Measuring attitudes toward injecting drug users and people with hepatitis C.

Preexisting scales used to measure attitudes toward human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and homosexuals were adapted to assess attitudes toward people with hepatitis C (HCV) and injecting drug users (IDUs). In 2005, 110 undergraduate psychology students completed these scales, and abbreviated versions of the IDU and HCV scales were then administered to 61 health care workers to establish their relevance in the field. Results indicated that the new scales have good reliability and validity with undergraduates and with health care workers in an applied setting.
