The purpose of this study was to determine the impact of a genomic educational session by measuring participants' application of the class content to their nursing care. A sample of 65 psychiatric nurses participated in a staff development activity and completed a survey. Every respondent reported use of a genomic assessment or intervention with a patient from their clinical practice. The mean use of genomic assessment and intervention items was 5.5 out of the possible 10 which were identified and described in the educational session, providing evidence that nurses are able to include genomic assessments and interventions when caring for a patient with a psychiatric disorder.
