Diana M. Bailey conducted a study to examine the causes for which occupational therapists leave the field of occupational therapy (A-18). The sample consists of certified occupational therapists who left the profession temporarily or permanently. Of 696 individuals who responded to a survey to collect data, 63 percent decided to leave their jobs to dedicate themselves to taking care of their own children. Based on these data, is it possible to conclude that, in general, more than 60 One hundred...
