Not Applicable

Active, not recruiting

• Conditions: Smokeless Tobacco Cessation

• Registration Number: NCT06637358
• Lead Sponsor: Duke University

Brief Summary

All participants will receive the EnufSnuff.TXT scheduled gradual reduction (SGR) intervention for 6 weeks and, for those who do not reach the point of quit, includes getting randomized (like the flip of a coin) into either an additional 8-10 weeks of the EnufSnuff.TXT intervention or into receiving an additional 8-10 weeks of the EnufSnuff.TXT intervention along with a dedicated text quit coach to send and receive live support.

Detailed Description

All participants will receive the EnufSnuff.TXT intervention (a text-based personalized reduction plan and daily text-based cessation support messages) for 6 weeks and, for those who report that they have not achieved complete cessation, includes getting randomized into either an additional 8-10 weeks of the EnufSnuff.TXT intervention or into receiving an additional 8-10 weeks of the EnufSnuff.TXT intervention along with a dedicated quit coach to send and receive live text support. The investigators will conduct phone-based or smart phone-based assessments with participants at baseline, end of program, and 7-month follow-up after intervention completion. The investigators will also conduct a brief midpoint check (after the first 6 weeks of intervention) with participants to ask if they have quit using smokeless tobacco. Research staff will email participants redcap surveys at baseline, end of program, and 7-months. Participants will be able to opt for a recorded telephone interview at the 7-month check-in. Each opted-in participant will be interviewed only once.
