- Read the following article:
Williams, P.D., Piamjariyakul, U., Graff, J.C., & Stanton, A. (2010). Developmental disabilities: Effects on well siblings. Issues in Comprehensive Pediatric nursing, 33, 39-55.
- Discuss the findings from the article and the themes discussed by the researchers. As a professional who will provide family-centered services, how can you include siblings in the supportive therapeutic process? Also, consider what responsibilities the siblings may encounter as they move into adulthood.

NAME: ________________________________________________________________
Q1. A researcher wanted to assess the incidence of a disease in a population. What is the most appropriate study design would you recommend?
A. Case-Control study
B. Case report
C. Ecological
D. None of the above
Q2. The method of analysis in a given study would typically depend on
A. Research question
B. Study design
C. Type of subject
D. All of the above
E. A and B
Q3. Which of the following designs is best for testing a causal relationship?
1. Cross-sectional
1. Ecological
1. Case-control
1. Experimental trials
1. Case report/case series
Q4. Stratification does not allow for a straightforward and simultaneous examination of the possible presence of both confounding and effect modification.
A. True
B. False
C. None of the above
Q5. A potential weakness of cross-sectional research is that it cannot estimate incidence
A. True
B. False
C. None of the above
Q6. You are interested in testing if there is an association between marital status (married, divorced, separated) and BMI (quantitative).
Which of the following is the most appropriate statistical test that you will you use?
A. One-sample T-test
B. Independent Sample t-test
C. Chi Square test
D. None of the above
Q7. Two thousand (2,000) adults ages 50 to 80 years were recruited into a 10-year prospective cohort study which started in 1971. The purpose of the study was to examine the effect of gender on death at the end of the study (died during the study period vs survived), controlling for age, years if smoking, and occupation. What is the most appropriate statistical analysis you would conduct to answer the research question?
A. Multiple linear regression
B. Survival analysis
C. Multiple logistic regression.
D. All of the above
Q8. Which of these is not a criterion for explaining causality according to Austin Bradford Hill?
A. There is a dose-response relationship
B. Temporality of the exposure and disease are appropriate
C. The observed relationship between exposure and the disease is due to design error.
D. None of the above
Q9. What type of research goal would be most appropriate for studying emerging or rare diseases, and why?
A. Descriptive research goal
B. Causal research goal
C. Association research goal
Q10. Which of the following will help to mitigate confounding?
A. Multiple regression model
B. Randomization
C. Stratification
D. All of the above
Q11. Which of these statistical tests is the best for comparing a pre-test and a post-test?
A. Independent sample T-test
B. Paired sample T-test
C. ANOVA
D. None of the above
Q12. Which of these responses is false about adjustment by stratification?
A. It is carried out only for the association between one independent variable and two outcomes at a time
B. It allows for adjustment only for categorical variables
C. Data becomes sparse when the strata are too numerous
D. All of the above
Q13. You conducted a study to assess the effect of smoking on systolic blood pressure. The results showed that there was a significant association between the two variables, with an odds ratio of 1.5. Explain this finding to someone who has no background in epidemiologic research.
PSPP
Q14. Using the Practicum data, run the frequency distribution for age (“Age”) and marital status (“Marital”) and interpret your results. You are not required to include your output.
Q15. Using the Practicum Data, examine the relationship between the variable alcohol type (“alcoholtype”) and systolic blood pressure (“sbp”) and interpret your results. You are not required to include your output.
