Narcissism has been shown to be associated with a lack of trust in others, but little is known about the factors that may play a role in the tendency for narcissistic individuals to mistrust others. The present research examined whether the associations that specific narcissistic personality features had with social trust were mediated by social worldviews. A large study of Iranian community members (N = 3,446; mean age of 34.28 years) revealed that the antagonistic and neurotic aspects of narcissism had negative indirect associations with social trust through the competitive social worldview, whereas the extraverted aspect of narcissism had a positive indirect association with social trust through the competitive social worldview. In addition, the extraverted and neurotic aspects of narcissism had positive indirect associations with social trust through the dangerous social worldview. These results suggest that the extraverted, antagonistic, and neurotic aspects of narcissism diverged in their associations with social trust and that the dangerous and competitive social worldviews played important roles in these associations. Discussion will focus on the implications of these results for understanding the roles that social worldviews play in the connections between narcissism and social trust.

Background and aim: Early maladaptive schemas are effective in the formation of attitude toward substance abuse according to cognitive models. Our aim was assessment of the relationship between attitude toward substance abuse and early maladaptive schemas in medical students of "Shaheed Beheshti University of Medical Sciences". Materials and methods: This research has a correlational-descriptive method. We used the Young Schema Questionnaire-Short Form and the Drug Attitude Scale test then we selected 157 medical students by available sampling method to fill the questionnaires. Data were analyzed using the SPSS software. Results: Result indicated that there is a relationship between early maladaptive schemas and attitude toward substance abuse, in both genders. Furthermore, there are correlations between subscales of attitude toward substance test and early maladaptive schemas. The Mistrust/Abuse schema and the Unrelenting standards/Hypercriticalness schema are able to anticipate the attitude toward addiction. Conclusion: Early maladaptive schemas have a role in formation of attitude toward substance abuse. Further studies on cognitive content of attitude toward substance abuse are needed.

Background Many mental problems lead to the occurrence of physical diseases, causing worse consequences of diseases. Despite many studies in the field of personality types and types of mental disorders, this relationship and the mediating role of coping styles in cardiovascular patients are still not well known. Therefore, the present study was conducted to investigate the mediating role of coping styles in the relationship between personality types and mental disorders in cardiovascular patients. Method The present study is a cross-sectional study that was conducted on 114 cardiovascular patients at the heart center in Bushehr, Iran. The sampling method is simple random sampling. Demographic information form, MCMI-III questionnaire, NEO-FFI questionnaire, and Lazarus and Folkman coping styles questionnaire were used to collect data. Data were analyzed using SPSS 22 and Amos 24 software. Descriptive statistics methods (mean, variance and percentage), Pearson correlation, and structural equation model (SEM) were applied to analyze the data. Results The findings showed that the two variables of personality types and problem-oriented explain 15.2% of the variable of mental disorders, of which 10.7% is related to the variable of personality types and 4.5% is related to the intermediate variable of problem-oriented. Among the personality types, the neurotic personality type has the biggest role (0.632) and has a direct and significant effect on mental disorders. Also, the personality types of extroversion (-0.460), agreeableness (-0.312), and responsibility (-0.986) exert inverse and significant effects on mental disorders. Conclusion The results of the present study showed the frequency of personality disorders and other mental disorders among heart patients. Problem-oriented coping style plays a mediating role between personality types and mental disorders.
