About this study

Among the 15 million people with food allergies in the U.S., adolescents experience the highest risk of adverse events. Yet, there are few evidence-based strategies to improve food allergy management in adolescents. In a cohort multiple randomized controlled trial, this study will include two experiments to test the effectiveness of text message reminders and incentives to encourage epinephrine-carrying.

Read the detailed description

Among the 15 million people with food allergies in the United States, adolescents experience the highest risk of adverse events, including death from anaphylaxis. Visits to one pediatric emergency department for anaphylaxis doubled between 2001 and 2006, suggesting a rapidly escalating public health burden. Despite this critical concern, there are few evidence-based strategies to improve food allergy management in adolescents, who must sustain three core prevention strategies: diligent avoidance of allergenic foods, consistent carrying of potentially life-saving epinephrine auto-injectors, and prompt administration of epinephrine in the event of anaphylaxis.

The objective of this study is to develop and test interventions to encourage safer food allergy management among adolescents. The primary outcome is consistency of epinephrine-carrying, measured using cell phone photographs at randomly-timed check-ins. This study will be among the first to longitudinally track normative food allergy management practices and one of the first to test behavior change strategies.

In a cohort multiple randomized controlled trial (n=130), the study will include two experiments to test the effectiveness of text message reminders and incentives, using various incentive designs that have proven effective in prior behavioral economics interventions to encourage weight loss and smoking cessation. Aim 1. Test the impact of a text-message reminder system on consistency of epinephrine carrying. Aim 2. Test the impact of modest incentives on consistency of epinephrine carrying. Based on promising preliminary data, the central hypothesis is that, compared to controls, adolescents who receive text message reminders plus modest financial incentives will more consistently carry their epinephrine.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Text Message OnlyBehavioural

    The intervention group (n=25, randomly selected from the base cohort) will receive informational and socially supportive text messages during a 10-week intervention. Investigators will deploy the intervention using the Way to Health platform, which automates outgoing messages and feedback. Many of the messages will be sent to all Intervention 1 participants, to assure consistency of the intervention. A subset will be tailored to address participants' specific allergies. At 10 unannounced check-ins, we will send text messages asking participants in the intervention and control groups if they are carrying their epinephrine.

  • Text message + Incentive 1Behavioural

    Among base cohort members not exposed to the text message only intervention (#1), we will randomly select a new intervention group (n=50) to receive text message reminders plus Incentive 1. At each of 10 unannounced check-ins, if unsuccessful in documenting epinephrine-carrying, participants will lose part of their incentive. The remainder of the Cohort (control) will receive text reminders.

CohortNo interventionFor the cohort multiple randomized controlled trial (cmRCT), investigators will recruit 130 participants (the base cohort) ages 15-19. The base cohort allows investigators to measure normative food allergy self-management practices, while also serving as a control for experiments in Interventions 1 and 2.
ControlNo interventionThe baseline cohort serves as the control group in this cmRCT. Participants will not receive text message reminders (during Intervention 1) or incentives (during Intervention 2). However, they will participate in all data collection points, including text message check-ins to assess epinephrine-carrying. Participants in the base cohort will receive usual care.
Adolescent Allergy AdvisorsNo interventionWe will pilot the text messages to be used in Interventions 1 and 2 through interviews and cognitive testing among 20 Adolescent Allergy Advisors, who will critique message content, framing, and language. These advisors will not be part of the cohort multiple randomized controlled trial.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of check-ins at which participant is carrying epinephrine auto-injector

    Proportion of check-ins at which participant is carrying epinephrine auto-injector, measured using cell phone photographs

    Measured: 10 randomly timed check-ins during the 10-week intervention period

Secondary outcomes (3)
  1. Characterize adolescents' normative food allergy management practices

    Characterize adolescents' normative food allergy management practices, measured comparing baseline and follow-up surveys that assess social challenges, out-of-home eating, allergen avoidance, and response to adverse events.

    Measured: Year-long cohort study

  2. Characterize adolescents' normative food allergy management practices

    Characterize adolescents' normative food allergy management practices, measured using periodic text-message questions that assess social challenges, out-of-home eating, allergen avoidance, and response to adverse events.

    Measured: Year-long cohort study

  3. Develop a set of text message reminders to promote safer food allergy management among adolescents

    Develop a set of text message reminders to promote safer food allergy management among adolescents by cognitively testing text message content

    Measured: 2-year project period

Questions about this trial

What is this clinical trial studying?

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of check-ins at which participant is carrying epinephrine auto-injector (time frame: 10 randomly timed check-ins during the 10-week intervention period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03284372, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2021.
