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

Background and Purpose: 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. Methods: 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. 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. Conclusions: 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.
