A qualitative study of changes in expectations over time among patients with chronic low back pain seeking four CAM therapies

摘要

BackgroundThe relationship between patient expectations about a treatment and the treatment outcomes, particularly for Complementary and Alternative Medicine (CAM) therapies, is not well understood. Using qualitative data from a larger study to develop a valid expectancy questionnaire for use with participants starting new CAM therapies, we examined how participants’ expectations of treatment changed over the course of a therapy.
