Any comments on specific survey questions that may have caused difficulty? No problems. My children were fully briefed before the survey and they understood that they could miss questions if they did not want to answer them. We did not have any children with any concerns regarding the survey at all.
Any comments on the use of the web site? No it was easy to use.
Any general comments on the exercise? The children really enjoyed completing the survey, It has lead to many positive discussions about our health and how we all have slightly different experiences and home lives.
