Table 2.

Physician profiles used in choice-based conjoint experiment. “gGvernment” indicates that a public agency provides the ratings, and “Commercial” indicates that a private organization provides the ratings. In the Web-based interface, the hypothetical physician profiles in each pair were shown side-by-side and respondents were asked to choose the physician they prefer. The sequence of the pairs and the attributes in each profile were generated randomly to ensure that the order of the presentation of rank of the attributes did not influence the respondent’s choice. The values of 2 or 4 in the table, respectively, indicate a “2” or “4” star rating in the physician profiles provided to respondents in the Web-based experiment.
