| Anger, Anxiety and Sadness are constructed from the averaged daily frequency (across users) of words in the tweets that can be matched to the lexical field of anger, anxiety and sadness, respectively. |
| Mental Health is constructed from the averaged daily frequency (across users) of all words that are matched to the lexical field of anger, anxiety and sadness in all tweets. |
