Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study involves an emergency department (ED)-based intervention utilizing Motivational Interviewing (MI) techniques and patient-centered eHealth materials (e.g., a tailored, mobile-friendly website and text messages) to promote the correct and consistent use of size-appropriate child passenger restraints (car seats, booster seats, and seat belts). This study is designed as an adaptive randomized controlled trial, recruiting English and Spanish speaking caregivers of children 6 months to 10 years old.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Motor vehicle collisions (MVCs) remain the leading cause of unintentional injury deaths among children in the United States (U.S.) and racial/ethnic minority children are disproportionately impacted as suboptimal child passenger safety behaviors are more prevalent in some communities. Existing universal approaches to promote child passenger safety have fallen short of ensuring that all child passengers are correctly using size-appropriate child passenger restraints according to guidelines published by the American Academy of Pediatrics and the National Highway Traffic Safety Administration. Precision prevention programs are urgently needed to improve child passenger safety behaviors among caregivers who have not been responsive to guidelines, laws, and public education campaigns. The proposed research will test the efficacy of Tiny Cargo, Big Deal/Abróchame Bien, Cuídame Bien (TCBD/ABCB), a bilingual emergency department (ED)-based precision prevention intervention grounded in Self-Determination Theory. TCBD/ABCB integrates personalized counseling based on principles of motivational interviewing (MI) and eHealth components including a tailored educational mobile-friendly website "site" and short message service (SMS) communications with the goal of improving child passenger safety. We hypothesize that by providing tailored child passenger safety education and personalized skills for restraint use in a manner that supports autonomous motivation the TCBD/ABCB intervention will be more efficacious than universal approaches (laws/guidelines) for realizing correct use of size-appropriate child passenger restraints.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

After the baseline survey, all participants will be randomized into one of two groups: 1) basic intervention or 2) control group. Block randomization (block sizes from four to eight) will be applied to assign participants to intervention or control in a 3:1 ratio. Blocks will be stratified by child passenger safety recommendations for age (\<2 years, rear-facing; 2-4 years, forward-facing; 5+ years, booster seat) and reason for study eligibility (not consistently using the recommended restraint for age and size or planning a premature transition in the coming 6 months).

After 6-month follow-up, participants in the intervention group only who continue suboptimal child passenger safety behaviors will be re-randomized in a 1:1 ratio to basic or enhanced intervention.

Primary Study Purpose

TREATMENT

Blinding Strategy

SINGLE

Outcome Assessors

This is a single-blinded study where a portion of the study will include blinding of study team members who are assessing outcomes. The blinding will not include the participants.

The portion of the study that includes blinding is the review of the monthly photo submissions. Participants send us via text message over the course of 12 months. Each photograph is reviewed and scored by two team members. The first reviewer is blinded to study condition and saves the photographs with the child's face blurred. The second reviewer scores the photographs after the child's face has been blurred to verify findings of the first reviewer. The second reviewer is then unblinded to send feedback to the caregiver appropriate for their study condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Enhanced Usual Care

Participants will be randomized after completion of the baseline survey and receive a basic information sheet (print or electronic).

Months 1-12: Participants receive monthly, unscheduled requests to submit photographs as their child usually travels. Feedback is provided for critical errors and misuse. Follow-up occurs at 6 months. Outcomes are assessed at 12 months.

Group Type NO_INTERVENTION

No interventions assigned to this group

Basic Intervention

Participants will be randomized after completion of the baseline survey and receive a basic information sheet (print or electronic). Participants receive a counseling session, access to the study's tailored, educational website, and tailored informational and motivational text messages.

Months 1-6: Participants receive monthly, unscheduled requests to submit photographs as their child usually travels. Feedback is provided. Follow-up occurs at 6 months.

After completion of their 6 month follow-up, participants in the Basic Intervention group will be eligible for re-randomization if they continue to not adhere to guidelines or plan a premature transition.

Months 7-12: Participants continue to receive monthly, unscheduled requests to submit photographs as their child usually travels. Feedback is provided. Outcomes are assessed at 12 months.

Group Type EXPERIMENTAL

Tiny Cargo, Big Deal/Abróchame Bien, Cuídame Bien (TCBD/ABCB) Basic Intervention

Intervention Type BEHAVIORAL

A bilingual emergency department (ED)-based precision prevention intervention grounded in Self-Determination Theory. The Basic TCBD/ABCB intervention integrates one personalized counseling session based on principles of motivational interviewing (MI) and eHealth components including a tailored mobile-friendly educational website and short message service (SMS) text message communications with the goal of improving child passenger safety.

Participants receive monthly text message requests to submit photographs depicting the child as they usually travel. Feedback is provided via text message to correct any observed errors or misuse. Tailored informational and motivational text messages are sent twice each month.

Enhanced Intervention

After completion of their 6 month follow-up, participants re-randomized to Enhanced Intervention receive Basic Intervention components plus an additional counseling session (Months 7/8) and additional tailored text messages (Months 7-12).

Months 7-12: Participants continue to receive monthly, unscheduled requests to submit photographs as their child usually travels. Feedback is provided. Outcomes are assessed at 12 months.
