University stu- dents (64 men; 99 women) completed questionnaires in a laboratory session and then for seven consecutive days. Results of hierarchical multiple regression analyses supported self-criticism as the most robust predic- tor of retrospective summary and aggregated daily measures of daily stress, avoidant coping, low perceived social support, negative affect, and low positive affect. Specific perfectionism components did not exhibit unique relations with maladjustment. Ó 2005 Elsevier Ltd. All rights reserved.
