  abstract = {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.}
