In research methodology, when individuals are asked to report values or variables themselves, this is known as self-reporting. Self-report measures often include surveys, questionnaires, or interviews where the subjects provide information about their own experiences, behaviors, or perceptions. This method is commonly used in psychology, social sciences, and health research to gather subjective data directly from participants.

Self-reporting has its advantages, such as providing firsthand insights and being easy to administer. However, it also comes with limitations, including the risk of bias (such as social desirability bias), inaccuracies in memory, or misunderstanding the questions. Therefore, researchers are encouraged to complement self-report data with objective measures or third-party observations when possible to enhance the robustness of their findings.
