We are requesting access to the age data on these variables at age 15-16 in order to undertake initial descriptive analyses of the all of the behaviours separately, followed by more complex analyses exploring the extent to which and ways in which these behaviours cluster using multiple regression, adjustment for missing data using multiple imputation techniques, and use of various latent variable techniques. The work is being undertaken as part of the DECIPHer programme of work on multiple risk behaviours in adolescence.

The work is directed by a multi disciplinary group of researchers, led by Prof Rona Campbell and Prof Matt Hickman, with involvement from Dr Ruth Kipping, Dr Jon Heron and Dr Kate Tilling. Dr Georgie MacArthur (Clinical Lecturer/public health trainee) will undertake the initial descriptive analysis and we are in the process of employing a Research Assistant to work full-time on this analysis. We would hope that both Georgie MacArthur and the RA would have direct access to the data and would be supported by Jon Heron and hence there would be no need to incur the time (and therefore costs) of a data buddy to facilitate the use of the data.

Following the initial analysis of data at ages 15-16, we will submit a separate application to the ALSPAC Executive for antecedent characteristics or exposures earlier in life; risk behaviours at other ages during adolescence; and outcomes such as education, morbidity and mortality.
