To ascertain whether any physician characteristics were associated with the average scores, we calculated two sets of correlations. The average scores for both genetic diseases (ie, untreatable and treatable) were correlated with the following physician characteristics: sex (0, man; 1, woman), age (y), European American ethnicity (0, no; 1, yes), Catholic religious affiliation (0, no; 1, yes), parental status (0, no; 1, yes), and years in practice (scores given for ea variable?<16 y, >16 y). The correlations of the average scores for an untreatable genetic disease with physician sex, age, European American ethnicity, being Catholic, being a parent, and years of practice were –0.20, 0.16, 0.15, 0.04, 0.18, and –0.13, respectively. The correlations of these variables with the average rating for a treatable disease were, respectively, –0.10, 0.07, –0.15, 0.11, 0.01, and 0.10. None of the correlations is significant beyond the .05 level (two-tailed test) after applying a Bonferroni adjustment of .05 to control for the six correlations. Therefore, we concluded that none of the physician characteristics needed to be controlled for in subsequent analyses.
