Adolescents’ social cognitions and the social gradient in adolescent mental health ------------------------------------------------------------------------ **Update 15/01/21** A new folder with analysis files was added to this project. Please see the readme file for details of the files. Several 'Codebook and Data Cleaning' files were also revised to be in accordance with the latest versions of Youth Got Talent project files (though to be honest, no changes were made between this and previous versions which affected this project). The old codebook was removed and replaced rather than revised (I couldn't work out how to revise a pdf on OSF). An English version of the codebook is still in development. (Note: To view the study registration, click on 'registrations', then the only registration in that list, and then 'files'. I wrote (under 'Other Comments' in the registration) "Please see the registration file at..." but this link is incorrect.) **Update 14/10/20** This study was preregistered (on 14/10/20) using the [Secondary Data Preregistration template][1]. The codebook for the data (updated since the last project), and two syntax related to data cleaning have now been added to OSF. An English version of the codebook is in development and will be added soon. [1]: https://osf.io/x4gzt/
