abstract="Aim. Identification of the relationship between suicidal risk and features of the text written by patients with endogenous mental diseases. <br><br>METHODS. The study involved 58 people-patients with endogenous mental diseases who were being treated at the MHRC clinic. All patients were asked to write an essay on the topic &quot;I, others, the world&quot;. To analyze the semantic and syntactic structure of utterances, the method of relational-situational analysis and the method of frequency lexical analysis using the PLATIn analyzer were used. All patients completed the following methods: (1) SCL-90-R symptomatic questionnaire (Symptom Check List-90-Revised); (2) the Iowa game problem -- the expectation-result model of Expectancy-valence is used, which introduces parameters for probabilistic modeling of decision-making: &quot;attention to win-loss&quot;, &quot;learning-forgetting&quot;, &quot;impulsivity-determinism&quot;; (3) The Barratt impulsivity scale [10]; (4) the five-factor personality questionnaire, the Bass-Perry questionnaire. <br><br>RESULTS. The results of the Spearman correlation analysis showed statistically significant correlations between the severity of suicide risk (from the SCL-90 questionnaire) and the parameters of texts obtained using computer analysis, with the parameters of the Expectation-valence model of the Iowa game problem, the Barratt impulsivity scale, the Bass-Perry questionnaire, and emotionality in the five-factor personality questionnaire. <br><br>CONCLUSIONS. There were found the features of the text that are associated with increased suicide risk: increased use of past tense verbs in texts; higher productivity -- increase in the number of sentences and words in the text while reducing the length of the words and decrease of the number of infinitives; the increase in the coefficient of Trager; reduced vocabulary positive rational assessment and mental activities; increase vocabulary of asthenic negative emotions. The analysis of the relationship between suicidal risk and personal characteristics revealed characteristics similar to those shown in the texts: a high level of hostility, increased emotionality, increased impulsivity and a pronounced momentary effect. © 2020, Eco-Vector LLC.
