Work-Induced Changes in Feelings of Mastery

ABSTRACT

Past theory and research indicate that conditions of work can have lasting effects on job incumbents. R. A. Karasek and T. Theorell (1990) Karasek, R. A. and Theorell, T. 1990. Healthy work: Stress, productivity, and the reconstruction of working life, New York: Basic Books.  [Google Scholar], for example, proposed that workers’ feelings of mastery increase with levels of job demands and job control, and that these effects are mediated by the process of active learning. To test these propositions, 657 school teachers completed scales assessing job demands, control, active learning, and mastery on 2 occasions, 8 months apart. As hypothesized, job control predicted change in mastery, an effect that was mediated by active learning. Job demands had a weaker effect on change in mastery. The demands–mastery relationship was moderated by job control, so that under conditions of high control, but not low control, increasing job demands were associated with gains in mastery. The findings partially support R. A. Karasek and T. Theorell's (1990) predictions regarding the main, interactive, and mediated effects of job conditions on employee mastery.     

Occupational stress of professional nurses in South Africa

The objective of this study was to identify occupational stressors for professional nurses in South Africa. A cross-sectional survey design was used. A stratified random sample of professional nurses (n=818; females?=?97%) in hospitals in South Africa was used. The Nursing Stress Indicator (NSI) was administrated together with a biographical questionnaire. Three internally consistent stress factors, namely lack of organisational support, job demands and nursing-specific demands, were extracted. The most severe stressors for professional nurses included staff shortages, inadequate salaries and excessive administrative duties. Work overload, fellow workers not doing their job, health risks posed by contact with patients and demands of patients were also identified as stressors. Stress was associated with specific factors, including age, position (rank), care unit, and work experience.     

Pathways to flourishing among pharmacy students: The role of study demands and lecturer support

This study investigated possible pathways to flourishing among pharmacy students attending a South African university (N = 799; females = 81.6%; Afrikaans-speakers = 84.7%, mean age = 20.42 years, SD = 2.25 years). The students completed the Mental Health Continuum – Short Form (MHC-SF) and an Overload and Lecturer Support Survey. Of the 779 pharmacy students, 40.3% self-reported as flourishing, with high mean scores on workload and lecturer support. The level of emotional well-being of year group 2 was the highest. Following structural equation modelling, overload and lecturer support explained between 18% and 31% of the variance in the flourishing of the different year groups. From the second to the third year, the predictive value of overload and lecturer support for flourishing decreased by 8.8%. Lecturer support and low overload appear to play a positive role in the flourishing of higher education students.     

Demands,resources, and work ability: A cross-national examination of health care workers

Understanding work ability, with the goal of promoting it, is important for individuals as well as organizations. It is especially important to study work ability in health care workers, who face many work-related challenges that may threaten work ability. We studied various job demands, job resources, and interactions of demands and resources relating to work ability using the Job Demands–Resources model as a framework. Acute care health care workers from six nations (US, Australia, UK, Brazil, Croatia, and Poland) completed a survey. Role demands related to work ability in the Australia sample only, and supervisor support related to work ability in the Australia sample only. Yet, high levels of supervisor support significantly moderated (buffered) negative relationships between physical demands and work ability in the US sample, along with negative relationships between role demands and work ability in both the Croatia and UK samples. Skill discretion related to work ability in every nation sample, and therefore appears to be particularly important to work ability perceptions. In addition, skill discretion moderated (buffered) a negative relationship between role demands and work ability in the Australia sample. We therefore recommend that interventions to help preserve or improve work ability target this important job resource.     

Associations between rating content and self-other agreement in multi-source feedback

In a study of the ratings of managers' behaviour made by themselves, their supervisors, subordinates, and peers, it was found that degree of similarity between self-ratings and ratings by colleagues was significantly associated with three aspects of rating content: the observability of a behaviour, its desirability, and the degree to which it concerned technical rather than interpersonal activities. However, these associations with rating content depended on which of two indices of between-rater similarity was studied, in terms of either the correlation or the difference between ratings. The desirability of behaviour more influenced correlation measures of similarity, and the type of behaviour had more influence on difference scores: managers over-rated their interpersonal activities but not their technical effectiveness.     

How do job characteristics contribute to burnout? Exploring the distinct mediating roles of perceived autonomy,competence, and relatedness

This study aimed to better understand the psychological mechanisms, referred to in the job demands–resources model as the energetic and motivational processes, that can explain relationships between job demands (role overload and ambiguity), job resources (job control and social support), and burnout (emotional exhaustion, depersonalization, and personal accomplishment). Drawing on self-determination theory, we examined whether psychological resources (perceived autonomy, competence, and relatedness) act as specific mediators between particular job demands and burnout as well as between job resources and burnout. Participants were 356 school board employees. Results of the structural equation analyses provide support for our hypothesized model, which proposes that certain job demands and resources are involved in both the energetic and motivational processes—given their relationships with psychological resources—and that they distinctively predict burnout components. Implications for burnout research and management practices are discussed.     

Savoring as a Moderator of the Daily Demands and Psychological Capital Relationship: A Daily Diary Study

ABSTRACT

The present study examined daily savoring as a moderator of the relationship between daily demands and daily psychological capital (PsyCap), a collective term referring to the positive psychological states of hope, optimism, resilience, and self-efficacy. A sample of university students (N = 109) responded to nightly online surveys over the course of eight days. Results showed that daily uplifts and savoring were positively related to overall daily PsyCap, as well as each individual dimension of the PsyCap. Daily demands were negatively related to PsyCap and each dimension of PsyCap. Additionally, daily savoring significantly interacted with daily demands to predict overall PsyCap, as well as the individual dimensions of optimism and resilience. Specifically, the negative relationship between daily demands and PsyCap was reduced when individuals engaged in greater savoring. The discussion focuses on the role of savoring in responding to demands and the mechanisms linking higher savoring to greater PsyCap on demanding days.     

对热休克反应的哲学思考

生物细胞在受到各种有害因素刺激后,会发生一种应激反应,其间细胞内的正常蛋白质合成受抑,而合成一些新的蛋白质,这种现象及所合成的蛋白质被称之为热休克反应和热休克蛋白。研究发现,热休克反应是生物细胞对环境因素的适应性反应,并广泛存在于从原核到真核生物的生物体内。对人类而言,其功能是多样的,利弊共存,形成了相互联系相互转化的对立统一关系     

Effects of perceived social support and family demands on college students' mental well‐being: A cross‐cultural investigation

The effects of perceived social support and family demands on college students' mental well‐being (perceived stress and depression) were assessed in 2 samples of Jordanian and Turkish college students. Statistically significant negative correlations were found between perceived support and mental well‐being. Multiple regression analyses showed that perceived family support was a better predictor of mental well‐being for Jordanian students, while perceived support from friends was a better predictor of mental well‐being for Turkish students. Perceived family demands were stronger predictors of mental well‐being for participants from both ethnic groups. Jordanian and Turkish participants who perceived their families to be too demanding were more likely to report higher depression and stress levels. None of the interactions between social support or family demands and either of the 2 demographic variables were statistically significant. These findings provide a more nuanced view of the relationship between social support and mental health among college students, and point to the relevance of some cultural and situational factors. They also draw further attention to the detrimental effects of unrealistic family demands and pressures on the mental health of college youths.
