The Suicidal Ideation Scale is a tool used to measure an individual’s thoughts and attitudes towards suicide. It is a self-report measure that consists of a number of items, each of which are rated on a point scale from “definitely not true” to “definitely true.” The scale was developed in order to assess an individual’s level of suicidality, as well as to predict future suicide attempts.
The scale has been found to be a reliable and valid measure of suicidality, and has been used in both clinical and research settings.
If you or someone you know is struggling with suicidal thoughts, it is important to seek professional help. If you are in the United States, you can call the National Suicide Prevention Lifeline at 1-800-273-TALK (8255) to speak with a trained crisis counselor, or call 911.
What Is The Suicidal Ideation Scale?
The Suicidal Ideation Scale (SIS) is a measure of thoughts, feelings, and behaviors related to suicide. It is used to assess the severity of suicidality and to track changes in suicidal ideation over time. While there are a number of scales in use, below we’ll talk about the most common.
Some of the different types include:
- The Nurses’ Global Assessment of Suicide Risk
- The Beck Scale for Suicide Ideation
- Columbia Suicide Severity Rating Scale
- Suicidal Affect–Behavior–Cognition Scale
The SIS often consists of 19, 21 or other amounts of items that are usually rated on a 4 or 5 point scale from 0 (not at all) to 4 (very much). The items cover a range of topics related to suicide, including thoughts about death or dying, making plans for suicide, and attempting suicide.
Generally, the total score on the SIS ranges from 76-84, with higher scores indicating more severe suicide ideation. Scores of 0-19 are considered low risk, 20-34 are moderate risk, and 35 or above are high risk.
The SIS can be used with adults or adolescents aged 13 years and older. It takes about 5-10 minutes to complete. The scale generally has good reliability and validity. Studies have shown that it is sensitive to changes in suicidal ideation over time and can discriminate between those who are at risk for suicide and those who are not.
If you are concerned that someone you know may be considering suicide, the SIS can be a helpful tool in assessing the severity of their thoughts and feelings. If you are worried about your own suicidal thoughts and feelings, the SIS can also be a useful way to track changes over time.
The Different Types Of Suicidal Ideation
There are different types of suicidal ideation, and the Suicide Ideation Scale can help to identify them. Some people experience brief periods of suicidal ideation, while others have more chronic thoughts about suicide.
Some people may have what is called passive suicidal ideation, which means that they think about death in general terms without specifically wanting to die themselves.
Others may have active suicidal ideation, where they actively think about ways to kill themselves and make plans to do so.
Still others may have what is called mixed suicidal ideation, which means that they have both passive and active thoughts about suicide.
Finally, there are those who have what is called suicidal intent, where they not only think about killing themselves but also take steps to do so.
The Benefits And Drawbacks Of The Suicidal Ideation Scale
The SIS can help clinicians to identify individuals at high risk for suicide, so that they can receive appropriate interventions and support. The SIS is also useful for research purposes, and can also help researchers to study the relationship between thoughts, feelings, and behaviors related to suicide.
But there are some limitations to consider when using this scale. First, the scale is self reported. This means people can lie on the test to appear less suicidal than they actually are.
Second, the SIS does not assess all aspects of suicidality. It only assesses suicidal ideation, not actual plans or attempts. Second, the SIS may not be sensitive enough to detect changes in suicidal ideation over time. This is especially a concern when using the SIS with populations who are at high risk for suicide (e.g., adolescents).
Despite these limitations, the SIS remains a valuable tool for assessing suicidality in research and clinical settings.

FAQs About What Is The Suicidal Ideation Scale?
Q: What is the suicidal ideation scale?
The suicidal ideation scale is a standardized clinical assessment tool used to measure the presence, severity, and intensity of a person’s thoughts about suicide. It helps mental health professionals evaluate whether someone is experiencing passive thoughts about death, active plans to end their life, or has made preparatory steps. Common versions include the Beck Scale for Suicide Ideation and the Columbia-Suicide Severity Rating Scale.
Q: What are the different types of suicidal ideation scales?
The most widely used scales include the Columbia-Suicide Severity Rating Scale (C-SSRS), which uses yes/no questions to categorize risk levels; the Beck Scale for Suicide Ideation (BSSI), a 19-item self-report measuring severity; the Nurses’ Global Assessment of Suicide Risk; and the Suicidal Affect-Behavior-Cognition Scale. Each assesses different aspects of suicidal thoughts and behaviors.
Q: How is the suicidal ideation scale scored?
Scoring varies by scale. The Beck Scale uses 19 items rated 0–3, with higher totals indicating greater severity. The C-SSRS does not produce a single number — it categorizes individuals into low, moderate, or high risk based on the presence of specific thoughts and behaviors. Clinicians use these scores to determine the appropriate level of intervention, from outpatient therapy to immediate crisis care.
Q: What is the difference between passive and active suicidal ideation?
Passive suicidal ideation involves thoughts about wanting to die or wishing to disappear without a specific plan or intent to act — for example, “I wish I could go to sleep and never wake up.” Active suicidal ideation involves having a specific plan, intent, or means to end one’s life. Both are serious and warrant professional attention, but active ideation requires immediate intervention.
Q: What are the warning signs of suicidal ideation?
Warning signs include talking about wanting to die or being a burden to others, withdrawing from friends and family, giving away personal belongings, saying goodbye to loved ones, extreme mood swings or sudden calmness after depression, increased alcohol or drug use, researching methods of self-harm, hopelessness about the future, and reckless or self-destructive behavior.
Q: What are the risk factors for suicidal ideation?
Key risk factors include a previous suicide attempt, a family history of suicide, mental health conditions (depression, bipolar disorder, PTSD, anxiety), substance use disorders, chronic physical pain or illness, recent major loss (death, divorce, job loss), financial hardship, social isolation, history of trauma or abuse, and easy access to lethal means such as firearms or medications.
Q: Can the suicidal ideation scale predict suicide?
The suicidal ideation scale is designed to assess current risk level — not to predict with certainty whether someone will attempt suicide. Higher scores indicate greater severity and a higher need for intervention, but suicide is complex and influenced by many factors beyond what any single scale can capture. The scales are most valuable as clinical screening tools that guide treatment decisions and safety planning.
Q: How is suicidal ideation treated?
Suicidal ideation is treatable with professional care. Treatment typically includes safety planning (identifying coping strategies and emergency contacts), psychotherapy such as Cognitive Behavioral Therapy (CBT) or Dialectical Behavior Therapy (DBT), medication (antidepressants or anti-anxiety drugs to address underlying conditions), and — for more severe cases — inpatient or residential treatment programs that provide 24-hour stabilization and support.
Q: What is the connection between addiction and suicidal ideation?
Substance use disorders and suicidal ideation are strongly linked. Addiction impairs judgment, increases impulsivity, worsens depression and anxiety, and can create feelings of hopelessness and isolation — all major risk factors for suicide. Research shows that people with substance use disorders are approximately 5–10 times more likely to die by suicide than the general population. Treating both conditions together through dual diagnosis programs produces the best outcomes.
Q: Where can I get help for suicidal thoughts and addiction?
If you are in immediate crisis, call 988 (Suicide & Crisis Lifeline) or 911. For ongoing treatment of suicidal ideation alongside substance use disorder, ARIA in West Palm Beach, Florida offers individualized dual diagnosis programs that treat both mental health and addiction simultaneously. Contact ARIA at (844) 973-2611 to discuss treatment options including therapy, medication management, and inpatient care.
