What is a suicide risk assessment?

Suicide risk assessment is a structured approach used by healthcare professionals to identify individuals at risk of committing suicide. More than 700,000 people die every year by suicide, which is one person every 40 seconds. In people aged 15 to 34, it is the second cause of death after unintentional injuries; and it is also among the leading causes of death in older people. 

 Usually, prior to any suicide or attempted suicide, a person has what is known as suicidal ideation, which refers to thinking about, considering, or planning suicide. Fortunately, most people with suicidal ideation never attempt suicide, but there is no reliable way to identify those who will. The goal of suicide risk assessment is to identify individuals at risk of suicide and to implement suicide prevention strategies to reduce that risk.

What is SAD PERSONS?

SAD PERSONS is a suicide risk assessment acronym to help remember the factors that increase the risk of suicide. It was first developed as a screening tool for healthcare professionals to determine suicide risk. Nowadays, it is often used as part of a comprehensive clinical evaluation in people with suspected suicidal behavior 

What does the first “S” in SAD PERSONS mean?

The first “S” in SAD PERSONS stands for male sex. Statistics show that genetic males are three times more likely to die by suicide than genetic females, although genetic females typically report suicidal thoughts more often and undertake more non-fatal suicide attempts. 

What does the “A” in SAD PERSONS mean?

The “A” in SAD PERSONS means age younger than 19 or older than 45. Young people face specific risk factors that elevate their suicide risk, including higher rates of bullying, social media pressures, feelings of isolation, and impulsive decision-making, which can lead to self-harming behaviors without fully considering the consequences. 

On the other hand, older individuals may experience other risk factors, like extreme loneliness and lack of social support. Things like declining health and loss of independence may lead to concerns about being a burden to others, resulting in feelings of worthlessness. Finally, older individuals may have easier access to lethal means, such as firearms or poisons, making them more likely to die in suicide attempts. 

What does the “D” in SAD PERSONS mean?

The “D” in SAD PERSONS means depression. Approximately 90% of people who die by suicide have a mental health disorder, the most common of which is depression. Clinical depression is a relatively common but serious condition that interferes with someone’s day-to-day life, essentially leading to anhedonia, which is the lack of interest, enjoyment or pleasure from activities normally found enjoyable. Sometimes, this feeling is so intense that a person loses hope or meaning in life or starts believing that the world would be a better place without them. 

All individuals with depression should be asked about possible thoughts of self-harm or suicide, as there is no evidence that asking about suicidal ideation will increase suicide risk 

What does the “P” in SAD PERSONS mean?

The “P” in SAD PERSONS means previous suicide attempt. A prior self-harming or suicide attempt increases the risk of committing suicide in the future, especially in people who have not received adequate follow-up care.   

What does the “E” in SAD PERSONS mean?

The “E” in SAD PERSONS means excessive alcohol or substance use. Many people turn to alcohol or substances to cope with feelings of depression and anxiety, creating a vicious cycle of worsening mental health and substance dependence. In addition, alcohol and drugs can dampen the central nervous system, leading to impaired judgment and increased impulsivity, which increases their likelihood of taking risks that they wouldn’t normally take. 

What does the “R” in SAD PERSONS mean?

The “R” in SAD PERSONS means rational thinking loss, which means having a distorted sense of reality. This can happen in psychotic disorders like schizophrenia, where people may act on suicidal thoughts driven by false beliefs caused by delusions or hallucinations. For example, in persecutory delusions, a person may falsely believe they are being watched, harassed, or targeted by others to the point they might consider suicide as the only way to escape their perceived threats.  

What does the second “S” in SAD PERSONS mean?

The second “S” in SAD PERSONS means separated or single. The absence of close, intimate relationships is a significant risk factor for depression as it can lead to profound feelings of loneliness. Additionally, separation or divorce often involves the loss of a significant person, which can lead to an overwhelming sense of grief. 

What does the “O” in SAD PERSONS mean?

The “O” in SAD PERSONS means organized plan, which refers to having specific plans to end one's life. This may include preparatory behaviors, such as gathering means (e.g., medications, weapons, poisons) or writing a suicide note, for example. Individuals who have an organized suicide plan require urgent care to ensure their safety, which may include close monitoring or hospitalization.  

What does the “N” in SAD PERSONS mean?

The “N” in SAD PERSONS means no social support. Having meaningful relationships is a strong protective factor against suicide, as it provides emotional support and helps people deal better with life’s adversities. Suicide rates are higher amongst people with no social support as well as vulnerable or stigmatized groups who experience discrimination, such as prisoners, refugees, indigenous people, and LGBTQ+ individuals.  

What does the third “S” in SAD PERSONS mean?

The third “S” in SAD PERSONS means sickness, which refers to chronic diseases, like end-stage cancer, that can be very difficult to deal with. People with chronic illnesses may think there is no hope for improvement or recovery, which can lead to hopelessness. Being unable to participate in social activities they used to enjoy may result in loss of identity and purpose, contributing to depression. Finally, some people may need to quit their job due to illness, which may result in added financial difficulties.  

What are the most important facts to know about the SAD PERSONS acronym?

SAD PERSONS is a screening tool used to identify individuals at risk of committing suicideS stands for male Sex; A for Age younger than 19 or older than 45; D for Depression; P for Previous suicide attempt; E for Excess alcohol or substance use; R for Rational thinking loss; S for Separated or Single; O for Organized plan; N for No social support; and S for Sickness. The more risk factors an individual has, the higher the risk of suicide. Even in the absence of any risk factors, a person may decide to take their own life in moments of overwhelming life stress, which could be due to the loss of a loved one, financial crisis, or chronic illnesses, like end-stage cancer. The SAD PERSONS acronym can be used to remember the main risk factors for suicide; however, it shouldn’t replace clinical assessment by a medical professional.
