Scale for Suicidal Ideation
The Scale for Suicide Ideation (SSI) is a 21-item, interviewer-administered scale that measures the current intensity of patients’ specific attitudes, behaviors, and plans to commit suicide on the day of the interview and during the time period that they were most suicidal. The first 5 items are screeners (wish to live, wish to die, and desire to attempt suicide), followed by 14 items to assess suicidal risk factors. The last 2 items capture previous suicide attempts. The respondent is first asked all questions about their suicidal ideation on the day of the interview and then queried about the most severe point of suicidal ideation.
Each item is rated on a 3-point scale ranging from 0 to 2 according to suicidal intensity. The SSI is scored by adding up the ratings (0-2) from the first 19 items.
This protocol includes questions that can potentially identify respondents who are at risk of suicide. Investigators implementing this protocol should consider developing a risk management plan specific to their study to ensure the safety of participants.
