Neuroticism

Neuroticism (or emotional stability) is a trait in many models within personality theory, but there is a lot of disagreement on its definition. Some define it as a tendency for quick arousal when stimulated and slow relaxation from arousal, especially in concern to negative emotional arousal; others define it as emotional instability and negativity or maladjustment, in contrast to emotional stability and positivity, or good adjustment. Others yet define it as lack of self-control, poor ability to manage psychological stress, and a tendency to complain.

Neuroticism is one of the Big Five higher-order personality traits in the study of psychology. Individuals who score high on neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, guilt, depressed mood, and loneliness. People who are neurotic respond worse to stressors and are more likely to interpret ordinary situations as threatening and minor frustrations as hopelessly difficult.

They are often self-conscious and shy, and they may have trouble controlling urges and delaying gratification. Persons with a high neuroticism index are at risk for the development and onset of common mental disorders, such as mood disorders, anxiety disorders, and substance use disorder, symptoms of which had traditionally been called neuroses. Individuals who score low in neuroticism tend to be more emotionally stable and less reactive to stress. They tend to be calm, even-tempered, and less likely to feel tense or rattled. Although they are low in negative emotion, they are not necessarily high on positive emotion.
