Swift Research & Evidence-Based Practice 2

Question 1

In evidence-based practice (EBP), which hierarchy level provides the STRONGEST evidence for clinical decision-making?

Accepted Answer

Systematic reviews and meta-analyses

Answer

Systematic reviews and meta-analyses synthesize results from multiple high-quality studies, placing them at the top of the evidence hierarchy.

Question 2

A social worker wants to evaluate whether a new intervention reduced client anxiety. Which design is most appropriate when random assignment is not feasible?

Accepted Answer

Quasi-experimental design

Answer

Quasi-experimental designs allow for comparison groups without random assignment, making them practical when randomization is ethically or logistically impossible.

Question 3

What does 'statistical significance' (p < 0.05) indicate in research findings?

Accepted Answer

There is less than a 5% probability the result occurred by chance

Answer

A p-value below 0.05 means there is less than a 5% probability the observed result is due to random chance alone.

Question 4

Which sampling method gives every member of the target population an equal chance of being selected?

Accepted Answer

Simple random sampling

Answer

Simple random sampling ensures each individual in the population has an equal and independent probability of selection, maximizing representativeness.

Question 5

In qualitative research, 'member checking' is used primarily to enhance which quality criterion?

Accepted Answer

Credibility

Answer

Member checking involves returning findings to participants for verification, which strengthens the credibility (internal validity equivalent) of qualitative data.
