Outcome Variables that Contribute to Group Differences Between Caucasians, African Americans, and Asian Americans who are Deaf
The purpose of this research was to identify those dimensions of outcome variables (i.e., number of VR services provided, cost of case services, income, and number of hours worked at closure) that make the greatest contribution to group differences between Caucasians, African Americans, and Asian Americans who are deaf. Multivariate analysis of variance (MANOVA) and post hoc descriptive discriminant analysis (DDA) were utilized to evaluate 1,108 case records obtained from the RSA-911 database for fiscal year 1997. DDA results indicated that African-Americans were provided with significantly more VR services and achieved significantly lower levels of income when compared to Caucasians and Asian Americans. Results are presented for the discriminating variables and the implications of findings for research and practice are discussed.
