Pilot Randomized Controlled Trial of a Smart Phone-Based Smoking Cessation Program

June 27, 2024 updated by: Jennifer Marler, MD
Two-arm, parallel-group, non-crossover, single-center pilot randomized controlled trial, enrolling up to 180 participants to evaluate the effect of the Pivot smoking cessation program (intervention) compared to usual care (commercially available app smoking cessation program plus optional nicotine replacement therapy, control).

Detailed Description

The present pilot randomized controlled trial compares user engagement and retention, change in attitudes towards quitting smoking, change in smoking behavior and participant feedback in adult smokers randomized either to the Pivot (intervention) or commercially available (control) smoking cessation programs.

We aim to assess participants' use of Pivot program and commercially available program. There will be a focus on assessing use and engagement, changes in attitudes towards quitting smoking and changes in smoking behavior over the course of the 2-year study, as well as participant feedback on the set-up, design, use experience, and impact of each program.

User Satisfaction - Net Promoter Score (NPS)
Time Frame: 4 weeks, 12 weeks, and 26 weeks

User satisfaction with the smoking cessation program, specifically the likelihood of recommending the program to a friend. Measured with a net promoter score (NPS).

Participants are asked "How likely are you to recommend your study program to a friend or colleague?" and answer on a 10-point (1-10) scale (where 1=Not at all likely and 10=Very likely).

NPS was calculated for each study group by subtracting the percentage of respondents who answered ≤6 (detractors) from the percentage of respondents who answered 9 or 10 (promotors).

NPS formula = %promotor - %detractor NPS has a score range between -100 and 100 (-100 indicates 100% detractors, 100 indicated 100% promotors of the program).

A higher NPS score indicates greater promoters of the program, and thus a greater likelihood of individuals recommending the program to a friend.
