Pain has been defined by the International Association for the Study of Pain (IASP) as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage." The MOS focused on two basic dimensions of pain: severity in terms of intensity, frequency, and duration, and behavioral/mood effects. A 12-item battery of pain items was constructed.
