Question
1 . Create a longitudinal descriptive design to address: How do nursing students cope with stress during clinical practicum? Describe a research question, the setting/sample, and the data collection procedure.
2. Suppose we are interested in testing the effect of a special high-fiber diet on cardiovascular risk factors (e.g., cholesterol level) in adults with a family history of cardiovascular disease. Recommend a research design for this problem. Indicate what confounding variables you would need to control? How you would control them? Identify the major threats to the internal validity of the design.
Explanation / Answer
1. Longitudinal descriptive design
Research problem
Methods used by nursing students to adjust with stess during clinical practice.
Setting/Sample
Second year Bsc nursing students worked in medical ICU.
Data collection procedure
* Data collection from students with the help of following methods,
Observation
* Observing students in MICU for one month and assess their amount of
work and how they doing it properly and their management in emrgency
situvations and take feedbacks from students about their opinion in
practices in MICU.
Questionaires
* Preparing a questionaire about emotional problems of students in the
MICU.
Stress assessment tool
* creating a stress assessment tool to know the level of stress of students
worked in MICU.
2.Nonrandomized control group design is a type of experimental research design which is useful to
conduct this type of study.in this design experimental and control group selected without using
randomization. in this control group is people who not take high fiber diet with family history of heart
problems and experimental group is people who take high fiber diet with family history of heart
problems.
* In this problem confounding variable which is needed to control is the family history of cardiovascular
diseases. it can control through,
* Block the association between history of cardiovascular diseases and cholesterol
level both are result in future cardiac problems.
Major threats of internal validity of design in this research is,
* If mortality occur in any members both experimental and control group it affect
result of the study.
* if any of the group already practicing and continously following exercises which
affet the internal validity of study.
* Instrument used for checking cholesterol level should be accurate otherwise it
affect the entire study.
