Researchers have identified interpretable lexical features in spoken language that are associated with the severity of major depressive disorder (MDD). Using data from the RADAR-MDD study, they found that reductions in word count, use of first-person plural pronouns, and positive word frequency correlated with higher symptom severity. While these associations were largely consistent across the UK, Netherlands, and Spain, the study noted limitations including a skewed age and gender demographic and a lack of NLP tools for non-English languages, suggesting further research with more diverse samples is needed.
