Objective: To examine the cross-sectional associations of Big Five personality traits with midlife allostatic load, including the role of sex, socio-demographic factors and health-related behaviours.
Design: Cross-sectional analyses of 5512 members of the Copenhagen Aging and Midlife Biobank, aged 49–63 years, 69% men.
Main outcome measure: Allostatic load (AL) based on 14 biomarkers representing the inflammatory, cardiovascular and metabolic system.
Results: Due to significant sex?×?trait interactions, analyses were stratified by sex. Openness and Conscientiousness were inversely associated with AL in both sexes, and Extraversion was positively associated with AL in men. Adjusting for socio-demographic factors significantly attenuated the association of Openness in both sexes and of Extraversion in men, for whom the inverse association of Agreeableness with AL was strengthened. Further adjusting for health-related behaviours, the Conscientiousness-AL association was attenuated but remained significant, and Agreeableness remained significantly associated with AL in men.
Conclusion: Results imply that higher levels of Agreeableness (in men) and Conscientiousness are associated with lower levels of AL above and beyond socio-demographic factors and health-related behaviours. The study further contributes by demonstrating the relevance of sex?×?trait and trait?×?trait interactions in the personality-health literature. 相似文献
This study examines whether the relationship between ethical leadership and organizational citizenship behaviours (OCBs) is contingent on organizational identification. Drawing on substitutes for leadership theory, the study proposes that the relationship between ethical leadership and OCBs will be attenuated when employees strongly identify with their organization. Using a sample of Egyptian banking sector employees, this proposition was tested with hierarchal linear modelling (HLM). The results revealed that the positive relationship between ethical leadership and OCBs was stronger for those lower in organizational identification than for those higher in identification. Overall, the findings of the study shed new light on the conditions through which ethical leadership enhances OCBs. 相似文献
Abstract One aim of antenatal preparation is developing coping strategies for use (luring labour. However, the existing literature suggests that attendance at classes is not associated with lower pain or distress, possibly because receiving training cannot be assumed to be associated with subsequent practice. This study aimed to assess whether attenders at classes actually used their taught strategies in their labours, whether use was associated with psychological benefits and whether antenatal measures could predict subsequent use. Concepts from the theories of planned behaviour and self efficacy were used to attempt to predict use of three types of coping strategy. Use was high for breathing strategies but poor for relaxation and posture. Proportion of use of breathing and relaxation showed weak associations with lower fear. Whilst intentions did act as significant predictors for use of posture and relaxation only small proportions of the variance were accounted for and other antenatal measures showed little predictive capacity. Reasons why women in labour may fail to take behavioural consequences from their antenatal beliefs are considered. Predicting health-related behaviours where maintenance rather than just initiation is involved may require greater consideration of intra-situational and emotional factors. Modifications of antenatal preparation to facilitate use of strategies are discussed. 相似文献
Previous studies have demonstrated a linear relationship between self‐control and emotional and behavioural problems. However, some scholars have assumed that both under‐control and over‐control may result in undesired problems, which implies a U‐shaped relationship between them. This issue was reexamined in three Chinese samples in the present study. Self‐report measures that conceptually assessed self‐control and emotional (i.e. depression and negative emotion) and behavioural (i.e. rule‐breaking behaviour, aggression and counterproductive work behaviour) problems were administered to adolescents (N = 885), university students (N = 671) and employees (N = 500). Results of piecewise linear regression show that there were significant quadratic effects of self‐control on emotional and behavioural problems in adolescents and on behavioural problems in employees, but no significant U‐shaped associations between them were found. Implications for future studies are discussed. 相似文献
Objectives: To use the Theory of Planned Behaviour to explore factors associated with performing skin care behaviors and the occurrence of pressure sores in people with spinal cord injury. Design: A within-group cross-sectional design was used to assess 59 people with spinal cord injury living in the community. Of these, 17 participants returned a repeat assessment allowing a longitudinal examination of the relationship between intention and actual behaviour. Methods: A measure was developed in accordance with the Theory of Planned Behaviour guidelines through interviews with people with spinal cord injury. Measures of mood and knowledge of skin care behaviour were also included. Results: The Theory of Planned Behaviour components, mood and knowledge of skin behaviours predicted intention, skin care behaviour and occurrence of pressure sores. Knowledge of skin care was negatively correlated with occurrence of pressure sores (r=−.38, p < .01). Indirect perceived control was a particularly important predictor of pressure relief, accounting for 24% of the variance. Conclusions: Psychosocial factors, including the Theory of Planned Behaviour components, predicted skin care behaviours and the occurrence of pressure sores. These findings provide empirical support for the Theory of Planned Behaviour. The study also carries clinical implications for skin care education for people with SCI and their families. 相似文献
The aims of this study were to investigate variables that influence AIDS-related stigma and to assess occupational risks, behavioural change, and career objectives of students in face of the AIDS epidemic. Data available on 150 randomly selected medical students were analysed statistically. Results indicated that sex and year of study significantly influenced AIDS-related stigma while age, religion and tribe did not. The majority of students recommended screening and health education for high-risk people and reported high levels of perceived risk. Various occupational hazards and behavioural changes were reported, but students still wanted to remain in the medical profession. Implications of these findings are discussed. 相似文献
In a random sample from the general population (N = 2781, 46% males), a longitudinal survey was conducted. The association between dispositional self-control and changes in eating behaviours and diet quality was analysed between the first wave (2010) and the last wave (2014). Results show that the higher the dispositional self-control, the lower the increase in overeating behaviours (emotional eating, external eating, ambivalence towards palatable food and overeating), and BMI and the larger the improvement in healthy diet over time. Self-control was not associated with changes in dietary restraint. This is one of the first studies suggesting that dispositional self-control is associated with changes in eating behaviours and healthy food intake over time. 相似文献
