Age differences in hostility among middle-aged and older adults.

Multiple measures of hostility were administered to middle-aged and older volunteers. There was a positive association between age and self-report measures reflecting hostile beliefs about others, including cynicism and suspiciousness. There was a weak inverse relationship between age and self-report measures of the overt expression of anger and aggression, but no association between age and measures of covert hostility was found. There was a positive relationship between age and an assessment of hostile behavior that was based on the respondent's interaction style during an interview. The magnitude of these age trends did not differ between men (n = 50) and women (n = 75). These findings illustrate the multidimensional nature of hostility. They also have practical implications for older people because hostility is associated with psychological well-being and has been shown to have consequences for health and longevity.

Hostility, job attitudes, and workplace deviance: test of a multilevel model.

The authors tested a model, inspired by affective events theory (H. M. Weiss & R. Cropanzano, 1996), that examines the dynamic nature of emotions at work, work attitudes, and workplace deviance. Sixty-four employees completed daily surveys over 3 weeks, reporting their mood, job satisfaction, perceived interpersonal treatment, and deviance. Supervisors and significant others also evaluated employees' workplace deviance and trait hostility, respectively. Over half of the total variance in workplace deviance was within-individual, and this intraindividual variance was predicted by momentary hostility, interpersonal justice, and job satisfaction. Moreover, trait hostility moderated the interpersonal justice-state hostility relation such that perceived injustice was more strongly related to state hostility for individuals high in trait hostility.

Mock trial jury decisions as a function of adolescent juror guilt and hostility.

A fictitious court case involving child abuse was presented to 277 male adolescent jurors (138 college freshmen, means age = 19.25 years, 139 junior high school males, means age = 13.47 years) in an effort to determine if the tendency to deal harshly with alleged criminals is dependent upon certain personality characteristics of adolescent jurors. The Mosher Hostility Guilt Scale and the Siegel Manifest Hostility Scale were used to detect the presence of such trends. The results indicate that older adolescents attributed more of the responsibility for the crime to the defendant and administered less severe sentences than younger adolescent jurors. Hostility guilt and manifest hostility levels were not significantly related to attribution of responsibility for a criminal act; however, Ss scoring high in hostility guilt tended to give significantly shorter sentences, while Ss scoring high in manifest hostility tended to give longer sentences. Implications for adolescent peer practices are discussed.

Manifest hostility may affect habituation of cardiovascular reactivity in blacks.

In a study of cardiovascular reactivity to dietary manipulation of sodium and calcium, we pretested 30 young black normotensive males who were equally divided by positive and negative parental histories of hypertension with a 12-item anger questionnaire we devised and the Cook-Medley Hostility, Manifest Hostility, Overcontrolled Hostility, and Inhibited Hostility scales of the Minnesota Multiphasic Personality Inventory. Contrary to expectations, we found no correlation of resting blood pressure or cardiovascular reactivity to repeated mental demands with the two measures of inhibited hostility. We did, however, find resistance to habituation of cardiovascular reactivity in subjects with high Manifest Hostility and positive family histories of essential hypertension. Our findings suggest that vulnerability to hypertension may be revealed by the perseveration of blood pressure reactivity to repeated mental challenge. We propose that the perseveration of blood pressure reactivity is a disinhibitory phenomenon caused by a difficulty in the management of multiple inhibitory demands that disrupts the natural course of habituation and could be an important etiologic factor in essential hypertension.

Hostility in smokers with past major depressive disorder: relation to smoking patterns, reasons for quitting, and cessation outcomes.

We examined trait hostility in 85 participants in a clinical trial of cessation treatment for smokers with a history of major depressive disorder. Consistent with hypotheses, trait hostility, as indexed by the Cook-Medley Hostility Scale, was associated with greater smoking in social situations, greater expectations of being evaluated negatively by others because of smoking, and stronger extrinsic social reasons for quitting. Greater hostility was associated with significantly lower odds of smoking abstinence after treatment. Hostility was not associated significantly with smoking to manage negative affect, nor did it predict change in negative mood during treatment. Results suggest hostility may play an important role in smoking motivation and cessation outcomes among smokers with past major depression.

Hostility predicts recurrent events among postmenopausal women with coronary heart disease.

Psychosocial characteristics may be associated with an increased risk of coronary heart disease (CHD). Whether hostility predicts recurrent coronary events is unknown. A total of 792 women in the Heart and Estrogen/progestin Replacement Study (HERS) were evaluated prospectively to determine the role of hostility as a risk factor for secondary CHD events (nonfatal myocardial infarction and CHD death). The mean age of study participants was 67 years, and the average length of follow-up was 4.1 years. The study was conducted between 1993 and 1998, and all study sites were in the United States. High Cook-Medley hostility scores were associated with greater body mass index (p = 0.01) and higher levels of serum triglycerides (p = 0.05), and they were inversely associated with high density lipoprotein cholesterol (p = 0.04), self-rated general health (p < 0.001), age (p = 0.05), and education (p = 0.001). Compared with women in the lowest hostility score quartile, women in the highest quartile were twice as likely to have had a myocardial infarction (relative hazard = 2.03, 95% confidence interval: 1.02, 4.01). The relation between hostility and CHD events was not mediated or confounded by the biologic, behavioral, and social risk factors studied. In this study, hostility was found to be an independent risk factor for recurrent CHD events in postmenopausal women.

Hostility and the educational gradient in health. The mediating role of health-related behaviours.

BACKGROUND: The aim was to study hostility as a factor intermediate in the association between educational level and health. METHODS: 1997 cross-sectional data from the Dutch GLOBE study (1675 men and 1819 women) was used. The analyses distinguishes between direct effects of hostility on health, and indirect effects, which are through health-related behaviours. The latter indicates that hostile people may be at risk of adverse health, because they engage in unhealthy behaviours. Data were analysed with logistic regression techniques. RESULTS: Among men and women, the odds of less than good health was higher in lower educational groups. A substantial part of the educational gradient in health could be ascribed to the intermediate effects of hostility. Among both men and women, the direct effects of hostility were more important than indirect effects. CONCLUSION: Results suggest that interventions should be aimed at the prevention of the development of hostility. Additionally, interventions aimed at the reduction of health damaging behaviours among adults may lead to a reduction of socio-economic inequalities in health.

Hostility and recovery from melancholia.

Twenty inpatients suffering from major depressive illness with melancholia were administered the hostility subscale of the Kellner Symptom Questionnaire and Paykel's Clinical Interview for Depression before and after treatment with amitriptyline. A matched control group of normal subjects had the same assessments at two points in time. Hostility decreased and friendliness increased in depressives after amitriptyline; upon recovery, there were no significant differences in hostility between depressed patients and control subjects, whereas such differences were striking during the illness. Patients who had reported losses before onset of illness rated themselves as more friendly than the other depressives; their hostility did not significantly decrease with recovery. The results suggest that hostility improves with the treatment of depression; life events appear to influence the degree of hostility in depressive illness as well as the response to treatment.

The Cook-Medley hostility scale: item content and ability to predict survival.

Previous studies have identified the MMPI-based Cook and Medley hostility scale (Ho) as a predictor of health outcomes. To achieve a better understanding of the construct measured by this scale, Ho items were classified on an a priori basis. Six subsets were identified: Cynicism, Hostile Attributions, Hostile Affect, Aggressive Responding, Social Avoidance, and Other. Study 1 examined the correlations of these subsets with scales of the NEO Personality Inventory in two samples of undergraduates. Good convergent and discriminant validity were demonstrated, but there was some evidence that items in the Social Avoidance and Other categories reflect constructs other than hostility. Study 2 examined the ability of the Ho scale and the item subsets to predict the 1985 survival of 118 lawyers who had completed the MMPI in 1956 and 1957. As in previous studies, those with high scores had poorer survival (chi 2 = 6.37, p = 0.012). Unlike previous studies, the relation between Ho scores and survival was linear. Cynicism, Hostile Affect, and Aggressive Responding subsets were related to survival, whereas the other subsets were not. The sum of the three predictive subsets, with a chi 2 of 9.45 (p = 0.002), was a better predictor than the full Ho scale, suggesting that it may be possible to refine the scale and achieve an even more effective measure of those aspects of hostility that are deleterious to health.

Components of hostility as predictors of sudden death and myocardial infarction in the Multiple Risk Factor Intervention Trial.

We tested the hypothesis that hostility is associated with increased relative risk (RR) for coronary death and nonfatal myocardial infarction among participants in the prospective Multiple Risk Factor Intervention Trial (MRFIT). Cases (N = 192) were compared with matched controls (N = 384) on a variety of behavioral characteristics associated with the Type A behavior pattern (TABP), including three different but interrelated components of hostility. Logistic regression analyses revealed that only two of the eight TABP attributes analyzed on the overall sample were significant. Only total Potential for Hostility, when dichotomized into "low" and "high" categories, and the antagonistic interpersonal component of hostility (Stylistic Hostility) had positive unadjusted associations with coronary heart disease (CHD) incidence (RR = 1.7, p = 0.003; and RR = 1.5, p = 0.016, respectively). The global TABP and related paralinguistic attributes were not significantly related to CHD incidence. After adjustment for the traditional risk factors of age, serum cholesterol, blood pressure, and cigarette smoking, only dichotomous Potential for Hostility showed a significant relative risk (RR = 1.5, p = 0.032). Ordinal logistic regression revealed a nonsignificant effect.(ABSTRACT TRUNCATED AT 250 WORDS)

Cortisol excretion in high and low cynically hostile men.

Cynical hostility as measured by the Cook and Medley Hostility (Ho) Scale has been found in some studies to be associated with increased risk of life-threatening illness. Previous laboratory studies of cardiovascular reactivity have been consistent with the general hypothesis that increased physiological responsiveness is one possible mechanism underlying the association between hostility and health. The present study extended this previous research by evaluating urinary cortisol excretion during routine daily activities in a sample of high and low cynically hostile young men. Although high and low Ho groups did not differ in their cortisol excretion upon awakening, the high Ho group displayed more than twice the increase in cortisol excretion during daytime hours as that occurring among low hostile men. This difference dissipated during the evening hours. Results are discussed in terms of possible physiological mechanisms linking hostility and health.

Ambulatory blood pressure and heart rate in paramedics: effects of cynical hostility and defensiveness.

Ambulatory blood pressure and heart rate responses were obtained in 33 male paramedics during a 24-hour work shift to examine the effects of episodes of occupational stress on cardiovascular reactivity and subjective reports of stress. The aim of this study was to determine how individual differences in cynical hostility and defensiveness interacted with situational demands to affect cardiovascular responses in a natural setting. Defensiveness was found to interact significantly with cynical hostility in predicting subjects' heart rate responses in different work contexts. Specifically, in a hospital setting involving interpersonal conflict, subjects who were high in both defensiveness and hostility showed heart rate responses approximately 10 bpm higher than subjects who were high in hostility but low in defensiveness. The same pattern of relationships was obtained for diastolic blood pressure. High and low hostile subjects were also found to differ from each other in their daily mean levels of ambulatory blood pressure during awake and sleep periods. These findings obtained in a natural setting lend further support to the significance of cynical hostility for cardiovascular reactivity. The results for defensiveness suggest the need for further research on the role of conflicting attitudes in the pathophysiology of cardiovascular diseases.

Hostility and myocardial ischemia in coronary artery disease patients: evaluation by gender and ischemic index.

Two studies assess relationships of hostility to extent and severity of exercise-induced cardiac ischemia and daily life ischemia in patients with coronary artery disease (CAD). CAD patients (N = 80) who underwent exercise tomographic thallium testing to assess myocardial perfusion completed the Cook-Medley Hostility Inventory (Ho). A Composite Hostility (Chost) score obtained from the Ho scale was also used. Statistically controlling for the effects of gender in the full sample (N = 80), Chost was positively correlated with severity of perfusion defects (r = 0.22, p < 0.05). This relationship was nonsignificant in the 63 male patients, but was significant among women (N = 17, r = 0.42, p < 0.05) and among middle-aged men (less than 60 years, N = 17, r = 0.55, p < 0.05). In an overlapping sample of 42 CAD patients with ischemia (ST-segment depression > or = 1 mm) during 24 to 48 hours of ambulatory electrocardiographic monitoring, after controlling for gender, both Ho and Chost were positively correlated with total minutes of ischemia (r = 0.28 and r = 0.29, respectively, p < 0.05). In addition, there was a significant gender x hostility interaction, with stronger relationships with hostility evident for women. Results from these two studies indicate that in patients with coronary artery disease, hostility traits are significantly correlated with extent of daily life ischemia and with severity of exercise-induced myocardial ischemia. These relationships appear to be significant among female and middle aged male patients, but may be less evident among older male patients.

Self-reported hostility and suicidal acts, accidents, and accidental deaths: a prospective study of 21,443 adults aged 25 to 59.

The association of self-reported hostility with morbidity and mortality due to external causes, including suicidal acts, was analyzed in 10,586 Finnish men and 10,857 Finnish women aged 24 to 59 years. Hostility was assessed from self-ratings on irritability, ease of anger-arousal, and argumentativeness. Three groups, low (33.6% of subjects), intermediate (50.6%), and extreme (15.9%), were formed from the self-reported hostility scores. A 6-year mortality follow-up yielded 76 violent deaths among men and 11 among women. A 4-year morbidity follow-up found 399 hospitalizations due to external causes among men and 169 among women. Among men, the risk ratio between the highest and lowest hostility groups was 1.51 (95% confidence interval, 1.16-1.96) for all events due to external causes and 3.6 (95% confidence interval, 1.63-7.89) for suicidal behavior, when effects of age, marital status, social status, and self-reported alcohol use were controlled in a multivariate model. No association was observed between traffic-related injuries and hostility. Hostility did not predict accidents or accidental deaths or suicidal behavior among women.

A test of the psychosocial vulnerability and health behavior models of hostility: results from an 11-year follow-up study of Mexican Americans.

Previous research has shown that interpersonal conflict and depression are cross-sectionally associated with hostility. Our objective was to determine whether hostility is longitudinally predictive of interpersonal distress and depression and to replicate previous research that suggests that hostility is a risk factor for other health behaviors (e.g., smoking and excessive alcohol use) and psychosocial health problems. We use data from the youngest generation of a three-generation, 11-year follow-up study of Mexican Americans, that represent 251 Mexican Americans between the ages of 18 and 42 years. Our indicator of hostility was the irritability subscale from the Buss-Durkee Hostility Inventory. After statistically controlling for marital status, language acculturation, education, age, and sex, irritability was found to predict subsequent heavy drinking, somatic symptoms associated with depression, psychosomatic symptoms, infectious disease, divorce, marital separation, ending a serious nonmarital relationship, not being married at the follow-up, and more negative feelings associated with divorce, marital separation, and ending a serious relationship. Our research supports theory and research suggesting that hostility is predictive of physical symptoms, poor health habits, and interpersonal conflict.

The relationship between hostility and beta-adrenergic receptor physiology in health young males.

OBJECTIVE: We examined the relationship between hostility and mononuclear leukocyte (MNL) beta-adrenergic receptor function in a sample of young healthy males. METHOD: Thirty subjects were selected for having scored above 20 (N = 11) and below 14 (N = 19) on the Cook-Medley Hostility (Ho) scale. MNL beta-adrenergic receptor function was characterized in terms of receptor density (Bmax) and ligand-binding affinity (Kd) in homogenized cells, and intracellular cyclic adenosine monophosphate (cAMP) responses to saline, isoproterenol, and forskolin in whole cells. Subjects also completed the Multidimensional Anger Inventory (MAI), which assesses dimensions of anger. RESULTS: Relative to men with low Ho scores, men with Ho scores above 20 showed lower receptor number and greater forskolin-stimulated cAMP. Moreover, high hostile men reported a greater frequency of anger, longer duration of anger, more frequent brooding, and a hostile outlook. CONCLUSIONS: These data indicate that adrenergic receptor down-regulation is associated with hostility. This association may be linked to hostile persons' propensity for excessive and prolonged neuroendocrine responses to either psychological stressors or the experience of chronic stress associated with frequent and prolonged bouts of anger.

Hostility, sodium consumption, and cardiovascular response to interpersonal stress.

OBJECTIVE: Previous studies have reported poorer health behaviors in high vs. low hostile subjects. The role of stress in these observed differences has not been explored although interpersonal stress does increase cardiovascular response in high hostiles. Given evidence that stress may induce increased salt-intake, this study examined the role of hostility and interpersonal stress in increasing sodium consumption in addition to cardiovascular reactivity. METHOD: Sixty-nine male undergraduates were categorized into high (HiHo) and low hostile (LoHo) groups based on Buss-Durkee Hostility Inventory scores. Subjects engaged in either a math task with harassment, math task without harassment, or a control/rest condition. Sodium intake was assessed posttask by having subjects ingest a sodium-free soup that was presented with a saltshaker without any comments. Cardiovascular measures were also recorded. RESULTS: HiHo subjects consumed more salt than LoHo subjects irrespective of experimental condition. HiHo subjects who were harassed also exhibited greater cardiac output, systolic blood pressure, and forearm blood flow than did HiHo nonharassed, HiHo control, or LoHo subjects. CONCLUSION: HiHo subjects exhibited increased salt-intake, although evidence for stress-induced salt-intake was not obtained. Nonetheless, the combination of salt and stress may contribute to the cardiovascular hyperreactivity and risk for cardiovascular disease in hostile individuals.

Hostility and the metabolic syndrome in older males: the normative aging study.

OBJECTIVE: Several studies have shown that hostility, as measured by the Minnesota Multiphasic Personality Inventory-derived Cook-Medley Hostility Scale (Ho), is positively associated with several cardiovascular risk factors, possibly accounting for the relationship between Ho scores and cardiovascular mortality. This study was undertaken to examine associations between hostility and cardiovascular risk factors representing the metabolic syndrome in 1,081 older men who participated in the Normative Aging Study. METHODS: Subjects included men who completed the Minnesota Multiphasic Personality Inventory in 1986 and who participated in a subsequent laboratory examination within 1 to 4 years. Total and subscale Ho scores were computed, and associations with anthropometric data, cigarette smoking, dietary information, serum lipids, blood pressure, and fasting glucose and insulin levels were examined. RESULTS: The total Ho score was positively associated with waist/hip ratio, body mass index, total caloric intake, fasting insulin level, and serum triglycerides. The Ho score was inversely related to education and high-density lipoprotein cholesterol concentration. Path analysis also suggested that the effects of hostility on insulin, triglycerides, and high-density lipoprotein cholesterol were mediated by its effects on body mass index and waist/hip ratio, which, in turn, exerted their effects on lipids and blood pressure through insulin. CONCLUSIONS: The results are consistent with those of prior research and also suggest that, in older men, hostility may be associated with a pattern of obesity, central adiposity, and insulin resistance, which can exert effects on blood pressure and serum lipids. Furthermore, effects of hostility on the metabolic syndrome appear to be mediated by body mass index and waist/hip ratio.
