June 15, 2018 updated by: Duke University

Mobile Health Intervention to Help Low-Income Smokers Quit Smoking and Increase Physical Activity

This project proposes to evaluate the feasibility, acceptability, and efficacy of a mobile intervention to target smoking-cessation and increase physical activity among low-income persons. The intervention is called Smoking Treatment and Exercise Program for Underserved Populations (STEP UP).

Detailed Description

This pilot project proposes to evaluate the feasibility, acceptability, and efficacy of a mobile intervention to target smoking-cessation and physical activity among low-income persons. The intervention, named Smoking Treatment and Exercise Program for Underserved Populations (STEP UP), combines a smartphone-based contingency-management application (app), which provides monetary reinforcement for smoking abstinence and physical activity, 5 weeks of telephone-based cognitive-behavioral therapy (CBT) to prevent relapse, nicotine replacement pharmacotherapy, and text-messaging to support physical-activity goals. Participants are given a smartphone, a compact carbon-monoxide (CO) monitor, with which recency of smoking can by determined, and a Garmin Vivosmart wristband step-tracker. Twice a day at semi-random intervals, participants are prompted by the app to submit a video of themselves blowing into the CO monitor. Monetary reinforcement is then immediately provided contingent upon a below-threshold CO reading. The app also continuously syncs with the Garmin step-tracker, providing supportive messaging and bonus incentives-namely doubled reinforcement for smoking abstinence among participants who meet personalized daily step goals. The expected outcome of the project is to provide information to evaluate the efficacy of an innovative approach in preparation for a subsequent larger clinical trial that builds upon the capabilities of mHealth technology to reduce the prevalence of smoking among low income smokers.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: STEP UP
STEP UP is an intervention that combines evidence-based telephone cognitive behavioral counseling for smoking cessation, access to nicotine replacement therapy (NRT; including transdermal nicotine patch and either nicotine polacrilex or nicotine lozenge) and bupropion, and intensive mobile contingency management behavioral therapy administered via a smart-phone based application.
Behavioral: Cognitive Behavioral Counseling
Participants will receive five cognitive-behavioral counseling sessions designed to improve rates of smoking cessation, enhance relapse prevention, and increase physical activity.
Behavioral: Mobile Contingency Management
Participants will be asked to provide video recordings of themselves taking carbon monoxide readings in order to confirm smoking abstinence. They will also be asked to wear a fitness tracker to monitor physical activity (i.e., steps walked). Participants are provided monetary reward for videos that suggest smoking abstinence, and for fitness tracker readings that suggest increased physical activity.
Drug: Bupropion
All participants who are medically eligible will be prescribed bupropion, which they will start two weeks prior to their quit day. Dosage will be 150 mg/daily for days 1-7 and 300 mg/daily (administered in two daily doses) until the 6-month follow-up.
Other Names:
  • Zyban
Drug: Transdermal nicotine patch
Initiated at smoking quit date; 7 mg to 21 mg patch depending on amount smoked by participant
Drug: Nicotine polacrilex
Nicotine gum will be initiated at smoking quit date; 4 mg dose administered as needed
Other Names:
  • Nicotine gum; nicorette
Drug: Nicotine lozenge
Nicotine lozenge will be initiated at smoking quit date; 4 mg dose administered as needed

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Self-report Prolonged Abstinence From Smoking
Time Frame: 6 month follow up
Participants will be asked to report on smoking since two weeks past quit date. Prolonged abstinence is defined as continued abstinence from smoking beginning at 2 weeks post-quit.
6 month follow up
Number of Participants Whose Prolonged Abstinence is Bio-verified
Time Frame: 6 month follow up
Self-reported prolonged abstinence (primary outcome) will be verified by cotinine assay. Saliva samples will be collected from participants who self-report prolonged abstinence. Prolonged abstinence is defined as continued abstinence from smoking beginning at 2 weeks post-quit.
6 month follow up
Number of Participants Who Self-report Prolonged Abstinence From Smoking
Time Frame: 3 month follow up
Participants will be asked to report on smoking since two weeks past quit date. Prolonged abstinence is defined as continued abstinence from smoking beginning at 2 weeks post-quit.
3 month follow up
Number of Participants Whose Prolonged Abstinence is Bio-verified
Time Frame: 3 month follow up
Self-reported prolonged abstinence (primary outcome) will be verified by cotinine assay. Saliva samples will be collected from participants who self-report prolonged abstinence. Prolonged abstinence is defined as continued abstinence from smoking beginning at 2 weeks post-quit.
3 month follow up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants Who Self-report 7 Day Point Prevalence Abstinence From Smoking
Time Frame: 6 month follow up
7-day point prevalence abstinence is defined as no smoking in the prior 7 days.
6 month follow up
Number of Participants Who Report 30 Day Point Prevalence Abstinence From Smoking
Time Frame: 6 month follow up
30-day point prevalence abstinence is defined as no smoking in the prior 30 days.
6 month follow up

Total number of days of moderate and hard exercise in last 7 days will be compared to self-reported values at baseline (i.e., # of days of exercise in past 7 days at 3-month follow-up minus # of days of exercise in past 7 days at baseline).
baseline and 3 month follow up
Change in the Number of Days in Which Smoked Compared to Pre-quit Use
Time Frame: 3 month follow up
Participants will self-report number of days smoked in the past 30 days and this will be compared to self-reported number of days smoked in 30 days prior to quit.
3 month follow up
Change in Number of Cigarettes Smoked Per Week Compared to Pre-quit
Time Frame: 3 month follow up
Self-reported number of cigarettes smoked each day in past 7 days; this will be compared to self-reported amount smoked in week prior to quit date
