The aim of this study was to measure expert consensus on the implementation of Psychiatric Advance Directives (PADs) within the Veterans Health Administration. We conducted a two-round Delphi study with 55 panelists including consumers, caregivers, mental health providers and researchers. For a number of items where no positive or negative consensus was reached we found differences between the views of consumers and non-consumers, reflecting consumer's preferences for nonmedical settings for completion and assistance with completion independent of the treatment team. Thus, the principle of consumer choice that applies to MHAD content should also be applied to the process of completion offered.
