AAS Suicide Research & Data Analysis 4 ā Questions and Answers
Question 1: Which demographic group in the United States consistently shows the highest age-adjusted suicide rate according to CDC data?
- Middle-aged White males (45ā64) (Correct answer)
- Adolescent females (15ā19)
- Elderly Black males (75+)
- Young adult Hispanic females (20ā24)
Correct answer: Middle-aged White males (45ā64)
Middle-aged White males have consistently shown some of the highest suicide rates in the US, particularly in rural areas, driving a broad public health concern.
Question 2: What is the primary purpose of a 'sentinel surveillance' system in suicide public health monitoring?
- To collect in-depth data from selected sites rather than attempting complete population coverage (Correct answer)
- To monitor every suicide attempt that reaches an emergency department nationwide
- To provide real-time notification to law enforcement when a suicide occurs
- To replace death certificate data with more accurate medical examiner records
Correct answer: To collect in-depth data from selected sites rather than attempting complete population coverage
Sentinel surveillance uses strategically selected reporting sites to provide timely, detailed data on trends and risk factors without the cost of universal population surveillance.
Question 3: In meta-analyses of suicide risk factors, what does a Forest plot primarily display?
- Effect size estimates and confidence intervals from individual studies alongside a pooled summary estimate (Correct answer)
- Publication bias as measured by funnel plot asymmetry across studies
- Heterogeneity statistics such as I² across included studies
- The chronological timeline of studies from oldest to most recent
Correct answer: Effect size estimates and confidence intervals from individual studies alongside a pooled summary estimate
A Forest plot visually presents each study's effect size with its 95% confidence interval and combines them into a diamond representing the pooled effect estimate.
Question 4: The concept of 'lethality' in suicide attempt research most accurately refers to which characteristic?
- The medical severity of injury or potential for death caused by the attempt method (Correct answer)
- The subjective intent of the person to die at the time of the attempt
- The rescue probability given where and when the attempt occurred
- The frequency with which the specific method results in death across populations
Correct answer: The medical severity of injury or potential for death caused by the attempt method
Lethality refers to the objective medical danger posed by the method used, such as degree of tissue damage or physiological disruption, independent of intent.
Question 5: Which finding from the literature on contagion and suicide clusters is best supported by empirical evidence?
- Exposure to a peer's suicide increases short-term risk among socially connected adolescents (Correct answer)
- Media coverage of celebrity suicides has no measurable effect on population suicide rates
- Suicide clusters occur exclusively in institutional settings such as schools and prisons
- Contagion effects are limited to individuals with pre-existing mental disorders
Correct answer: Exposure to a peer's suicide increases short-term risk among socially connected adolescents
Research consistently shows that exposure to a peer's suicideāespecially in adolescent social networksāelevates short-term suicidal behavior among connected individuals.
Question 6: What does 'positive predictive value' (PPV) mean in the context of a suicide risk screening tool?
- The proportion of individuals who screen positive and actually go on to die by suicide or make an attempt (Correct answer)
- The proportion of true suicide cases that the tool correctly identifies as high risk
- The overall accuracy of the tool across all true positives and true negatives
- The likelihood ratio of a positive screen result given confirmed high-risk status
Correct answer: The proportion of individuals who screen positive and actually go on to die by suicide or make an attempt
PPV indicates how often a positive screening result is a true positiveācritical for suicide prediction tools because very low PPV means most flagged individuals are not actually at risk.
Question 7: In Hawton's framework for studying self-harm, what distinguishes 'self-harm' from 'suicide attempt' as research categories?
- Self-harm is defined functionally by intent to harm without necessarily intending to die, while a suicide attempt includes intent to die (Correct answer)
- Self-harm refers exclusively to non-suicidal cutting, while suicide attempts involve ingestion of substances
- Self-harm applies only to adolescents, whereas suicide attempt is used for adults in the literature
- Self-harm is measured by medical severity, while suicide attempt is measured by psychological intent alone
Correct answer: Self-harm is defined functionally by intent to harm without necessarily intending to die, while a suicide attempt includes intent to die
Hawton's framework uses intent as the key differentiator: self-harm may or may not involve suicidal intent, while suicide attempt specifically involves intent to end one's life.
