Neuroticism
A Big Five personality trait measuring emotional instability, anxiety, moodiness, and stress reactivity. High scorers experience more negative emotions; low scorers are emotionally stable and calm.
Neuroticism is the Big Five dimension most strongly linked to mental health. It reflects the tendency to experience negative emotions — anxiety, sadness, anger, and self-consciousness — more frequently and intensely.
High Neuroticism individuals have a more reactive nervous system. They worry more, feel stressed more easily, and take longer to recover from negative experiences. They're also more self-aware and empathetic (high sensitivity to emotional cues). Low Neuroticism individuals are emotionally stable, calm under pressure, and less affected by setbacks.
Neuroticism is the strongest personality predictor of depression (r=0.50-0.60), anxiety disorders (r=0.50), and burnout risk. However, moderate Neuroticism provides advantages: heightened threat detection, empathy, and motivation to avoid mistakes.
