This study analyzed patients’ perspectives about a measure of current, usual, and extreme pain and a measure of activity-related pain. Thirty-one patients with osteoarthritis participated in focus groups. Researchers completed thematic analysis of transcripts using coding software and an inductive approach. Three emerging themes were that many factors affected patients’ perceptions and ratings of pain intensity, patients used different approaches to construct pain ratings, and patients interpreted maximal response anchors differently. Particularly, novel findings were that patients evaluated pain fluctuation, location, duration, and quality when constructing pain intensity ratings. Also, activity items helped patients to remember pain and provided a valued context for communicating pain experiences. However, the activities needed to be sufficiently described and personally relevant. These findings further clarify the challenges patients face and the workarounds they use when rating pain intensity. The patients’ suggestions for improved administration methods and items warrant future investigation.
