Psychometric Analysis and Revision of the Opinions Relative to Mainstreaming Scale

This article provides supporting evidence for the use of a revised version of the Opinions Relative to Mainstreaming (ORM) scale. Analyses of data produced by a test of the revised scale, the Opinions Relative to Integration of Students with Disabilities (ORI), indicated satisfactory item characteristics and adequate reliability and homogeneity. Initial support for ORI's construct validity was demonstrated by the results of regression analyses relating ORI scores to respondent sociodemographic and experiential data and scores on the Scale of Attitudes Toward Disabled Persons (SADP). The ORI should prove useful to researchers evaluating the attitudes of educators toward the integration of students with disabilities into general education classrooms.
