The serotonin transporter (5-HTT) regulates serotonergic neurotransmission and is thought to influence emotion. A 5-HTT-linked polymorphic region (5-HTTLPR) has two common variants, short (s) and long (l). We previously found population and within-family associations between the lower-expressing s allele and neuroticism, a trait related to anxiety, hostility, and depression, on a standard measu...

INTRODUCTION The serotonergic neurotransmitter system is closely linked to depression and personality traits. It is not known if selective serotonin reuptake inhibitors (SSRI) have an effect on neuroticism that is independent of their effect on depression. Healthy individuals with a genetic liability for depression represent a group of particular interest when investigating if intervention with...

However, an alternative dimensional viewpoint is that PDs are maladaptive expressions of general personality traits. The dimensional perspective postulates that personality pathology exists at a more extrem...

Previous studies have implicated antisocial personality disorder in criminal behavior, but little is known about the association between "normal" personality dimensions and arrest. We investigated the relationships between these personality dimensions and prior arrest in a sample of adults participating in a longitudinal epidemiological study. Between 1993 and 1999, psychiatrists re-examined su...

To investigate whether personality traits affect the rate of decline of gray matter volume, we analyzed the relationships between personality traits and the annual rate of changes of gray matter volume in 274 healthy community dwelling subjects with a large age range by applying a longitudinal design over 6 years, using brain magnetic resonance images (MRI) and the Revised NEO Personality Inven...

In the present research, the authors examined the data quality and replicability of the revised NEO personality inventory (NEO-PI-R) factor structure in a sample that varied in ethnicity, socioeconomic status, and literacy.
