Affective events theory suggests that affective events at work arouse emotional reactions that influence employees’ attitudes and behaviour in the workplace. In the present study, we apply this theoretical framework to clarify the interplay of variables that explain well-being and performance. We analysed the mediating role of positive affect and work engagement between daily uplifts and well-being, and between daily uplifts and performance. Results from a sample of 293 employees revealed that daily uplifts were positively associated with well-being and performance. While the effects of daily uplifts on well-being were fully mediated by positive affect and work engagement, the effects of daily uplifts on performance were only partially mediated by positive affect and work engagement. In both cases, the effect of positive affect was bigger than that of work engagement. The relations explored provide new theoretical elements for models that explain which variables influence well-being and performance in organizational contexts. The implications for employee health and organizational success are discussed.  相似文献

We investigated the role of age and school type on clustering and switching in verbal fluency tasks (VFTs) with Brazilian children. The children were administered unconstrained, phonemic and semantic VFTs with a duration of 150 or 120 s, respectively. Both age and school type influenced all variables and in terms of performance over time. Older children and private school students outperformed the remainder of the sample, with the first 30 s of each VFT usually being the most productive. Although the size of the clusters produced did not differ between groups, the types of clusters did show some variations, with semantic clusters being the most frequent. Our results revealed strong correlations between switching ability and word production in all three VFTs. In conclusion, the executive functions known as planning and cognitive flexibility play a crucial role in word production by organising and facilitating the recall of lexical information from memory.  相似文献

The Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ) is widely used in the English-speaking countries as a measure of sociocultural influences on body image. Aim of this study was to provide validation data for three subscales of a boys’ and girls’ German version of the SATAQ (SATAQ-G). A sample of 819 male and 791 female Swiss adolescents completed the SATAQ-G internalization of body ideals, perceived pressure and awareness subscales. They also completed assessments of body dissatisfaction, weight and shape concerns, drive for thinness, weight and height. Factor analyses replicated the three subscales of the SATAQ for the boys’ as well as for the girls’ version. All three subscales showed good internal consistency. The internalization and pressure subscales indicated acceptable convergent validity. Awareness did not significantly predict body dissatisfaction. The SATAQ-G, particularly the subscales internalization and perceived pressure, seems to be a satisfactory measure of sociocultural influences on body image.  相似文献

In this study, two longitudinal models of early adolescent risky sexual behaviors (RSB) were compared using a pooled sample of 267 Canadian and Italian adolescents (55% females; 53% Canadians) assessed yearly from grade 8 to 10. We focused on parenting practices (monitoring, control, limit setting), adolescent problem behaviors (antisocial behaviors, substance use) and their friends' deviance (antisocial behaviors, substance use) as predictors of condom use frequency and lifetime number of sexual partners. The socialization model postulates that youths' problem behaviors and RSB are behaviors learned within the friendship network where deviancy training can occur. The selection model posits that delinquent youth tend to affiliate with each other, and that RSB is one of many behaviors that can form the basis of selection. Using structural equation modeling, this study showed that the socialization model was the most accurate to explain the emergence of RSB. A full mediation of parenting practices, passing through deviant friends and youths' problem behavior, was observed for condom use. The same process applied to number of sexual partners, but a direct effect for parenting practices was also found.  相似文献

The Experience Sampling Method was used to explore emotions to music as they naturally occurred in everyday life, with a focus on the prevalence of different musical emotions and how such emotions are related to various factors in the listener, the music, and the situation. Thirty-two college students, 20 to 31 years old, carried a palmtop that emitted a sound signal seven times per day at random intervals for 2 weeks. When signaled, participants were required to complete a questionnaire on the palmtop. Results showed that music occurred in 37% of the episodes, and in 64% of the music episodes, the participants reported that the music affected how they felt. Comparisons showed that happiness-elation and nostalgia-longing were more frequent in episodes with musical emotions, whereas anger-irritation, boredom-indifference, and anxiety-fear were more frequent in episodes with nonmusical emotions. The prevalence of specific musical emotions correlated with personality measures and also varied depending on the situation (e.g., current activity, other people present), thus highlighting the need to use representative samples of situations to obtain valid estimates of prevalence.  相似文献

The aim of this study was to develop a questionnaire to measure adjustment of teenagers at soccer training centers, particularly newcomers. The Soccer Trainee Adjustment Scale was adapted from the Institutional Integration Scale and assesses the trainee's adjustment to operating and social activities. The scale was tested on a sample of 136 trainees from four soccer centers. Exploratory analysis indicated that the 13 items formed five factors: peer adjustment, boarding supervisor adjustment, soccer adjustment, scholastic adjustment, and boarding adjustment. These factors had internal consistency reliability ranging from .76 to .94.  相似文献

Home advantage is known to play an important role in the outcome of professional soccer games and to vary considerably worldwide. In the Turkish Super League over the last 12 years, 61.5% of the total points gained have been won by the home team, a figure similar to the worldwide average and to the Premier League in England. It is lower (57.7%) for games played between teams from Istanbul and especially high for games involving teams from cities in the more remote and ethnically distinct parts of Turkey (Van and Diyarbakir). Match performance data show that although home teams in Turkey take 26% more shots at goal than away teams, the success rates for shots do not differ. For fouls and disciplinary cards, home and away teams do not differ significantly in Turkey, a finding that differs from games in England, perhaps due to less referee bias.  相似文献

The aim of the present study was to examine a theoretical model describing the relationships between body shame and body surveillance (components of objectified body consciousness), internalization of the media body ideal, perceived pressure from media, body mass index and body dissatisfaction in Swiss adolescent boys and girls. A sample of 819 boys and 791 girls aged 14–16 years completed self-report measures of the mentioned concepts. As expected, girls had higher body shame and body surveillance than boys. Structural equation modelling supported the proposed model in both boys and girls. The findings suggest processes that may contribute to body dissatisfaction.  相似文献

The research considers three predictors of the intensity of life regrets: (a) whether the regretted behaviour is an action or a failure to act, (b) the severity of its consequences and (c) the extent to which the behaviour was justified. It is hypothesised that the intensity of recent and distant regrets will be predicted by different combinations of these predictors. Regression analyses on regrets reported by 957 French adults support this hypothesis. The intensity of recent regrets is predicted by the consequences of the behaviour, and especially so for actions. The intensity of distant regrets is predicted by the consequences of the behaviour and by its justification, the effect of justification being stronger for actions than for inactions. These results are discussed in relation to both laboratory and field studies of regret. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

In cognitive aging research, the study of a general cognitive factor has been shown to have a substantial explanatory power over the study of isolated tests. The authors aimed at differentiating the impact of gender and education on global cognitive change with age from their differential impact on 4 psychometric tests using a new latent process approach, which intermediates between a single-factor longitudinal model for sum scores and an item-response theory approach for longitudinal data. The analysis was conducted on a sample of 2,228 subjects from PAQUID, a population-based cohort of older adults followed for 13 years with repeated measures of cognition. Adjusted for vascular factors, the analysis confirmed that women performed better in tests involving verbal components, while men performed better in tests involving visuospatial skills. In addition, the model suggested that women had a slightly steeper global cognitive decline with oldest age than men, even after excluding incident dementia or death. Subjects with higher education exhibited a better mean score for the 4 tests, but this difference tended to attenuate with age for tests involving a speed component.  相似文献
