Dear Andrew, The Delphi is one qualitative method - in qualitative research you want to see triangulation of methods- meaning that you use more than one method to look at the same thing and you should come up with a consistent answer. For critical appraisal of qualitative methods see the respective users guides published in JAMA (http://www.cche.net/usersguides/qualitative.asp). You will see that the rules can be easily applied to that particular methodology. It would be interesting to relay to the list how this one goes. Good luck Hope this helps a little, V -----Original Message----- From: A.Booth [mailto:[log in to unmask]] Sent: Monday, May 27, 2002 10:32 AM To: [log in to unmask] Subject: Critically appraising a Delphi Study I facilitate a monthly critical appraisal group across Sheffield called Shebang. We look at papers suggested by the group for either methoidological or topical reasons. (For a feel of the last year's papers look at our website: http://www.shef.ac.uk/~scharr/ir/sheafs/) The group has decided to do a Delphi study for a future session and has selected: Peters J et al. (2001) What role do nurses play in Type 2 diabetes care in the community: a Delphi study. J Adv Nurs 34 (2): 179-188 My questions to the list are three-fold: 1. Is anyone aware of a checklist for appraisal that specifically addresses Delphi studies? 2. If not has anyone appraised a Delphi study before and if so which generic checklist did you use? 3. What questions do you as experts in eb healthcare think that we should ask of a delphi study? Please be assured that if you reply to this email I will not be sending you out a further list of critical appraisal criteria to prioritise :-) and so on and so on!
