Brief Summary
The goal of this crossover randomized controlled trial is to develop a proxy reporting protocol for a traditional 24-hour dietary recall (24HR) and an ecological momentary assessment (EMA) assisted 24-HR for use among children between the ages of 2 and 5 years. The main aims are to:
- 1.Assess the usability and feasibility of each proxy-reporting protocol and dietary assessment methodology.
- 2.Describe the dietary misreporting captured using each proxy-reporting protocol, and
- 3.Explore the accuracy of energy intake estimation of the 24HR and EMA+24HR methods, compared to objectively measured food intake.
- 4.Be provided with one meal and two snacks each day to provide to their child on three consecutive days. Foods can be offered to their child at times of their choosing, and leftovers will be placed back into reusable food storage containers to be picked up by research study staff. Uneaten foods will be weighed for an objective measure of intake.
- 5.The day after study-provided foods are given to the child, the adult caregiver will complete a proxy-reported 24HR phone call with a trained research assistant.
- 6.In the EMA+24HR condition, caregivers will be provided access to an online platform where they will upload pre- and post-photographs of all of their child's eating occasions across the three days that study-provided foods are eaten.

Outcome Measures
Primary Outcomes (9)
Usability - EMA+24HR Proxy-Reporting Protocol
Usability of the proxy-reporting protocol for the EMA+24HR condition will be assessed using a self-reported questionnaire. Survey items will focus on adequacy of training and support received, experience communicating with other caregivers regarding what children consumed when they weren't with them, and experience completing the proxy-reported 24HR.
Upon completion of the EMA+24HR condition
Acceptability - EMA+24HR Proxy-Reporting Protocol
Acceptability of the proxy-reporting protocol for the EMA+24HR condition will be assessed using a self-reported questionnaire. Survey items will focus on caregivers' satisfaction with training and support received, their experience communicating with other caregivers regarding what children consumed when they weren't with them, their experience completing the proxy-reported 24HR, and overall satisfaction.
Upon completion of the EMA+24HR condition
Usability of EMA Online Platform
Usability of the online EMA platform will be assessed by comparing the number of pre- and post-photos collected to the self-reported eating occasions captured in the proxy-reported 24HR.
Upon completion of the EMA+24HR condition
Usability - Interface of EMA Platform
The usability of the online EMA interface will be assessed using a self-report questionnaire by using the usefulness and interface quality subscales from the Post-Study System Usability Questionnaire.
Upon completion of the EMA+24HR condition
Acceptability - Online EMA Platform
Four items from the Theoretical Framework of Acceptability (TFA) measure will be used to assess acceptability of the EMA platform, focusing on four constructs 1) affective attitudes, 2) burden, 3) self-efficacy, and 4) general acceptability.
Upon completion of the EMA+24HR condition
Usability - Traditional 24HR Proxy-Reporting Protocol
Usability of proxy-reporting protocols for the traditional 24HR condition will be assessed using a self-reported questionnaire. Survey items will focus on adequacy of training and support received, experience communicating with other caregivers regarding what children consumed when they weren't with them, and experience completing the proxy-reported 24HR.
Upon completion of the traditional 24HR condition
Acceptability - Traditional 24HR Proxy Reporting Protocol
Acceptability of the proxy-reporting protocol for the traditional 24HR condition will be assessed using a self-reported questionnaire. Survey items will focus on caregivers' satisfaction with training and support received, their experience communicating with other caregivers regarding what children consumed when they weren't with them, their experience completing the proxy-reported 24HR, and overall satisfaction.
Upon completion of the traditional 24HR condition
Dietary Misreporting - EMA+24HR Condition
Frequency of dietary misreporting (i.e., time-misreporting, omissions, intrusions, description and amount misreporting) will be assessed in the EMA+24HR by comparison of self-reported dietary assessment to photos uploaded to the EMA platform.
Upon completion of the EMA+24HR condition
Dietary Misreporting - Traditional 24HR Condition
Frequency of omissions will be assessed in the traditional 24HR condition using pre-post food weights to proxy-reported intake from the primary caregiver.
Upon completion of the traditional 24HR condition.

Study Arms (2)
Traditional 24HR
ACTIVE COMPARATORCaregivers will be asked to provide study-provided foods to their child and complete a traditional 24-hour dietary recall using the USDA five-step multiple-pass method.
EMA-Assisted 24HR
EXPERIMENTALIn the EMA+24HR condition, caregivers will receive study-provided foods for one meal and two snacks for three consecutive days. Caregivers will receive information on accessing an online EMA platform, and will be asked to upload pre- and post-photographs of the foods that their child eats over the three days. Additionally, any caregiver with whom the child consumes food outside of the primary proxy reporter will be trained by the primary caregiver and will be given access to upload photographs to the EMA site. The day following consumption of study-provided food, the caregiver will complete a 24HR using the USDA 5-step multiple-pass method by a trained research assistant. The research assistant will have access to all pre- and post-photographs and will prompt the caregiver for misreporting related to the photographs uploaded (i.e., time misreporting, omissions, intrusions, description, and amount misreporting).
Interventions
The EMA platform will allow for the primary caregiver (or any other adult with whom the child eats foods with) to upload pre- and post-photographs of all eating occasions. The photographs will be time-stamped and will be used by trained research assistants during the 24HR to aid in collection of accurate information about what the child consumed. The research assistant will be trained on how to prompt the caregiver for inaccuracies in reporting as needed.
Participants will complete a traditional 24-hour dietary recall via telephone, following the USDA five-step multiple pass method. Participants will receive a standardized food amounts booklet (FAB) to help with quantifying portion sizes consumed.
Eligibility Criteria
You may qualify if:
- Adult caregiver ≥ 18 years old
- Absence of food allergies or dietary restrictions for medical reasons (for the child)
- Caregiver reports child likes at least 70% of the study-provided foods from the pre-defined list of food options
- Caregiver has access to a smartphone device compatible with the EMA platform
- Caregiver can identify a second adult caregiver with access to a smartphone device compatible with the EMA platform and willing to provide the child with study-provided foods for at least two eating occasions.
You may not qualify if:

- Caregiver unwilling to take pre-and-post photos of child's eating occasions
- Caregiver unwilling or unable to identify a second adult caregiver meeting the eligibility criteria
