The primary aim of the FAK intervention is to increase the young child's understanding of FAs including prevalence, symptoms, and management strategies among other topics. We will achieve this aim through the use of educational materials targeting knowledge acquisition through a variety of didactic materials made freely available through the Food Allergy Research Education (FARE) website (www.foodallergy.org). More specifically, we will employ information embedded within the "Food Allergy 101" segment of the FARE website. The young child and their parent/caregiver will be present for the entirety of all sessions; however, all intervention materials are designed with the young child as the primary focal point of interest. All children will be rewarded with a small toy (<$5 value) at the end of each successfully completed session. All FAK sessions will occur within the child's home and will include informational handouts relevant to the day's session.

The FAQL-PB is designed to assess the health-related quality of life among parents of children, 0-12 years of age, with a food allergy. Higher scores indicate greater perceived burden. The scale has demonstrated excellent internal consistency and temporal stability and good construct validity. This outcome measure is a change score (end of treatment minus baseline) with higher scores representing greater improvement in quality of life.

The FAMAS is a semi-structured interviewed designed to assess variety of domains related to a family's psychosocial adjustment to a child's food allergy. The interview includes a myriad of subscales related to this broader construct including food allergy knowledge, medication availability, symptoms of food allergy, child and family food avoidance, family and child response readiness, and parent and child anxiety among other domains. Evidence suggests that the FAMAS demonstrates excellent inter-rater reliability and strong construct validity. Higher scores indicate greater overall (better) food allergy management. The outcome measure is a change score with higher scores representing greater change in a family's food allergy management.

The FAIS is a 32-item scale designed to measure the impact of a child's food allergies on day-to-day activities within the home including meal preparation, social activities, etc. Higher scores indicate increasing level of impact on family functioning. Prior research suggests that the FAIS demonstrates adequate internal consistency. Outcome measures represents a change score (i.e., final assessment - initial assessment) with smaller (negative) scores indicating a reduction in the impact of food allergy on the family.

Participants enrolled in this arm of the study received 5, 20 minutes educational virtual training sessions designed to increase knowledge pertaining to food allergies. All sessions occurred virtually at the child's home.

Food Allergy Knowledge Intervention: The primary aim of the FAK intervention was to increase the young child's understanding of FAs including prevalence, symptoms, and management strategies among other topics.

Total of all reporting groups

The FAKT is a 39 question, parent-report measure designed to assess knowledge about food allergies across five domains: General clinical food allergy knowledge, avoiding exposure, epinephrine auto-injector, anaphylaxis, and symptoms. Questions are multiple choice, true/false, or multiple-item (i.e., indicate whether each item is a symptom of a food allergy) formats. The scale yields a total of 59 items that can be scored with possible scores ranging from 0 to 59. Higher scores indicate a great degree of food allergy knowledge. This scale demonstrates strong psychometric properties.

Designed to provide an objective measure of a child's behavior to an unknown food-item in the real world. Modeled after similar methodology employed in prior skills training research. Child's response coded (see Research Strategy), based upon video assessment. Higher scores (ranging from 0 to 4) indicate greater adherence. Baseline data represent pre-intervention score.

Due to an error in data collection, data from one participant was missing.

Designed to present a young child with a hypothetical scenario in which they might come into contact with a novel food item. The child's response is coded (see Research Strategy), based upon videotaped assessment made possible via a camera placed in the room. Higher scores (ranging from 0 to 4) indicate greater adherence. Baseline scores represent data from the pre-intervention assessment.

Due to an error in data collection, data is missing from one participant.

The role-play assessment will occur immediately following the in situ assessment and is modeled upon similar methodology employed in prior skills training research. The study independent evaluator verbally presents the young child with a hypothetical scenario. For example, "Let's pretend that you are in your living room and your mom asks you to pick up your toys. While you are picking up your toys, you find candy. What would you do?" The IE will design each scenario so that the physical layout of the room permits the child to exhibit behavior congruent with the described situation. The child?s response will be coded (see Research Strategy), based upon videotaped assessment made possible via a camera placed in the room. Higher scores (ranging from 0 to 3) indicate greater adherence. Inter-rater reliability will be obtained on 30% of role-play food assessments.Scores represent change from pre-intervention to one-month follow-up assessment.

Data missing/Data collection error. In total, three participants were randomized to an intervention condition. One participant did not attend their post-intervention assessment; thus, no data are available for said participant. The remaining two participants data are missing due to video not being uploaded properly; thus, no data are available for the two remaining participants.

The child-report food assessment will occur immediately following the role-play assessment. The study IE presents a scenario in which a child finds a food-item (e.g., playing at a friend's home). The independent evaluator will ask the child to state what he/she would do, if that situation happened to them. The child's response will be coded (see Research Strategy), based upon videotaped assessment made possible via a camera placed in the room. Higher scores (ranging from 0 to 3) indicate greater adherence. Inter-rater reliability will be obtained on 30% of child-report food assessments.

Higher scores indicate a great degree of food allergy knowledge. The scale demonstrates strong internal consistency and construct validity with criterion measures of parent educational status, access to food allergy information, insurance status, and epinephrine use. The FAKT will be used as a process measure designed to ensure that basic educational material is received. This outcome measure is a change score (end of treatment minus baseline) with higher scores representing greater improvement in food allergy knowledge.

Data missing/Data collection error. In total, three participants were randomized to an intervention condition. One participant did not attend their post-intervention assessment; thus, no data are available for said participant. The remaining two participants data are missing due to the participants either not responding to (or receiving) the post-intervention survey link; thus, no data are available for the two remaining participants.

The CBCL is a 112-item parent-report scale assessing child symptoms across several domains including social skills, school functioning, and emotional and behavioral problems. Prior research utilizing the CBCL demonstrates strong reliability and validity amongst youth populations. Although multiple versions of the CBCL exist, we will employ the parent-report (6-18 year old) version. For the purposes of the proposed study, we will employ the CBCL as a post hoc measure to assess potential predictors of intervention response. Higher scores on CBCL subscales indicate a greater presence of corresponding behavioral symptoms.
