Ms Eimear Murphy:

I shall answer one of the questions asked. We could not divide male adolescents from female adolescents because their numbers were too small. If we return to this work, we would like to examine that point. We did not ask whether people knew what the effects of alcohol were. As such, we do not know whether they knew.

We were also asked why we did not examine hazardous drinking by adolescents and parents. We used the system of univariate logistic regression which gives stronger evidence.
