Validity of single item responses to short message service texts to monitor depression: an mHealth sub-study of the UK ACUDep trial

摘要

BackgroundAn increasing number of research designs are using text messaging (SMS) as a means of self-reported symptom and outcome monitoring in a variety of long-term health conditions, including severity ratings of depressed mood. The validity of such a single item SMS score to measure latent depression is not currently known and is vital if SMS data are to inform clinical evaluation in the future.
