||At last, a book that offers not only an overall perspective of nursing intervention and outcome research but also theory-driven guidelines for future study. Evaluating Nursing Interventions provides clinicians and students alike with a clear explanation of the problems encountered in outcomes and intervention research and then proceeds, via the Intervention Theory, to show how these studies can be undertaken reasonably and comprehensively. The authors first relate outcomes and interventions research to the quality of care. They then review the conventional approach to evaluation and the elements and sources of the Intervention Theory approach to effectiveness research. Characteristics of clients and health care professionals, intervention variables, and outcomes are also considered, concluding with implications for future research in effectiveness. Nurses and other health professionals recognize the need to demonstrate that their care is high quality, effective, and also cost-effective; Evaluating Nursing Interventions helps them evaluate their programs to meet this need.
