Which type of measure involves participants reporting their own feelings or behaviors?

Self-report measures involve participants directly providing information about their own feelings, thoughts, or behaviors. This type of measure is fundamental in research, as it allows researchers to gather subjective data directly from individuals, giving insight into their personal experiences and perceptions. Self-report measures can take various forms, such as surveys, questionnaires, or interviews, and they are often used to assess emotions, attitudes, beliefs, and behaviors.

In contrast, observational measures rely on researchers observing and recording behaviors without directly asking participants about their feelings or thoughts. Experimental measures focus on manipulating variables to determine cause-and-effect relationships, while biased measures refer to data collection methods that may lead to skewed or unrepresentative results due to various factors, such as leading questions or lack of anonymity. Therefore, the clarity and subjectivity that self-report measures provide make them an essential tool in psychological research.
