Test-Retest Reliability of the Genetics and Genomics in Nursing Practice Survey Instrument.

Abstract

Assessment of nursing genomic competency is critical given increasing genomic applications to health care. The study aims were to determine the test-retest reliability of the Genetics and Genomics in Nursing Practice Survey (GGNPS), which measures this competency, and to revise the survey accordingly. Registered nurses (n = 232) working at 2 Magnet-designated hospitals participating in a multiinstitutional genomic competency study completed the GGNPS. Cohen's kappa and weighted kappa were used to measure the agreement of item responses between Time 1 and Time 2. Survey items were revised based on the results. Mean agreement for the instrument was 0.407 (range = 0.150-1.000). Moderate agreement or higher was achieved in 39% of the items. GGNPS test-retest reliability was not optimal, and the instrument was refined based on the study findings. Further testing of the revised instrument is planned to assess the instrument performance.
