A nurse researcher develops a new scale to measure preparedness for caregiving
among family members of palliative care clients. A panel of experts is convened to
assess whether the items on the draft scale adequately reflect the construct. What
type of validity is being assessed?

Content validity
-Content validity is the extent to which a multi-item scale's content (the
items) adequately captures the focal construct. Content validity, unlike
, criterion or construct validity, is typically assessed with feedback from a
panel of experts. Face validity refers to whether the scale looks like it is
measuring the target construct.
When a nurse researcher selects an instrument for a study, what is the primary
consideration?

Its conceptual relevance
-The selection of existing instruments should be based on many
considerations, but the primary one is its relevance to the concepts of
interest. Other considerations include the quality of data that the instrument
yields, the researcher's familiarity with it, and its cost, population
appropriateness, and reputation.
A nurse researcher is studying fear of falling in community-dwelling elders. Which
might be a reasonable exclusion criterion?

People younger than age 65
-The study is focused on community-dwelling elders, and so it would be
reasonable to exclude people below a certain age limit (here, age 65
years). The researcher is thus defining "elder" as someone who is 65 or
older. One inclusion (rather than exclusion) criterion might be living
independently in one's own home. There would be no apparent reason to
exclude married people or people who experience dizziness (which could
contribute to fear of falling).
