My PhD thesis examined the effect of peer influence on the development of adolescent alcohol use. Peer influence is one of the most salient and consistent predictors for drinking behaviour among young people. It is important to understand the relative contribution of the processes of peer influence (whereby adolescents transition to alcohol use in the presence of alcohol-using peers) and peer selection (whereby those using alcohol initially in the absence of alcohol-using friends then subsequently seek out drinking peers) so that appropriate prevention strategies can be applied at different stages in adolescence. Using cross-national, prospective data from state-representative samples of students in Grades 5, 7 and 9 in Victoria, Australia and Washington State, USA from the International Youth DevelopmentStudy, I used Latent Transition Analysis to identify a range of transition groups with adolescents moving in and out of their latent peer classes over time and explored predictors associated with these transitions. The findings provide the firmest estimates to date of the prevalence of peer influenced alcohol use transitions and demonstrate age and country variations.

Merel and Nadia, two child psychology students from the Netherlands spent eight weeks doing a student placement within two of our research projects. They were at the Centre for Adolescent Health to write their bachelor’s thesis.
They told us “It was a great experience being here. It was a pleasure to see how the Murdoch Childrens Research Institute and Royal Children’s Hospital research teams operate. All the co-workers are interested in each other’s project. It was a wonderful experience being here and to meet all the nice staff! We learned a lot about what research is and it was great to see how the staff worked together and were very helpful to each other. We loved our internship at the Centre for Adolescent Health and to see the brand new hospital with all the child friendly facilities. It is amazing that everything is just there in one hospital. We had a great time!”

The CATS study is a new and unique longitudinal study of children in metropolitan Melbourne as they approach adolescence. The study began in 2012 and is following over 1200 children from grade 3 (8-9 years of age). It will cover the experiences of children and their families, their changing social context as they move into secondary school, and the biological changes of puberty. Findings from this study will be used to determine which children are most at risk as they pass through puberty and the middle years of school, and to see if certain modifiable factors may be a target for preventative interventions.

This paper reports on research from the Longitudinal Study of Australian children, in which parents of children were interviewed over time, and asked questions on puberty, behaviour, emotional, social and school functioning.
Lead researcher, Dr Fiona Mensah, says the study provides new evidence of pre-existing and persistent early childhood differences in socio-emotional well being amongst children who experience early puberty.
“There is a heightened risk for behaviour and emotional problems during puberty; and children who reach puberty earlier than their peers have more of these difficulties in adolescence.”
Professor George Patton says the study supports a ‘life course’ hypothesis.
“Understanding what lies behind early puberty may also tell us much about the origins of emotional and behavioural problems of children and adolescents.”
The study was published in the Journal of Adolescent Health.

There has been a good deal of interest in a question about whether very early adolescent heavy cannabis use may cause ongoing problems even when someone stops cannabis use. The early teens are a time of rapid brain development involving those parts involved in emotional control. Studies in rats have suggested large doses of cannabinoids (the active ingredients in cannabis) may alter longer terms patterns of anxiety. Other studies in humans have raised a question about early cannabis users have reduced intelligence later in adulthood. We found that in our study of two thousand young Victorians a two-fold higher rate of anxiety problems in the later twenties even where an individual was no longer using cannabis. We could not account for it by other aspects of an individual’s lifestyle or their earlier history of mental health problems. It is consistent with a view that heavy (at least weekly) early teen cannabis use does increase the risks for later anxiety problems.

Professor Susan Sawyer was interviewed for the Melbourne Voice by Annie Rahilly and talked about the new research being done by Professor Patton and his team at the Centre for Adolescent Health looking at the health of future generations.

Sylvia Kauer investigated the efficacy of a self-monitoring mobile application on depressive symptoms in adolescents. Using structural equation modelling she found mobile phones increased emotional self-awareness which then decreased depressive symptoms. Her research suggests that self-monitoring applications should be considered for young people at risk of mental health problems. Sylvia greatly appreciates the support of Australian Rotary Health which funded her PhD through the Ian Scott Scholarship. Sylvia is now a PostDoc Research Fellow at the Department of General Practice, University of Melbourne on the LINK project, developing and evaluating a e-portal to facilitate help-seeking in young people.
Congratulations to Rosemary Sasse, Rony Duncan, Rosalie Aroni and Susan Sawyer who have just had a paper published in the Journal of Adolescent Health about confidentiality with adolescents and why parents worry about it.
Dr Duncan and Professor Sawyer’s previous research had shown that parents had mixed views about confidential health discussions for their teenage children. In this new study, the research team was interested in finding out more about what was behind parents’ views. To this end, Rosemary Sasse conducted a series of interviews with parents of adolescents to hear their opinions regarding confidential consultations for adolescents with doctors (without parents present). Parents’ views seemed to be influenced by 2 key factors: (1) how much they trust health professionals; and (2) how they view their role as a parent.
The findings should help health professionals to understand why parents might be reluctant to step out of the consultation and how they can talk to both parents and young people in order to help everyone to feel comfortable with confidential consultations. Only in this way can adolescents receive the developmentally-appropriate care that is so vital for them.

A new report released by the Centre for Adolescent Health provides the answers to important questions about the quality of care provided to adolescents within a children’s hospital. This report is in response to previous work that demonstrated that the health issues affecting adolescents require different responses from the hospital as a system (as compared to younger children) and that the hospital needs to engage more effectively with young people themselves as they mature (not just with their parents), in order to promote young people’s growing capacity for self-management. On behalf of the RCH, the Centre for Adolescent Health set out to explore:
(i) what are the indicators of adolescent friendly healthcare for adolescent patients in a hospital setting?
(ii) how do we measure adolescent friendly healthcare in a hospital setting? and
(iii) what is the adolescent friendliness of the health care provided by the RCH, as rated by our adolescent patients and their parents?
The report outlines the processes undertaken and shares the results of the first ever representative survey of adolescent patients and their families at a children’s hospital.
