Hi all, I'd like to share with you a new theoretical piece I've written with Tony Ward, and our terrific PhD student, Sam Clack (pdf attached). It is a pretty dense piece, about what symptoms are in psychiatry, and not of general relevance to MECFS. But I'd love your input on the bit I've quoted below, and whether you think this might be a useful approach to use for delineating symptoms in ME from superficially similar ones in things like depression. We don't mention ME in the paper, and the example below is on fatigue, but I did wonder if there are some ideas here that could be followed up. I'm in a position to collect data too. Thoughts, anyone? Edit: The piece in now in press at Clinical Psychological Sciences. Reference: Wilshire, C. E., Ward, T., & Clack, S. (2020).
