Question 1

A case-control study recruits individuals WITH a condition (cases) and WITHOUT a condition (controls). This design is BEST for studying:

Accepted Answer

Rare diseases or conditions with long latency periods

Answer

Case-control studies are efficient for rare conditions because they start with known cases and compare retrospective exposure histories with matched controls.

Question 2

Publication bias in research refers to:

Accepted Answer

The tendency for positive results to be published more often than null results

Answer

Publication bias skews the available evidence base toward positive findings, as studies with statistically significant results are more likely to be published.

Question 3

An athletic trainer uses a clinical prediction rule (CPR) that has been validated in a population different from their patient. The MOST appropriate action is to:

Accepted Answer

Apply the CPR cautiously while considering differences between populations

Answer

CPRs developed in different populations may have reduced accuracy; clinicians should note population differences and apply CPRs with appropriate caution.

Question 4

Which statistical measure is used to quantify the agreement between two categorical raters beyond chance?

Accepted Answer

Cohen's kappa

Answer

Cohen's kappa measures inter-rater agreement for categorical variables, accounting for the level of agreement expected by chance alone.

Question 5

In the context of EBP, patient values and preferences refer to:

Accepted Answer

The patient's unique concerns, expectations, and goals regarding their care

Answer

Patient values and preferences encompass individual patient goals, concerns, cultural beliefs, and expectations that must be integrated into clinical decision-making.
