| dc.description.abstract | Various dimensions of perfectionism are proposed, but are seldom integrated. This research develops and tests an integrative theory of perfectionism. Theory predicts personality traits (perfectionistic concerns, but not perfectionistic strivings) precede and predict changes in characteristic adaptations (perfectionistic self-presentation and perfectionism cognitions). Theory also predicts characteristic adaptations precede and predict decreases in subjective well-being (SWB), and are associated with a particular patterned form of perfectionistic narrative identity (i.e., heightened agency and lowered communion). This research tests this integrative theory. A sample of 127 emerging adults (ages 18-25) transitioning to university for the first time was recruited (78% female; 81% Caucasian). A 3-wave, 130-day longitudinal design with quantitative and qualitative components was used. Participants completed questionnaire measures of perfectionism and subjective well-being at all waves, and completed semi-structured life story interviews at Waves 1 and 3. Interviews were transcribed and coded for themes of agency (i.e., themes of achievement, status, power, and self-mastery) and communion (i.e., themes of love, dialogue, caring, and community). Results are presented in Chapters 2, 4 and 5. In Chapter 2, perfectionistic concerns led to increased perfectionistic self-presentation, which in turn led to decreases in SWB. In contrast, perfectionistic strivings did not predict longitudinal change in perfectionistic self-presentation or SWB. These findings supported hypotheses. In Chapter 4, perfectionistic concerns and perfectionism cognitions were positively correlated with agency. Perfectionism cognitions mediated the relationship between perfectionistic concerns and agency. A qualitative thematic analysis revealed themes of agency focused on performance-related concerns, with undertones of self-doubt and unrealistic high standards. These findings supported hypotheses. In Chapter 5, perfectionistic concerns and SWB were unrelated to communion, contrary to expectations. However, themes of communion exhibited good inter-rater reliability, test-retest reliability, and face validity. Hypotheses regarding communion were not supported. Overall, most hypotheses were supported. By conceptualizing perfectionistic personality as a dynamic, multifaceted, and integrated system, there are numerous implications for developmental, clinical, and personality psychology. These implications, along with the strengths and limitations of this study, are discussed. | en_US |
