CED Research Methods & Evidence-Based Practice 3

Question 1

In a dispatch quality improvement study, 'process measures' refer to:

Accepted Answer

Actions taken during the dispatch process itself

Answer

Process measures evaluate the specific actions and steps performed during care delivery, such as protocol adherence and time-to-dispatch.

Question 2

A researcher reports a p-value of 0.03 for a dispatch study finding. This means:

Accepted Answer

There is a 3% probability the result occurred by chance if the null hypothesis is true

Answer

A p-value of 0.03 means there is a 3% probability of observing the data (or more extreme data) if the null hypothesis were true.

Question 3

What is the primary purpose of a literature review before conducting dispatch research?

Accepted Answer

To identify existing evidence, gaps, and avoid duplicating prior work

Answer

A literature review summarizes existing knowledge, reveals research gaps, and ensures the new study builds meaningfully on prior evidence.

Question 4

Which data collection method would best capture the lived experience of dispatchers handling mass-casualty events?

Accepted Answer

In-depth qualitative interviews

Answer

Qualitative interviews allow dispatchers to describe their experiences in depth, capturing nuances that structured quantitative tools cannot measure.

Question 5

What is 'external validity' in dispatch research?

Accepted Answer

The degree to which findings can be generalized beyond the study sample

Answer

External validity refers to how well study findings can be generalized to other populations, settings, or time periods.
