A choice of one's own research advance directives: Anticipatory planning for research subjects with fluctuating or prospective decisionmaking impairments

Mental disorders that may affect decisionmaking capacity, like schizophrenia, have a deleterious effect not only on persons who are afflicted with the disorders but also on their families, their friends, and their communities. Realizing research to develop generalizable knowledge that may benefit this heterogeneous population is crucial. The moral challenge is to fashion processes that both respect research subjects’ autonomy and protect their wellbeing. Research advance directives may provide a mechanism that authorizes potential research subjects to make choices of their own regarding whether they wish to participate in a research protocol, to choose and appoint a surrogate decision maker, and to secure an array of protections for themselves should they lose their decisionmaking capacity during the period of the research protocol. Such research advance directives may be used by persons with fluctuating, limited or prospective decisionmaking impairments.
