mMotiv8: A Smartphone-Based Contingency Management Intervention to Promote Smoking Cessation
Cigarette smoking is the leading preventable cause of death and illness in the United States. Wetested the usability, acceptability, and efficacy of a smartphone-based contingency managementtreatment to promote cessation. We used a nonconcurrent multiple-baseline design. Participants(N = 14) provided breath carbon monoxide (CO) samples by using a CO meter that was con-nected to the user’s smartphone. An app (mMotiv8) housed on participants’ smartphones auto-matically captured pictures of the CO sampling procedure to validate the end user’s identity,and it prompted submissions via a push message delivered to participants’ smartphones. Partici-pants earned a $10 incentive for daily abstinence, which was added to a reloadable debit card.Overall, 4% of the CO samples were negative during baseline, and 89% were negative duringtreatment. Self-reported usability and acceptability were high, and 85% of the prompted sam-ples were submitted. A smartphone intervention could be scalable and reduce the health conse-quences and costs associated with cigarette smoking, particularly in rural and low-incomepopulations
