The Suicide Upsetness Assessment was used to measure the phenomenological experience of emotional upset during active states of suicide ideation. 49 inpatients with a history of suicide-related behaviours completed a battery of assessments during their hospital stay. After the research team reviewed theories regarding suicidality, 6 separate categories related to suicide ideation were created, which were then subdivided into groups. Chi-square & Fisher Exact Tests provided information regarding characteristics of emotional upset most often associated with suicide-related behaviours. Emotional upset is a heterogeneous construct in suicidal individuals, the properties of which may provide for a more thorough risk assessment. (26 refs.)
