The one-dimensional intensity scales can be modified to produce a pain relief scale, a patient pain satisfaction scale, or a pain management index (4). Moreover, comprehensive multidimensional pain assessment tools such as the Brief Pain Inventory were developed to help pain management specialist's measure and assess the effect of pain on mood, activities, and quality of life—which one-dimensional tools cannot do. (2) These tools are more difficult for the patients and the medical personnel to complete and are usually not used in daily practice (1).
