Nursing Research: Methods and Critical Appraisal for Evidence-Based Practice-

Nursing Research: Methods and Critical Appraisal for Evidence-Based Practice- Research - ANS Systematic investigation about phenomena Qualitative - ANS Studies conducted to understand the meaning of human experience Meta Analysis - ANS Statistical technique used to summarize studies in a systemic review Critique - ANS Critically evaluates a research reports content based on a set of criteria to evaluate the scientific merit for application to practice Quantitative - ANS Studies conducted to test relationships, assess differences, and/ or explain cause and effect Systematic Review - ANS Summary and assessment of a group that considered similar research questions Evidence Based Practice - ANS Clinical practice based on the collection, evaluation, and integration of clinical expertise, research evidence, and patient preferences Clinical Guidelines - ANS Systemically developed statement that provide recommendations to guide practice Quality Improvement - ANS Systematic use of data to monitor outcomes of care Abstract - ANS Brief summary of a study found at the beginning of an article Integrative Review - ANS Review and synthesis that may include qualitative and quantitative articles in a focused area Evidence Base Guidelines - ANS Guidelines develop using published research findings Meta Synthesis - ANS Synthesis of qualitative research studies on a focused topic using specific qualitative methodology Consensus Guidelines - ANS Expert base guidelines, developed by agreement of experts in a field Levels of Evidence - ANS Rating system or hierarchy for assessing the relative worth of qualitative and quantitative studies Critical Reading - ANS Skills in evaluating the appropriateness of the content of a research article, applying standards or critiquing criteria to assess the study's scientific merit for use in practice, or considering alternative ways of handling the same topic Critical Appraisal - ANS Evaluating the strengths and weaknesses of a research article for scientific merit and application to practice, theory, education, or needing more research The first step in development of an evidence-based practice project. - ANS clinical question In experimental studies, the presumed effect of the independent or experimental variable on the outcome. - ANS dependent variable Hypothesis that specifies the expected direction of the relationship between the independent and dependent variables. - ANS directional hypothesis A prediction about the relationship between two or more variables. - ANS hypothesis The antecedent or the variable that has the presumed effect on the dependent variable. - ANS independent variable Indicates the existence of a relationship between the variables but does not specify the anticipated direction of the relationship. - ANS non-directional hypothesis A well-defined set that has certain specified properties. - ANS population That which encompasses the aims or objectives the investigator hopes to achieve with the research, not the question to be answered. - ANS purpose A statement about the expected relationship between the variables; also known as a scientific hypothesis. - ANS research hypothesis A key preliminary step wherein the foundation for a study is developed from the research problem and results in the research hypothesis. - ANS research question States that there is no relationship between the independent and dependent variables. The statistical hypothesis also is known as the null hypothesis. - ANS statistical hypothesis
