The Suicide Intent Scale developed by A.T. BECK in 1974 is the only scale that is only interested in evaluating the suicide attempt that has just taken place. It responds to the professional recommendations for Hospital care of adolescents and young adults after a suicide attempt. This is a hetero-questionnaire applicable to suicides and is used to assess the intensity of the patient's desire for death at the time of his suicide attempt. It has a predictive value of the risk of subsequent successful suicide (but not of the risk of a new suicide attempt). The initial version was developed by A.T. BECK in 1974 and has 20 questions, divided into 3 sections. It was revised by D. W. PIERCE in 1977, who made it a 12-question version, divided into 3 sections:
The circumstances of the suicide attempt (6 questions)
Comments reported by the patient (self-report) (4 questions)
Two questions on physician-assessed lethality
The total suicidal intentionality score is the sum of the 12 questions.
This scale also has the semiological interest of structuring the interview with the suicide.
The total suicidal intentionality score is the sum of the 12 questions. It varies from 0 to 25:
- 0-3: Low intentionality.
- 4-10: Average intentionality.
- 11-25: High intentionality.
