Ebp 1: Essential Ebp Evidence Literacy
Explore the essentials of evidence-based practice (EBP) in this quiz, focusing on formulating clinical questions, understanding primary medical literature, and interpreting statistical significance. Ideal for learners in health sciences aiming to enhance their research literacy.
Questions and Answers
- 1.
A good clinical question that will direct a search of the evidence for current, primary research studies consists of an intervention, target population, outcome, and comparison intervention.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true. A good clinical question should include the components of an intervention, target population, outcome, and comparison intervention. This helps to focus the search for current, primary research studies and ensures that the question is specific and answerable.Rate this question:

Databases of primary medical literature, such as PubMed/Medline, generally contain a compilation of only high quality evidence.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because databases like PubMed/Medline are specifically designed to include only high-quality evidence from primary medical literature. These databases go through a rigorous process of selecting and reviewing articles before including them, ensuring that the information available is reliable and trustworthy. Therefore, researchers and healthcare professionals can rely on these databases to access credible and evidence-based information for their work.Rate this question:

An electronic database such as PubMed can only be accessed from the university library.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False. An electronic database such as PubMed can be accessed from anywhere with an internet connection. It is not limited to access only from the university library.Rate this question:

Confidence intervals are a measure of clinical significance, and provide a way of estimating where the “true” result for any population lies.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Confidence intervals are indeed a measure of clinical significance because they provide a range of values within which the "true" result for a population is likely to lie. They take into account the variability in data and provide a level of certainty about the estimated result. Therefore, true is the correct answer.Rate this question:

The p-value is a measure of reliability.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The p-value is not a measure of reliability. It is a statistical measure that helps determine the significance of a hypothesis test. It represents the probability of obtaining the observed data or more extreme data, assuming that the null hypothesis is true. A lower p-value suggests stronger evidence against the null hypothesis, but it does not provide information about the reliability or accuracy of the results.Rate this question:

Which study design is best for a study about therapy?
Correct Answer
randomized controlled trial
RCT
rct
randomized, controlled, clinical trialExplanation
A study about a therapy (intervention) should include a large population (at least 30 subjects), with similar baseline characteristics, meeting tight inclusion and exclusion standards which is then randomly divided into a control (sometimes a "zero" group, often a placebo or comparison intervention) and an experimental or test intervention. The best RCTs contain blinding of subjects, those supplying the intervention, and those analyzing the results.Rate this question:

You have received a referral for a 38-year-old male client with chronic low back pain. He sustained his injury at work and is employed as a plumber. In addition to your standard chiropractic care, you are trying to decide if this man would benefit from using a Transcutaneous Electrical Nerve Stimulation (TENS) unit, and from attending a series of group education sessions on chronic pain management.Write a focused clinical question which will help you organize search of the biomedical literature as well as help determine relevance of the results to your patient.
- 8.
If you were to search PubMed for original research to answer your question, describe the search strategy you might use. Be as specific as you can about topics, keywords, and search categories (fields) you would use. Explain your rationale. Describe how you might limit your search. How would you determine which results were most relevant and best quality? How might you obtain access to full text?
