Which statement about self-report techniques is true?

• A. They can be cost-effective and allow large samples
• B. They always prove causation
• C. They require no participant input
• D. They require expensive laboratory equipment

Answer: (A)

Self-report techniques involve participants describing their own thoughts, feelings, and behaviours. This approach is cost-effective and scalable, which is why it can allow large samples. Questionnaires and interviews can be distributed to many people at a low cost, especially with online formats, providing data from diverse groups quickly. They are not about proving causation; they typically show associations and depend on participants’ honesty and memory, so they're subject to biases. They do require input from participants, and they do not depend on expensive lab equipment since many self-report methods use simple paper forms or online surveys.
