What defines "self-report measures" in research?

Self-report measures in research are defined by the requirement for participants to evaluate and provide insights regarding their own behaviors, attitudes, feelings, or experiences. This approach allows researchers to gather direct information from individuals, often through surveys or questionnaires. Participants reflect on their personal perspectives, which can be critical for understanding subjective experiences and perceptions in psychological studies.

Such measures are particularly valuable because they can capture complex thoughts and feelings that may not be observable externally. Researchers rely on self-reports to delve into personal and introspective data that are vital for assessing constructs like mood, personality traits, or behavioral intentions.

Employing self-report measures provides a unique perspective that is essential in psychology, even if it comes with potential biases, such as response biases or issues of self-perception. The other options refer to methodologies that do not involve participants’ self-assessment, such as observational methods, evaluations by external observers, or purely statistical data analyses, which all focus on external data rather than the individual's own account.
