To examine a program for educating hypertensive patients at a community health center about the importance of recording weekly blood pressure results, a researcher conducts a study in which patient blood pressure (which is classified as (a) worse, (b) same, or (c) better) is better after an education intervention and usual care, as compared to only usual care. Identify the dependent variable(s) and independent variable(s) and match the variable to the type of measurement: Blood pressure: Education + usual care/Usual care.
Understand the Problem
The question is asking to identify and classify the dependent and independent variables in a study assessing the effect of an educational program on blood pressure management. The dependent variable is the outcome being measured (blood pressure), while the independent variable is the intervention applied (education plus usual care versus usual care alone). It also requires matching these variables to their types of measurement.
Answer
Independent variable: Type of care; Dependent variable: Blood pressure status
The independent variable is the type of care (education intervention + usual care vs. usual care only). The dependent variable is the patient's blood pressure status (worse, same, or better).
Answer for screen readers
The independent variable is the type of care (education intervention + usual care vs. usual care only). The dependent variable is the patient's blood pressure status (worse, same, or better).
More Information
In this study, the independent variable is the variable that is manipulated by the researcher, which is the type of care the patient receives. The dependent variable is the outcome being measured, which is the change in the patient's blood pressure status.
Tips
Common mistakes include confusing the independent and dependent variables. Remember, the dependent variable depends on the independent variable.
