Question 1 · Behavioural science, Preclinical
In elderly men followed for 15 years, which psychological factor was associated with lower cardiovascular mortality after controlling for cardiovascular risk factors and depressive symptoms?
- A. Anger and hostility
- B. Chronic work stress
- C. Type A personality
- D. Optimism
- E. Psychological distress
Show the answer and explanation
Answer: D. Optimism
Optimism was associated with a lower risk of cardiovascular mortality in elderly men during 15 years of follow-up. The association remained after controlling for cardiovascular risk factors and depressive symptoms.
Why the other options are wrong
- A. Anger and hostility: Anger and hostility were associated with increased CHD events in healthy populations and poor prognosis in CHD populations.
- B. Chronic work stress: Work stress (high demand, low control) is a chronic stressor.
- C. Type A personality: Type A personality is hostile, pressured behaviour contributing to CVD.
- E. Psychological distress: Psychological distress shows a dose-response association with cardiovascular disease death across the full range of distress.
Key point: Optimism was associated with lower cardiovascular mortality independent of risk factors and depressive symptoms.
