Self-report methods

In one line: Sometimes the best way to find out what people think or feel is simply to ask them.

A self-report method is ideal for studying inner experiences that can't be observed. The two main types are questionnaires and interviews.

This links to the concept of measurement: self-report turns private experience (like anxiety) into data, for example a rating on a scale, so a hidden feeling becomes something that can be compared.

Memory hook: Ask, then record. Self-report measures what people say about themselves.

Key idea: Questionnaires reach many people quickly; interviews go deeper. Interviews vary from fixed to free.

Take studying exam anxiety. A questionnaire with a 1–10 anxiety scale reaches a whole year group quickly (quantitative). A semi-structured interview with a few students explores why they feel anxious (qualitative depth). Both are measurements of the same experience.

Go further — higher-level insight: The big self-report problem is honesty. People may give socially desirable answers — saying what looks good rather than the truth. Anonymous questionnaires reduce this; a skilled interviewer builds trust. Naming this bias, and how to reduce it, is a high-level evaluation move.

Key idea: Self-report is the best way to access inner experience, but it depends on honesty and accuracy.

So self-report is the main way to study inner experience, but a good evaluation notes it depends on honesty (social desirability bias), on accurate self-knowledge, and on unbiased questions — leading questions and interviewer effects can distort the data.

Watch out: A leading question invents the answer. 'How annoying was the noise?' assumes it was annoying. Neutral wording is essential, or the measurement is biased.
