Standard mental health tests may be inaccurate for highly intelligent people
Key Points:
- A new study published in Intelligence reveals that common mental health surveys lose accuracy when applied to highly intelligent individuals, challenging previous conclusions about the link between intelligence and emotional well-being.
- Researchers found that standard depression and distress questionnaires do not measure psychological conditions consistently at high intelligence levels due to a lack of measurement invariance, meaning test items correlate less strongly with overall mental health in gifted people.
- Initial analysis suggested a U-shaped relationship where mental health improves with intelligence up to a point before declining, but this pattern may be a statistical artifact caused by the tests' failure to function equivalently across intelligence levels.
- The study highlights the need for developing new mental health assessment tools tailored to highly intelligent populations and calls for further research to explore whether similar
