Swift Research & Evidence-Based Practice 5

Question 1

A social worker administers the Beck Depression Inventory (BDI) and PHQ-9 to the same client and obtains similar scores. This demonstrates:

Accepted Answer

Convergent validity

Answer

Convergent validity is supported when two instruments measuring the same construct yield highly correlated results.

Question 2

Survivor bias in research occurs when:

Accepted Answer

Only participants who completed the program are included in outcome analyses

Answer

Survivor bias occurs when analyses include only those who remained in a program, ignoring dropouts who may have had worse outcomes, leading to inflated estimates of success.

Question 3

Which level of measurement allows for meaningful ratios (e.g., 'twice as much') and has a true zero point?

Accepted Answer

Ratio

Answer

Ratio-level measurement has a true zero point, meaning the absence of the variable, which allows meaningful ratio comparisons between values.

Question 4

In evaluating research for EBP, the PICO framework stands for Population, Intervention, Comparison, and:

Accepted Answer

Outcome

Answer

PICO structures clinical questions by specifying the Population, Intervention, Comparison condition, and Outcome of interest to focus literature searches.

Question 5

A researcher recruits participants by asking initial participants to refer others from their social networks. This is called:

Accepted Answer

Snowball sampling

Answer

Snowball sampling leverages social networks to recruit hard-to-reach populations, with each participant referring additional participants.
