The role of perfectionism in daily self-esteem, attachment, and negative affect.

This study of university students (64 men, 99 women) examined the role of self-critical (SC) and personal standards (PS) higher order dimensions of perfectionism in daily self-esteem, attachment, and negative affect. Participants completed questionnaires at the end of the day for 7 consecutive days. Trait and situational influences were found in the daily reports of self-esteem, attachment, and affect. In contrast to PS perfectionism, SC perfectionism was strongly related to aggregated daily reports of low self-esteem, attachment fears (fear of closeness, fear of dependency, fear of loss), and negative affect as well as instability indexes of daily self-esteem, attachment, and negative affect. Multilevel modeling indicated that both SC and PS perfectionists were emotionally reactive to decreases in self-esteem, whereas only SC perfectionists were emotionally reactive to increases in fear of closeness with others. These results demonstrate the dispositional and moderating influences of perfectionism dimensions on daily self-esteem, attachment, and negative affect.
