What are the criteria to diagnose suicidal ideation in a patient, considering their mental health history, current symptoms, and demographics such as age, gender, and socioeconomic status?

Diagnosing Suicidal Ideation

Suicidal ideation is diagnosed through direct clinical questioning, not through screening tools or questionnaires, which have limited predictive value and should never replace a thorough clinical assessment. 1, 2

Direct Clinical Questions to Establish Diagnosis

Ask these specific questions in sequence, preferably embedded within broader depression screening 3, 2:

• "Have you ever felt so upset that you wished you were not alive or wanted to die?" 2
• "Have you ever done anything on purpose to hurt or kill yourself?" 2
• "Have you ever thought about killing yourself or wished you were dead?" 3
• "If you were to kill yourself, how would you do it?" (assesses for plan) 3

These questions do not increase suicide risk or cause suicidal thoughts in patients. 3

Distinguishing Passive from Active Suicidal Ideation

Passive Suicidal Ideation

• Thoughts of death or wishing to be dead without an active plan or intent to kill oneself 4, 5
• Examples include: "I wish I wouldn't wake up in the morning," "I don't want to be here anymore," or "Others would be better off without me" 5
• Never dismiss these statements as unimportant or manipulative—they may represent the only way a patient can ask for help 5

Active Suicidal Ideation

• Specific plan with intent and means to end one's life 4, 5
• Includes steps taken to avoid detection or prepare for death 2
• The key differentiator is the presence of intent and a formulated method 5

Essential Assessment Components Beyond the Questions

Evaluate Suicide Intent and Lethality

• Assess the balance between wish to die versus wish to live 2
• Determine if patient has taken steps to conceal behavior and avoid discovery 2
• Evaluate motivating feelings: attention-seeking, escaping intolerable situations, rejoining deceased relatives, or revenge 2
• Note: Children and adolescents systematically overestimate lethality of methods, so significant intent may exist despite non-lethal attempts 2

Mental Status Examination

Document the following 4:

• Mood state: depressed, manic, hypomanic, or mixed states 1, 2
• Anxiety level 4
• Thought content and process 4
• Presence of hopelessness (critical risk factor) 4
• Irritability, agitation, threatening violence, delusions, or hallucinations 1

Access to Lethal Means

• Firearms in the home (must be documented) 3, 2, 4
• Lethal medications available 2, 4
• Recommend immediate removal or secure storage 2

Risk Factors That Inform Diagnosis Severity

Demographic Risk Factors

• Male gender, especially ages 16-19 or older adults 1, 4
• American Indians/Alaskan Natives ages 19-24 (highest rates) 6
• Non-Hispanic white persons >75 years 6
• Hispanic females among adolescents 6
• Social isolation, living alone, runaway/homeless status 1, 2

Psychiatric and Behavioral Risk Factors

• 87% of suicide deaths involve one or more mental health disorders 6
• Depression (present in 50-79% of youth attempts; doubles odds in adults) 6
• Mania, hypomania, or mixed states, especially with comorbid substance abuse 1, 2
• Prior suicide attempts (strongest predictor) 1, 2, 4
• Substance abuse 1, 2, 6
• Pathologic Internet use >5 hours daily (strongly associated with suicidal ideation in adolescents) 3

Historical Risk Factors

• Family history of suicide 2, 6
• Serious adverse childhood events, abuse, or neglect 6
• Recent psychiatric hospitalization discharge (high-risk period) 6

Critical Pitfalls to Avoid

• Never rely solely on screening questionnaires (sensitivity 52-87%, specificity 60-85% only in high-risk populations) 3, 1
• Never discharge patients with irritability, agitation, threatening violence, delusions, or hallucinations without psychiatric evaluation 1
• Never place confidence in "no-suicide contracts"—their value is unproven and may impair therapeutic engagement 4
• Never use coercive communications like "you can't leave until you say you're not suicidal"—this encourages deceit and undermines therapeutic alliance 4

Information Sources Beyond Patient Interview

Always obtain collateral information from multiple sources 1:

• Parents or guardians 1
• School reports 1
• Other individuals close to the patient 1
• Regardless of apparent mildness of suicidal behavior, third-party information is mandatory 1

Documentation Requirements

Document the following 4:

• Estimate of suicide risk with specific influencing factors 4
• Current mental state and intent 4
• Access to lethal means and plan for removal 4
• Rationale for treatment selection or disposition decision 4
