Figure 1. Surgeon Attitudes About Genetic Testing and Counseling.

A-G, The Tendency to Test Scale, a scale developed by the authors, was constructed from 7 survey items. The correlations with the overall surgeon Tendency to Test Scale reported on each panel provide some quantification of how each item contributes to the scale score, which represents the tendency to order genetic testing. H, The scale distribution from −2 (strongest tendency against testing) to 2 (strongest tendency for testing) is shown based on the item response model using the 7 items. The mean (SD) scale score was near zero at 0.3 (0.8).
