When High Schools Want to Ask Students About Sensitive Subjects

When high schools want to ask students about sensitive subjects like drug use or sexual health, they often use surveys rather than a more direct form of communication like interviews. Why?

A) Surveys allow respondents to speak in their own words; they can reveal their own thoughts, feelings, and beliefs.
B) Surveys allow researchers to ask much more complex questions than they could with any other methodology.
C) Surveys allow students to answer the questions in private and assure the confidentiality of their responses.
D) Surveys are more expensive and allow for larger staffs and budgets.
E) Surveys produce far more honesty and are almost always more valid.
