The consistently elevated usage of first-person personal singular pronouns and the consistently diminished usage of first-person personal plural pronouns are in line with previous studies linking this pattern with a low level of social integration, which has been related to suicide according to different theories.

Background and Objectives: Text analysis software like "Linguistic Inquiry and Word Count" (LIWC) has been used for the analysis of suicide notes and suicidal texts in English. This is the first analysis of suicide notes using this method in Spanish and, as far as we know, its first application to suicide notes in Europe. To compare the sociodemographic and forensic characteristics of a consecutive sample of suicide victims studying the differences between those who left suicidal note and those who did not. To study a sample of suicidal notes from Spain using LIWC, comparing it's linguistic features by gender, age and environment. Methods: 144 consecutive suicide cases were analyzed. 23 suicide notes obtained from this sample were processed using LIWC, the results were compared by gender, age and environment of the author. Results: People who left suicide notes were younger than non-writers; more frequently single, divorced or widowed and emotional troubles were reported as frequent triggers. Suicide notes written by women were significantly longer, had more emotional content, tentative expressions, denials, pronouns in first person plural and verbs in past and future tenses. Urban cases showed higher emotional expression and word complexity whereas rural cases showed a higher use of social words. Conclusions: Our study shows some differences between people who left suicide note and those who didn't and confirms the LIWC ability to detect differences in suicidal speech by gender and by the rural/ urban background of its authors.

SPAIN CHILEABSTRACT -Background and Objectives: Studying suicide notes is a strong methodology in suicidology and one of the most relevant theoretical frameworks is the Interpersonal Theory of Suicide proposed by Joiner.This study analyzed 80 suicide notes collected in Chile searching for the risk factors proposed by the theory and its implications. The clinical and sociodemographic characteristics of the notes' authors were analyzed too.Methods: The suicide notes were classified according to the presence or absence of the suicide risk factors proposed by the Interpersonal Theory of Suicide and were analyzed linguistically with the Linguistic Inquiry and Word Count program.Results: One or both interpersonal risk factors indicated by the theory were identified in 60% of the notes. The "lack of belonging" factor was the most common risk factor, and various linguistic profiles in the suicide notes were found according to the presence or absence of this factor.Conclusions: We confirmed the relevance of the interpersonal risk factors proposed as issues present in a high percentage of notes and found linguistic differences according to its presence or absence in the suicide notes.

The aim of this work was to analyze Marilyn Monroe's “Fragments” using a computerized method for text analysis: Linguistic Inquiry and Word Count (LIWC). This software has been used in recent years to examine suicide notes, letters and poems in order to characterize the quantitative linguistic features of suicidal texts. Selected texts were grouped into four periods of similar word count and then processed with LIWC. Kruskal-Wallis Test was applied for comparison of means between periods and for each of the 80 LIWC output scores. Significant differences (p < 0.05) were found in only five categories: use of pronouns, use of words longer than six letters, use of the third person of plural, use of swear words and use of expressions related with religion.Our results do not support the findings described in previous studies of writings of persons who committed suicide.
