Accuracy of parental report for specific modes of child restrainst system (CRS) misuse (n=100)
| Correct use | Misuse | |||
|---|---|---|---|---|
| Item assessed | No of seats correctly used | Specificity* (95% confidence interval) (%) | No of seats incorrectly used | Sensitivity* (95% confidence interval) (%) |
| *Specificity reflects the proportion of time that the parent accurately described the selected item when the technician identified it as correctly used. The sensitivity reflects the proportion of time that the parent accurately described the selected item when the technician identified it as misused. | ||||
