A definition of the Big Five personality trait Neuroticism, a description of what people who are high/low on the trait would be like, two behaviors or traits that the new trait should be correlated with, any precursors or causes of the trait (where does it come from? Why do people become neurotic or conscientious?), and important outcomes associated with the trait (look for work outcomes, interpersonal outcomes, and even behavioral health outcomes).
Traits are habitual patterns of behavior, thought and emotions. They vary from person to person but are relatively stable over time. In psychology, a number of human personality traits are studied, such as self-esteem, perfectionism, neuroticism, rigidity, etc.
Neuroticism is typically exhibited in the form of enhanced feelings/emotions such as anxiety, anger, guilt, depression, etc. Correspondingly, a person who scores low on Neuroticism will be more emotionally stable, relaxed and social, as compared to a person scoring high on Neuroticism. A neurotic person perceives mundane activities as threatening and trivial problems appear menacing to them.
The very symptoms of neuroticism (anxiety, envy, jealousy, etc.) can be used to measure or characterize Neuroticism.
Freud stated that past emotional experiences are a precursor to neuroticism, which stems from the inability of the individual to let go of those unpleasant experiences. These past experiences interfere with the individual's ability to deal with the present.
Jung believed that two conflicting psychic events/contents (a conscious and an unconscious) will lead to neuroticism.
People suffering from Neuroticism are typically shy and self-conscious, traits that will inhibit interpersonal relations and affect the ability to work properly in any given workplace. Neuroticism may also lead to substance (drug and alcohol) abuse issues.
