A comparison of primary dysmenorrhoea and intrauterine device related pain

Abstract
A pain questionnaire designed to measure sensory, affective, evaluative and temporal components of pain was administered to 119 patients with primary dysmenorrhea and 75 patients with intrauterine devive (IUD) related pain. In addition, self-report information was obtained on the behavioral effects of pain, global ratings and biographical details of these patients. Dysmenorrhea and IUD related pain were generally similar in nature. This led to the conclusion that IUD insertion does not in general lead to an exacerbation of presenting dysmenorrhea, nor does it radically alter the type of sensations experienced by the patient. While no differences between patient groups emerged, the implications of the different pain components did vary. Pain intensity scores were reflected in a larger sensory component with IUD users, but with dysmenorrhea the affective component predominated. The results show sufficient consensus in the 2 patient groups of word adjectives used to describe their pain, to allow the development and evaluation of a rapid card sort system for pain assessment.
