The purposes of this methodological psychometric study were to: 1) develop a criterion-referenced instrument to provide effective documentation of knowledge of advanced practice nursing in genetics; 2) determine the validity and reliability of the instrument; 3) compare pass/fail outcomes of nurses within and outside of the genetic specialty using the instrument; 4) compare pass/fail outcomes of Masters’ prepared and non-Masters’ prepared nurses using the instrument; and, 5) compare pass/fail outcomes of credentialed and non-credentialed advanced practice nurses in genetics using the instrument. An additional proposed aim, to evaluate congruence between instrument pass/fail outcomes and Genetic Nursing Credentialing Commission (GNCC) portfolio pass/fail outcomes, was not able to be fulfilled.
The Criterion-Referenced Measurement Tool for Genetics (CRMTG) was found to be valid with a content validity index of .88 and reliable with a Cronbach’s alpha of .99 based on the findings of this study. The CRMTG pass rates indicated a significant difference between nurses who practice in a genetic setting and nurses who do not practice in a genetic setting (p < .001).
