Competitive employment: assessing employee reactivity to naturalistic observation.

This study assessed the work behavior of five mentally retarded dishwashers. An ABCBC design was utilized with special educators initially observing the dishwashers (Overt measures). During the B phases these educators observed the same dishwashers' work behavior while a second group of observers, posing as kitchen laborers (coworkers), assessed work behavior, during other periods of the day (Overt or Covert). Finally, during C phases, special educators and coworkers recorded dishwashers working at the same time (Overt and Covert). Results indicated dishwashers worked more when educators observed them. Dishwashers spent less time working when these educators were absent. During the "Overt and Covert" observation phases (Phase C), where covert measures were taken in addition to overt measures (i.e., at the same time and on the same person), covert measures covaried with educators' measures of work performance. These results are discussed with suggestions to initiate a program of research to investigate the use of coworkers in the administration of behavior change methods, in work settings.
