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 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.
