The aim of this study was to analyse the relationships between polymorphisms in four candidate genes (AR, DAT1, DRD2, and COMT) and aggression in men from a traditional society of East African pastoralists, the Datoga. Buss and Perry's Aggression Questionnaire was used to measure aggression. The number of CAG repeats in the AR gene was negatively correlated with physical aggression, anger, and ...

BACKGROUND   Previous studies have linked marital conflict, parenting, and externalizing problems in early childhood. However, these studies have not examined whether genes account for these links nor have they examined whether contextual factors such as parental personality or financial distress might account for links between marital conflict and parenting. We used an adoption design to allow...

Hostility is associated with substantial mental and physical health consequences. Population-based data regarding the nature and longitudinal course of hostility in U. S. veterans are scarce. We analyzed data from 2157 U. S. veterans who participated in the National Health and Resilience in Veterans Study, a nationally representative, prospective cohort study of U. S. veterans. We identified th...

Hostility is a personality trait associated with increased risk of coronary heart disease. No study has reported the association between hostility and antioxidants, which may be mediators for atherosclerosis. CARDIA (Coronary Artery Risk Development in Young Adults) Study participants were 3,579 men and women 18-30 years of age in 1985-1986. Serum carotenoids and tocopherols were measured at ye...

In this study, we applied multivariate genetic analysis, a generalization of factor analysis and behavior genetic analysis, to responses to items of the Psychoticism scale of the Eysenck Personality Questionnaire by 2,903 adult same-sex Australian twin pairs. Item loadings on genetic, shared environmental, and nonshared environmental common and specific factors were estimated. The genetic facto...

This study assessed the extent of women’s hostility toward men and men’s hostility toward women among 18,093 university students who participated in the International Dating Violence Study in 27 nations. Results revealed a high prevalence of low-level hostility among both sexes. We also tested the theory that inequality generates antagonism, hypothesizing that there would be less hostility betw...

OBJECTIVE To compare the effects of haloperidol, amisulpride, olanzapine, quetiapine, and ziprasidone on hostility in first-episode schizophrenia, schizoaffective disorder, or schizophreniform disorder. METHOD We used the data acquired in the European First-Episode Schizophrenia Trial, an open, randomized trial (conducted in 14 countries) comparing 5 antipsychotic drugs in 498 patients aged 1...

OBJECTIVE We investigated the moderating relationship of hostility on emotional and physiological arousal due to acute anger provocation; stress reactivity and recovery were measured. METHOD Forty-five participants completed a measure of trait hostility (CMHQ) and performed a mental arithmetic (serial 7s) task while receiving scripted comments at set intervals designed to provoke anger (haras...

This study examined the effects of hostility on blood pressure (BP) during the early morning hours before awakening and several hours afterward. Our objective was to determine whether the pattern of BP change and the slope of the morning BP surge were related to hostility. The subjects were 32 patients with a history of Stage 1 hypertension. The morning surge in BP was derived from ambulatory B...

The aim of the present study was to assess the role of empathy in mediating the association between difficulties in emotion regulation and hostility. Three hundred and sixty young Italian adults (220 women and 140 men) were enrolled in the study. Psychopathological assessments included the Difficulties in Emotion Regulation Scale (DERS), the Interpersonal Reactivity Index and the Buss-Durkee Ho...
