Brief summary

The primary aim of this study is to pilot test a novel reactive carrot approach for improving individuals' ability to stick to a practice quit program in a smoking cessation context. In this study, the treatment gives subjects an offer to forego a monetary incentive to forego the opportunity to receive subsequent abstention (contingency management) rewards.

Detailed description

All the subjects, treatment and control groups, would be given the opportunity to receive attendance rewards for attending six CO testing meetings as well as abstention (contingency management) rewards for abstaining from smoking. The only difference between the subjects randomly assigned to treatment and control groups is that each member of the treatment group would be tempted at the beginning of their program by being offered a one-time monetary incentive to forego the opportunity to receive subsequent abstention (contingency management) rewards. Treatment group subjects would, at their initial intake meeting after the attendance and abstention rewards opportunity had been described, be given a one-time opportunity to received $80 temptation payment to give up the opportunity to receive subsequent abstinence (contingency management) rewards that could be worth as much as $165. Subjects who accepted this one-time opportunity would remain enrolled in the practice quit smoking and they would still be eligible to receive attendance reward compensation totaling up to $30 for showing up to their six testing appointments. The purpose of the study is to test whether resisting the temptation to accept the one-time payment helps steel the resolve of the treatment subjects to follow through and make sure that they earn the subsequent contingency management rewards. More specifically, an intent-to-treat design will allow us to test whether the temptation causes treatment group subjects to have greater success than the un-tempted control group subjects to abstain from smoking during the two-week practice quit period.

Interventions

BEHAVIORALContingency Management

The treatment group will receive a onetime offer of $80 (a reactive carrot) to forego all abstinence (contingency management) reward payments in the future.

BEHAVIORALControl

The control group will receive contingency management payments and other monetary benefits for completing the trial.

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Breath Carbon Monoxide Test (measured in ppm levels)14 days following intake dateA primary outcome is the sum of times a subject tested abstinent at the 6 CO testing meetings. To test for abstinence, a breath carbon monoxide test will be used to determine exposure to smoke. Abstinence will be coded as expired-air carbon monoxide (CO) levels below 5 ppm.
Proportion of CO (CO ≤ 4ppm)14 days following intake dateProportion of 6 CO tests showing abstinence (CO ≤ 4ppm)
Maximum number of consecutive abstinent days14 days following intake dateThe maximum number of consecutive abstinent days for each subject will be measured

Secondary

MeasureTime frameDescription
Reduced smoking14 days following intake date, as well as 1 month and 6 months after intake dateWhether subjects report reduced smoking will be used to measure reduced smoking habits
Time to first relapse14 days following intake dateTime to first relapse will be measured by subjects self-reporting use of different types of tobacco products or cigarette alternatives
Attrition14 days following intake dateAttrition will be measured by participants ability to make their testing appointments.
Contingency Management Payment14 days following intake dateTotal amount of abstention (contingency management) rewards paid to subjects.
