Thanks. (I don’t have access to the full text). So not the exact same population, but still a comparison of “adolescents in grade 5-9 at time 1 and grade 8-12

Thanks. (I don’t have access to the full text). So not the exact same population, but still a comparison of “adolescents in grade 5-9 at time 1 and grade 8-12 at time 2”? That would compare a pre-puberty to a puberty population, with the unsurprising result of them being less compliant. But again, I don’t have access to the full text.

The authors specifically said that the elementary schools sampled at Time 1 fed into the high school at Time 2, but they didn't say that the data was paired ie: the set of students sampled at Time 1 = the set of students sampled at Time 2. The response rate is so high that there is likely considerable overlap tho.
