Trial Outcomes & Findings for Hippocampal Network Changes Following Mindfulness Training in Tobacco Vaping Adolescents in an Open-label, Pilot Study (NCT NCT06503159)

NCT ID: NCT06503159

Last Updated: 2026-02-27

Results Overview

The change in brain connectivity network from baseline (pre mindfulness-based stress reduction (MBSR) training) to post MBSR functional magnetic resonance imaging (fMRI) brain scan. Analysis will be done as change in brain network connectivity based on pre and post MBSR fMRI scan. Change = post-pre values

Measure
Baseline Group: Non-vapers
Adolescents ages 13-18 years old with no history of nicotine vaping complete structural and resting fMRI of the brain and some questionnaires.
Baseline Group: Vapers
Adolescents ages 13-18 years old with history of nicotine vaping, who vape 4-7 days per week, complete structural and resting fMRI of the brain and some questionnaires.
Intervention: Mindfulness-based Stress Reduction (MBSR) Training
Adolescents ages 13-18 years old with history of nicotine vaping, from the baseline assessment group complete a 9-week intervention once per week in-person or remote mindfulness-based stress reduction (MBSR) training followed by a post-intervention assessment and a second fMRI brain scan.

PRIMARY outcome

Timeframe: Baseline (pre MBSR training) and post-MBSR training (1-6 weeks after MBSR training)

Population: Modified Intention-to-Treat Analysis Dataset. Analysis applies to participants in the MBSR Training group. Participants were not recruited to the interventional phase (MBSR training) due to study termination.

The change in brain connectivity network from baseline (pre mindfulness-based stress reduction (MBSR) training) to post MBSR functional magnetic resonance imaging (fMRI) brain scan. Analysis will be done as change in brain network connectivity based on pre and post MBSR fMRI scan. Change = post-pre values

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Baseline (0-3 months pre-MBSR training) & post MBSR training (up to six weeks after MBSR training)

Population: Modified Intention-to-Treat Analysis Dataset. Analysis applies to participants in the MBSR Training group. Participants were not recruited to the interventional phase (MBSR training) due to study termination.

Participant self-reported change in vaping behaviors will be assessed as reported change in the number of vaping puffs per day at baseline (0-3 months pre-Mindfulness-based stress reduction (MBSR) training) and post MBSR training (up to six weeks after MBSR training). Change = post -pre values

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 9 weeks during the MBSR training

Population: Modified Intention-to-Treat Analysis Dataset. Analysis applies to participants in the MBSR Training group. Participants were not recruited to the interventional phase (MBSR training) due to study termination.

Participant self-reported level of engagement with mindfulness-based stress reduction (MBSR) training will be assessed as percentage of days participant reports practicing MBSR training. Analysis will be done as percentage of days participants practice MBSR training.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 4 months following the MBSR training

Population: Modified Intention-to-Treat Analysis Dataset. Analysis applies to participants in the MBSR Training group. Participants were not recruited to the interventional phase (MBSR training) due to study termination.

Participant self-reported level of engagement with the Craving-to-Quit app, which will be tracked as how much participants reported using the craving to quit app post mindfulness-based stress reduction (MBSR) training. Analysis will be done as percentage of days participants use the app.
