A total of 119 clinically stable patients with symptomatic congestive heart failure (34 females, 85 males) were recruited from an outpatient hospital practice to explore the role of objective health indicators and neuroticism in subjective health (physical limitations) and psychological well-being. Patients were grouped according to the New York Heart Association functional class criteria (NYHA: indicator of functional status) and proatrial natriuretic factor (proANF), a cardiac hormone that maintains normal fluid balance and vascular resistance. Scores on these two objective indicators of disease severity were generally unrelated to psychological measures, whereas neuroticism scores (EPQ-N) were significantly correlated with indicators of subjective health (perceived disease-related physical limitations) and psychological well-being (depression, general life-satisfaction). Significant interactions between proANF and neuroticism appear due to low physical limitation score among subjects with elevated level of proANF and low scores on neuroticism. High physical limitation was reported by subjects with high level of proANF as well as high scores on neuroticism. Moreover, a marginal significant interaction between NYHA and EPQ-N scores in relation to severity of depression was detected by analyses from two-way ANOVA. Gender differences were due to higher proANF scores in males than females, whereas females scored higher than males on EPQ-N, perceived physical limitation and depression. Results from path analyses supported an indirect effect of neuroticism via perceived physical limitation for males. Possible mechanisms involved in these relations are discussed.  相似文献

心算对内外倾者的心率、T波幅度和呼吸频率的影响   总被引:10,自引:4,他引:6  
该文旨在探讨内、外倾者在三种不同难度心算时,心率、T波幅度、呼吸频率变化的差异。通过艾森克个性问卷筛选出15名内倾者和15名外倾者作为被试,让其完成三种不同难度的心算任务。实验结果表明,心算时两组被试心率均显著上升,内倾组上升幅度大于外倾组;T波幅度显著降低,内倾组降低幅度大于外倾组但差异不显著;呼吸频率显著上升,但两组上升幅度差异不显著。此外,从心率变化上看,两组被试对心算均表现出适应,内倾组的适应速度比外倾组慢。本实验表明,焦虑性精神紧张比智力操作性精神紧张对心率的影响更大。  相似文献

Abstract: The present study examined both human and horse heart rates (HRs) when humans stroked horses for 90 seconds; the subjective arousal levels of the humans were measured by the Tohoku Activation Deactivation Adjective Check List before and after stroking horses. Six male subjects with a positive attitude toward companion animals and 6 male subjects with a negative attitude were selected by their scores on the Pet Attitude Scale, and these two groups, together with a third group, of 6 subjects who were male members of the Doshisha University horse-riding club, participated in this experiment. The HRs of the human subjects during the first 10 seconds immediately after the stroking began were significantly higher than those obtained after that period, but these higher levels gradually returned to baseline levels. This tendency appears more clearly in the negative attitude group. The HRs of the horses increased during the first 20 seconds immediately after the human subjects of the NA group started stroking them, but gradually reduced as the stroking continued. The results of subjective arousal levels suggest a decrease in tension by stroking horses. These results suggest that a certain affectional interaction may exist between humans and companion animals.  相似文献

The increased use of bone marrow transplantation (BMT) to treat a variety of cancers has led researchers to study psychological functioning of BMT patients. The majority of studies conducted, however, has focused on adjustment after transplantation. Cancer patients' use of coping strategies before undergoing this procedure may also relate to levels of psychological distress. Our aims were (1) to provide normative coping data, controlling for situation-specific variables with a homogeneous sample, targeted stressor, and fixed time point, using the Ways of Coping Questionnaire; and (2) to identify coping strategies associated with distress before high-dose chemotherapy. Subjects were 49 patients scheduled to receive high-dose chemotherapy and an autologous bone marrow transplant. Consistent with previous coping research, we found that escape-avoidance was related to psychological distress on several measures. Item endorsement analyses of the escape-avoidance subscale suggest that patients may have used more passive than active avoidance strategies. Subsequent participation in a longitudinal study was not affected by initial levels of avoidant coping.  相似文献

Administered measures of functional status, psychological distress, and quality of life to a consecutive series of 48 liver transplant recipients in follow-up clinic. Results showed that nearly total functional recovery was the norm. Thirty-six patients (75%) had a Karnofsky Performance Status (KPS) score of 80–100. Twelve transplant recipients had KPS scores below 80; none were employed, and most had been transplanted within 1 year. In spite of their impaired financial status, eight of these 12 reported being mostly satisfied on the self-report Quality-of-Life Scale (QLS). For the posttransplant sample as a whole, 83% were mostly satisfied with their quality of life. Pre- and posttransplant patient samples were not significantly different in reporting mild emotional distress. Results for the small subgroup with significant objective or subjective problems in achieving acceptable quality of life following liver transplantation were reviewed. Higher than normal emotional distress on the Symptom Checklist (SCL-90-R) was consistently reported by these patients. Prospective studies are needed to identify predictor variables of quality-of-life problems and to develop prevention and rehabilitation interventions.  相似文献

Infant rats (16, 21, and 26 days old) received 3 days of classical conditioning training to Tone/Shock pairings using heart rate as the index of conditioning. The youngest group (16 days old) showed no evidence of conditioning at any stage of acquisition. In the 21- and 26-day-olds, response to the conditioned stimulus (CS) was a deceleration in heart rate during the first day of training. By day 3, the conditioned response (CR) shifted to cardioacceleration. The data were interpreted as offering strong support for a two-stage model of information processing in the infant rat, comprised of a conditioned orienting response in the first stage and a conditioned defensive response in the second.  相似文献

Classical pairings of a sound stilulus with shock elicited larger magnitude and more rapidly conditioned autonomic responses when subjects were responding on variable-interval schedules for food than when they were eating freely available food. The difference was not attributable to changes in control values of heart rate and blood pressure, or to alterations in motor activity, but appeared related to operant suppression.  相似文献

An experiment, designed to overcome shortcomings in previous work, was conducted to investigate the potential symptomatic benefits of relaxation training in the treatment of asthma in children. Fourteen chronic, severely asthmatic children received three sessions in which they rested quietly, followed by five sessions of relaxation training, and finally three sessions of relaxing as trained previously. Pulmonary function was assessed, in a manner far more definitive than in previous studies, before and after each session, and three additional times at 30-minute intervals thereafter. Tension in the frontales muscles, heart and respiration rates, and skin temperature and conductance were also monitored. Heart rate and to some extent muscle tension results tended to confirm the attainment of relaxed states. However, the lung function results failed to substantiate the previous, preliminary findings of a clinically meaningful change in pulmonary function following relaxation. The status of relaxation in the treatment of asthma was discussed.  相似文献

Although serum cholesterol has for several decades been linked to atherosclerosis and coronary heart disease, cardiovascular primary prevention studies that have resulted in low or lowered cholesterol have not reduced total mortality. This finding may be due in part to an increase in mortality from suicides, homicides, and accidents among people with low or lowered serum cholesterol. This article attempts to review the literature on cholesterol and aggressive behavior, examines possible links connecting the two, and suggests an ethnocultural perspective to these connections.  相似文献
