What does neuroticism measure in psychological terms?

Neuroticism primarily measures the degree of emotional stability or emotional instability in an individual. High levels of neuroticism indicate a tendency to experience negative emotions such as anxiety, depression, and moodiness, reflecting an individual's emotional resilience or vulnerability. This trait is one of the five factors in the Big Five personality theory, contributing to how individuals respond to stress and everyday challenges. People with low neuroticism are generally considered more emotionally stable, capable of handling stress effectively, and less prone to feeling negative emotions. Understanding neuroticism can provide insights into an individual's behavior and mental health, making it a critical factor in psychological assessments.
