In the medical and social research concerning "sexual activity" of man or woman, for example:

Can tampon use cause hymen changes in girls who have not had sexual intercourse?

Nevertheless, clefts were found in both the sexually active and the never-active groups: 20 of their 200 never-sexually-active subjects possessed complete hymenal clefts, as did only 84 of their 100 sexually active subjects

Is the status "sexually-active" usually self-reported by the patients? How trustworthy is this data? What if someone misreport their status? What are some mechanisms to prevent lies?

  • Did you provide the wrong link? You linked to an article about tampon use by young girls. What does that have to do with your question?

    What other method do you think would be more accurate than self-report?
