The ups and downs of social life: Within-person variations in daily status and inclusion differentially predict self-regard and interpersonal behavior.

This research replicates at the within-person level empirical links previously found at the between-person level. The results suggest that narcissism operates chiefly as a hierometer (tracking status and regulating assertiveness), whereas self-esteem additionally operates as a sociometer (also tracking inclusion and regulating affiliativeness).
