A validation of the Worker Trait Groups in the DOT

An empirical validation of the 114 Worker Trait Groups (WTG) of the Third Edition of the Dictionary of Occupational Titles (DOT) was performed by comparing the factor structure of the worker trait components of the 114 WTG's with the factor structure of a random sample of 800 of the 4000 jobs used as the basis for the DOT, Third Edition. Six factors were compared and cosines between .8997 and .9657 obtained on the matched factors, thus providing a measure of empirical validity for the 114 WTG's based on the worker trait components.
