Study Summary

This trial aims to compare the efficacy of CBT and mindfulness/ACT interventions to help young adults quit smoking in real-time.

Who is the study for?

This trial is for young adults in the U.S., aged 18-30, who can read English and want to quit smoking. They must have smoked over 100 cigarettes in their lifetime and currently smoke at least once on three days each week. Participants need to own a smartphone and plan to quit within the next month.Check my eligibility

What is being tested?

The study tests if messages sent through smartphones using cognitive behavioral therapy (CBT) or Mindfulness/Acceptance and Commitment Therapy (ACT) help young adults stop smoking. It focuses on sending support during high-risk situations that trigger the urge to smoke.See study design

What are the potential side effects?

Since this intervention involves only messaging support without any medication, there are no direct physical side effects expected from participating in this trial.

Experimental Treatment

Active Control

Group I: Micro-randomized trial groupExperimental Treatment1 Intervention

The micro-randomized trial will determine if CBT and Mindfulness/ACT messages are superior to control messages in reducing the primary outcome momentary smoking urges. Based on participants' training data collected in the initial 14 days of EMA monitoring, intervention messages will be delivered during time-periods and at high-risk locations for smoking. In the intervention phase, participants will be prompted to complete 3 geofence-triggered EMAs per day for a total of 30 days. Each EMA will be followed by an intervention message and the type of message (CBT, Mindfulness/ACT, control) will be randomly selected at each time point (within-subject randomization).

Group II: EMA-only control groupActive Control1 Intervention

A total of N=80 participants will be randomized into an EMA-only control group, parallel to the micro-randomized trial intervention group. This group will conduct 14-day EMA only training phase just like the micro-randomized trial group, but will not be switched over to the intervention phase after these initial 14 days. Instead, participants will continue the EMA-only data collection procedure for an additional 30-days (analogous to the 30-day intervention phase of the micro-randomized trial). During these 30 days, the EMA-only control group will continue to receive 3 randomly prompted EMA surveys per day and an additional 3 EMA surveys triggered by smoking reports.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is the age restriction for this trial limited to those over 40 years old?

"As indicated by the inclusion criteria of this research project, only individuals aged between 18 and 30 may participate."

Answered by AI

Is participation in this clinical experiment open to me?

"The prerequisites to enter this clinical trial are that the participant has a history of smoking and is between 18-30 years old. At present, 160 people have been sought out for recruitment."

Answered by AI

What goals is this medical experiment hoping to accomplish?

"This clinical trial will measure its success by assessing changes in cigarette consumption, other tobacco product use, stress levels, and negative affect over a period of 15 minutes after message delivery. The single-item assessments are binary yes/no responses for the first two items while the last three outcomes utilize 5 point scales ranging from very low to very high."

Answered by AI

Are there any open recruitment slots for this experimental research?

"According to information presented on clinicaltrials.gov, this research initiative is no longer recruiting patients after being initially posted in May of 2023 and last updated 18th April of the same year. Nevertheless, there are other medical studies that still accept applicants at this moment."
