title: A criterion-referenced measure of latex allergy knowledge.
abstract: The exponential use of latex products has increased patients' and health care workers' sensitization to natural rubber latex. The purpose of this research study was to develop and test a set of items designed to measure professional nurses' knowledge about natural rubber latex reactions and interventions appropriate for latex precautions. The items were developed from research reports in the literature and changed to reflect the suggestions offered by experienced perioperative nurses (pilot = 8) and three nationally known experts in latex allergy responses. The revised form was mailed to the home or distributed at the workplace of perioperative nurses (n = 158). Criteria for item retention were < .90 difficulty index and clinical relevance. Certified nurses (i.e., CNORs) scored significantly higher than other nurses who took the test at the same time (t-test = 2.00, P = .05). A pretest and posttest evaluation of the revised 20 items was conducted before and after a latex allergy continuing education program during the spring of 1998. The current knowledge test (i.e., version 1.1) has reliability (alpha = .80); content validity (CVI = .92); and accumulated evidence of construct validity (preinstruction mean = 14.16, postinstruction mean = 17.15, t-paired = 10.54, df = 70, P = < .001). An empirically developed professional nurse latex allergy competency test suitable for clinical use was the outcome of this research study.
