Independent observers also rated the videotaped interactions. Trait PA was positively related to both participant and observer evaluations of interaction quality.

Both PA and NA were positively related to the number of interactions in which participants engaged, and the amount of time spent engaged in social contact, although different types of social encounters produced these relations.

Research has revealed that some people report experiencing greater amounts of positive emotions than do others and are typically referred to as high-positive-affect (or high-PA) individuals.
