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.

Interventions

BEHAVIORALExtended Scheduled Gradual Reduction (SGR)

The extended SGR program will allow participants additional time to reduce smokeless tobacco use until they reach zero. The intent of this program is to reduce the number of times participants use smokeless tobacco down to zero. Participants will also receive text-based support messages.

BEHAVIORALQuit Coach

Weekly check-ins and support will be given to this group via the quit coach interactions. The intent of this program is to reduce the number of times participants use smokeless tobacco down to zero. Participants will also receive text-based support messages.
