What makes a study using a cross-sectional questionnaire a retrospective questionnaire study? They are QOL studies for children with hearing problems who are being assessed by the Glascow Children's Benefit Inventory (GCBI).

Here are at least two that use the term:

Here are three questions from the questionnaire:

1. Has your child's operation made his/her overall life better or worse?

2. Has your child's operation affected the things he/she does?

3. Has your child's operation made his/her behavior better or worse?

Is it because of the past tense verb - 'has your child's ...." instead of "is your child's ... overall life better since the operation?"
