ASPD Research Methods and Evidence 1 — Questions and Answers
Question 1: What are the three components of evidence-based practice?
- Best available evidence, clinical expertise, and client values (Correct answer)
- Research data, administrative policy, and cost analysis
- Clinical trials, staff preferences, and facility guidelines
- Academic literature, government mandates, and insurance requirements
Correct answer: Best available evidence, clinical expertise, and client values
Evidence-based practice integrates the best available research evidence with clinical expertise and patient preferences.
Question 2: Which level of evidence is generally considered the strongest?
- Systematic reviews and meta-analyses of randomized controlled trials (Correct answer)
- Single case studies
- Expert opinion
- Anecdotal reports
Correct answer: Systematic reviews and meta-analyses of randomized controlled trials
Systematic reviews and meta-analyses synthesize findings from multiple high-quality studies, providing the most reliable evidence.
Question 3: What is a randomized controlled trial (RCT)?
- A study where participants are randomly assigned to treatment or control groups (Correct answer)
- Any study published in a medical journal
- A trial that tests multiple drugs simultaneously
- A study conducted only in laboratory settings
Correct answer: A study where participants are randomly assigned to treatment or control groups
RCTs randomly assign participants to groups, minimizing bias and allowing researchers to determine cause-and-effect relationships.
Question 4: Why is critical appraisal of research important?
- To evaluate the quality, validity, and applicability of study findings (Correct answer)
- To find reasons to reject all research
- To confirm pre-existing beliefs
- To simplify complex statistics
Correct answer: To evaluate the quality, validity, and applicability of study findings
Critical appraisal helps determine whether research findings are trustworthy and relevant to specific practice situations.
Question 5: What does the PICO framework help formulate?
- A focused clinical question for literature searching (Correct answer)
- A patient discharge summary
- A quality improvement action plan
- A budget proposal
Correct answer: A focused clinical question for literature searching
PICO (Patient/Population, Intervention, Comparison, Outcome) structures clinical questions to facilitate effective literature searches.
Question 6: How should conflicting evidence be handled in practice decisions?
- Weigh the quality of studies and consider the totality of evidence (Correct answer)
- Always follow the most recent study regardless of quality
- Disregard all evidence and rely on experience only
- Choose the evidence that supports current practice
Correct answer: Weigh the quality of studies and consider the totality of evidence
When evidence conflicts, practitioners should evaluate study quality, consider all available evidence, and apply clinical judgment.
