In an attempt to reduce smoking-related health disparities, investigators will implement a
text messaging-based smoking cessation intervention in collaboration with state quit lines.
The approach is based on the successful STOMP (STOp smoking by Mobile Phone) program, a text
messaging-based smoking cessation intervention among young Maori adults in New Zealand.
Investigators will adapt the STOMP intervention, which will result in a new intervention
known as AI STOMP (American Indians STOp smoking by Mobile Phone).The primary aim of the
study is to determine the effectiveness of the AI-STOMP intervention in smoking cessation
among American Indians.

This is a randomized, single-blinded, controlled trial examining the effectiveness of a text
messaging-based smoking cessation program among American Indian (AI) smokers who call state
quit lines, in states with high AI populations. Participants will be randomized to either
receive culturally-tailored text-messages to support smoking cessation or quit line's
treatment as usual.

Participants will be recruited by Optum, the company who runs many state quit lines in the
US. If - after answering some demographic questions for Optum from the following states:
Alaska, Oklahoma, Wisconsin, Minnesota, and New Mexico - a person is found to be a AI/AN and
18+ years old, that person will be asked if they would like to receive information about the
study. If they answer yes the WSU research team will receive their contact information from
Optum via a secure email, and WSU researchers will send a text explaining the study in more
detail and a link to the e-consent form.

Participants will also fill out 4 baseline questionnaires. After filling out baseline
questionnaires, participants will be randomized to either the intervention group or the
control group. Participants will be stratified into the intervention and control groups based
on their age, gender, and Fagerstrom nicotine dependence score. Random permuted blocks will
be used by on-campus research staff to manually assign participants to the two research
groups.

All participants will begin receiving text messages one week before their chosen quit date.
