First and foremost, the authors would like to thank all the families who have given up their time to take part in the study and have supported it continuously sweep by sweep.
The Growing Up in Scotland study is very much a collaborative venture. We owe a huge debt of gratitude to our colleagues in NatCen's operations and computing departments and to our team of interviewers and supervisors for conducting the interviews with such dedication and professionalism.
We are grateful for the input of Growing Up in Scotland leads at the Scottish Government - Ganka Mueller, Robyn Bailey and Sarah Newton - and for the advice received from their colleagues who formed the project's advisory group.
Responsibility for the opinions expressed in this report, and for all interpretation of the data, lies solely with the authors.
