Hostility-related differences in the associations between stress-induced physiological reactivity and lipid concentrations in young healthy women.

We examined the relations of fasting lipid levels to stress-induced neuroendocrine and cardiovascular responses as a function of hostility in 36 healthy young women. Participants were women who scored above 17 (n = 23) or below 12 (n = 13) on the Cook-Medley Hostility (Ho) Inventory. Lipids were determined following an overnight fast. Individuals participated in a solvable anagram task, which evoked significant physiological responses in all participants. The Ho group by total serum cholesterol (TSC) and the Ho group by low-density lipoprotein (LDL) cholesterol interactions significantly predicted heart rate (HR) and norepinephrine (Ne) responses. For high Ho women, elevations in TSC and LDL cholesterol were associated with smaller HR responses and larger Ne responses. In contrast, for low Ho women, elevations in TSC and LDL cholesterol were associated with larger HR responses and smaller Ne responses. Results also indicated a significant Ho group by TSC to high density lipoprotein (HDL) cholesterol ratio interaction for cortisol. For high Ho women, larger cortisol responses were associated with a greater TSC to HDL cholesterol ratio. For low Ho women, larger cortisol responses were associated with a smaller TSC to HDL cholesterol ratio. Lastly, higher TSC and LDL cholesterol levels were significantly associated with larger epinephrine responses. The findings suggest that stress-induced physiological responses are differentially associated with fasting lipids as a function of hostility in healthy young women.

Salience of positive and negative affect in the recognition of depression among elderly persons.

Generally, depression is thought of in terms of negative affect However, in the following paper, the contribution of positive affect (PA), as well as negative affect (NA), is demonstrated in the recognition of clinically significant depression. Affect and depression data were collected from 554 residents of a large, urban geriatric center. Statistical analyses demonstrated that both PA and NA were correlated with depression and measures of frailty, and that low PA and high NA were risk factors for depression 1 year later. Results suggest that low PA, or anhedonia, may be particularly important in diagnosing depression among older persons who may not readily report depressive symptoms such as sadness.

The relation of hostility to lipids and lipoproteins in women: evidence for the role of antagonistic hostility.

We examined the relation of antagonistic, neurotic, and cynical hostility to lipids and lipoproteins in 77 healthy women (aged 18-26) selected for having high (> 17) or low (< 12) scores on the Cook-Medley Hostility (Ho) scale. Fasting lipids were determined during the luteal phase of the menstrual cycle for oral contraceptive (OC) non-users (N = 41), and during pills 15-21 for OC users (N = 36). Factor scores for antagonistic and neurotic hostility were derived from a principal component of the Buss-Durkee Hostility Inventory, Spielberger's Anger Expression, and the NEO-Personality Inventory. High Ho scores were significantly associated with higher cholesterol. Antagonistic hostility significantly predicted cholesterol, low density lipoprotein cholesterol, triglycerides, and the ratio of cholesterol to high density lipoprotein cholesterol, with higher antagonistic hostility scores associated with higher levels. Neurotic hostility did not predict lipids. Results suggest a potential pathophysiological mechanism that may contribute to the association between hostility and coronary heart disease. Moreover, a measure of antagonistic hostility, relative to cynical and neurotic hostility, was the best predictor of lipid levels.

Cardiovascular reactivity among hostile men and women: the effects of sex and anger suppression.

This study examined cardiovascular reactivity differences among hostile men and women. Sixty-four individuals (33 women 31 men; M = 19.9 years of age) were selected from a sample of 105 volunteers based on their Cook-Medley Hostility Scale scores (Cook & Medley, 1954; less than or equal to 24). Analyses revealed no significant sex differences in Cook-Medley Hostility scores. At baseline, men had higher mean systolic blood pressure (SBP) level. However, during the Stroop Color-Word Conflict Task (Stroop, 1935), high-hostile men and women exhibited similar cardiovascular responses. Further analyses revealed that cardiovascular responses to the Stroop task were differentially associated with among men and women as a function of anger suppression. For women, anger suppression was positively associated with diastolic blood pressure (DBP) responses and negatively associated with SBP responses. In contrast, anger suppression was negatively associated with DBP changes and not associated with SBP responses for men. The results suggest that personality factors, such as high hostility and anger suppression, may influence the degree to which men and women differ in their cardiovascular responses to interpersonal stressors.

Gender and cardiovascular responses: what is the role of hostility?

Two experiments are reported investigating hostility group by gender effects on heart rate and blood pressure. In experiment 1, 58 males and 59 females were tested with a protocol that included baseline, reaction time with and without harassment, and recovery. In experiment 2, 55 males and 50 females participated in a procedure of baseline, Stroop color--word conflict, anger recall interview, and recovery. Based on Buss-Durkee subscales, genders were divided into high and low neurotic hostility and expressed hostility groups. High expressed hostility was associated with greater diastolic reactivity to all tasks in males, but not in females. Low expressed hostility was associated with greater heart rate and systolic reactivity, specifically during the anger recall interview. High neurotic hostility in males and females was associated with greater diastolic reactivity to the anger task only, while low Neurotic hostility males had higher resting systolic pressures. These results suggest that outward expression of hostility in men may increase their coronary heart disease risk; however, results for both men and women support an association between cardiovascular reactivity and a lack of match between self-reported anger management style and task demands.

Long-term sequelae of childhood sexual abuse: perceived family environment, psychopathology, and dissociation.

In this study, 105 abused and nonabused women were examined for patterns of adult psychopathology associated with childhood sexual abuse and to test the extent to which these patterns are independent of other pathogenic properties of the family environment. Clinical and nonclinical Ss completed the Family Environment Scale, the Minnesota Multiphasic Personality Inventory (MMPI), the Rorschach, and the Stanford Hypnotic Susceptibility Scale. Greater nonspecific impairment among abused women may be a consequence, at least in part, of pathogenic family structure rather than sexual abuse per se. However, MMPI and Rorschach responses suggest sexual abuse may render victims especially vulnerable to specific disturbances i involving soma and self. Abuse was associated with greater use of dissociation, but covariance analysis revealed this effect to be accounted for by family pathology. There was no evidence that sexual trauma is associated with hypnotizability.

The relationship of parenting styles and social competency to Type A behavior in children.

This study examined parenting styles, Type A behavior in parents and children, and social competence in children. Fifty 1st-6th grade children, parents, and their teachers participated. Type A behavior in parents was associated with a controlling style of parenting, but not with pressuring the child to achieve. Parenting styles of achievement pressure and high control were related to impatient and aggressive behaviors in children, as measured by the MYTH, a teacher-scored Type A behavior instrument. In addition, impatience and aggressiveness in the children were negatively correlated with the child's social competency and ability to function in school. Parenting practices, Type A behavior, and social competency in children may play important roles in the origins of detrimental components of Type A behavior, such as impatience and aggression.
