The aim of this study was to examine the relationship between the narcissism, perfectionism, Big5 and achievement striving, and to determine whether and in what way these constructs predict the achievement striving. A total of 202 participants (162 female and 40 male), attending some of the faculties of the University of Zagreb, participated in the research. Participants filled in The Multidimensional scale of perfectionism Frost et al. (1990; Zubčić & Vulić-Prtorić, 2008), the Achievement Scale (O'Neil et al., 1986), the Inventory of Pathological Narcissism (Pincus et al., 2009) and Big-Five markers (Goldberg, 2001) were used to operationalize the constructs. Data collection was conducted online via a survey form. The results showed that there was a statistically significant positive correlation between the pursuit of achievement, perfectionism, narcissism and their subscales. Also, a significant correlation was found between adaptive perfectionism and all scales of the Big5, maladaptive perfectionism, extraversion, conscientiousness and emotional stability, vulnerable narcissism, emotional stability, extraversion and conscientiousness, and between grandiose narcissism, extraversion and intellect. A significant negative correlation was found between agreeableness and achievement striving. Furthermore, hierarchical regression analysis showed statistically significant positive predictors of achievement striving, grandiosity, adaptive and maladaptive perfectionism, while agreeableness showed as statistically significant negative predictor.
