    ContextAlthough measures that assess patient engagement in the advance care planning (ACP) process exist, there are no validated tools to assess surrogate decision makers' (SDMs') role in ACP.ObjectivesThe objective of this study was to adapt and begin to validate a patient-oriented questionnaire for use with SDMs of patients with chronic illness.MethodsQuestions from the 55-item patient-oriented ACP engagement survey were adapted for SDMs and assessed for face validity. The resultant 47-item questionnaire was administered to 65 SDMs of patients with chronic illness. Responses were assessed and items were flagged for removal based on item redundancy, nonresponses, and ceiling effects. A preliminary exploratory factor analysis was performed, internal consistency was assessed, and domains were constructed based on findings.ResultsThe 47-item questionnaire was administered to 65 participants (mean age 51.8; 81% female; 96% Caucasian). Seventeen items were removed owing to redundancy (r > 0.80), and 13 items lacking face validity were removed. In a preliminary exploratory factor analysis of the resultant 17-item questionnaire, a three-factor solution was deemed most statistically and conceptually sound. Items were organized into domains: 1) serving as an SDM (seven items); 2) contemplation (four items); 3) readiness (six items). Internal consistency for each domain was high (Cronbach alpha 0.90-0.91).ConclusionThe 17-item ACP engagement survey for SDMs (ACP-17-SDM) is a conceptually sound and reliable questionnaire adaptation of the original ACP engagement survey. This questionnaire may be used by researchers in parallel with the patient-oriented ACP engagement survey to more fully understand the impact of ACP interventions on SDMs. Larger studies are needed to more closely examine construct validity.Crown Copyright © 2019.
