Phase II - Modular Convertible Child Safety Seat to Improve Usage
Minnesota HealthSolutions
Summary
Child car safety seats (or "car seats") are an important tool to keep children safe in motor vehicle crashes, but are often misused by parents and caregivers. The installation of car seats can be time consuming and confusing. A new type of swivel car seat is being developed to potentially alleviate some of the typical frustrations that might lead to car seat misuse, specifically the visibility and usage of the top tether feature. This study aims to evaluate the new car seat product and determine whether the new design results in fewer installation errors compared to a traditional car seat. Primary objective: To compare the number of top tether installation errors produced with a production-ready prototype swivel child safety seat vs. a traditional (control) seat. Secondary objective: To assess self-reported preference and opinions on the swivel child safety seat design.
Description
Background: A preliminary Phase I study has already been conducted, in which volunteer focus groups provided qualitative feedback on a new prototype design. For this Phase II study, the revised prototype will be quantitatively and qualitatively evaluated by a larger sample of volunteers. Volunteer adult participants will be asked to complete two car seat installations: one with the new swivel prototype, and one with a traditional control car seat. Basic instruction manuals will be provided. The types and frequency of installation errors for each car seat will be quantified, and qualitative fee…

The participant will be asked to install two different child safety seats into a vehicle, presented to the participant one at a time (random order). The researcher will explain that the participant should install each seat to the best of his/her ability and may take as long as needed. When each installation is completed, the participant will be led away from the vehicle while their work is evaluated by a study-team approved researcher who is a certified Child Passenger Safety Technician (CPST). A data collection form will be used to document any installation errors. Following the installations, participants will complete a short survey with open-ended queries to describe facilitators or barriers they experienced while installing the seats, as well as what they liked or did not like about each seat. They will use a Likert scale to rate their self-efficacy in installing the seats, if they believed they were installed correctly, general ease-of-use, and which seat they preferred.
