Self-reporting technique is a method of gathering data where participants provide information about themselves without interference from the experimenter. Self-report techniques can include questionnaires, interviews, or even diaries, and ultimately will require giving responses to pre-set questions. Self-report methods allow researchers to see into the minds of their participants, giving them more information than observation alone and can contextualize data collected from experiments, making the data gathered more valid. Self-report techniques involve getting information directly from the source without experimenter interference. Diary entries, questionnaires, and interviews are examples of self-report methods. Self-report studies have many advantages, but they also suffer from specific disadvantages due to the way that subjects generally behave. Self-reported answers may be exaggerated, respondents may be too embarrassed to reveal private details, and various other threats to the validity of self-report are due to respondent characteristics.
