Summary
Child safety seat (CSS) instructions are written above the average consumer's reading level. Rewriting CSS manuals at a lower reading level is recommended to improve proper installation and child safety.
Area of Science:
- Pediatrics
- Public Health
- Consumer Safety
Background:
- Proper installation of child safety seats (CSS) is crucial for effective child injury prevention.
- The complexity of CSS installation instructions can be a barrier to correct usage.
- Understanding the readability of CSS instructions is essential for consumer comprehension.
Purpose of the Study:
- To assess the reading level required for understanding child safety seat (CSS) installation instructions.
- To compare the readability of CSS instructions across different price points.
- To determine if lower-cost CSSs, often accessed by low-income families, have simpler instructions.
Main Methods:
- Child safety seat (CSS) installation instructions were collected.
- Readability was assessed using the SMOG (Simple Measure of Gobbledygook) test.
- Interrater reliability was established with a second reviewer.
Main Results:
- The readability of CSS instructions ranged from 7th to 12th-grade levels, with a mean SMOG score of 10.34.
- No significant correlation was found between the price of CSSs and the readability of their instructions.
- This lack of association held true for both continuous and categorical price data.
Conclusions:
- Current child safety seat (CSS) instruction manuals are written at a reading level exceeding that of most American consumers.
- Simplifying the language in CSS instruction manuals is necessary to promote correct installation.
- Improving readability can enhance the effectiveness of child safety seats and reduce injuries.
