Micro-randomized pilot trial of an app-based smoking urge reduction intervention for young adults.

ABSTRACT:

Background

Cigarette smoking remains the leading preventable cause of illness and death in the United States and young adults are a priority population. This study aimed to investigate the feasibility of conducting a pilot micro-randomized trial (MRT) among young adults, using smartphone messages to reduce smoking urges in high-risk situations and combining Ecological Momentary Assessments (EMA) and geofence-based delivery.

Methods

Participants were recruited online and completed surveys on Qualtrics and an EMA app to report smoking situations over 14 days (assessment phase).
