The goal of the current study is to evaluate a decision-support tool intended to help primary care providers (PCPs) communicate with patients about blood biomarker testing for Alzheimer's Disease, enhancing shared-decision making and information sharing in the clinical space. The main questions it aims to answer are:
* Is the decision-support tool accepted and easy to use for PCPs? * Does using the tool improve shared decision-making during clinical encounters? Researchers will compare clinical encounters between PCPs who do not use the tool to discuss blood biomarker testing for Alzheimer's Disease, versus PCPs who have been trained to utilize the tool during clinical encounters to see whether the tool effectively facilitates shared-decision making.
Simulation 1 and Simulation 2: PCPs with experience and interest in cognitive diagnosis.
Simulation 2: community dwelling older adults age 50 or older are eligible.

Shared decision-making support tool
Other interventionBased on previous data analysis, the decision-support tool is intended to facilitate discussions between the patients and their providers regarding the Phospho-Tau blood test. It functions as a flowchart to provide clear, accessible information about the blood test that will assist providers in discussions around guide the patients through navigating a diagnostic workups for memory problems.
Effectiveness of the tool on shared decision-making as measured by OPTION-5 Score
Effectiveness of the tool on shared decision-making will be measured by OPTION-5 score, a validated measurement to quantitatively evaluated shared decision-making process from the observers' perspective. The total range of scores is from 0-100 where higher scores indicate greater patient involvement
Effectiveness of the tool on shared decision-making assessed by SDM-Q-9.
SDM-Q-9 is a 9-item questionnaire that evaluates the shared decision-making (SDM) process from the patient's perspective. Individual items range from "completely disagree" (0) to "completely agree" (5), yielding a raw sum score between 0 and 45, where higher scores demonstrate increased effectiveness.
Acceptability and usability of the tool as measured by an adapted System Usability Scale (SUS)
The System Usability Scale (SUS) is a short 10-item questionnaire that presents a subjective assessments of usability. The scores are calculated by adjusting odd- and even-numbered item responses, summing the adjusted scores (0-40), and multiplying the total by 2.5 to produce a final score ranging from 0 to 100, where higher scores indicate increased acceptability and usability.
Acceptability and usability of the tool as measured by Practitioner Opinion Survey
The Practitioner opinion survey (POS) is a questionnaire that contains 15 items that assess the usability and acceptability of the shared decision-making tool. The total score range is from 15-75, with higher summed score indicating higher usability and acceptability from the perspective of the providers.
