Patient attitudes toward their health care providers can play an important role in determining health behavior change. The frequency of contact with health care professionals and disease stigma makes assessing patients' perception of this relationship of particular interest in an HIV medical population. While past general satisfaction and attitude tools have been used to assess this construct, there is a need for an assessment tool specific to patient attitudes in an HIV setting. This study was designed to validate the Attitudes toward HIV Health Care Provider scale (AHHCP) in an HIV medical population. Principal components analysis of the AHHCP yielded a two-factor structure accounting for 53.3% of the total variance in attitudes toward health care providers. The two factors represented items concerning Professionalism and Emotional Support. The AHHCP was found to have good internal consistency (0.92) and convergent validity with a measure of patient satisfaction (r = 0.59). The results of the present study suggest that the AHHCP is a reliable and valid instrument for use in assessing patient attitudes toward their health care providers.
