Self-report research involves collecting data directly from individuals through interviews, questionnaires, surveys, diaries, or other self-administered methods. This data can include information about a person's thoughts, feelings, behaviors, beliefs, attitudes, experiences, or preferences. Self-report research is commonly used in psychology, sociology, health sciences, market research, and other fields to gather subjective information from study participants. This method allows researchers to access the internal experiences and perspectives of individuals, providing insight into their thoughts and behaviors. However, self-report data may be susceptible to biases, inaccuracies, or social desirability effects, so researchers must consider these limitations when interpreting the results.
