Intensity of Suicidal Ideation (Continuum)
November 21, 2014
A questionnaire to measure the degree of suicidal ideation.
Suicidal ideation can indicate an increased risk for suicidal attempts. This measure can be used to determine levels of suicidal risk and aid in making clinical decisions about care. In contrast to the PhenX measure Classification of Suicidal Ideation and Suicidal Behavior, which distinguishes and classifies suicidal ideation and behavior separately, this measure considers suicidal ideation existing as a continuous scale within a single construct.
