On the Effectiveness of Video Prompting with Embedded Safety Checks to Teach Correct Child Passenger Safety Restraint Installation and Harnessing
Bibliographic record
Abstract
In North America, motor vehicle collisions are the leading cause of unintended injury-related deaths among children under the age of 14. The primary cause of these deaths is the improper use of child passenger safety restraints (CPSR). Correctly installed CPSRs can decrease the risk of fatal injury by 45% to 95%. To date, no studies have used video prompting with embedded safety check to teach correct CPSR installation and harnessing in the absence of researcher implementation. We used a concurrent multiple baseline across participants design to evaluate the effectiveness of a video-prompting procedure with embedded safety checks to teach four prospective parents and caregivers CPSR installation and harnessing skills. All participants learned to perform these skills and these effects maintained for 4 weeks. Further, this training produced an improvement on all participants’ performance of an untrained installation position, vehicle, and harnessing skill, and these effects largely maintained for 4 weeks.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
