Depression, anxiety, hostility, and physical health

This study assessed the relationship of depression, anxiety, and hostility to physical health in a multicultural student population (N=106). When controlling for a variety of demographic and health risk factors (viz., age, sex, body mass, smoking, alcohol, salt, caffeine, and exercise), hostility, depression, and anxiety were related to higher reported incidences of physical symptoms and somatic illness. Depression and hostility had the strongest relationships with physical health, although the most striking single relationship was between depression and illness. Results suggest that it may be premature to focus our attention on hostility in research on the personality-illness relationship. They also suggest that the health behavior model of the relationship between personality and disease does not provide an adequate explanation, since negative affect was significantly associated with illness even when controlling for a variety of health risk factors. This work was supported, in part, by an intramural grant from the University of Hawaii, #R511.     

Cynical hostility: developmental factors, psychosocial correlates, and health behaviors

Examined potential differences between individuals with high and low Cook and Medley (1954) Hostility (Ho) scale scores in regard to (a) self-esteem and particular developmental experiences; (b) utilization of social support, experience of anger, and the manner in which anger is managed; and (c) potentially health-damaging behaviors. Individuals with high Ho scale scores were found to be low in covert self-esteem and reported behavior on the part of their parents that reflected (a) less genuine acceptance, (b) more interference in the person's desires as a child, and (c) more punitiveness. In addition, the results indicated that high Ho score individuals avoid seeking or accepting social support, experience anger that is excessive and that occurs in a wide variety of situations, and suppress expression of anger. Finally, it was found that hostile individuals tended to drink more alcohol and drive a car more frequently after drinking and to have greater relative weight.     

Depression mediates the relationship between social performance impairment and hostility

The goal of this study was to test depressive symptoms as a mediator between social difficulties and hostility in young adults. Hostility is often a reaction to both intrinsic and extrinsic factors; therefore a greater understanding of contributing factors is needed, especially among emerging adults. College students (n = 608; 408 females, 200 males) self-reported on social difficulties, depression, and hostility. Via exploratory factor analyses, two latent constructs related to social difficulty were identified: social performance and social motivation. Using structural equation modeling, the direct effects found that poor social performance was significantly positively associated with BPAQ Total (β = .44, p < .01). Social motivation was not associated with BPAQ Total (β = −.07, p = .21). Further, depression scores were found to partially mediate the relationship between social performance deficits (β = .34, p < .01; 95% CI = .05–.16), but not social motivation (β = −.06, p > .05; 95% CI = −.04 to .04), and overall aggression. Results are discussed in terms of the influence of negative affect and impaired emotion regulatory processes on hostility as a consequence of social performance deficits.     

Depression, anxiety, and perceived hassles among entering medical students

This study investigated depression and anxiety among students who were entering medical school prior to the onset of their medical curriculum. Entering students reported financial, day-to-day, academic, and time hassles as concerns. Interestingly, the population characteristics of gender, marital status, and ethnicity impacted the type of self-reported hassles indicated by the students. Measurements of depression and anxiety indicated that entering medical school students' emotional status resembles that of the general population. The results suggest that it is the rigors of the medical curriculum that may play an important role in the increased prevalence of depression and anxiety for students during their medical education. Further, students who are entering medical field already have concerns about medical school and are in the process of anticipating the necessary adjustment to the challenges ahead of them. Preventative programming efforts should begin early in medical education and address a wide variety of concerns from academic, to interpersonal relationships and financial worries.     

Relation of anxiety to hostility in the course of inpatient treatment

The purpose of this study was to examine relationships between anxiety and hostility in hospitalized psychiatric patients, with the passage of time. The used psychometric instruments were the state of anxiety subscale (sA) of the Delusions Symptoms States Inventory (DSSI) and the Hostility and Direction of Hostility Questionnaire (HDHQ). The two questionnaires were administered during the first week of admission and completed again before the discharge of the patient. Two groups of patients emerged and were examined according to the sA scores reported on the second measurement. Group I (n = 44) consisted of patients reporting lower anxiety scores on the second measurement and Group II (n = 22) consisted of patients reporting higher anxiety scores on the second measurement. In Group I, the drop of anxiety scores was accompanied by parallel and highly significant drops of all hostility scores. In Group II, the increased anxiety scores were accompanied by non‐significant or marginally significant changes of hostility scores. The notion that hostility and anxiety are positively related was not fully supported. Also, the opposite thesis that there is a negative relationship between anxiety and hostility was not supported. The present study suggests that the levels of anxiety during the course of inpatient treatment are a factor influencing the temporal relationship between anxiety and hostility. Aggr.

Depression, anxiety, and the MCMI-III: construct validity and diagnostic efficiency

This study aimed to enhance knowledge of the construct validity and diagnostic efficiency of the depression- and anxiety-related scales of the MCMI-III (Millon, 1994). The MCMI-III, various concurrent depression and anxiety measures, and an Axis I structured diagnostic interview were administered in a total sample of 696 outpatients with depressive disorders, anxiety disorders, or both. Sound construct validity was found for the Dysthymia and Major Depression clinical syndrome scales and the Avoidant and Depressive personality disorder scales. The validity of the Anxiety scale was poor, showing moderate convergence with panic and worry-related anxiety measures, but problems discriminating from depression. Operating characteristics for discriminating depressed patients from anxious patients were fair for the Major Depression scale, but poor for the Anxiety and Dysthymia scales.     

Depression, anxiety, and resting frontal EEG asymmetry: a meta-analytic review

Emotion-related disturbances, such as depression and anxiety, have been linked to relative right-sided resting frontal electroencephalograph (EEG) asymmetry among adults and infants of afflicted mothers. However, a somewhat inconsistent pattern of findings has emerged. A meta-analysis was undertaken to (a) evaluate the magnitude of effects across EEG studies of resting frontal asymmetry and depression, anxiety, and comorbid depression and anxiety and (b) determine whether certain moderator variables could help reconcile inconsistent findings. Moderate effects of similar magnitude were obtained for the depression and anxiety studies, whereas a smaller effect emerged for comorbid studies. Three moderating variables predicted effect sizes: (a) Shorter EEG recording periods were associated with larger effects among adults, (b) different operationalizations of depression yielded effects of marginally different magnitudes, and (c) younger infant samples showed larger effects than older ones. The current data support a link between resting frontal EEG asymmetry and depression and anxiety and provide a partial account of inconsistent findings across studies.     

Religiosity, psychological resources, and physical health

Various explanations have been given for the positive association between religiosity and physical health. Using data from two waves of the National Survey of Midlife in the United States (1995, 2005) and retrospective data on the importance of religion in the home in which respondents were raised we find that psychological resources, operationalized by measures of emotional and psychological well-being, mediate the effect of this early exposure to religion but only on self-rated health and physical symptomatology; chronic illnesses and health limitations on activities of daily living are unaffected.     

Direct and indirect relationships among posttraumatic stress disorder,depression, hostility,anger, and verbal and physical aggression in returning veterans

Hostility, anger, and aggression are conceptually related but unique constructs found to occur more often among veterans with posttraumatic stress disorder (PTSD) than among civilians or veterans without PTSD. However, the pathways between PTSD, depression, hostility, anger, and aggression have not been comprehensively characterized. Therefore, drawing on a sample of returning Operation Enduring Freedom/Operation Iraqi Freedom combat veterans ( N = 175; 95% male; mean age 30 years), this study sought to examine the direct and indirect relationships among PTSD, depression, hostility, anger, and four types of aggression: verbal, and physical toward self, others, and objects. Functional modeling of direct effects was done using multiple least-squares regression and bootstrapped mediation analyses were carried out to test indirect effects. Results indicate that PTSD is not the overall direct contributor to different forms of aggression, supporting the mediating role of depression and trait anger. Depression symptoms explain part of the relationships between PTSD and verbal aggression, physical aggression toward objects, and physical aggression toward self and trait anger explains part of the relationships between PTSD and verbal aggression, physical aggression toward objects, and physical aggression toward others. Our findings support the importance of assessing for anger, depression, and different types of aggression among veterans presenting for PTSD treatment to develop individualized treatment plans that may benefit from early incorporation of interventions.     

Exclusion,intergroup hostility,and religious fundamentalism

The goal of the present study was to examine whether exclusion leads to increased intergroup hostility and stronger fundamentalist religious beliefs. Using Cyberball, we examined how adolescents from different ethnic groups in the Netherlands (of Moroccan, Turkish, and Dutch descent with either Muslim, Christian, or secular beliefs) responded to being included or excluded by ethnic in- and outgroup members. We expected that exclusion by ethnic outgroup members would represent a categorization threat and would result in greater hostility. We hypothesized that exclusion by ethnic ingroup members would represent an acceptance threat and would result in responses that reduce uncertainty and increase one's chances of being accepted by others (e.g., a stronger endorsement of fundamentalist religious beliefs). The results revealed that among all ethnic groups, exclusion by ethnic outgroup members led to more hostility toward the co-players and the co-players' ethnic group than exclusion by ethnic ingroup members. This was mediated by the extent to which people attributed their exclusion to the racist attitudes of their co-players. Among Muslims and Christians, exclusion by ethnic ingroup members led to more support for fundamentalist beliefs. We discuss the theoretical extension that these results provide, and practical issues raised regarding the consequences that may occur through the marginalization of religious and ethnic groups.
