Measuring more than one concept
Well, there’s more to writing a good questionnaire – but we won’t go into this now.
Lets say you’ve got a good questionnaire that works well.
You’ll likely try to include questions that try to explore what’s contributing to the depression, i.e. what are possible risk factors.
So, you’ll need items / questions that cover risk factors.
What do you think are some risk factors for depression?
Lets say you hypothesize that peer bullying is one risk factor, parent neglect is another, and low self-esteem is a third.
You would then develop a questionnaire that not only measures depression, but also measures bullying, parenting, and self-esteem.

In large studies, researchers could use more than one instrument of measurement. Below is an example of such a study.
