Validity of Scores on the Attitudes toward Diversity Scale (ATDS)

Educational and Psychological Measurement
The Attitudes Toward Diversity scale (ATDS) was developed to measure the construct of attitudes toward diversity. It consists of 10 items representing each of three domains: attitudes toward diversity with regard to (a) coworkers, (b) supervisors, and (c) hiring and promotion decisions. To determine psychometric characteristics of scale scores, 349 full-time workers completed the instrument. Subjects included firefighters, police officers, first-line supervisors, technologists, clerical/secretarial workers, and managers. Confirmatory factor analysis indicates that the ATDS is three-dimensional, as hypothesized. Further analyses suggest that the scale has high internal consistency (a = .90) and is unaffected by a social desirability response style (r = -.09, n.s.).
