BACKGROUND Personality with stable behavioural traits emerges in the adolescent and young adult years. Models of putatively distinct, but correlated, personality traits have been developed to describe behavioural styles including schizotypal, narcissistic, callous-unemotional, negative emotionality, antisocial and impulsivity traits. These traits have influenced the classification of their rela...

We examined measurement invariance and age-related robustness of a short 15-item Big Five Inventory (BFI-S) of personality dimensions, which is well suited for applications in large-scale multidisciplinary surveys. The BFI-S was assessed in three different interviewing conditions: computer-assisted or paper-assisted face-to-face interviewing, computer-assisted telephone interviewing, and a self...

OBJECTIVE The search for an alcoholic personality has been pursued with varying enthusiasm throughout the 20th century. This paper reviews the methodological issues, research designs and current theories relating alcoholism and personality. METHOD A selected literature search using computerised databases was ordered via the four major research design strategies: cross sectional studies, high-...

Growing interest in using personality variables in economic research leads to the question whether personality as measured by psychology is useful to predict economic behavior. Is it reasonable to expect values on personality scales to be predictive of behavior in economic games? It is undoubted that personality can influence large-scale economic outcomes. Whether personality variables can also...

The investigation of personality genetics had received much attention since the three seminal reports showing an association between genes and personality traits in the general population. Accumulating evidences suggested that personality traits have significant genetic components. Although currently available data are not enough for proof, more and more genetic variants associated with persona...

Many personality assessment inventories provide gender-specific norms to allow comparison of an individual's standing relative to others of the same gender. In some cases, this means that an identical raw score produces standardized scores that differ notably depending on whether the respondent is male or female. Thus, an important question is whether unisex-normed scores or gender-normed score...

BACKGROUND Recent studies have suggested that the age-personality relationship may be partially explained by age-related changes in social desirability. In the present study, we analyze how age affects social desirability and acquiescence, and how they affect the age-personality relationship. METHOD We used a specially designed personality test, which provides response bias and personality di...

Approximately half of the variation in wellbeing measures overlaps with variation in personality traits. Studies of non-human primate pedigrees and human twins suggest that this is due to common genetic influences. We tested whether personality polygenic scores for the NEO Five-Factor Inventory (NEO-FFI) domains and for item response theory (IRT) derived extraversion and neuroticism scores pred...

Previous results suggest that both cortisol mobilization and the error-related negativity (ERN/Ne) reflect goal engagement, i.e. the mobilization and allocation of attentional and physiological resources. Personality measures of negative affectivity have been associated both to high cortisol levels and large ERN/Ne amplitudes. However, measures of positive social adaptation and agreeableness ha...

METHODS One hundred ten patients with bipolar disorder I, 85 patients with bipolar disorder II, and 86 healthy individuals had their personality profile assessed using the Swedish universities Scales of Pe...
