Using diagnosis file for machine learning approaches

Hi there. Thanks a lot for creating this incredible dataset. I am applying support vector classification (SVC) and regression methods to UCLA dataset to predict the new observations for the three mental disorders.
Thus, which diagnosis table and information may I use for that analysis?
I see plenty of behavioral tasks and diagnostic contributions included in files and tables, but I’m not sure which file is more suitable for using as symptoms and diagnosis in the machine learning process.
I would appreciate your comments on this.
Thank you.
