What is your current understanding of Reliability and Validity?

Give a similar example of a research tool that would also be consistent.

Why is "do you go to the toilet often" a bad question?

Why is "do you have difficulty getting dressed?" a bad question?

Why is "Do you exercise regularly?" as bad question?

Change the question to make it increase validity - "do you go to the toilet often?"

Change the question to make it increase validity - Do you have difficulty getting dressed?

Change the question to make it increase validity - Do you exercise regularly?
