Summary
The Employee Safety Inventory reliably measures safety attitudes over time. Test-retest results showed high temporal stability, indicating consistent employee safety attitude assessment.
Area of Science:
- Occupational Health Psychology
- Psychometrics
Background:
- Assessing employee safety attitudes is crucial for workplace safety.
- Reliable measurement tools are essential for accurate attitude assessment.
- The temporal stability of safety attitude inventories requires validation.
Purpose of the Study:
- To evaluate the temporal stability of the Employee Safety Inventory.
- To determine if the inventory provides consistent safety attitude measurements over a short interval.
Main Methods:
- A paper-and-pencil safety attitude inventory was administered to 62 employees.
- Participants completed the inventory twice, with a 10-day interval between administrations.
- Test-retest reliability was calculated using the overall Safety Index.
Main Results:
- A high test-retest reliability coefficient of .88 was achieved for the Safety Index.
- No significant differences in reliability were observed between genders.
- Life events occurring between testings did not impact the inventory's reliability.
Conclusions:
- The Employee Safety Inventory demonstrates strong temporal stability.
- The inventory is a reliable tool for measuring employee safety attitudes.
- Its reliability is consistent across different demographic groups and life event experiences.
