Study Notes
Research Evidence Appraisal Tool Overview
- Designed for evaluating research evidence in nursing practice.
- Assesses whether evidence addresses a specific Evidence-Based Practice (EBP) question.
Evidence Classification
- Two primary study types: Quantitative and Qualitative.
- Quantitative: Focus on numerical data, statistical analysis, large sample sizes; employs methods like surveys and structured interviews.
- Qualitative: Focus on narrative data, smaller sample sizes; utilizes methods such as focus groups and interviews.
Summary of Research Sources
- Appraisal of multiple sources may require rigorous search and evaluation methods.
- Systematic reviews can either be:
- Composed solely of Randomized Controlled Trials (RCTs) classified as LEVEL I.
- Combination of RCTs and quasi-experimental studies classified as LEVEL II.
- Mixed studies may be classified as LEVEL III.
Appraisal Criteria for Quantitative Research
- Identify known and unknown aspects of the study problem.
- Clear presentation of the study's purpose and relevance.
- Current literature review (preferably sourcing recent studies within five years).
- Adequate sample size based on study design with appropriate rationale.
- Similar characteristics between control and intervention groups, if applicable.
- Clarity in data collection methods is essential.
- Reliability of instruments should have a Cronbach’s alpha greater than 0.70.
- Discussion of instrument validity is necessary.
- Ensure response rate from surveys exceeds 25%.
- Clear presentation of results, maintaining consistency with tabulated data.
- Identification and discussion of study limitations are critical for comprehensive appraisal.
