Cardiovascular and neurohumoral responses to behavioral challenge as a function of race and sex

Cardiovascular and hormonal responses to a structured interview, an electronic video game, a cold pressor test, and exercise on a bicycle ergometer were assessed in eighty-three 25- to 44-year-old normotensive Black and White men and women. Blacks showed significantly greater diastolic blood pressure (DBP) responses than Whites during the cold pressor test, which were not accounted for by an increase in plasma catecholamines. Exercise produced reliably greater systolic blood pressure (SBP) increases in Black women than in Black men or White women. Men showed significantly greater SBP and DBP changes than women during the video game. These findings suggest that the pattern of physiological reactivity elicited by challenge is related to the race and sex of the subjects.     

A PROSPECTIVE STUDY OF SOMATIC AND EMOTIONAL SYMPTOMS OF PREGNANCY

Using a prospective design, this study examined somatic and emotional symptoms of planned pregnancy in a sample of 162 healthy women. All women participated in a baseline (prepregnancy) interview. Seventy women became pregnant and were assessed at each trimester; the 92 nonpregnant controls were interviewed 3, 6, and 9 months after their baseline interview. All participants also completed the Anxiety and Depression subscales of the Symptom Checklist–Revised (SCL 90-R). No significant group differences were found at baseline. As expected, however, pregnant women reported significantly more instances of digestive symptoms (nausea, vomiting, heartburn), fatigue, and moodiness than nonpregnant controls. Discriminant-function analyses found that in the context of all symptom variables, nausea and fatigue were the primary distinguishing features of the first trimester. In the second and third trimester, fatigue and heartburn contributed to the distinction of pregnant and nonpregnant women. Although pregnancy precipitates many physical and psychological changes in this sample of women who had planned pregnancies, our results did not support the notion that pregnancy is either a time of significant emotional turmoil or of heightened emotional well-being.     

Theobiology: An Analysis of Spirituality, Cardiovascular Responses, Stress, Mood, and Physical Health

The relationships of spirituality and religion to acute cardiovascular responses, physical symptoms of illness, stress and psychological mood were assessed in a community sample of adults. Nineteen men and 61 women participated in a betrayal interview, while their blood pressure and heart rate were monitored. Religious affiliation, frequency of attendance at worship and religiousness were associated with resting diastolic and mean arterial pressure. Spirituality, especially as assessed by the existential scale of the Spiritual Well-being Scale, was related to symptoms of illness, medication use, stress and negative mood states. Spirituality and involvement in organized religion may represent a means to increase the sense of purpose and meaning in life, which is related to greater resiliency and resistance to stress-related illness.     

Cardiovascular intraindividual variability in later life: the influence of social connectedness and positive emotions

Healthy normotensive men and women (N=33) underwent a 60-day diary assessment of emotions and cardiovascular functioning. Individual differences in social connectedness and mood were measured in questionnaires, and positive emotions, negative emotions, systolic blood pressure (SBP), and diastolic blood pressure (DBP) were assessed daily for 60 consecutive days. Results confirmed that the cardiovascular undoing effect of positive emotions is evident primarily in the context of negative emotional arousal. The daily associations between positive emotions and cardiovascular outcomes were linked to individual differences in social connectedness. Controlling for individual differences in mood levels, multilevel regression analyses showed that social connectedness predicted extended positive emotion, diminished SBP and DBP reactivity, and more rapid SBP recovery from daily negative emotional states.     

Emotional irritation before mental stress is associated with enhanced peripheral norepinephrine

Research suggests equivocal findings on associations of catecholamines and mood. Our study investigated the associations of emotional state, blood pressure and catecholamines in 55 healthy males undergoing mental stress. We especially checked the reported link between norepinephrine (NE) and emotional irritation. Blood pressure (SBP, DBP) and heart rate (HR) were continuously monitored. NE and epinephrine (EPI) were measured before, after, and 20 minutes after stress. Participants were divided into irritated versus non-irritated and anxious versus non-anxious subjects by median split on their baseline questionnaires. The task elicited significant cardiovascular, hormonal, and psychological stress responses. NE levels were significantly correlated with irritation before stress. Irritated subjects showed significantly higher DBP and NE than non-irritated subjects. The higher NE and DBP levels in the irritated participants suggest detrimental psycho-physiological interrelations promoting the development of stress-mediated cardiovascular diseases. Heightened emotional irritation before stress may be regarded as a psychological risk factor.     

An exploratory analysis of the influence of personality and emotional factors on cerebral blood flow responses during painful stimulation in Fibromyalgia

This study explored the influence of certain personality traits (neuroticism, extraversion, psychoticism, alexithymia), emotional variables (depression, catastrophizing), and insomnia on cerebral blood flow (CBF ) responses to painful stimulation in fibromyalgia, using functional transcranial Doppler sonography. CBF velocities were recorded bilaterally in the anterior cerebral arteries (ACA ) and middle cerebral arteries (MCA ) of 24 fibromyalgia patients during exposure to two painful pressure conditions: (1) fixed pressure (2.4 kg) and (2) an individually calibrated pressure to produce an equal‐moderate subjective pain intensity in all participants (average, 3.5 kg). Psychological factors were assessed by means of questionnaires. Neuroticism, and the externally‐oriented thinking dimension of alexithymia were positively, and extraversion was inversely, associated with specific components of ACA and MCA CBF responses. Regarding catastrophizing and depression, correlations were positive for the fixed pressure condition and negative for the equal subjective intensity condition. The findings suggest that alterations in central nervous pain processing in fibromyalgia vary according to psychological factors. While most of the observed associations reflect a linear increase in nociceptive processing with the magnitude of negative cognitive and emotional states, the inverse associations for catastrophizing and depression during more intense painful stimulation may be ascribed to anti‐nociceptive effects due to activation of the defense reflex.     

Gender differences in cardiovascular and hypothalamic-pituitary-adrenal axis responses to psychological stress in healthy older adult men and women

Gender differences in the neuroendocrine and cardiovascular response to psychological stress may contribute to the gender differences in the prevalence of diseases associated with hypothalamic-pituitary-adrenal (HPA) axis reactivity such as cardiovascular disease (CVD), diabetes and hypertension. We measured plasma ACTH, cortisol, heart rate (HR), and blood pressure (BP) responses in 8 men and 8 women (55-75 years) exposed to the Matt Stress Reactivity Protocol (MSRP), a psychological challenge. The MSRP elicited significant increases in HR, systolic-, and diastolic BP, ACTH and cortisol (all p<0.01). Men had significantly greater cortisol and diastolic BP responses compared to women (p<0.05). Additionally, a positive correlation between the ACTH and cortisol responses was only found in the males (r=0.71, p<0.05). There were no group differences in HR, systolic BP, or ACTH responses. We conclude, that among older adults, men respond to psychological stress with greater increases in cortisol, compared to women. This greater activation of the HPA axis could translate into an elevated risk for CVD, diabetes and hypertension and may be related to the higher prevalence of these diseases in males. Gender differences in brain structures and/or cognitive processes may be responsible for these sexually dimorphic stress responses.     

Chronic stress influences cardiovascular and neuroendocrine responses during acute stress and recovery, especially in men.

This study tests the influence of chronic stress on cardiovascular and neuroendocrine responses to and recovery from acute stressors and whether the effects are gender specific. Sixty-two healthy, middle-aged persons (50% women) performed mental-arithmetic and public-speaking tasks and relaxed thereafter for 1 hr while their cardiovascular and neuroendocrine function was measured. Participants with higher levels of chronic stress showed lower systolic blood pressure (SBP) and epinephrine (E; men only) and marginally lower levels of norepinephrine (NE) responses to the tasks and showed lower levels of cortisol and marginally lower NE responses during recovery. Relative to women, men had high diastolic blood pressure (DBP) responses to the tasks and high SBP, DBP, and E responses during recovery. Gender differences in cardiovascular disease in midlife may be due to gender differences in the inability to recover quickly, in addition to enhanced acute-stress response.     

Illness representations and emotion in people with abnormal screening results

The present study examined the relationship of cognitive and emotional representations of illness specified by self-regulation theory on emotional responses of patients with abnormal screening results. Participants were 660 women who received an abnormal cervical smear and 701 men and women who received an abnormal colorectal cancer screening result. Participants completed postal questionnaires containing measures of illness representations and specific emotions. Factor analyses of cause components produced three factors for each sample, corresponding to psychological stress, biological, and behavioural causes. Regression analyses showed that, after controlling for demographic variables, perceived consequences, illness identity, and causal attributions to psychological stress explained significant variance in emotion. Emotional representations also accounted for unique variance in emotional responses. Results indicate congruence in the relationships between illness representations of an emotionally salient event and emotion in patients from the two cancer screening programmes and support the internal validity of self-regulation theory.     

Hormonal and psychological effects of examination stress

Twelve undergraduate students were tested to determine the effects of examination stress on psychological and endocrine variables. Testing was undertaken six weeks prior to a final written examination (phase I), at the time of the examination (phase II), and 12–14 days after the examination (phase III). A control group consisted of students not taking an examination. The results demonstrated an increase in state anxiety, global stress level, systolic blood pressure and serum prolactin during stress (i.e. in phase II). In phase III, the psychological responses were normalized, but both systolic and diastolic blood pressure as well as serum prolactin, were still elevated.     

Disrupted Transition to Parenthood: Gender Moderates the Association Between Miscarriage and Uncertainty About Conception

Miscarriage is a devastating yet common experience shared by women and their partners. Doctors often recommend that couples attempt to conceive again after the experience of a miscarriage, yet little is known about the emotional toll of conception following miscarriage. In the current study, we addressed two primary research questions: (a) How does experiencing a miscarriage relate to recalled emotional experiences of uncertainty surrounding efforts to conceive again? and (b) does gender moderate the association between miscarriage and retrospective accounts of emotions surrounding efforts to conceive? An online sample of parents from across the U.S. (N?=?429; 84.4 % married or cohabiting) reported their number of prior miscarriages and completed online questionnaires assessing recalled psychological adjustment (anxiety, rumination, positive and negative emotions) during their efforts to conceive their youngest child. In addition, they provided written responses regarding their experiences during this time. Participants’ responses were quantitatively analyzed for word use using LIWC, a text-analysis software program, to obtain an observational indicator of emotions. For women but not men, miscarriage was associated with recalled anxiety, rumination, and negative emotions surrounding efforts to conceive a child, as well as the use of more negative emotion, sadness, and anxiety words when describing efforts to conceive. Thus, miscarriage seemed to taint the emotional experience of trying to conceive again, and this consequence seemed particularly poignant for women.     

Mothers' psychological adjustment following disaster affecting their children

The authors investigated the psychological adjustment of 37 British women whose adolescent children survived the cruise ship Jupiter's sinking in 1988, about 6 years previously. They compared these women with a group of widows (N = 18) and a group of women who had suffered no major negative life event (N= 15). Psychological adjustment of the 37 women was assessed with the Schedule for Affective Disorders and Schizophrenia Lifetime Version (SADS-L; R. L. Spitzer & J. Endicott, 1975) and various standard questionnaires. The women whose children had been involved in the disaster were found to have suffered a greater number of incidents of psychological distress in the period since the disaster than the women who had suffered no major negative life events but fewer incidents of psychological distress than the widows. The significance of these findings and clinical implications are discussed.

Cardiovascular reactivity to and recovery from psychological challenge as predictors of 3-year change in blood pressure.

The authors examined whether cardiovascular reactivity to and recovery from psychological challenge predict 3-year change in blood pressure (BP) among 216 initially normotensive, community-dwelling adults. Clinic BP assessments were conducted at baseline and follow-up. BP and heart rate (HR) readings were obtained before, during, and after 5 psychological tasks at baseline. Following adjustment for traditional predictors of BP and lifestyle factors, poorer systolic BP recovery across the tasks was associated with greater 3-year increases in clinic systolic and diastolic BP. Both diastolic BP recovery and HR recovery were also related to 3-year change in clinic BP, though cardiovascular reactivity measures were not. These findings suggest that the duration of stress-related cardiovascular responses may be important for predicting longitudinal changes in BP.     

Psychophysiological effects of emotional dissonance in a face-to-face service interaction

Abstract

Current research demonstrates that requirements to express emotions which are not genuinely felt in the particular situation (emotional dissonance) are associated with negative long and short-term effects. The aim of the present study was to investigate: (a) the psychophysiological short-term effects of emotional dissonance in a face-to-face service interaction and (b) the moderating role of gender and neuroticism. In total, 32 women and 27 men were instructed to play the role of a service employee, who had to interact with an angry and rude customer. Half of the sample was given information that the organization expected them to be friendly (emotional dissonance), the other half was told they were expected to act naturally and show their genuine feelings (no emotional dissonance). Subjective and behavioral responses revealed that participants in the “friendly” condition modulated their emotional expressions to a greater extent than those in the “naturally” condition. Participants in the “friendly” condition showed stronger systolic and diastolic blood pressure responses. Furthermore, hierarchical regression analyses yielded that gender and neuroticism partly moderated the association between emotional dissonance and participants' psychophysiological response.

Cardiovascular responses to occupational stress in male medical students: a paradigm for ambulatory monitoring studies.

Hemodynamic responses to systematic variations in occupational stress were examined using ambulatory blood pressure monitors (ABPMs). The goals of this study were (a) to illustrate the effectiveness of employing naturally occurring, controlled variations in psychological stress levels in studies incorporating ABPMs and (b) to document the patterns of cardiovascular responses to acute examination stress in medical students. Heart rate, systolic blood pressure, diastolic blood pressure, rate-pressure product, and mood states were measured before, during, and after low-stress (lecture) and high-stress (examination) work in 44 healthy male medical students. The lecture day was characterized by stable patterns of cardiovascular activity across all three periods. Hemodynamic activity and reports of activation and distress were greater on the examination day than on the lecture day. Cardiovascular activity during the preexamination period was as high as that seen during the examination period itself, indicating an anticipatory stress effect. Pressor activity decreased after the examination, although some residual chronotropic activity was seen. Systematic changes in physiological responses to controlled variations in the level of this naturalistic stressor support the use of this paradigm for other ABPM studies. The elevations in preexamination responses seen here suggest the need to consider prestressor experiences in such studies.     

A prospective study of factors that lead to body dissatisfaction during pregnancy

This study examined changes in body image and predictors of body dissatisfaction during pregnancy. It was expected that higher levels of depression, social comparison tendencies, teasing, societal pressure to be thin and public self-consciousness would predict body dissatisfaction prospectively. Healthy pregnant women (n = 128) completed questionnaires on three occasions during their pregnancies reporting on a total of four time points: 3 months prior to pregnancy (retrospectively reported), in the early to mid-second trimester, the late-second/early-third trimester, and the latter part of the third trimester. For the most part women reported adapting to the changes that occurred in their body; however, women were most likely to experience higher levels of body dissatisfaction in early to mid-second trimester. Findings related to predictors of body dissatisfaction revealed that both social and psychological factors contributed to body image changes in pregnancy. Implications of the findings are discussed.     

THE HIDDEN RAPE VICTIM: PERSONALITY, ATTITUDINAL, AND SITUATIONAL CHARACTERISTICS

A hidden rape victim is one who has never reported her experience to a rape crisis center or to police. It has been estimated that only 10–50% of the rapes that actually occur are ever reported to authorities. Since most previous rape studies have selected samples from official sources, hidden victims have been overlooked. The goals of the present study were to describe the victimization experienced by hidden victims and to determine whether any psychological variables were related to victimization status. The psychological variables examined included personality, attitudinal, and situational characteristics relevant to the three major models of rape victimization: social control, victim precipitation, and situational blame. Subjects were 82 not sexually victimized, 37 low sexually victimized, 50 moderately victimized, and 62 highly sexually victimized women. Subjects completed questionnaires and participated in a one-to-one standardized interview. Data were analyzed via multivariate analysis of variance. Personality variables and attitudes did not differentiate the groups of women, while numerous situational variables did. The theoretical implications of these findings are discussed.
