Female athletes experience pressure to conform to social and sporting norms concerning body weight. This study compared general and sporting body dissatisfaction and disordered eating symptomatology among 320 elite, recreational, and noncompetitive female athletes aged 17 to 30 years competing in leanness focused sports and nonleanness focused sports. Participants completed an online questionnaire including demographic questions, the Eating Attitudes Test, and the Figure Rating Scale. Athletes from leanness focused sports reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of participation level. Elite athletes reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of sport type, and differences between recreational and noncompetitive athletes were not found. More than 60% of elite athletes from leanness focused and nonleanness focused sports reported pressure from coaches concerning body shape. The findings have important implications for identifying risk factors for eating disorders among female athletes, where athletes who compete at elite level and those who compete in leanness focused sports at any level may be at higher risk for developing eating disorders.  相似文献

Socioemotional selectivity theory proposes that older adults emphasize emotional goals and interpersonal closeness to a greater extent than do younger adults, suggesting that holding social work-related values (SWVs) may be beneficial to older employees. This project aimed at examining two dimensions of SWVs, intrinsic and extrinsic SWVs, and tested whether age and work situation would moderate their effects on self-rated job performance. A cross-sectional survey (Study 1, N = 357) and a 14-day experience sampling study (Study 2, N = 77) were conducted among Chinese managerial employees. Study 1 showed that the direct effect of intrinsic SWVs on self-rated job performance was stronger in older employees than in younger employees. Study 2 demonstrated that older employees who valued intrinsic SWVs while being in social situations performed much better than when they did not value intrinsic SWVs but being in social situations; however such positive effect was not shown in younger employees. Findings of this project reveal that the effect of SWVs varies across locus of effect (intrinsic versus extrinsic), age, and work situation. Among older employees, the positive effect of intrinsic SWVs is more crucial than that of extrinsic SWVs on self-rated job performance. Findings of this project imply that intrinsically rewarding incentives would be more effective in motivating older employees to reach peak performance.  相似文献

Background and Objectives: The present study tries to gain more insight in workaholism by investigating its antecedents and consequences using the job demands-resources model. Design: We hypothesized that job demands would be positively related to workaholism, particularly when job resources are low. In addition, we hypothesized that workaholism would be positively related to negative outcomes in three important life domains: health, family, and work. Methods: The research involved 617 Italian workers (employees and self-employed). To test the hypotheses we applied structural equation modeling (SEM) and moderated structural equation modeling (MSEM) using Mplus 6. Results: The results of SEM showed a good model where workload, cognitive demands, emotional demands, and customer-related social stressors were positively related to workaholism and work–family conflict (WFC) (partial mediation). Additionally, workaholism was indirectly related to exhaustion and intentions to change jobs through WFC. Moreover, MSEM analyses confirmed that job resources (job security and opportunities for development) buffered the relationship between job demands and workaholism. Particularly, the interaction effects were statistically significant in five out of eight combinations. Conclusions: These findings suggest that workaholism is a function of a suboptimal work environment and predicts unfavorable employee outcomes. We discuss the theoretical and practical implications of these findings.  相似文献

Physician shortage and turnover are major problems worldwide. On-call duties may be among the risk factors of high turnover rates among physicians. We investigated whether having on-call duties is associated with physicians’ turnover intention and whether job strain variables moderate this association. The present study was a cross-sectional questionnaire study among 3324 (61.6% women) Finnish physicians. The analyses were conducted using analyses of covariance adjusted for age, gender, response format, specialization status and employment sector. The results showed that job strain moderated the association between being on-call and turnover intention. The highest levels of turnover intention were among those who had on-call duties and high level of job strain characterized by high demands and low control opportunities. The lowest levels of turnover intention were among those who were not on-call and who had low strain involving low demands and high control. Also, job demands moderated the association between being on-call and turnover intention; turnover intention levels were higher among those with on-call duties and high demands than those being on-call and low demands. To conclude, working on-call was related to physicians’ turnover intention particularly in those with high job strain. Health care organizations should focus more attention on working arrangements and scheduling of on-call work, provide a suitable working pace and implement means to increase physicians’ participation and control over their job.  相似文献

It is well-known that recovery from work and job resources can counteract negative effects of high job demands, but less is known about how off-job recovery and job resources are related to each other. In this two-level daily diary study, 67 employees filled out daily surveys over the course of 8 days to examine this issue. Consistent with our expectations, multilevel analyses revealed that previous day’s detachment from work is positively related to the state of being recovered before going to work, and that the state of being recovered is positively related to one’s level of job resources. Moreover, the results indicated that both person-level differences and day-level dynamics play a role in these relations. Our study highlights the importance of recovering from work in the sense that it does not only help individuals by repairing negative strain effects but can also function as a catalyst in the activation of job resources.  相似文献

The interest in flexible job search behaviour (FJSB) among unemployed jobseekers, i.e., the extent to which jobseekers also look for jobs that deviate from their studies and earlier work experience, has grown considerably in recent years. Yet, there is large disagreement on both its consequences and drivers. Career scholars as well as policymakers believe that FJSB is important for unemployed and can improve their employment prospects. However, evidence from human resource (HR) literature raises doubts whether FJSB can enhance re-employment success. Similarly, whereas the career literature links FJSB to positive attitudes, such as career adaptability, the HR literature suggests that people searching flexibly may feel pushed into this behaviour due to more negative reasons, like few labour market perspectives. The aim of this study is examining these opposing expectations. We focus on three FJSB types: flexibility with respect to pay/hierarchical level, skill use and commuting time. Hypotheses are tested using two-wave data with 672 unemployed. Results indicate, among others, that career-adaptable people are not inclined to search more flexibly. In addition, FJSB may in certain cases hamper people’s re-employment likelihood. People searching more flexibly also more often became underemployed and as such experienced a more negative job quality.  相似文献

Body dissatisfaction predicts eating disorder symptomatology for some women but not for others. To better understand this disparity, the authors interviewed 7 college women who reported body dissatisfaction and no engagement in eating disorder symptoms. The authors identified 4 factors that may protect body‐dissatisfied women from engaging in eating disorder symptoms.  相似文献

Analyzing the development of the consequences of voluntary job changes in Germany between 1985 and 2013, the study focuses on income gains and job satisfaction increases. Drawing on arguments of the job-search literature on the one hand and the proliferation of choices on the other we investigate whether the returns of job changes have increased or decreased. Results show that income gains have decreased over time while the job satisfaction surplus has remained stable. We further conclude that in determining the outcomes of job changes over time, structural factors seem to be more important than individual ones.  相似文献

Abstract : This study investigated the influence of job type (line or staff) on perceptions of management‐by‐objectives (MBO) effectiveness, goal commitment, and goal‐attainment behavior, as well as mediating effects of perceptions of MBO effectiveness and goal commitment and moderating effects of supervisor behavior. Participants were 152 employees of a factory that manufactures drugs for a Japanese pharmaceutical company. The primary duties of line personnel involved production. The duties of staff personnel who supported production included supplying materials and production planning. Results indicated that line personnel perceived MBO as a more effective system for improving individual performance and showed higher goal commitment and more active behavior related to goals than staff personnel. Although perception of MBO effectiveness was related to goal commitment, it had no mediating effect. Goal commitment mediated between job type and goal‐attainment behavior. Supervisors’ goal‐setting behavior had different positive effects on goal commitment and goal‐attainment behavior for those in line and staff positions. MBO was a better fit for line positions than staff positions. However, supervisor behavior increased goal‐attainment behavior in staff positions. The results indicated that it is important for supervisors in a business organization to operate a management system flexibly.  相似文献
