Case 1 (Questions 11-13) Suppose a team of researchers conducts a case-control study on the association between hypertension and stroke among adults aged 50 and older in Florida. For this study, the researchers selected Floridian adults aged 50 and older who experienced a stroke as the cases. As controls, the researchers selected Floridian adults aged 50 or older who did not experience a stroke. To assess each participant’s exposure status, the researchers asked the participants to fill out a questionnaire in which the participants were asked to retrospectively report if they have had hypertension in the past.   What source of measurement error could affect the measurement of hypertension in case 1? (2 points) Explain why you chose this source of measurement error (2 points).

Suppose a team of researchers conducted a retrospective cohort study on the effect of childhood adverse events on obsessive-compulsive disorder (OCD, which is a type of anxiety disorder) among adults aged 18-25. For their study, the researchers randomly selected a sample of 2,000 adults aged 18-25 living in the United States.   The researchers found a risk ratio of 2.32 indicating that individuals who experienced adverse childhood events had a 2.32 times higher risk of developing OCD compared to individuals who did not experience any adverse childhood events. The researchers wonder to what extent the finding from their study is valid for adults aged 18-25 living in Canada.   What is the type of validity are the researchers wondering about?
