We discovered that two of the items in the knowledge index were incorrectly identified. We reran all the analyses and none of the major findings changed. However, we would like to correct the error since our hope is that others will use the measure. The items in the GKAI are listed below and the correct mean GKAI score is 3.28 (Table 1). The regression analysis (Table 2) shows two indicators, “US born vs. Foreign Born” and “Patient Population: Greater than 20% Minority vs. Less than 20% Minority” changed from highly significant (p = .01) to significant (p = .05). All other significance levels were unchanged. The model fit was also unchanged.

Items in the knowledge index are:

ITEM#

QUESTION

ANSWER

GKAI1

The DNA sequences of two randomly selected healthy individuals of the same sex are 90–95% identical.

False

GKAI2

Most common diseases, such as diabetes and heart disease, are caused by a single gene variant.

False

GKAI4

All the genetic variation in an individual can be attributed to either spontaneous (i.e., de novo) or inherited changes in the human genome.

True

GKAI6

Individual genetic variants are usually highly predictive of the manifestation of common disease.

False

GKAI7

Prevalence of many Mendelian diseases differs by racial groups.
