Health-related quality of life (QoL) is an important and widely used outcome measure in cardiac populations. We examined the relationship between positive affect and health-related quality of life, controlling for traditional cardiovascular risk factors, clinical variables and negative affect. We further investigated the role of gender in this relationship given the well-known gender differences in cardiovascular health. We enrolled 746 patients with coronary heart disease (CHD) before they entered outpatient cardiac rehabilitation. All patients completed the Global Mood Scale and the SF-36 Health Survey. Positive affect was independently associated with mental (p < .001) and physical QoL (p < .001) after controlling for control variables. Gender moderated the relationship between positive affect and physical QoL (p = .009) but not mental QoL (p = .60). Positive affect was positively associated with physical QoL in men (p < .001) but not in women (p = .44). The health-related QoL of patients with CHD is associated with a person’s level of positive affect.  相似文献

The author investigates the view that there is a moral obligation to serve in the armed forces of the nation State of which one is a citizen resident (with special reference to young American men at the present time). It is conceded that under current law in this country there may be such a legal obligation, that many men may be obliged to render such service, and that under certain circumstances even a moral obligation to serve may also exist. What is denied is that any of the familiar theories of moral obligation is adequate in existing circumstances to establish this thesis in general. The result is either that a new theory of moral obligation must be developed to fit the current facts, or the present assessment of those facts must be fundamentally revised, or we must concede that draftees and men generally have no such moral obligation of service at all.  相似文献

The present study explored the relationships between psychological and somatic factors in patients undergoing Coronary Artery Bypass Graft surgery (CABG). The data-analysis of previous work was extended by adding somatic factors, including feelings of disability, somatic complaints and fatigue. The focus was on their relationships with psychological factors, including anxiety, depression and neuroticism. Prior to surgery and six months postoperatively, 217 patients completed self-report questionnaires. Using the method of structural equation modeling (SEM), the structure of relationships between the somatic, psychological and background factors (i.e., gender, age and medical factors) was explored. A model was developed providing a good fit and accounting for a substantial amount of variance. The structure of relationships revealed that somatic factors lead to anxiety and depression in the preoperative period, whereas anxiety and depression lead to somatic factors in the postoperative period. The structure further strengthened the key position of neuroticism and its overall negative prognostic implications.  相似文献

The aim of this study was to assess whether Subjective Health Complaints (SHC), demands and coping are associated with health-related quality of life in a population of health care workers. One hundred and nineteen employees in two nursing homes for the elderly filled in a questionnaire on health, exercise, psychological factors, and work conditions. Main outcome measures were SHC and quality of life measured by SF-36. High level of SHC was associated to low health-related quality of life. Low coping and high demands were related to low scores (low quality of life), and high coping and low demands to high scores on mental health. Pseudoneurological complaints (e.g. tiredness, sadness), high demands and low coping were associated with low mental health. The expected negative association between SHC and health-related quality of life was found. There was a positive association between coping and quality of life.  相似文献

According to cognitive-behavioral models of social anxiety disorder (SAD), four of the important maintaining mechanisms are avoidance, self-focused attention, anticipatory processing and post-event cognitive processing. Individual cognitive therapy (ICT) and cognitive behavioral group therapy (CBGT) both have substantial empirical support. However, it is unclear whether they achieve their effects by similar or different mechanisms. The aim of this study was to investigate whether changes in the four maintenance processes mediate clinical improvement in ICT and CBGT for SAD. We analyzed data from participants (N = 94) who received either ICT or CBGT in two separate RCTs. The results showed that ICT had larger effects than CBGT on social anxiety and each of the four potential mediators. More pertinently, moderated mediation analyses revealed significant between-treatment differences. Whereas improvement in ICT was mainly mediated by reductions in avoidance and self-focused attention, improvement in CBGT was mediated by changes in self-focused attention and in anticipatory and post-event processing. These results support the importance of the putative mediators, but suggest that their relative weights are moderated by treatment type.  相似文献

The compensatory model of motivation and volition is based on the assumption that discrepancies between implicit and explicit motives lead to psychological conflict, and that resolution of this conflict requires volitional regulation and consumes volitional strength. This suggests that implicit/explicit motive discrepancies (IED) are responsible for decreases in volitional strength. A longitudinal field study with 82 managers was conducted to test this proposition. Results show that IED longitudinally predicted decreases in volitional strength. Furthermore, structural equation modeling revealed that volitional strength mediated the relation between IED and impaired subjective well-being. The theoretical and practical implications of these results are discussed, particularly with respect to volitional depletion.  相似文献

Social influence on song acquisition was studied in 3 groups of young European starlings raised under different social conditions but with the same auditory experience of adult song. Attentional focusing on preferred partners appears the most likely explanation for differences found in song acquisition in relation to experience, sex, and song categories. Thus, pair-isolated birds learned from each other and not from broadcast live songs, females did not learn from the adult male tutors, and sharing occurred more between socially associated peers. On the contrary, single-isolated birds clearly copied the adult songs that may have been the only source of attention stimulation. Therefore, social preference appears as both a motor for song learning and a potential obstacle for acquisition from nonpreferred partners, including adults.  相似文献

Human subjects represent the location of a point in 2D space using two independent dimensions (x–y in Euclidean or radius-angle in polar space), and encode location in memory along these dimensions using two levels of representation: a fine-grain value and a category. Here we determined whether monkeys possessed the ability to represent location with these two levels of coding. A rhesus monkey was trained to reproduce the location of a dot in a circle by pointing, after a delay period, on the location where a dot was presented. Five different delay periods (0.5–5 s) were used. The results showed that the monkey used a polar coordinate system to represent the fine-grain spatial coding, where the radius and angle of the dots were encoded independently. The variability of the spatial response and reaction time increased with longer delays. Furthermore, the animal was able to form a categorical representation of space that was delay-dependent. The responses avoided the circumference and the center of the circle, defining a categorical radial prototype around one third of the total radial length. This radial category was observed only at delay durations of 3–5 s. Finally, the monkey also formed angular categories with prototypes at the obliques of the quadrants of the circle, avoiding the horizontal and vertical axes. However, these prototypes were only observed at the 5-s delay and on dots lying on the circumference. These results indicate that monkeys may possess spatial cognitive abilities similar to humans.  相似文献
