Our goal is to compare two types of advance directives forms available in English and Spanish to determine which is more easy to use for patients.


Step1: Any adult participant who is interested in completing advance directives and able to read and write in English and or Spanish will be eligible to participate in the study

Step 2:

Online Stanford consent form will be presented before the participants. Only after they read the consent and click on the participation link will they be able to enter the study.Those who are willing to participate will be randomly assigned to either the letter or traditional advance directives in Spanish and study measures. They will also answer questions as to how much they liked and understood the documents.

Step 4: The investigators will collect data until the investigators reach an n=1000

Step 5: The investigators will analyze the results and submit for publication.

In this protocol, we are assessing whether patients prefer the traditional advance directives or the letter directive. As it is just an questionnaire based study, there no risk for patients.
