The current study investigated the associations among trait perfectionism, perfectionistic selfpresentation, negative social feedback, interpersonal rumination, depressive symptoms, and social anxiety. New measures of negative social feedback and interpersonal rumination were used to evaluate their relevance to the social aspects of perfectionism and their roles in distress. A sample of 155 undergraduate students completed the Multidimensional Perfectionism Scale, the Perfectionistic SelfPresentation Scale, the Social Feedback Questionnaire, Rumination About an Interpersonal Offense, and measures of depressive symptoms and social anxiety. The results confirmed that socially prescribed perfectionism and perfectionistic self-presentation were associated significantly with negative social feedback and rumination following interpersonal events (i.e., being hurt, humiliated, mistreated). Also, depressive symptoms and social anxiety were associated significantly with negative social feedback, interpersonal rumination, trait perfectionism, and perfectionistic self-presentation. Additional analyses indicated that negative social feedback and interpersonal rumination mediated the links between components of the perfectionism construct and distress. Overall, our findings suggest that self-reported receipt of frequent negative feedback from others and engaging in rumination about an interpersonal event play important roles in the distress experienced by certain individuals with high levels of perfectionism.
