Linguistic and Personological Features of Suicidality In Bulimia: A Study of Memoirs

Bulimia and suicide ideation and behavior co-occur at rates that warrant investigation. This study applied a corpus linguistic tool to examine memoirs of people self-identifying as having been diagnosed with bulimia. A log likelihood statistic was used to determine word usage rates in the memoir corpus compared to known norm rates. Besides p values, effect sizes (i.e., Bayesian Information Criterion) were reported for all inferential analyses. The study found that memoirs of people identifying as having been diagnosed with bulimia included differences in various linguistic processes and psychological processes. In addition, the usage rates of words associated with the core dimensions of Interpersonal-psychological theory of suicide were described.
