Design a survey
In the text book (see Box 13.1) and in class we reviewed four steps to survey design first outlined by Campbell & Stanley (1953). Think of a survey topic - people's attitudes toward some topic, knowledge about some issue, or some important behavior(s) - and using Campbell's four steps, briefly describe how you would design a survey.
1. What general theme or question are you interested in.
- What is the "phenomenon" you will investigate?
- Why is it important? What theory underlies your question or approach?
- Hint: keep your overall question specific and straightforward. You will need to operationally define it using a (relatively) small number of survey items.
2. Operationally define your phenomenon: Are you assessing knowledge, attitudes or beliefs, or actual behaviors (or some combination?
- Why are you assessing the term(s) you chose?
- How would the study differ if you operationalized your phenomenon differently, e.g., by assessing self-reported behaviors rather than attitudes, or knowledge instead of behavior?
- Can participants validly report the knowledge, attitudes or behaviors you are interested in?
3. What sampling approach will you use? (Sampling notes here or in the text).
- Will you use a probability or a non-probability sample?
- What form of sample will you use within each of these categories, and what are the implications for your results of choosing one or another?
4. Write some questions.
- Your items can be open- or closed-ended, Likert-type rating scales, checkboxes, or simple multiple-choice questions.
- Why did you choose the type of question you did, and how will that choice affect your results?
