Pre-registration with John Marsden

In this episode of Addiction Audio, Professor John Marsden talks about the role of pre-registration in increasing research transparency. He addresses the anxieties that people can have about pre-registration and talks about how it’s really not that difficult or daunting.


Professor Marsden talks gets into the detail of pre-registration; when to register, how to register and the importance of planning for – and dealing with – missing data. He covers how plans change during any research project and how to respond when they do. The importance of pre-registration also includes qualitative research and Professor Marsden talks about the need for more qualitative and observational studies to be pre-registered.


“We’re really trying to encourage people to just plan, adapt if you need to, change if you have to – but just have a clear narrative about that – and everyone benefits. It means that what was done is much more reproducible.”


Professor John Marsden is the Editor-in-Chief of the journal Addiction. He is Professor of Addiction psychology at the Addictions Department, the Institute of Psychiatry, Psychology and Neuroscience, Kings College London.
