Assessing the assessment measures for menstrual cycle symptoms: a guide for researchers and clinicians.

A review of measures of menstrual cycle symptoms is provided. This will enable researchers and clinicians to make the appropriate choice of method for their study requirements. In recent years, these measures have taken the form of retrospective questionnaires (rating severity of symptoms from memory) and prospective diaries (daily checklists of symptoms). Many of these draw on aspects of the well-known retrospective questionnaires, the Menstrual Distress Questionnaire and Premenstrual Assessment Form, in their development and validation. Each measure will be briefly described, followed by comments on its development, psychometric properties and finally an evaluation of its strengths and weaknesses. It concludes with an examination of the implications arising from the review, and some recommendations that menstrual cycle researchers and clinicians may wish to consider, as they decide upon the most appropriate measure for their needs.
