Study Summary: The objective of the study was to interview current vegetarians and
former vegetarians to explore their perceptions of the vegetarian diet and whether their
perceptions had changed over time. The instruments used were semistructured
interviews and focus groups. The study was a cross-sectional study, meaning that the
study took place at the same point in time in the given population (Barr & Chapman,
2002).
A. Is the study quantitative or qualitative?
B. Is the study basic or applied?
C. Is the primary purpose of the study to explore, describe, analyze, or predict?
D. Is the study experimental?
E. Is the study a randomized controlled trial? Could it be an intervention or outcomes
study? Is the study epidemiological or translational in nature? - ANSWER A. qualitative
B. applied
C. explore
D. No
E not randomized into groups its an outcomes study
. Study Summary: The objective of the study was to test whether adding a dietitian to a
hospital discharge team for geriatric patients would improve the nutritional status of
those patients over 6 months. Geriatric patients were randomly assigned to either the
regular discharge team or the discharge team with the dietitian. All patients were at
least 70 years old and determined to be at nutritional risk. The dietitian gave each
discharged patient three home visits within 8 weeks of discharge. Nutritional status was
measured using weight, muscle strength, and other measures. Adding a dietitian to the
discharge team did improve the nutritional status of geriatric patients (Beck et al.,
2015).
