Lack of emphasis on the empirical validation of nursing models has hindered the development of nursing science. This article explores issues concerning theory development in nursing and criteria for evaluating theory-testing research. From a comprehensive review of the literature on theory testing, 15 criteria are identified as essential for evaluating theory-testing studies. The criteria are applied to selected research reports, and recommendations for future use of criteria are suggested.
