Out of 5,551 patients seen during a six-month period, 787 patients completed the materials used in the current study for a response rate of 14%. Approximately 55% of the sample were male. The mean age was 41 years (SD 5 10.6). At least 90% of the sample completed high school. Nearly 60% of the sample attended some college. Approximately 49% of the sample held blue collar jobs
WSS items that had a high frequency of nonresponses were dropped from the remaining analysis. The high degree of nonresponse for some items may have indicated that the items were ambiguous or difficult to understand (e.g.,Perilous).
For each of the a priori WSS subscales, corrected item-total correlations ranged from .33 to .78 ( job safety), .49 to .78 (coworker safety),, to all of the self-reported accident variables.
