I am new to programme evaluation, and I am planning to evaluate my programme. I want to know what to look for when I design questionnaires.

You are welcome! Good luck!

Thanks for your tips! That’s very helpful!

I think you might want to avoid making the questionnaires too long, as it might tire participants. You might also want to choose scales that have reversed items to avoid the response bias, which means participants tend to choose similar score for each item on the same scale. Here are the two things I generally look for. Hope they can help!
