Participants who complete the advance care planning interventions fill out an evaluation of the intervention using a 16-item questionnaire. This instrument comprises:
Twelve 5-point Likert-style questions on how the program presented various kinds of information; helped the user clarify values, choose a spokesperson, etc.; and helped the user document or be prepared communicate their wishes to others.
Three 10-point Likert-style questions on user overall satisfaction, with the advance directive created by the intervention, and the amount of information provided.
One open-ended item asking how the intervention was helpful.
