At home, the subject will assess pain intensity at rest each day at noon (± 4 hours). This assessment should capture her average pain at rest in the prior 24 hours by assessing "What has been your average pain since your last pain assessment?" (ie, from noon on the previous day to the current assessment). At the same time, the subject should record any pain medication (medication name, date, time, and dose) taken in the prior 24 hours.
