Positive affectivity (PA) and negative affectivity (NA) are nearly independent of each other;[REF] it is possible for a person to be high in both PA and NA, high in one and low in the other, or low in both.
Happiness, a feeling of well-being, and high levels of self-esteem are often associated with high levels of positive affectivity, but they are each influenced by negative affectivity as well [REF].
