DESIGN: Eighty-four patients with solid tumor, NF1 or leukemia ages 8 to 34 and up to 108 parents of these patients ages 8 to 25, and 69 patients with SCD will be asked to respond one time to the PII and the PRS, as well as the Modified Brief Pain Inventory and Faces Pain Scale - Revised during a scheduled clinic visit for their primary NCI protocol, or while inpatient.
In addition, demographic (patient gender and age, parent gender (if applicable) and medical (diagnosis, date of diagnosis, pain medication) data will be collected from review of the patients medical record.
Put differently, vignette based corrections appear quite effective in bringing objective and subjective measures closer together.
