Research Interests

My main research interest is focused on teenage alcohol, drug use and crime. In particular, I am interested in why some young people use cigarettes, alcohol and drugs while others do not, and why for some young people substance misuse is a transient behaviour, but for others it develops into serious social, legal and health problems. My main work in this area has been the Belfast Youth Development Study. This is an ongoing longitudinal study of adolescent drug use and crime funded by the Research and Development Office (DHSS&PS). The BYDS has tracked the development of a sample of around 4,000 young people who were aged 11 in 2001. This work has been supplemented with a number of qualitative studies looking in more detail at specific teenage substance use behaviours.  I have also undertaken analysis of the major UK survey data sets including the British Cohort Study and the British Crime Survey.   

My second research interest is in methodological development in the areas of quantitative assessment of sensitive behaviours, measurement error in longitudinal survey research, and the psychometric properties of adolescent questionnaires.
