Note: ISCIBPDS = International Spinal Cord Injury Basic Pain Data Set; see Appendix for specific wording of each item. Three pain interference scales can be computed from the six interference items: Total Interference (average of all six items), LSF Interference (average of the Limit activities, Social/recreational changes, and Family-related changes interference items), and AMS Interference (average of the Activity, Mood, and Sleep interference items).
