This is the project for **The daily association between affect and alcohol use: A meta-analysis of individual participant data** Our **preregistration**, which we wrote *after* obtaining datasets included in our analyses but *before* we processed and analyzed the data, can be found under '**Registrations**'. The folder **Analysis and results**, which can be found under '**Files**' > '**Google Drive: The daily association between affect and alcohol use: A meta-analysis of individual participant data**', contains our analysis scripts as well as the R output associated with our four main analyses. Due to the large size of these models, we have not uploaded R output for sensitivity and moderator analyses - if you would like access to these files, please write a quick mail to jonas.dora.psych@gmail.com. The folder **Supplementary materials**, which can be found under '**Files**' > '**OSF Storage**', contains all supplementary materials referenced in the manuscript.
