The development of the Australian Basic Intensive Care Knowledge Test.
The Basic knowledge Assessment Tool (BKAT), a test developed in the United States, has been presented as a valid and reliable test of basic knowledge for critical care nursing. However, it was necessary to determine the BKAT's validity and reliability in the Australian intensive care (IC) context. The Delphi technique, utilising a panel of eleven experts, was used to determine the content validity of the BKAT. The Delphi process resulted in the development of a test with 105 questions. These questions consist of 49 original BKAT questions, 25 original BKAT questions slightly modified, 3 original BKAT questions with major modifications and 28 new questions. A criterion group design was used to establish the modified test's reliability and decision validity. Item analysis was undertaken using item difficulty and item discrimination indexes. The modified test was completed by 14 registered nurses with no IC experience, 18 registered nurses with intermediate IC experience and 25 registered nurses qualified as intensive care specialists. The mean score (and standard deviation) for the test for each of the respective groups was 41(9), 69(9) and 86(7). These results were significantly different (p < 0001). The reliability was established with a Cronbach Alpha coefficient of .96. The modified test is a reliable and valid measure of IC basic knowledge and can be used as a valuable adjunct in the assessment of IC orientation programs.
