What are the common types of questions used in epidemiological studies?
In epidemiological studies, questions can be broadly categorized into several types: - Closed-ended questions: These questions provide predefined options, making it easy to analyze responses statistically. Example: "Have you been vaccinated for influenza this year? (Yes/No)" - Open-ended questions: These questions allow respondents to answer in their own words, providing richer data. Example: "Can you describe the symptoms you experienced during the illness?" - Likert scale questions: These questions measure attitudes or perceptions on a scale, such as strongly agree to strongly disagree. Example: "On a scale of 1-5, how would you rate your overall health?"
