Detailed Description

This study is a randomized controlled trial of a social media intervention to support teens in their efforts to quit vaping.

Interventions

  • Behavioral: Social Media Intervention
    • Social media based intervention using Instagram with up to 3 posts per day for 30 days

Arms, Groups and Cohorts

  • Experimental: Vaping Intervention
    • The vaping intervention will be implemented on Instagram. Participants in the treatment condition will be assigned to groups on Instagram, where they will receive up to 3 posts per day for 30 days. Groups are facilitated by a trained Guide, working with the Principal Investigator, Co-Investigators and a Pediatrician on demand if additional expertise or clinical advice is needed. Participants will be educated about signs of nicotine dependence and if they express interest in pharmacotherapy will be encouraged to access this through their personal healthcare providers. The Instagram groups will provide educational and social support, troubleshooting and advice about NRT or other forms of treatment.
  • No Intervention: Control Condition
    • Participants in the control condition will be directed to the Truth Initiative e-cigarette texting quit program. This innovative and free text message program was created with input from teens, college students and young adults who have attempted to, or successfully, quit e-cigarettes using text coaching methods

Clinical Trial Outcome Measures

Primary Measures

  • Point Prevalent Abstinence (PPA) from vaping
    • Time Frame: 1 month
    • 7-day point prevalence abstinence (PPA) from all tobacco products will be assessed over the course of the study. Participants reporting no vaping in the past 7 days will be coded as abstinent. Those reporting 7-day abstinence and not using nicotine replacement therapy will be mailed saliva cotinine test kit and saliva tetrahydrocannabinol (THC) test kit for biochemical verification of abstinence.
  • Point Prevalent Abstinence (PPA) from vaping
    • Time Frame: 3 months
    • 7-day point prevalence abstinence (PPA) from all tobacco products will be assessed over the course of the study. Participants reporting no vaping in the past 7 days will be coded as abstinent. Those reporting 7-day abstinence and not using nicotine replacement therapy will be mailed saliva cotinine test kit and saliva tetrahydrocannabinol (THC) test kit for biochemical verification of abstinence.
  • Point Prevalent Abstinence (PPA) from vaping
    • Time Frame: 6 months
    • 7-day point prevalence abstinence (PPA) from all tobacco products will be assessed over the course of the study. Participants reporting no vaping in the past 7 days will be coded as abstinent. Those reporting 7-day abstinence and not using nicotine replacement therapy will be mailed saliva cotinine test kit and saliva tetrahydrocannabinol (THC) test kit for biochemical verification of abstinence.

Secondary Measures

  • Change in the number of participants with reduction in vaping
    • Time Frame: Up to 6 months
    • Reduction in vaping is defined as a decline in vaping frequency by 50% or more.
  • Change in the number of vape quit attempts
    • Time Frame: Up to 6 months
    • The number of quit attempts will be recorded at each assessment.
  • Number of participants with at least 1 quit attempt
    • Time Frame: Up to 6 months
    • The number of participants whom achieved at least one quit attempt during the full assessment time period will be reported.
  • Change in response on Stages of Change Questionnaire
    • Time Frame: Up to 6 months
    • The participants readiness to quit will be measured using the Stages of Change questionnaire – single item, which asks “Are you seriously thinking of quitting smoking?” Answers range from ‘Yes, within the next 30 days’, ‘Yes, within the next 6 months’, and ‘No, not thinking of quitting’.
  • Change in the score on the Thoughts About Abstinence (TAA) Questionnaire
    • Time Frame: Up to 6 months
    • The adapted Thoughts About Abstinence Questionnaire (Hall et al., 1991) is a 3 item self-report questionnaire that measures: 1) desire to quit smoking, 2) expected success at quitting, 3) expected difficulty of quitting on 10-point Likert scales (e.g., 1=no desire to quit/lowest expectation/lowest level of difficulty to 10 = extreme desire to quit/highest expectation of success/highest expected difficulty)
  • Change in the scores on the Ways of Quitting questionnaire (WOQ)
    • Time Frame: Up to 6 months
    • The WOQ is a 28-item self-report instrument assessing adolescent smoking cessation strategies. For each WOQ item, respondents indicate whether they have used a given strategy (yes/no) and, if used, how helpful it was perceived to be on a five-point Likert-type scale (1= “Not helpful” to 5=”Extremely helpful”) with regard to several categories: Social support, Seeking assistance, Avoidance, Reduction, Substitution, Medication, Distraction, and Quit all at once (single item).
