Here's a clear, concise, and easy-to-understand approach to nursing research and its impact on the quality of patient care. It provides all of the information necessary for students to understand the components of the research process and to integrate scientific knowledge into their practice to make informed judgments and valid clinical decisions. Each step of the research process is examined in step-by-step detail. The book covers all of the steps of the research process for specific disciplines; develops the skills to evaluate problem and purpose statements critically and analyze the parts of a study to determine the validity of the findings; discusses the specific statistical procedures used to answer various research questions and/or hypotheses; and, examines randomized clinical trials as a methodological 'gold standard' and explains why other types of design are so often necessary in nursing research.
