Negative affectivity

Negative affectivity (NA) is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, and fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm.

Individuals differ in negative emotional reactivity. Trait negative affectivity roughly corresponds to the dominant personality factor of anxiety/neuroticism that is found within the Big Five personality traits as emotional stability. The Big Five are characterized as openness, conscientiousness, extraversion, agreeableness, and neuroticism. Neuroticism can plague an individual with severe mood swings, frequent sadness, worry, and being easily disturbed, and predicts the development and onset of all "common mental disorders. Research shows that negative affectivity relates to different classes of variables: Self-reported stress and (poor) coping skills, health complaints, and frequency of unpleasant events. Weight gain and mental health complaints are often experienced as well.

People who express high negative affectivity view themselves and a variety of aspects of the world around them in generally negative terms. Negative affectivity is strongly related to life satisfaction. Individuals high in negative affect will exhibit, on average, higher levels of distress, anxiety, and dissatisfaction, and tend to focus on the unpleasant aspects of themselves, the world, the future, and other people, and also evoke more negative life events. The similarities between these affective traits and life satisfaction have led some researchers to view both positive and negative affect with life satisfaction as specific indicators of the broader construct of subjective well-being.

Negative affect arousal mechanisms can induce negative affective states as evidenced by a study conducted by Stanley S. Seidner on negative arousal and white noise. The study quantified reactions from Mexican and Puerto Rican participants in response to the devaluation of speakers from other ethnic origins.
