and TAU participants. There is no limit to number of calls that can be completed, although participants are called to complete 5 scheduled calls (best outcome).

In Phase 2, quit plan development experience will be compared for EEC and TAU participants. Quit plan development experience will be measured with an adapted version of the CollaboRATE (not an abbreviation) shared decision making assessment measure. The adapted CollaboRATE measure included 3 questions (on a 5-point scale from "no effort (0)" to "every effort was made (4)"): "How much effort was made to help you understand your options for quitting smoking?", "How much effort was made to listen to the things that matter most to you about your plan for quitting smoking?", and "How much effort was made to include what matters most to you in creating your plan for quitting smoking?". Higher total scores indicate greater utilization of a shared decision-making approach during quit plan development. Scale minimum equals 0 and maximum equals 12.

In Phase 2, Knowledge and Beliefs about ENDS, Smoking, and FDA-approved Cessation Medications was assessed via 3 relative risk questions about ENDS, Smoking, and FDA-approved Cessation Medications designed for this study, and compared for EEC and TAU participants.
