To make an impact on the state of ACP for patients with AD and their surrogates, the researchers will adapt and pilot test an efficacious ACP intervention, SPIRIT (Sharing Patient's Illness Representations to Increase Trust), with patients with mild AD and their surrogates to promote open, honest discussions while such discussions about end-of-life care are possible. SPIRIT is a brief, scalable patient- and family-centered ACP intervention based on the Representational Approach to Patient Education with a goal to promote cognitive and emotional preparation for end-of-life decision making for patients with a serious or life-threatening illness and their surrogates. SPIRIT focuses on having both the patient and the surrogate fully understand end-of-life decision making in anticipation of a loss of decision-making capacity.
