protocol of the MOOVD study

Paper instructions:
I need your help in writing my research proposal.
Attached you can find the protocol of the MOOVD study and an article that explains time series analysis. What I need is to write a nice research on these data. The following question is going to be my research question:
If depressed and non-depressed individuals differ on their level of physical activity, are these differences similar or not when comparing objective measurements of physical activity (hand watch) and subjective measurements (questionnaire)?

Please note that this order concerns only writing the research proposal (an order of writing the whole research will follow).

A blank research proposal form is attached (see: Research Proposal Form). You are kindly requested to follow this form in order to write my proposal. An example on how to follow this form to write a research proposal is also attached (see: Proposal Example).
