ABSTRACT
Aims: In this study, the probable relationships between the types and factors of the Five Factor Model of Personality (FFM), which is a contemporary personality model, and the Nine Types Temperament Model (NTTM), which is a new temperament model, were investigated. Separately, the power of some of the types of NTTM to predict the dimensions of FFM was evaluated, as well. Study Design: Cross-sectional survey. Place and Duration of Study: Bezmialem Vakıf University (BVU) Psychiatry Outpatient Clinic (Turkey) between June 2013 and January 2014. Methodology: The sampling of the research consists of 247 healthy volunteers. Materials of the research include the Five-Factor Personality Inventory (FFPI) and The Nine Type Temperament Scale (NTTS). Results: All types of NTTM showed a significant correlation along with at least one of the FFPI factors at the level of 0.40 and above. Furthermore, the types of NTTM were determined to have predicted the dimensions of the FFPI by 34% and above. Conclusion: Significant correlations were found between the types of NTTM and the FFM factors. The results are discussed in regards to how the differences in the conceptual approach can be understood and the area of use between NTTM and FFM.
ABSTRACT
Objective: This study aimed to evaluate the relationship between oxidative stress markers and cognitive functions and domains of psychosocial functioning in bipolar disorder. Methods: Oxidative stress markers, cognitive functions, and domains of psychosocial functioning were evaluated in 51 patients with bipolar disorder who were in remission. Correlation analyses between these parameters were calculated with data controlled for duration of illness and number of episodes. Results: There was no statistically significant correlation between oxidative stress markers and cognitive functions. In terms of psychosocial functioning, significant correlations were found between malondialdehyde and sense of stigmatization (r = -0.502); household activities and superoxide dismutase (r = 0.501); participation in social activities and nitric oxide (r = 0.414); hobbies and leisure time activities and total glutathione (r = -0.567), superoxide dismutase (r = 0.667), and neurotrophin 4 (r = 0.450); and taking initiative and self-sufficiency and superoxide dismutase (r = 0.597). There was no correlation between other domains of psychosocial functioning and oxidative stress markers. Conclusion: These results imply that oxidative stress markers do not appear to correlate clearly with cognitive impairment and reduced psychosocial functioning. However, there were some associations between selected oxidative markers and activity-oriented functional markers. This may represent a true negative association, or may be an artifact of oxidative stress being a state rather than a trait marker. .
