3-Step Theory of suicide (THREE-ST)

Ontology Info

Field	Value
Acronyme	THREE-ST
Description	This ontology contains classes, sub-classes, and relationships that map onto the 3-Step Theory of suicide (3ST). The classes represent the four factors that make up the central tenets of the theory: 1) psychological pain, 2) hopelessness, 3) connectedness, and 4) capacity for suicide. The instances of each subclass are terms that were found in VA clinical notes and indicate presence or absence of the associated 3ST factor. The terms are intended to be used in an NLP pipeline to extract 3ST information from clinical progress notes.<br>Psychological pain, hopelessness, and capacity for suicide are major risk factors for suicide, whereas connectedness is a protective factor. In brief, the theory holds that suicide only occurs if pain and hopelessness outweigh connectedness and only then if the capacity for suicide is present.
