Description: This study compared how extraversion, neuroticism, and extraversion × neuroticism are related to processing of pleasant and unpleasant emotional information as predicted by Eysenck's, Gray's, and Newman's theories. Initially, the participants' levels of extraversion (as measured by the sociability subscale) and neuroticism were assessed with Eysenck's Personality Inventory. They were then tested individually. After completing a questionnaire of current positive and negative moods, they completed three tasks measuring processing of pleasant, unpleasant, and also neutral information. The results showed that extraversion was associated positively with the processing of pleasant information, while neuroticism was associated positively with the processing of unpleasant information. These findings support predictions from Eysenck's theory. © 2002 John Wiley & Sons, Ltd.

Description: Gray's reinforcement sensitivity theory (RST) suggests that personality reflects the operation of the behavioural inhibition system (BIS), and the behavioural approach system (BAS). Several measures have been proposed for the BAS and BIS. Based on ratings by 358 adults of the BAS measures of EPI impulsivity, Carver and White's (CW) BAS and GRAPES reward expectancy, and the BIS related measures of STAI-anxiety, CW BIS and GRAPES punishment expectancy, this study used confirmatory factor analysis (CFA) to examine their convergent and discriminant validities. CFA was also used to examine the relations of the BAS and BIS factors with latent extraversion and neuroticism. The results of this study indicated support for the convergent validities of all the BAS and BIS measures. With the exception of GRAPES reward expectancy, there was some support for their discriminant validities also. All BIS factors correlated negatively with extraversion and positively with neuroticism. Among the BAS measures, only EPI impulsivity correlated positively with both extraversion and neuroticism. These findings support their concurrent validities. © 2004 Published by Elsevier Ltd.

Description: This study examined how the presence and severity of Generalised Anxiety Disorder (GAD) were associated with trait anxiety, neuroticism, and extraversion. A total of 40 individuals with a diagnosis of GAD and 40 non-GAD control participants completed self-rating questionnaires covering GAD symptoms, trait anxiety, neuroticism, and extraversion. Results indicated that the GAD group had significantly higher scores for neuroticism and trait anxiety, and significantly lower scores for extraversion than the control group. Among individuals with GAD, the severity of GAD was positively associated with trait anxiety and neuroticism, and negatively with extraversion. Also, the additional variance contributed by neuroticism and extraversion over trait anxiety was significant, while trait anxiety made no additional contribution over that made by neuroticism and extraversion. The interaction of neuroticism and extraversion failed to contribute to both the presence and the severity of GAD. These findings are discussed in terms of how the personality models of Eysenck, Gray, and Newman are related to the presence and severity of GAD. © 2002 Elsevier Science Ltd. All rights reserved.

Description: This paper examines the effect of the Big Five personality traits on job satisfaction and subjective wellbeing (SWB). The paper also examines the mediating role of job satisfaction on the Big Five-SWB relationship. Data were collected from a sample of 818 urban employees from five Chinese cities: Harbin, Changchun, Shenyang, Dalian, and Fushun. All the study variables were measured with well-established multi-item scales that have been validated both in English-speaking populations and in China. The study found only extraversion to have an effect on job satisfaction, suggesting that there could be cultural difference in the relationships between the Big Five and job satisfaction in China and in the West. The study found that three factors in the Big Fiveextraversion, conscientiousness, and neuroticismhave an effect on SWB. This finding is similar to findings in the West, suggesting convergence in the relationship between the Big Five and SWB in different cultural contexts. The research found that only the relationship between extraversion and SWB is partially mediated by job satisfaction, implying that the effect of the Big Five on SWB is mainly direct, rather than indirect via job satisfaction. The study also found that extraversion was the strongest predictor of both job satisfaction and SWB. This finding implies that extraversion could be more important than other factors in the Big Five in predicting job satisfaction and SWB in a high collectivism and high power distance country such as China. The research findings are discussed in the Chinese cultural context. The study also offers suggestions on the directions for future research.

Description: Background: Antidepressant efficacy in people with major depressive disorder remains modest, yet identifying treatment-predictive neurobiological markers may improve outcomes. While disruptions in functional connectivity within and between large-scale brain networks predict poorer treatment outcome, it is unclear whether higher trait neuroticism, which has been associated with generally poorer outcomes, contributes to these disruptions and to antidepressant-specific treatment outcomes. Here, we used whole-brain functional connectivity analysis to identify a neural connectomic signature of neuroticism and tested whether this signature predicted antidepressant treatment outcome. Methods: Participants were 226 adults with major depressive disorder and 68 healthy control subjects who underwent functional magnetic resonance imaging and were assessed on clinical features at baseline. Participants with major depressive disorder were then randomized to 1 of 3 commonly prescribed antidepressants and after 8 weeks completed a second functional magnetic resonance imaging and were reassessed for depressive symptom remission/response. Baseline intrinsic functional connectivity between each pair of 436 brain regions was analyzed using network-based statistics to identify connectomic features associated with neuroticism. Features were then assessed on their ability to predict treatment outcome and whether they changed after 8 weeks of treatment. Results: Higher baseline neuroticism was associated with greater connectivity within and between the salience, executive control, and somatomotor brain networks. Greater connectivity across these networks predicted poorer treatment outcome that was not mediated by baseline neuroticism, and connectivity strength decreased after antidepressant treatment. Conclusions: Our findings demonstrate that neuroticism is associated with organization of intrinsic neural networks that predict treatment outcome, elucidating its biological underpinnings and opportunity for better treatment personalization. © 2021 Society of Biological Psychiatry
