A total of 36 student volunteers who were enrolled in a rehabilitation graduate course were randomly assigned to one of two groups to test the effect of completing an attitude scale in the presence of other people, as opposed to completing it alone. A pretest-posttest control-group design was used, and a 30-day follow-up was conducted. Results of a two-way analysis of variance with one repeated measure revealed a significant trials effect for the concept “persons who are blind” (p < .05). In addition, a significant interaction for the concept “communicating with handicapped people” (p < .05) was revealed.
