Brief summary

This phase I trial studies how well a new electronic (e)-health smoking cessation program (called Vet Flexiquit) works in promoting smoking cessation in low-income veterans who may or may not be ready to quit smoking. The study will compare the new website smoking cessation program to the current standard care website smoking cessation program offered by the Veterans Administration (VA). Both website interventions will be accompanied by a text messaging program that includes: (1) motivational messages, and (2) reminders to use the assigned program. Both of the website interventions can help smokers quit or cut back on how much they smoke, thus dramatically reducing their chances of developing tobacco-related health conditions.

Detailed description

OUTLINE: Participants are randomized to 1 of 2 arms. ARM I: Participants use the new website smoking cessation program, which provides values driven, mindfulness based coping skills and utilizes non-judgmental acceptance of uncomfortable internal states like cravings. Participants also receive text messages consisting of motivational messages and reminders to use the program. At the end of the program, participants receive an email with handouts and available resources provided by the VA for continued support for smoking cessation. ARM II: Participants use the VA standard of care website, which provides educational materials about cessation treatments, tools to cope with urges and relapse, how to stay motivated, and brief tips on coping with physical and mental health problems. Participants also receive text messages consisting of motivational messages and reminders to use the program. At the end of the program, participants receive an email with a handout of available resources provided by the VA for continued support for smoking cessation. After study randomization, participants are followed up at 1 and 3 months.

Design outcomes

Primary

MeasureTime frameDescription
Satisfaction With Assigned TreatmentAt 3 months post-randomizationSatisfaction ratings regarding the usefulness of specific components of the website program, user comments and suggestions for improvement, presented descriptively. Treatment satisfaction items are reported on a Likert-type scale, with response choices ranging from not at all satisfied to very satisfied. Will dichotomize values at a threshold of somewhat satisfied or higher. We tested for differences between arms using a Fisher's Exact test.
Number of Server-recorded Logins to Assigned WebsiteAt 3 monthsWill use negative binomial regression with adjustment for the stratification variable and baseline readiness to quit (high versus low) to compare treatment effects on the count outcome number of logins. There were no potential confounders to adjust for.
Duration of Website Use (Days Since First Login)At 3 monthsWill use negative binomial regression with adjustment for the stratification variable baseline readiness to quit (high versus low) to compare treatment groups on the secondary acceptability outcome of duration of site usage (number of days elapsed from first to last use). There were no confounders to adjust for.

Secondary

MeasureTime frameDescription
Change in Readiness to QuitBaseline up to 3-month follow-upWill be assessed by the Contemplation Ladder on a scale from 0 (no thought about quitting) to 10 (taking action to quit). Will calculate change score as follow-up minus baseline score and use a linear regression model with adjustment for the baseline value of the measure of interest and for the stratification variable and baseline readiness to quit (high versus low) to compare between study arms. There were no confounders to adjust for.
Number of Quit AttemptsAt 3 monthsWill use a negative binomial model with adjustment for the stratification variable and baseline readiness to quit (high versus low) to compare the count outcome number of quit attempts between arms. There were no confounders to address for.
Change in Acceptance of Smoking TriggersBaseline up to 3-month follow-upWill be assessed by the Avoidance and Inflexibility Scale (AIS) on a scale ranging from 0 (never/not at all) to 4 (always/very much/extensively). Will calculate change score as follow-up minus baseline score and use a linear regression model with adjustment for the baseline value of the measure of interest and for the stratification variable and baseline readiness to quit (high versus low) to compare between study arms. There were no confounders to adjust for. This is the AIS Feelings score change.
Cotinine-confirmed, Self-reported Abstinence From SmokingIn the 7 days prior to the 3-month follow upWill use a logistic regression model with adjustment for the stratification variable and baseline readiness to quit (high versus low) to compare smoking abstinence between arms. There were no confounders to adjust for. Missing responses were considered as continued smokers.
Self-reported Abstinence From All Nicotine and Tobacco Products (Except Nicotine Replacement Therapy)In the 7 days prior to the 3-month follow upWill use a logistic regression model with adjustment for the stratification variable and baseline readiness to quit (high versus low) to compare smoking abstinence between arms. There were no confounders to adjust for. The missing responses were considered continued smokers.

Recruitment details

Fifty-three participants were eligible and enrolled in the study. The final sample comprised 49 participants who were randomized between February 3, 2021 and October 22, 2021.

Pre-assignment details

Four participants who were enrolled in the study were not randomized because they were lost to follow-up (n=3) or they withdrew (n=1) prior to randomization.
