Which of the following mental disorders were listed as conferring greater suicide risk?

• A. Depression
• B. PTSD
• C. Bipolar disorder
• D. All of the above

Answer: (D)

Multiple mental health conditions can raise suicide risk, and each of the disorders listed is associated with a higher likelihood of suicidal thoughts or behavior. Depression is a well-established risk factor because persistent hopelessness, anhedonia, and functional impairment can lead to planning or attempts. PTSD adds risk through chronic distress, intrusive memories, hyperarousal, sleep problems, and often co-occurring problems like substance misuse, all of which heighten vulnerability. Bipolar disorder also carries substantial risk, especially during depressive or mixed states when mood instability, impulsivity, and despair are prominent.

Because each condition independently contributes to risk, the option that includes all three captures the true picture: depression, PTSD, and bipolar disorder collectively confer greater suicide risk. Choosing any single disorder would miss the added risk present in the others. Remember that overall risk is shaped by multiple factors, but the question focuses on these listed diagnoses, each of which elevates risk.
