Round 2 Introduction

Welcome to Round 2 of the COS-DIP Delphi survey!

This questionnaire is similar to Round 1 with the following differences:

> 12 items remaining after removing items not rated critically important in Round 1

> 1 item added based on feedback from Round 1

> For each item, you will be shown the feedback from Round 1, including your own previous rating and the rating of your stakeholder group (either people with Parkinson's disease, family members/family caregivers or healthcare professionals/researchers). 

Please re-rate the importance of each item in the questionnaire. You can choose to keep the same rating as in the previous Round 1 or change your rating based on the feedback displayed.

Again, you can rate each item on a scale of 1-9, with 1-3 being of limited importance, 4-6 being important and 7-9 being critically important. Please note that the COS-DIP represents a minimum set of outcomes. Depending on individual research questions and objectives, future studies will need to measure other outcomes in addition to the core outcomes. It should take about 10 minutes to complete. 

Please complete this questionnaire by 5 March 2024 the latest.
