Hello,

I was interested in undertaking a longitudinal analysis of the youth self-completion data. I've noticed a high level of attrition between waves 1 and 2. Of those who complete wave 1, only around 57% also complete the survey at wave 2. I tried to make sense of this attrition by looking at the technical manual but there were fewer details in regards to the youth self-completion data - do you know if this attrition largly down to refusal or are there other reasons for it?

I also wanted to ask about weights. Is there any plan to provide longitudinal weights for the youth self-completion data?

Thank you for your help.
