This study extended previous theory and cross-sectional research on narcissism-depression associations by taking a longitudinal approach to understanding how pathological narcissism relates to shame-proneness, aspects of perfectionism, and depression among a sample of 235 undergraduate students. Findings revealed that pathological narcissism was associated with various depressive symptoms (e.g., general depression, loss of interest, lack of positive affect) concurrently, and was uniquely related to the severity and variability of anhedonic loss of interest over 8 weeks. Although pathological narcissism did not moderate shame-depression associations, modest interaction effects were found between aspects of perfectionism and depression. The clinical implication of these findings and directions for future studies are discussed.
