The authors constructed and validated an instrument that assesses attitudes toward the Americans With Disabilities Act (ADA), a law that protects the civil rights of individuals with disabilities. The Disability Rights Attitude Scale (DRAS) demonstrated acceptable reliability and validity with 2 samples of university students (N = 421). Reliability analysis resulted in Cronbach's alphas of .91 (Sample 1) and .90 (Sample 2). Principal-components factor analysis indicated that the DRAS essentially consists of 1 factor that accounted for 27% (Sample 1) and 31% (Sample 2) of the total variance. Construct validity analysis resulted in predicted, significant positive correlations with other relevant measures. A stepwise multiple regression analysis revealed that sex, ethnicity, and prior contact with people with disabilities were significant predictors of attitudes toward the law. The DRAS provides a psychometrically sound means of assessing attitudes toward disability rights that may encourage or impede implementation of the ADA.
