Study summary

The purpose of this study is to develop and evaluate an evidence-based intervention to assist adolescents and young adults with current vaping to quit vaping and smoking.

Read the detailed description

Use of electronic nicotine delivery system (ENDS), which are noncombustible tobacco products (e.g., e-cigarettes), has increased dramatically among youth and is associated with numerous adverse health outcomes as well as use of alcohol and other illicit substances. National guidelines recommend counseling to address tobacco use at every adolescent clinical visit; however, many at-risk adolescents do not routinely attend primary care. Although evidence supports treatment of tobacco use during an adult hospitalization, no interventions have been developed or tested in the pediatric hospital setting. Based on promising theoretically-based evidence from the primary care and hospital settings, we will design, iteratively refine and assess implementation of a novel tobacco and ENDS use intervention for hospitalized adolescents and young adults (AYAs). We do so by conducting a randomized controlled pilot study (n=144) with 3-month follow up to evaluate preliminary efficacy as well as implementation outcomes (i.e., acceptability, feasibility, fidelity).

What researchers measure

Primary outcomes

  1. Self-reported 30-day Abstinence

    Self reported cessation, assessed at 3 month follow up survey.

    Time frame: 3 month follow-up

  2. Biochemically Verification of Past 30 Day Cessation

    For participants who self-reported past 30 day cessation, an option was provided to biochemically verify cessation with a mailed saliva sample.

    Time frame: 3 month follow-up

Secondary outcomes

  1. Acceptability of Intervention - Satisfaction and Likeliness to Recommend Program

    Ratings from participants on perceived acceptability (i.e., satisfaction and usefulness) of the intervention

    Time frame: Study completion (approximately 12 weeks)

  2. Acceptability of Intervention - Utility of Intervention

    Acceptability of the intervention assessed by intervention element completion rates (i.e. overall uptake of support resources).

    Time frame: Study completion (approximately 12 weeks)

  3. Feasibility of Intervention - Duration of Intervention

    Assessment of the feasibility of the intervention based on information about delivery gathered from the computerized decision making system (CDS) such as the duration of the intervention.

    Time frame: Study completion (approximately 12 weeks)

  4. Feasibility of Intervention - Intervention Interruptions

    Assessment of the feasibility of the intervention based on information about delivery gathered from the computerized decision making system (CDS) such as the number of interruptions (by clinical staff, parents, or others) that occurred during intervention delivery.

    Time frame: Study completion (approximately 12 weeks)

  5. Feasibility of Intervention - Health Educator Survey

    Feasibility of the intervention as assessed by the health educator who delivered the intervention.

    Time frame: Study completion (approximately 12 weeks)

  6. Fidelity of Intervention Delivered by a Health Educator

    Extent of fidelity achieved in intervention delivery by a health educator. The mean score was calculated from 0 (never/very poor) to 5 (always/very good) for each of the 10 fidelity rating questions, which were summed, with a maximum possible score of 50. The scale utilized was an adapted version of the Motivational Interviewing Treatment Integrity tool (MITI).

    Time frame: Study completion (approximately 12 weeks)

Results

Posted Feb 9, 2026
Limitations and caveats
We enrolled e-cigarette users at any stage of motivation to quit, which may have impacted intervention efficacy. Due to practical limitations participants and the research team were not blinded to study conditions which may have led to bias in the assessment of outcome. We relied on self-report which is susceptible to social desirability bias and had very low biochemical verification completion rates to confirm our primary outcome. As a single site study there is limited generalizability.
