Summary

This study will develop an ecological momentary implementation intentions intervention (EMI-II) for cigarette smoking, which will link critical situations where smoking is likely to occur with alternative responses to support avoidance of cigarette use. Using ecological momentary assessment (EMA) for data collection, this project will evaluate the feasibility, acceptability, and initial effectiveness of a micro-randomized trial (MRT) of EMI-II targeting cigarette smoking reduction in a sample of adults who smoke a minimum of 15 cigarettes per day (n=100).

Interventions

BEHAVIORAL

Ecological Momentary Implementation Intentions Intervention (EMI-II)

To reduce smoking, this text messaging intervention will use a self-regulatory strategy, Implementation Intentions (II) to deliver appropriate alternative responses to cigarette smoking. Participants will create personalized II messages before starting the two-week intervention period. Then during the intervention period, after receiving Ecological Momentary Assessments (EMAs), participants will be micro-randomized to receive the EMI-II. During the EMA + EMI-II period, participants will complete five daily EMAs. After approximately 40% of these EMAs, participants will also receive the personalized EMI-II by text messaging.
