How the psychosocial context of clinical trials differs from usual care: A qualitative study of acupuncture patients

Background Qualitative studies of participants' experiences in randomised clinical trials (RCTs) suggest that the psychosocial context of treatment in RCTs may be quite different to the psychosocial context of treatment in usual practice. This is important, as the psychosocial context of treatment is known to influence patient outcomes in chronic illness. Few studies have directly compared the psychosocial context of treatment across RCTs and usual practice. In this study, we explored differences in psychosocial context between RCT and usual practice settings, using acupuncture as our model.
