A COMPARISON OF MULTIPLE INDICATORS - OBSERVATIONS, SUPERVISOR REPORT, AND SELF-REPORT AS MEASURES OF WORKERS HEARING PROTECTION USE

The purpose of this study was to compare multiple indicators of behavi or and identify the most viable measure of blue-collar workers' use of hearing protection. Three measures of use were employed: observations , supervisor report, and self-report. Supervisor report was highly dis crepant from both self-report and observed use; self-report and observ ations were highly correlated, and discrepancies between the two were slight. These results suggest that, for this type of measurement, self -report is an appropriate measure and may be the best choice when time and monetary resources restrict measurement to one indicator.
