Suicidal Ideation Attributes Scale - Modified (SIDAS-M) Diagnostic Tool

Question 1

Think about the last 4 weeks. Did you think about deliberately killing yourself?

  • Choose a HIGH number if you thought about killing yourself a lot

  • Choose a LOW number if you did not think about killing yourself much

  • If you did not think about killing yourself in the last 4 weeks: choose 0

Deliberately: on purpose, planned

Thinking about hurting yourself is not the same as thinking about killing yourself if you did not want to die

Question 2 *

Think about the last 4 weeks. How difficult was it for you to stop thinking about deliberately killing yourself?

  • Choose a HIGH number if it was hard to stop thinking about killing yourself

  • Choose a LOW number if it was easy to stop thinking about killing yourself

If something is difficult or hard it might seem like it is impossible to do
If something is
easy it does not take much effort to do it

Question 3 *

Think about the last 4 weeks. How close did you come to trying to deliberately killing yourself?

  • Choose a HIGH number if you hurt yourself on purpose in the last 4 weeks and you wanted to die by the injury

  • If you purposely tried to kill yourself in the last 4 weeks, choose 10

If you hurt yourself in the last 4 weeks, think about whether you wanted to die

Hurting yourself on purpose or by accident is not the same as trying to kill yourself if you did not want to die

Question 4 *

Think about the last 4 weeks. How often did you feel distressed or very unhappy by thoughts of killing yourself?

  • Choose a HIGH number if you have felt very unhappy by thoughts about killing yourself

  • Choose a LOW number if you have not felt very unhappy by thoughts about killing yourself

Distressed: feeling very upset

Thought: an idea, an image, a sound, or a feeling that seems to be “inside” your head

Question 5 *

Think about the last 4 weeks. Have the thoughts about killing yourself made it harder for you to do the things you normally do?

  • Choose a HIGH number if thoughts about killing yourself made it a lot harder to do the things you normally do
