Depressive symptomatology may be reflected in the language used by possible depressive profiles (PDP). This paper investigates to what extent symptoms of depression are manifested in Brazilian Portuguese narrative texts, and whether these can be used to identify relevant linguistic clues related to PDP. Moreover, the relation between these symptoms and PDP is explored, characterising the lexical, syntactic, and psycholinguistic aspects of texts produced by PDP. We found that texts associated with PDPs differed in some of these characteristics from non-PDP texts. The interactions between symptoms and PDP can also shed light on patterns of communication differentiation and the relationship between them. The results of this paper can help to characterise and understand the indicators that can be used to train more bespoke and accurate large language models.
